It takes time to evaluate the quality of the filtration. Never used these filters before. While it works fine. There are no foreign smells and tastes. Its pros: Filters. Fairly easy to install. Convenient cartridge change. Cons: The description of the spout in the instructions is not true. I had to put washers and gaskets in terms of general erudition. In the brass branch, which serves for "tie-in", the gasket is too small in diameter (where the union nut is). When tightened, the gasket is recessed into the counterpart and in fact does not work. So the connection is leaking. How did I just not screw it :-) I had to rummage through the bins and find a gasket with a slightly larger diameter.
