In principle, not expensive, if you calculate how much benefit it brings. I paid a little less than 8 thousand for it. But now it’s safe for the washing machine and there is no scale in the kettle (full protection against scale in addition to deep water purification). The filter not only cleans the water, but also softens it. In short, nothing dangerous to health remains in the water, if in simple words, I don’t know how to say it smartly (the seller told me a lot of things in the store). But visually, yes, I see a difference in transparency. Installation is free, but the master was very friendly (usually freebies bark at people), explained everything well and said to call for any problem.
