Easy to install! in kitchen and bathware

Fast delivery, better price than the brand website, very easy to install and use. Still have to figure out how to recycle them (it mentions that this is only possible in the US)

Pros

Cons
  • Weight

Makes tap water drinkable

The water in my apartment is so bad that I had to use ice and bottled water for cooking before installing the filtration system. Replacing the cartridges was very easy and hassle-free.

Pros
  • Impact-resistant plastic construction
Cons
  • There are even more interesting options.

Short filter life Suitable for replacement water filters

A plumber installed a filtration system a few years ago. We are happy with the taste of the water, and the filters are relatively easy to change (be sure to turn off the water before changing the filter!

Pros
  • Filter head automatically shuts off water supply when cartridge is removed
Cons
  • Crumpled packaging

Gradual decrease in consumption and efficiency.

In July 2020 I installed a water filter under the sink with a Kohler Duel cartridge. Everything was good. Both filter cartridges replaced in May 2021, but one of them was leaking. I sent them back to Revain for a replacement which I received promptly. But now, after 5 months, the water consumption is about 50% less than when the filters were new. A noticeable chlorine taste also returned. Very disappointed with the short lifespan of the replacement cartridges and the replacement cost has…
