Dust catcher
The Okaysou air purifier seems to be doing a good job in bedroom of removing dust from the air.  Less dust on furniture, sleep better and less nasal congestion.  Low sound in sleep mode. Have only been using for about one month but think it is a good product at this point.  I may get two more for other rooms. Don't know how long filter will be effective and it is my understanding that replacement filters are expensive - ?
