User Q & A

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

How often does this remineralizer filter need to be replaced? Thank you! 

Asked by: Raspers
The remineralizer should be replaced once a year along with the membrane. To receive a 15% discount on this filter, give us a call at 866.662.6885 and we can get it added on to your Water For Life account. https://www.aquasana.com/water-for-life 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.

What are the performance specifications? What exactly is being added to the drinking water, and in what quantities? What is the "optimal mineralization" level mentioned in product description? I could not find any details -- kindly post. Thank you.

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.
