Aircillin 2-Pack Air Purifiers for Home Large Room Up to 908 Sq Ft Each One, HEPA Air Purifiers for Bedroom with Aromatherapy, HEPA Filter for Smoke, Pet Dander, 99.9% of 0.1 Microns Particles Black

Great item. I placed one in my bedroom and one in between my dinning/kitchen and living space. I noticed a difference right away. They are quiet and the added, scent dots are a plus. You can put any type of scented oils you prefer, and they give you quite a few. You can also order the filters and the scent spots easily. It comes with a timer so can run all day and shut down at night or you can run at night with little to no noise. They are perfect size to set on a table or floor and do not take up a lot of room. I am very pleased with these units.

It works really well. And moves the air in my bedroom so well. Better than a fan

It is amazingly quiet and cleans the air like pure oxygen.

The price is great I do notice a difference because my family has allergies

So far so good. Very quiet. SUPER EASY to use. After reading the directions, just plug in and go. Timer, Scent Holder Sponge (an option to use) with refills. I bought them to see if they could eliminate the excessive dust and even out the different aromas and smells throughout the day. Six critters, desert air, tons of clays and sand, allergens, and wind like we don't have any buildings. Third day in and I haven't wrinkled my nose in confusion or thought (what's that smell). There's nothing to smell. Dust isn't present, but yet to be seen whether it helps that part. I looked at WAY TOO MANY of these before finally purchasing. I went with the HEPA filter (rather than filterless) as the options available were what I wanted and the price is terrific for a set. One is in my living room and one near the door in my bedroom. 2500 Sq Ft and no smells. No noise, not even soothing white noise. Ya have to be very close to hear them. I'm very satisfied with the purchase.
