  • Cleans air really well & quiet

    Bought this about a month ago & I can really tell the difference. The only thing Im not sure about is the auto & the blue light. Every time I turn it on it goes to yellow for maybe about 30 seconds then turns blue . Can it really clean the air in a room that quickly? Not sure. All in all I still am pleased with the purchase. Would recommend this brand to anyone.
