Tools and Hardware Reviews of Aquasana undercounter water filter system

Customer Review: I could not be more pleased
Summary: 5 Stars

I have owned this system for over 1 year and I am using my third set of filters.

I have found replacing the filters much easier than other water systems I have used (although replacing them does require unscrewing two covers, so it may not be absolutely the easiest system available).

I have had NO problems with the system. I have NOT seen any of the leaking or slow water flow or any other problems that others have mentioned. My latest set of replacement filters came with a tube of FDA approved O-ring sealant, so that addition to the filter replacement process may have been made to address some of the kinds of problems others seem to have experienced.

The water is free of unpleasant smells or taste (unlike the hard, chlorine-rich, algae flavored tap water that it filters). The difference is remarkable. I had to get used to some minerals being left in the water, since the AQ4000 leaves minerals in and my previous drinking water sources (a Premium reverse osmosis system and purchased RO water) took all the minerals out, as reverse osmosis systems are designed to do.

The AQ4000 is not a reverse osmosis system but it does produce pure and tasty water at about nine cents per gallon, based on recommended filter changes.

I do wish that I got the upgraded spigot with the twist valve instead of the flapper type valve, but that is a matter of preference.

Customer Review: Aquasana 4000 Undercounter Reverse Osmosis Water Filter System
Summary: 5 Stars

Two seperate boxes. Easy to install. Low presure lines and fittings seem a bit flimsy but the lines haven't leaked and the system works fine. I live in a beach town and like most beach towns, our tap water is horrible, full of chlorine and who knows what else. The filtered water tastes better that any bottled water I've used. I hope this system lasts a long time. I highly recommend this system for drinking water which is reported to be less than 9 cents per gallon. Purchased from BestFilters for a low price and they seemed like a good company to deal with.

Customer Review: Works Well!
Summary: 5 Stars

I own Aquasana countertop filter that bought 7 months ago. No problems, nice clean better tasting water. Water flow is 1/2 gallons per minute. Acceptable because good filtration requires slow water flow.

Just spoke with representative of Aquasana regarding problems with housing units. They acknowledged the problem existing for unites manufactured before July 2008. Those older units were designed to handle water pressure of 60-70 PSI, while new design is capable of handling water pressure of up to 100 PSI.

Customer Review: Great system!
Summary: 5 Stars

We absolutely love this unit! We have used this system for a number of years now. A couple of years ago, the threads stripped on the filter housing, and the Aquasana replaced the entire filter housing. We've never had any leaks (we had it professionally installed), no problems with pressure...just pure, wonderful water!

Customer Review: Aquasana AQ-4000 Water Filter
Summary: 5 Stars

Excellent water filter, highly recommended. Easy to install. We are using it of 6 months now and love it. You can taste the difference, water after filtering is a bit sweeter and much clearer. Also great for an aquarium.
