The water purification filter from the manufacturer Aquaphor B300, I purchased back in my student days. I simply could not drink water in a rented apartment from under the tap, its quality left much to be desired, therefore, without hesitation I decided that the filter was the first necessary thing for me and my health.
I’ll warn you right away. This filter is not suitable for every crane, therefore, ideally consult your sales assistant if you can screw this filter onto a crane.
The cartridge lasted for about a year, so often you do not have to change the consumables. The cost of the filter is not expensive, you can buy it in many stores, the model is common.
Of course, I will recommend it, the filter is convenient and easy to use, it is inexpensive and consumables do not change so often, I had a cartridge for a year (but I lived alone in an apartment, more people, respectively, and more consumption).
pros
compact, not expensive, good degree of cleaning
Minuses
not a convenient pipe; not every crane can be worn with a ring
