Filter out lead, heavy-metals, and all the other dangerous toxins

I was hoping to get some of your filters for my home. I don't know which type I need or how it would be installed. There was a story written recently by one of my colleagues here at the Chicago Tribune about troubling lead levels and chromium in the water prompting many people to try and improve their water quality. I was hoping to find a filter that could be made available, not only to myself, but to the many other concerned people who read the article.  Any advice would be greatly appreciated.
 We are a dealer  for Doulton and various other brand filters,   I understand your in need for a good, quality, reliable filter system that filters out lead, heavy-metals, and all the other dangerous toxins in our water today. A recommendation to consider would be our dual housing, undersink Doulton system which will take out those metals, chemicals, and micro-organisms from the water.

Water Filter systems for mission use in Africa

I came across your website online and am very impressed with your water purification products. I am a registered nurse working for a non-profit missions agency in West Africa and have been doing a lot of research on water filters for our members to use. The water here is not potable and cholera is a constant problem in many parts of the country. People here are using the Katadyn "bucket" system, Pentapure systems, and trying out the Sawyer filters. We have found pro's and con's with each system and I am constantly on the lookout for a product that will provide better water quality and that is easy to use.  A couple questions I had for your company are as follows: 
1. Some people report "arthritis-type" of symptoms and pain after longer term use of the Katadyn (often ceradyn candle) system. Have you found complaints like this with your system. I realize that a company does not want to advertise any side-effects or adverse events of heir product, but the reality is that we have to drink filtered water here every day and this last many years for some people if they live here. I think it is important to be aware of some of the long-term effects of use.
2. Does your company offer a purchase price for non-profit organizations, especially if the systems and replacement candles are bought in bulk?
 Thank you for your time and many years of making a quality product.
Doulton has been a leader in Emergency filter systems since 1828 and there has never been side-effects associated with using these filters. It will efficiently filter out cholera and other pathogens to the highest degree and provide safe drinking water for your members in Africa. They are supplied to Relief Organizations across the globe, ie, the Red Cross and Unicef, as well as, militaries in operation.  We would be happy to provide a 30% discount off these systems if purchased in bulk quantities.  International shipping, if that's the initial shipping destination, can become quite expensive but we would be happy to provide a quotation or refer to you the appropriate department.
 Please let us know which filters you are interested in along with the quantities you see and we can provide a Quotation for you to consider. Please, also, inform us as to where they will be shipping to.
Thank you for your prompt reply! I appreciate your feedback and information. I am very interested in your system and I talked to our directors here and they would like to look at all the options before ordering.
 I am wondering if I could order one system for myself to try and use as a "test model" over here? Would the 30% discount still apply, or is that only for bulk orders? 
We do have a shipping and receiving center NC that we use and they ship things over here in a container. That way the shipping costs are much more affordable. :)

 What gravity filter would you like to test-pilot. The beauty of the Doulton system is that is has been produced for over 180 years and is quite established as far as its' performance is concerned, in Europe more so than U.S. That being said, I understand your need for testing before purchasing in a bulk quantity. We would be happy to provide a 15% discount off a single unit for you to try in your application. Please let us know which filter you are most interested in GSS2 or LP5
and we would be happy to send you a formal quotation.

I want to use non-plastic, compression fittings with under sink water filter

Do you make a residential or commercial drinking water filtration system which has compression fittings or threaded screw connections. I do not want to use plastic tubes and push type connections. I want to use copper tubing.
 We offer a stainless steel water filter system as an inline filter, 3/4" female NPT connections, 1.3 gallons per minute. You may connect to it by using copper tubing and compression fittings. It does not include faucet or installation kit. Please see IFS10-UC

Local source for Doulton filters?

is there a source in the los angeles area for doulton filters? i have at present an everpure undersink system, but am interesting in changing to doulton.
 We do not know of any dealers in the L.A. area but we ship direct all over the U.S. and Internationally. Please view to shop or gather information and let us know if you have any further questions

How to Change Filter

I bought a house that has the water filter. I have extra filters but don't know how to change it. Where can I find instructions on your website? I have the Doulton Ceramic Water Filter Candle - 2" X 9 3/4" Open end ceramic filter.
 The Open End filters fit any Standard Filter Housing and we do not have instructions for those units. However, just make sure you shut-off the water to the filter, have a bucket under the filter because it will be full of water, and unscrew the filter housing.
Then, you can remove the cartridge and insert the new one (with the open end facing up). Turn the water back on and inspect for leaks.
Flush water (run to waste) through the system for 10 minutes and then let it sit for 12-14 hrs. Flush an additional 5 gallons the following day and then the filters are fully primed and ready for use.

