Whole home water filtration systems

I just purchased your shower filters for our home and looking at your whole home systems.
I recently had a friend tell me about this system they purchased in Nevada.

There system says you are able to drink water at every faucet??
I am looking for your guidance in this because of your years in this industry. Look forward to learning more about your systems and how to set up our home properly.

We have a 3 bath home with 3 people.

The filter you point to is just an ordinary filter similar as ours except I don't know which back-wash controller they use. We can dress our filters with chrome look jacket or other colors as an option. The manufacturer of the KDF55 media which is combination of copper and zinc alloy "claims" many "magical" performance however they cannot substantiate any of them except conversion of chlorine to chlorides. The NSF 61 standard is nothing than the media is OK to be in contact with potable water. For more information on their and other water chemistry hucksters "claims" visit retired chemistry professor Brown page on the following link:

Your friend filter is fine as it have carbon in it. As far softening we nor KDF Fluid mfg. have not a single proof of softening hard water.
I'm sure you'll have more questions so feel free to do so.

Also you can find some info on Steve Lower "BunkHouse" product cross-reference page, which has an entry for this product and a link to the appropriate explanatory section of the AquaScams site.

I am looking at getting the following from you whole house ACBTC- CA10 carbon filter
with the coconut shell carbon. I have a water softner on the home now for hard water. Would I leave the softner in place and run this filter before the softner?
I would also get the IP300PSCB-2 for our drinking water.

Question about water softners. The salt comes the reserve salt tank to clean the media in the unit? Do you get salt in your water?
If I remember right you are on city chlorinated water. Can you tell me how old is your softener. The reason for this question is that your softener resin may be damaged as chlorine can destroy resin in very few years but that's not a big deal as you can replace the resin, not expensive. If you tell me the diameter and height of the tank (not including the controller) I can tell you how much resin you need. Should you need to change the resin we can help you over the phone on how to change it, it's very simple.
Our best resin cost $104.00 per cubic foot.
On chlorinated water carbon filter is always installed before softener.

Salt is used to regenerate the the resin beads therefore softener does add sodium to the water and the amount of sodium is based on hardness of your water (see table bellow).
Please concider our NEW NO SALT softeners up to 25 gpg/425 mg/L hardness and special blend granular activated carbon (GAC) filtration systems for high reduction of chlorine, chloramines, THM's, PAH's, VOC's and industrial chemicals for hard, city water.

Initial Hardness Sodium Added

1.0 grains per gallon 7.5 milligrams/quart

5.0 grains per gallon 37.5 milligrams/quart

10.0 grains per gallon 75.0 milligrams/quart

20.0 grains per gallon 150.0 milligrams/quart

40.0 grains per gallon 300.0 milligrams/quart

As a comparison: One slice of white bread has 161 milligrams of sodium; 3/4 cup of canned baked beans = 1130 milligrams; 1 tablespoon of catsup = 204 milligrams; 1 medium frankfurter = 610 milligrams; and 1 cup of whole milk = 127 milligrams. However, if you are under low sodium intake advisory you can use potassium chloride for regeneration instead of salt and this will cut down the sodium in your water by 99%.

If you intend to buy the whole house filter you will not need the shower filters which you can return them if they are not used.
