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.

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 Bromate

 I have two of your water filter systems and am very pleased.
My question is does it also filter Bromate out as well??

 Though Bromate is not normally found in water, it can be present in low concentrations when ozone is used as a primary disinfectant. The amount of Bromate converted from Bromine depends on the amount of Bromine in the source water, reaction time, pH, etc. The EPA has set forth guidelines to limit the amount of Bromine from the water, as well as, MCL goals which restrict the amount of Bromate formation levels down to "safe, allowable levels" from long-term exposure.
There is no know 100% reliable way to remove Bromate from water but given favorable conditions, Reverse Osmosis, GAC, and Ion-Exchange have been used and given warrantable further analysis for
 filtration. That being said, at this time, I would recommend a filter system containing 2-3 Activated Carbon filters within it, such as; R.O. systems or a multi-housing filter system like a Doulton 200 series filter unit, http://doultonusa.com/HTML%20pages/ip200UC_plus.htm. I also think a gravity filter would perform well because it offers significant, necessary filter contact time (slow, drip filtration), such as http://doultonusa.com/HTML%20pages/portable_systems.htm. .

DoultonUSA (CUSTOMER FEEDBACK/CUSTOMER SERVICE)

 I just want to thank you for all the help with our new under sink water filtration system. For years we have used a PUR filter that attaches to the faucet. We live in the country and were changing a $19 filter every 2 to 3 weeks. I have ordered for years from Allergy Buyers Club and called them to see what they would recommend. I actually called 2 separate times to talk to 2 separate customer service agents. They both recommended the Doulton. However, they both told me that it is not recommended for someone with a well.
In frustration, I finally called DoultonUSA. Best decision I ever made. First of all they KNOW the products. Second of all they stopped me from buying something that was way more than I needed. Thirdly, the faucet fixture itself was so superior and heavy duty compared to every thing Doulton on Amazon and Allergy Buyers Club. I called several times and the customer service people were so patient and helpful. We got our filter in just a couple of days. The fixture is beautiful. It has no plastic and looks perfect with our existing heavy duty fixtures. When the agent said EVERYTHING you need for installation is in the box. He was correct. The directions were easy and all the parts were top
quality. The actual filter meets NSF 42 and NSF 53 standards. The water is so good. This is going to save us so much money.

I now have called back several times and have just ordered a whole house AquaCera No Scale system. It is German technology. I am excited because it changes the structure of the lime without using salt or an expensive reverse osmosis system. The Europeans are truly way ahead of us in their green solutions. This ceramic medium filter should make our appliances last much longer. I will be glad not to use 3 gallons of white vinegar a week fighting lime build up. I cannot wait to get it in.

Thank you for being a truly customer service oriented company! We will recommend you to all our friends.
