User Q & A

Does this filter make water alkaline? If not, do you have one that does?

Asked by: Ursula
In some cases, yes, but not in all cases. It really depends on how low the pH is before purification. The lower the pH, the more difficult it is to bring it back up to a 7. However, most municipalities have pH levels above a 7 and starting out with low pH is rare.

Hello do you sell a remineralizing product for my undersink filter? It’s a claryum filter with 3 filters, sediment, A, B. 

Asked by: MattJones
Our AQ-5300 system does not need a remineralizer, as it is specifically designed to leave all the healthy minerals in your water. Thank you, Aquasana Customer Support

Is there any reason I can't put this remineralizer cartridge BEFORE the tank instead of after it? 

Asked by: Scot
My guess is you’d m be getting calcium build up in the tank.

replacement filter for factory whirlpool refridgerator

Asked by: gary w.

What minerals are released in the remineralization process, and in what quantities?

Asked by: KMG76

I just purchased the Aquasana remineralizer replacement for my RO3 system and it leaks incessively even with the faucet off. A new one was mailed, but does the same thing. Is there tech support for this issue? The hoses are connected correctly.