Need proper thread nuts for gravity candles

I have a set of 4 Doulton gravity fed water filter candles (10 inch) with 1/4" threads and I need the nuts to go with them. I cannot find any that fit the threads. Can you help me?
 The candles we just sent you have the 1/4" thread and we have the nuts available for those filters. You can find them (ACC-GW) .on Accessories page.

Portable fluoride filters?

Does GSS-Mini-A Personal Emergency Gravity (drip) Water Filter take out fluoride. If not can I add another portable filter to it? What other filters do you recommend for traveling to south east Asia and S America?
 The GSS-Mini filters do not have fluoride removal capability.
Do they add fluoride to the water in SE Asia and S America?
Our larger portable filters can be taken to those locations and you can add the 2"x4" Specialty fluoride filters to the GSS2 systems (all located on the following link, including "add-on" fluoride filters)

UV light with ceramic filter

I have been purchasing for years now your Imperial Supersterasyl filters. We have purchased a couple of your stainless steel british berkefeld over the years as well.
 We have lived in remote Indonesia and now travel back there each year. We typically purchase many of your candles. 
I am interested in becoming a distributor but also curious if you have any uv lights for removing virus before and or after the drip systems?
 We are not offering Distributorships but we do provide significant discounts (25-34% off List Price) for bulk purchases.
Doulton does not sell UV lights but it is always good to use a ceramic filter prior to the UV application. UVs do not work efficiently on turbid water or water which doesn't provide enough contact time with the light.

Wing nut and gasket replacement for gravity filters

Is there a part number and price for replacement wing nut and gasket for the 7" or 10" candle filter?
 It's the ACC-GG Gravity Candle Gasket and ACC-GW Gravity Candle Wing-nut. Both of the items are found on the following accessories page :

Home filters that remove fluoride as well as chlorine

I found your listing in some "Green" Magazine and would like to learn more about your website offering.  Do you have any home filters that remove fluoride as well as chlorine from the water?
 Yes, the Regent II filter located on the following link will remove the chlorine, chemicals, heavy-metals, fluoride, micro-organisms, suspended solids and more:

Gravity filter spigot

I bought from you a Gravity Water Filter GSS2 . Now I need to replace the spigot (ACC GSP Gravity filter spigot with 2 washers) and I need to know if you can send it to Portugal; if so, what are the procedures?
This part can be found and purchased from the following link with the understanding that you will incur an additional international shipping cost of about $ 22.00 for International rates to Portugal.

HCP-UC replacement element

I have HCP-UC filter. I am interested in replacement  element Doulton ULTRACARB. Please could you let me know if you have and the Price plus SH.
CN-UC Ultracarb candle is the correct replacement for the HCP-UC and can be found and purchased on the following link for $59.00 plus flat SH&H $5.99. Free shipping provided for customers who purchased system from

Puro Water Filter replacements

I am the proud owner of a ceramic (leadless glaze)  "Purro Water Filter" by Royal Doulton, England. It belonged to my Mother who would be 104 if she were alive and I brought it with me from Africa when we moved to Portugal.
 Is it possible that cartridges (candles) are still manufactured for my filter? It is 47cm high and carries two candles, one of which  is marked "Doulton-super Sterasyl" and has what I call a bakerlite fitting and is 22cm long from top to bottom (including fitting). The other candle is longer and has a metal fitting marked Katadyn A G Wallisellen Zurich.
 I would be interested in ordering two new candles and would be grateful if you could let me know details.
The filter you would need for the Puro Water Filter would be two of the CN-SS 10" Super Sterasyl (L) located on the following link for $ 38.65 ea.:

