I use this mounted before the water line goes to the frig and filters it again. I get water from the frig for everything cooking drinking etc.. It tastes great but after a year I recommend replacing because the housing tends to get stagnent and needs a good cleaning. Great product.

Lasted only about 4-6 weeks in a home with 2 adults. When it was working, before the water flow came to a trickle the water was very good quality. Would not purchase again as it does not last. Expected at least 3 months from it. We have a lot of iron in our water.

Comment Reply: Joel, thanks for your comment. Lots of iron should clog these filters, as it tries to remove iron and has a limited capacity for it. When filtering lots of iron with a countertop or under sink system, we recommend filtering through an iron removal cartridge first, which means you need to have a standard 10"x2.5" dual or triple filter system, or purchase a separate 10 inch inline housing for iron filter.

The 6-stage Filter Cartridge works amazing! My mother and I both use this product. It filters our water so good, it taste better than when you buy it bottled at the store. Both my house and my mother’s house are very old. The water piping we have is quite old, and was giving off a metallic taste. After using or water filtered through the cartridge, its taste heavenly! A+++product!
