User Q & A

I prefer to use the RO System without the remineralizer. Can the system be set up such that the remineralizer is not attached.

Can I use this remineralizer in conjunction with my Berkey filter? My water source is almost devoid of calcium and magnesium. But I am off-grid and have no electricity, so I would have to depend on gravity to pull the water through this remineralizer.

There are no marked inlet and outlet on the remineralizer. Does it matter which way you install it?

Why do I need to add mineral to my water after I just removed everything from it.I am interested in drinking pure H2O and why wouldn't my body be better with out the mineral.I eat well, take vitamin supplement daily, drink only bottled reverse osmosisH2O.

Asked by: I love pure H2O
The reverse osmosis system includes a remineralizer that puts the healthy minerals like calcium, magnesium, and potassium our bodies need back in your filtered water. Just like vitamins, minerals help your body grow, develop, and stay healthy. The body uses minerals to perform many different functions — from building strong bones to transmitting nerve impulses. Some minerals are even used to make hormones or maintain a normal heartbeat.

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
