The NU Aqua inline Alkaline filter is the perfect addition to any reverse osmosis system. This filter features ¼” quick connect fittings so it can be easily attached between the system and faucet which will instantly provide naturally mineralized ph positive water.

Excellent service and water

Excellent RO under the counter system and superb service.

Good minerals added to the water.

The Lubbock Texas city water tastes terrible because half of it comes from 2 lakes. The purifying system they use adds ammonia to the water making chloramines which makes it only good for flushing toilets. The Hydrologic ChloraShield Catalytic carbon filter HL22020, I installed makes the water taste totally great, like Walmart spring water we have had to buy the last year since we built a house here. This filter adds some good minerals to the water.

Under sink RO system

Great system and economical to maintain. Clamp on filter housings would make filter replacement easier but would probably be more upfront costs. I modified the installation to have a slide out and just makes things so much easier. High recommendation!!

Best under sink filter yet

We had it installed and we are very happy with the filter.My daughter noticed immediately the difference in taste because we also installed the alkaline filter which we didn’t have before.But we are happy and I subscribed for every 6 months filter delivery.

Excellent product!

I was buying high alkaline water from a place in town but a friend told me about this product. Ordered and installed and tested and getting consistent 9.3-9.8 alkaline reading and really increased the taste of my RO water. Really happy with it!
