I have used this, yes. Sadly it won’t save you from the general dust bunnies under the couch, etc but it does take a lot of pet hair and dust out of the air. There is still pet hair on the couch and floor but it cleans the air well - which is good for the allergies. You know when the dog scratches itself and you see hair flying thru the air? That’s the stuff it’s filtering out. And all the dust in the air being kicked up by fans, the heat turning on/off, people walking thru the room, etc. My parents have two going in their large living room. We use painters tape to hold the filter on so it’s easy to switch out for a new one. Not pretty but it works! You’ll be amazed at what the filter looks like in a couple weeks - dirty!!