 Hello- thank you for your prompt reply. With regard to the CN-SS 10" Super Sterasyl(L) filter you indicate, I see that it is recommended that 3 ilters are put into use and my filter only takes 2. Is is this a problem?  Also, what is the difference between the abovementioned filter and your Sterasyl CN-S 2"x10" Katadyn Ceradyn drip filter that sells for $68.50? Does the latter give better performance? i.e. why is it more nearly double the price?
The CN-SS 10" SuperSterasyl ceramic candle only requires 3 filters if you're using it in a Katadyn drip filter (which you are not). You can use just 2 if need be and it will work the same. The CN-S, as opposed to the CN-SS 2x10 does not contain any activated carbon for chlorine or chemical removal but the ceramic shell on both candles are identical as well as ability to filter out particles and sub-micron contaminants, ie. bacteria. The reason the CN-S is more pricey even without more ability is because it does not require replacement every 6 months or 1 yr. It is simply cleanable and reusable for several years.

 Hello there- sorry to keep coming back but I need to be sure! You tell me that the reason why your CN-S is more pricey is because it does not require frequent replacement (which for me is very attractive) but then you give me to understand that it "does not contain activated carbon for chlorine or chemical removal" which is surely a disadvantage? 
Perhaps I should let you know that I use my filter to ensure pure drinking water for my very small household and  that I live in a rural area completely free of any industrial activity and that the water I get from my tap comes from an underground spring. But I would like to be sure that my filter acts against such things as herbicides,pesticides and other nasties, and  know that "they" are about to start employing chlorine in our water installations.
Then you need a filter which contains carbon inside of it, like the SuperSterasyl.

Flouride/heavy metal Reduction Element CN-B2

I am wondering what the fluoride reduction capacity of the Fluoride/heavy metal reduction element is?
The capacity of the CN-B2 candle is 400-600 gallons (6 months for 4  person household).

Filters for chlorine and fluoride

I am inquiring about your Dual Countertop water filters. I have been researching filters for quite some time and have been looking for something that filters chlorine and fluoride among other hings. I currently have city water but have been buying jugs of water due to the taste. I've looked at Nikken, I've looked at the Berkey, and many other filters. While reading the multitude of reviews your company was recommended as one of the leading in water filters. I'm skeptical about the Berkey and quite frankly don't have the space, a countertop filter would better suit my needs I think. I'm just wondering about the warranty. It says for registered customers it's covered for 3 years. Does that mean that as long as I register the product, then it is covered? Do I have to purchase it through you to be a registered customer?
 To become a registered customer and to receive the three year warranty provided by us, you must purchase the unit directly from At that point, you will have become a registered customer. No need to do anything else.

5in. Imperial SuperSterasyl candles with ATC.

We purchased one of your Aquacrock water chillers some years back. We noticed that our last shipment of replacement candles are about half an inch Shorter than the prior versions of your 6" Imperial SuperSterasyl candles. Is there any reason for this, and will this necessarily affect the performance or durability of their filtering if they're now Shorter than the prior versions?
 The ceramic filters for the AquaCrock used to be 6 in. This was the case up until about 2007 when the manufacturer designed it as a 5 in. replacement candle element which has Lead Reduction capability. Each of these ceramics have a 500 gallon capacity (1,500 gallons when using three).

Imperial SuperSterasyl Ceramic Canldle

Can you  tell me the advantages to purchasing the Imperial SuperSterasyl Ceramic Canldle rather than the SuperSterasyl Canldle?
 The Imperial filters give you higher flow/drip rates and larger operating capacities than the standard size filters. Please review the links and specs. of the two differing units: 2"X7" SuperSterasyl Canldle
and IMPERIAL Supersterasyl

Ceramic Water Filters for hiking and camping

I was looking at the Ceramic Water Filter Candles for portable systems. The question(s) came up:

