Sweet deal on a great air purification unit

Solid unit for air purification. Small footprint is nice. It's got a three stage filter. The last stage is carbon and that should filter the air real good. There is a way to add liquid scent so that the outputting air smells good. Thief replacement filters are $10 each and it's probably a good idea to go ahead and get a few. APH 4000 is the filter model and they are available at Walmart, $20 for a pack of two.

This thing is amazing!

This thing is awesome! I've never seen any of these that sense odor or particles in the air like this thing does. It also has pet mode that runs a little bit harder for animal odors but it always keeps the air fresh and it's a great conversation starter when people see it kick on when something is obviously floating around in the air.

Great air purifier for the price!

Really happy with this purchase. Setup was super easy and the instructions are printed right on the unit. It’s a good size — not too big, fits great in a bedroom. Runs very quietly, especially on sleep mode, so it doesn’t disturb anyone at night. Love the green display that shows your actual air quality (PM2.5 reading). Easy to use touchscreen controls. The double filter system seems solid. Would definitely recommend!
