Review on Filter under the sink Geyser Standard for hard water white by Stanislaw Wawrzynowi ᠌

I've been using this filter for a month and a half. The water had a strange taste. After boiling, a lot of plaque remains in the kettle. Before that, I used bottled water and for a year the heating element of the kettle was close to the state of a mirror. And from the water after the filter, the mirror disappeared under a thick layer of plaque. Annoying.