 How many gallons will the filter provide before it goes bad for the 7" Supersterasyl and 10"?
 Since there is the 7" and the 10" Supersterasyl candle filter, will this change many gallons each one will provide? If more then one candle is added to the buckets will it increase the amount of gallons before going bad? 
Are the candles re-useable and if so how long?
Will the thickness of the filter change the difference of the water provided? Is there a re-useable candle?
I'm asking these question(s) because our family we go out hiking and camping for long period(s) of time and we would love to find something that can fit our lifestyle, we really don't want to end our trip short because of lack of drinking water.
The CN-SS 2"x7" Supersterasyl filter candle has a 535 gallon capacity, whilst the 2"x10" ceramic candle has a 750 gallon capacity rating. It make it easier to use the same size candles for determining the replacement frequency. Essentially, however, you can get about 1,285 gallons of filtered water before you need filter replacement. The more filters you use within the system, your move overall capacity, as well as, production (drip-rate) you will receive achieve.
All of our ceramics, including the ones mentioned above and below, use what's called a Sterasyl shell (membrane). We sell a Sterasyl filter which does not contain activated carbon inside to reduce chemicals, taste and odor. The Sterasyl is simply used to remove suspended solids and micro-organisms from the untreated water. It is because it does not contain any GAC inside, that these filters can be cleaned over 60 times and not need to be replaced for several years. This model is CN-S, and is located on the following link with Doulton other gravity filter candles.

Diverter Valve Replacement for Doulton Countertop filter series

I need to replace my "Diverter Valve" for my Countertop water filter, how can i get one?
 Please see our ACC-DIV-CP diverter valve replacement assembly for $ 25.00 on the following link:
Replacing Diverter Valve Kit on Doulton Countertop Filters Instructions.

How Do I Replace Filters??

 I have a 3 cylinder Doulton unit under my sink. I'm at a loss how to get the cartridges out. The water stream from the faucet is nearly just a trickle now and I really need the filters changed. I  have the replacement filters, but just cannot figure out how to get the plastic sleeves undone. I didn't get any instructions when my plumber installed it and he came over about 8 months ago and took the filters out, rinsed them and that did the trick (the unit was only in about 12 months).

I got as far as the top off, took out 8 screws, a plastic piece came off the three cylinders and then I see these cylinders have a rubber seal holding them into the unit. So, I just put it all back together and now I'm really frustrated because I just don't know what to do. My plumber is out of commission so I can't get him to help. Can you?? Thank you for your assistance.
Hopefully following these instructions will help you:

1. Shut-off the water to the filter. Open the filter faucet up to  remove back pressure built-up. Wait 10 minutes.
  2. Unscrew the filter housings (turn left (clockwise direction if underink) There should be no reason to remove any screws. The screws are only meant to mount the filters to the bracket. The filter housings are the white canisters that have the cartridges inside. These are simply unscrewed so you have access to your cartridges.
 3. Unscrew the filter cartridges and replace with new ones or just clean the ceramic candle ( labeled Ultracarb).
 4. Put everything back together and turn shut-off valve back on.
  Inspect for leaks.
  Here is a link for ceramic filter cleaning instructions:
Thank you for providing these instructions! It worked! The problem was that the plumber that installed the unit had the cylinders screwed in so tight I could not budge them. I was able to get someone to look at the unit this past wkend, he was able to get the cylinders detached, I was able to flush the filters and now the unit is working just fine!
 I love this water filtration system!!! My water is horrible and even with a water softener, I won't drink it. However, with the Doulton filters, I can drink the water! THANK YOU for a terrific product!!
We are so happy we were able to provide some assistance and the issue is now resolved.
Please remember to hand-tighten only. They do not need to be screwed on so tight! Please let us know if and when you need replacement filters and we'll be sure to ship them out right away.

Filtering Hot water

Just wondering if hot water affect the performance of your water filter??
Why I ask? Seems that after I use your product, perhaps after filtering hot water, I realize that there is a built up of white calcium deposits stuck to the rims of the cylinder of my water boiler. Perhaps is the calcium on your filter (large amounts) is transferred to my water boiler???

These filters are for cold water use only and water entering the filters should not exceed 99 degree. There is no calcium in our filters, nor will the filters remove calcium. This is most likely coming from your hot water heater because hot water precipitates calcium faster.

