Aquasana = satisfied customer > 10 years
Did you know which over-the-sink water filter model was preferred by non-profits handing out filters to residents in Flint, Michigan? That's right, Aquasana. That's because their established quality and unmatched customer service is famous in the consumer water treatment world. We've been satisfied customers of Aquasana for over 10 years and have used several of their models over the years and across different houses we've lived in.We just updated our under the sink dual-filter drinking system with a reservoir tank to help boost the pressure coming out of the filtered water spout. Added this mineral filter to the chain, after the reservoir to add in some of the flavor lost by the filter and the water softener. The first day was a bit overboard but ever since it's been beautiful. Like drinking the well water from a mountain cabin in Switzerland

Improves RO water taste
I installed this cartridge with another brand RO system with great results. The water has a better taste and it results in more flavor in coffee. It has 3/8" sharkbite fittings installed so I bought adapters at Home Depot to connect it to the 1/4" tubing my system uses, it doesn't seem to have affected system pressure or flow at all.Make sure to run a couple quarts through before drinking, or you'll have a few glasses of very strange tasting water.

id'e recommend it to Anyone with an RO unit
Really makes a huge difference in the taste and health benefits of RO water. Without it, RO water tastes odd, sharp, almost lacking something. This helps so much, we live our RO water now, id'e recommend it to Anyone with an RO unit.
