Myself and my husband smoke and due to our hardwood floors it seems like I can’t keep the dust down so our allergies stay a mess and then I have asthma on top of that. Since getting this air purifier it has helped our breathing and my asthma tremendously. We neither one stay choked up like we normally do and the air quality is so much better. And it’s not to loud like some are. Well worth the money. And has the biggest filter I think I’ve seen on one. Which means a lot.
