In terms of price / quality ratio, the Polaris PPA 0401i air washer is a decent option. We have this sink in the kitchen and copes with its work perfectly. Naturally, she could not clean the entire apartment, but she copes with her premises with a bang! Replaceable filters are inexpensive, so that the consumables just do not go broke. On average, buying a set of all the necessary filters (there are three of them) will cost from 100 to 200 rubles. I change the filter every six months.
The first week after the purchase, the sink smelled a little plastic, but then it all went away.It works quietly, at the first speed you can generally say silent, does not interfere with sleep. It cleans the air well, works properly, for the entire period of operation there were no problems with washing. Not a single breakdown, failure, and more.
I also like the design, it looks solid and stylish!
The design is nice, the sink looks decent and I also like its compactness.

Not expensive, compact, cleans and ionizes the air well
Minuses
The first time it smelled of plastic
