I have been using this water filter for many years. The taste of the water has improved significantly to the point where if I drink chlorinated water, the difference is immediately noticeable. Additionally, in cases of water interruption, when it returns, the water from the regular faucet is brown from the mud, while at the same time, the water from the filter is crystal clear. Removing the old filter (after a year) and installing the new one is a simple process: twist and unlock, twist and lock. It is also convenient that it is installed under the sink and is not related to the cumbersome systems that take up space like the ones we see on TV. Of course, it requires a suitable faucet to be installed, I have the very good eos triflow from Franke. I have two negatives to mention: a) the price, which increases every year, and b) the limited availability. If you try to buy it at the end of the year, you can't find it anywhere. It is sold out in most stores, while the company cites inventory issues and states that it will be available after 1-1.5 months.
