Aquasana Replacement Filter Cartridge for Countertop Water Filtration System - Removes Up To 97% of Chlorine & 99% of 77 Contaminants - Filtration for Clean Tasting Water from Kitchen Faucet- AQ-4035

We purchased this filter system 6 or 7 months ago to replace a GE system. We where very happy with the filtration function as it removed both chlorine residue and water off tastes, we were not happy however with the unit's manufacture as it leaked like a sieve necessitating a bucket under the sink . I sent an e mail to the Aquasana company and they immediately sent a new holder and a new set of filters. An easy install and NO LEAKS. I don't know if their quality control has improved- if we got a defective unit originally or whatever, but I am very satisfied with the performance of the replacement unit and the company's quick efforts to correct the problem.

$60 for a filter that will last 6 months, can't beat it! The water clearly tastes better through the Aquasana filter as opposed to straight tap water. never noticed it before, but I can actually smell the chlorine in our tap water when I don't use the filter. My wife, for some reason doesn't use the filtered water, sometimes when she pours me a glass of water I can tell immediately that it's the tap water. The taste and smell are noticeably different. She says I'm crazy, but after drinking the filtered water it has ruined me for tap water. I've been using these filters now for 2 years, have never had any problems with them or with water pressure as I've read on other reviews. When you replace your filters, take a look at the used ones and compare the coloring to the new filters, you'll see how brown the used filters are, if not, maybe it's our local water. :)

We have owned a countertop, aqua water filter for many years. It’s better than drinking city water. I definitely recommend the system to anyone looking to save on a water bill and have better tasting water rather than purchasing it out of the store.

Despite claims that our municipal water supply is world famous for its purity, these filters successfully screen out significant impurities that are visible and I can only imagine it also captures many non-visible impurities as well. These are factory replacements and they do not impede water flow as much as some of the cheaper after market filters which may not filter as well either. These do not alter flavor significantly although it does remove the flavor we associate with flouride and chlorine that is sometimes noticeable without the filters. The factory design can make it a bit cumbersome to replace these but that is due to system design, not these filters specifically. Be sure to install with correct order (blue vs. white) and in the correct orientation to ensure they function correctly as it is easy to install improperly. Observe what you remove and replace in the same manner. The price and delivery via Amazon has been very satisfactory.

The ease of installation makes changing the filter a quick change. I use my Aquasana everyday …. all day.

Excellent product fast delivery

I have had my Aquasana counter-top filter for 1 year 5 months, and it stopped working a month ago. I have two new sets of filters, or about $102 sitting on my counter with the unit, another $68. Aquasana refuses to answer my emails about the defective system. I purchased it Oct., 2016, so it is 1 year and 5 months old. I am very unhappy with such a short use life of the filter. It worked great, but the filters are expensive, and need to be replaced every 5-6 months at $50 each time. My sister has a Berkey filter which she's had for 6-8 years, and still works amazingly. Guess I shouldn't have tried to save money on what I thought was good brand.

We've been using this filter for 15+ years. I'm glad that we found the store in Amazon so we can order replacement filter. It works great and save tons of $ buying water bottles at supermarket.

Estoy muy satisfecho. Yo no puedo juzgar de la calidad analítica del agua, pero los filtros tienen reconocida esta calidad. Lo que puedo juzgar es el sabor y el olor, y puedo decir que quita todos los problemas que tiene el agua de la traida en el lugar donde resido. En Amazon, ha estado a buen precio, pero en este momento está carísimo. He comprado estos filtros a través de varios distribuidores, pues por desgracia el fabricante no vende en España.

use this unit for 2 years and by replacinc the carteiges once a year I have pure waer. Our city water have lot of calcium and chlorine in it. With tis ;no smell no more tar buit-up in humidifier and kettle .I realy like it and recommand it . Easy to install and maintain.

The water quality is super compared to any Brita filter types. The price is good considering: 1) the quality of the water and 2) the filter changing is required once per year (450 gallons of water = 1620 liters = 4.43 liters per day consumed): great ;o) . The entire system is slightly leaking from the bottom, I can live with that.

Very good filter

Overall a great water filtration system .produces good drinking water