RV water softener

I have a new 2010 Everest I would like to find a water softener/ purifier system for. When we are traveling, 6-10 months/ year, we miss the soft water we have at home. We very seldom boon dock so we're not worried about using the holding tank. When we do I can fill through outside shower or maybe a diversion valve. The unit came with a drinking water filtration but we miss pure water showers and so on. there is plenty of room behind the docking panel for a medium sized unit 2'x3'x2' tall. Please give me any recommendations with prices if you can.
I can install with a good set of directions or have installed if needed for warranty
 Consider our Salt-Free Water conditioner. It doesn't soften the water but conditions it to where it does not scale deposit on and in your plumbing system. At the same time, it feels like soften water ;except without the slippery, slimy, feel. Please see our NoScale system designed for boats and RVs:

Filtration system in time of emergency

I want to purchase a ceramic candle (or similar) filtration system that I can use in time of emergency. I do not want something that hooks up to a current plumbing system. I want something that I can use with river water, for example, and turn it into drinking water. What do you recommend.
 For personal use, consider the Personal Emergency Gravity (drip) Water Filter For household/family use, consider  the GSS2
 These systems will all provide you with premium quality water from any water source (except for sea water). The only main differences is the container size, as well as, the total output (per hour, per day, total capacity).

Total Dissolved Solids (TDS)

I've a Doulton Ultracarb counter top filters - 2 candles.  I did a TDS test on a cup of filter water and it has TDS value of 260. This result is much higher compared to a bottle of Dasani which is only 50. I wonder what the average TDS level is for the Doulton filtered water? How can I reduce TDS level in my Douton filtered water?
 Because TDS consists mostly of dissolved minerals and salts in the water, you will not see a drastic reduction in TDS, nor should it be an accurate measure of water quality. Our filters leave essential minerals in tact, while technologies such as Reverse Osmosis (Dasani) and Distillation strip them from the water making a very acidic/aggressive water.

Rainwater from the roof

I recently purchased the GSS2-IMP for my part-time home in Hawaii. It is safely stashed away against the possibility that the piped water supply is cut off (hurricane, power outage, etc.).
My plan is to catch rainwater from my roof which is the usual asphalt shingle construction (appx two years old).
 Please confirm that the unit will successfully and safely filter roof-caught rainwater including removing whatever petroleum products may leach out of the shingles and become a part of the runoff.
The GSS2-IMP will be extremely efficient at making the water potable and free of micro-organisms, particulates, and carbon based chemicals, such as petroleum products. If you want to filter further, consider two  CN-B2 2"x4" heavy-metal reduction elements to add on to your system. They can be purchased at the following link for $ 24.00 ea

Problems with aquacrock

We bought 2 aquacrocks a few weeks ago. One went to my husband's office and the other is in our house. The house one is only  producing about a quart of filtered water in 6 hours. What is wrong?
I'm sorry to hear you are experiencing problems with your AquaCrock filter system. With gravity filters, such as these, it can take 3-4 days for the ceramic filters to condition themselves to the water
supply. During this time, the filter production rate can be brutally slow. After 72 hours of the filters being in contact with your water, the flow-rate should drastically increase and even reach above 1/2
gallon (2 quarts) per hour. How long has these filters been installed and have been filtering the water? If the unit is not producing water fast enough after several days in operation, then I would advise you
to remove the 3 candles from the system and let them completely dry out. After about 24 hrs and dry, reinstall the candles and run 1 batch of water through the unit and discard it. Then, fill up the top
reservoir full of water once again and see how long it takes to filter the water. At that time, you can consume the filtered water.
If the problem still persists after this conditioning process, please let us know right away and we'll take the next step.

Under counter Water Filters

Can you tell me what the difference is between your under counter water filter and a 5 stage reverse osmosis system? I am looking to remove fluoride from my water.Can you also send me a list of the specific contaminants/chemicals that your system removes and the percentage of removal?
Also, does your system require a storage tank? If not, why not?
This is a good link which educates you on the difference in water treatment technologies:
For fluoride removal you will need a Doulton 200 series under counter filter, IP200UC+. It does not require a storage tank because (unlike R.O.) it produces water on demand at a steady 1/2 gallon per minute. R.O. requires storage tank because it wastes 3-4 gallons for every gallon of water it produces. The 200 series filter will contain 2 cartridges within. The specs for these cartridges are on the links: (Ultracarb ceramic candle) and (fluoride specific candle).

