Excellent water quality. I use it directly under the sink in cold water without any drop in pressure. I have been using it for 1.5 years and even when I change it, the pressure has not dropped and the water does not smell. It is very easy to change, with a twist of the valve it comes out and with another twist the new one is installed. I do it myself, of course, without any tools. Perfect for use in a city network.

Very good filter, the water doesn't smell. To last for 1 year on a central faucet (and for dishwashing), put a cheap polypropylene filter before the main filter to catch dirt and odors, and you will be very satisfied!!! Update: I installed the filter on a three-way faucet to have it only for cooking and drinking water, as well as washing fruits and vegetables. It's perfect, worth its money.
