We bought one for my home because of allergies and we live downstairs sometimes it’s A musky smell all gone now .it will tell you how high the pollen count is in the room. Also this will detect all kinds of fumes like from a burner. Also my salon bought one for the fumes for me because of health issues and it really made a difference with chemicals and the smell.very quiet. My clients always ask about it and I highly recommended it to everyone.Thank u for clean air.