3-4 Person Family Filter System

Please recommend which model number is the best to fit a family of 3-4 people for cooking and drinking water. What is the Ph value for the normal people to use. What is your lead time to ship out the product after you receive an order? Is the filer easy to install?
 I'll recommend one of our most versatile and sought after undersink filters. It is the dual cartridge system located here: ; Our filters will not adjust or effect the pH of your water. Typical city water is around 7.5 pH and our filters will not mess with that.
 Lead-time is 2-5 business days after order is placed and will depend on your location. The filters come with a DIY installation kit for any handy person to install.

Enhanced Filter Systems

Thanks for your prompt reply. Great service! I'm wondering if there is any upscale models you'll recommend than IP200UC?
I'm not sure what you mean by "upscale" but we do have the same version in a stainless steel model. Please see: We also have a triple canister system with added filtration capability, and a High-Flow/High Capacity system, here:
 Any of these items would be a great choice for you and your family.

Nitrate Filters For Gravity Filters

gss2- i want nitrate protection do i configure the gss2?
do i run water through supersterasyl candles and then replace supersterasyl candles with nitrate candles and run it through again?
 The 2"x4" Nitrate filters connect to the SuperSterasyl filters at the UNDERSIDE of the upper chamber. We provide it with a coupler that connects the two kinds of candles together so that the water goes through BOTH filter elements. Please see

RIO 2000 and Clay Sediments

I am a homeowner with a water well. For years, when rainfall exceeds 1" in 24 hours, the water turns brown for 24 to 48 hours. I'm pretty sure it's fine clay sediment because it precipitates over a period of months to a thin mud-like residue in my toilet tanks. When I bought the house, the well was equipped with a UV sterilizer and sediment prefilter. I use 5u string-wound cartridges. I want a filter that will remove the brown color. Even a 1u PUR faucet filter does not completely remove it, suggesting that the smallest particles are sub-micron, but I don't know how to be sure. What I have read ranges from vague to misleading. Any Ideas?
 You could use the RIO 2000 ceramic micro filter, however, during these rainy and run-off periods, the colloidal clay you have in your water may clog this tight filter element. It filters particles down to 0.05 micron in size so it will certainly filter it out. However, there's no way to determine how often the filter gets clogged and requires cleaning. I would first try to use a 1 micron sediment depth filter, like the one we have here:
 If that doesn't work, then you could certainly consider the RIO 2000 filter system but please be aware it may require daily maintenance because this clay matter can pass through a pre-filter.

Water filter running very slow

Our water filter is running extremely slow.   Do we need to replace the filter?
 The filter should be replaced ever 6 months for a household of 4 people (1 yr. for 2 personl HH). However, during that time, you may see a considerable decrease in water flow-rate because the ceramic filter candle is becoming clogged. When this happens, you can clean the filter to restore the flow-rate to its' typical 1/2 gal. per minute. Please see cleaning instructions here:


I am looking at two of the water filters trying to compare &  decide which one will remove more chemical pollutants from groundwater. I live in Norfolk, VA, and am told that the main difficulty in using well water here in an emergency is not so much filtration of bacteria & such,which is pretty straightforward, but the chemicals in the water table.
 Of course after I purchase a unit, I am still going to have the filtered water tested at a lab for VOC's and anything else that can be tested before I commit to drinking it, but m intent is to obtain safe filtration of local groundwater for use after a major hurricane. here in Tidewater Virginia, local watersources have already been made undrinkable for an extended period from contamination after a mere category II hurricane (not severe), and no one seems alarmed by this.

