The worst thing about this filter.....and the activated carbon it claims to have.... deception.... few loose particles in the center.... not even up to the top.... I opened the top lid and couldn't believe it

It eliminates odors from old pipes. In the initial use, it requires running plenty of water because pieces of carbon usually escape from the cylinder and reach the water outlet. It may be necessary to unscrew the bottom spout to remove a small piece of carbon from the grate

I have been using it for years, it seems to do the job. On one hand, because the water doesn't smell, and on the other hand, over time, its sponge turns from white to brown-yellow, which means it is holding something. Additionally, the clarity of the water is also noticeable. However, I haven't taken the water for analysis to the state's chemistry lab to see more details. And the price is very good for the job it does.

The friend is good.
I don't know if it really holds many "bad" things, but it definitely holds the smells and you feel the water softer.
