Awesome filter. Noticeable difference in taste after installing. I'm in Arizona and we have the worst tasting water known to mankind. The water is bearable after installing this filter. It's not RO quality but I don't have the ability to connect my fridge to my RO system so this was the next best thing. I like the fact that this filter should last 2 years and costs the same as 1 factory refrigerator filter would have. It produces better tasting water then the factory filter in my fridge did even though they are the same manufacture. My only complaint is the size. My refrigerator now protrudes several inches further away from the wall. Given the location of my fridge, the gap is very visible. I quickly got use to it. This is the only reason I gave it 4 stars... definitely 5 stars otherwise.
Go this for under the kitchen sink to replace the old dual cartridge 'Omni' filter I had, which was such a Pain to unscrew the housings and change filters. With this one, the filter and housing are all on piece. Just shove it in and give it a quarter turn to lock it in. No special wrench and no water spilling all over. So simple!
And So inexpensive too. The cartridges last 2 years and are $35 here on Amazon, but I actually found replacements on a wholesale filter website for only $25. They even make a 3 year cartridge for just 10 bucks more. Takes up way less space than my old filter and the water flow is great. I can't believe it took so long for someone to come up with this design, but Thank You!!!