 GSS2 Series - Portable gravity filter 10 GPD (40 LPD) two candle system Offers some add-ons or upgrades. One can apparently upgrade the original CN-SS supersterasyl filter to the Imperial Supersterasyl filter  CN-SSI. There are several more possible upgrades listed for this filter system.
 CN-B2 2x4 Fluoride/heavy metal reduction element for gravity drip water filters 2"x4"
CN-A3 2x4 Nitrate reduction element for gravity drip water filters 2"x4"
CN-M1 2x4 MTBE reduction element for gravity drip water filters 2"x4"
CN-A5 2x4 Arsenic reduction element for gravity drip water filters 2"x4"
Do I as the user have to decide which of these2x4 filters I want to use, or can I use all 4 of them in addition to the Imperial Supersterasyl filter upgrade?
May main concern is removing chemical pollutants.
These portable filters are the perfect choice for you to use when there is not a reliable water source or for any periods of emergency. If there's bacterial and chlorine resistant Cysts in the water, it will filter them out. These are all extremely good at removing VOCs from the water. The specialty elements you have listed should only be used if you are using the filter daily for drinking water. You should only use one kind of "add-on" filter with these systems. For example, for city water, typically choose the CN-B2 2x4. If you use a mix of filters, you are essentially only filtering half the water for that specific contaminant.
All three options will provide virtually chemical and microbiological free water. You just have to choose which set-up you prefer and best suites your tastes.

Ultracarb Filters with Instant-Hot Systems

Can I combine the Ultracarb filter with a hot water dispenser?
Sure you can. We sell filters containing the Ultracarb filter and we sell hot/cold systems that utilize the Ultracarb. Please see our Instant Hot and Instant Hot/Cold Filter systems on the following links:

Differences in GSS2 and GSS2 IMP

 I do not know if my gravity filter is a GSS2 or a GSS2 IMP so am unsure what replacement filters to order. Are the filters interchangeable? Can you use the Super Sterasyl filter candle in either model?
The filters are interchangeable. The IMP filters have a CN-SSI  2 3/4" diameter compared to a CN-SS  2" diameter. That's the only difference. The difference in price represents the higher flow and higher capacities associated with the Imperial elements.

What Order are the Filters Installed?

The tap water should go to which one first---the ceramic one or the one with metal deduction (the one you are shipping to us for replacement).
The B-2 metal reduction filter (or any specialty element filter) is the one which is installed in the FIRST filter housing. The ceramic filter element is almost ALWAYS installed as the last stage of filtration.

Differences in GSS-Mini-A and GSS-Mini-7

I am interested in your GSS-Mini-7 water filters for travel.
2 questions:1. What's the difference between the Gss-mini-7 and gss-mini-A?
2. Do i simply pour water into the container and then re-pour the filtered water out to drink?
 To use the filter you simply pour water into the upper chamber and then the filtered water drips into the lower chamber. It's a surgical-grade stainless steel container which you can drink from or pour into another container to consume from.
 I have provided the following link which shows a table that provides the most clarity as to the difference of the two models. Please review:

Do the Specialty Element Filters Work with the GSS-Min

Do you make any flouide/arsenic/MTBE filters to fit the personal GSS-Mini which takes a Doulton 2x7 Supersterasyl candle?
Unfortunately, because of the size constraints, those specialty element filters will not fit a personal traveler filter.


Is your company related to the "Berkey" company selling seemingly identical filters?

Chlorine Water Filtration

My wife would like a water filter for chlorine removal and being the skeptic I have serious doubts about being able to simply filter chlorine from our water. Can you provide me with the product you have that filters chlorine and are they ANSI/NSF 42 approved? 

Actually, chlorine is one of the more basic, common and simplest contaminants that can be removed from the water. Any filter that contains activated carbon will be fully effective against not only chlorine, but VOCs, and disinfectant by-products (known carcinogens). Our ceramic filters have an activated carbon core and they are NSF 42 approved.

Fluoride Reduction Water Filter

I am trying to decide on purchasing your countertop dual candle water filter especially for it's fluoride removal option. I am trying to ascertain how much fluoride it removes and if that is only the man-made fluoride or also naturally occurring fluoride as well. Another competing brand with a similar dual candle filter system, claims to remove only man-made fluoride and that it would take thousands of dollars more to get a system that removes both man-made and naturally occurring. So I am wondering if that is the case for your system as well.
The  filter will remove fluoride, both man-made and natural, to a very high degree. There are however, variable which effect how much fluoride is removed, such as; bicarbonates, ph, etc. However, in most cases, you will get non-detectable levels of fluoride for up to 400-600 gallons.
