I knew this product was small for the job I needed it for, my sons bedroom where he smokes. However, I have not noticed any change whatsoever. Everything appears to be working but just no change at all.

I like the product, my room smelled muggy and now it seemed to go away.

So far so good

First week works good and now it makes a little noise.

Edit after three months. Buy a flashlight and watch all the dust left around the device. You’ll notice you have clean air, but a dusty surface. You’ll need Lysol wipes to catch surface dust. And after, flashlight it again and you’ll notice more dust. The point being don’t worry about dust because is a Neverending Story with dust. This is the lyric that came to mind when I finally realized: Why did I never buy this? I used to flash my cellphone light at night to see a bunch of dust particles flying around my room. I slept with all that dust going into my nose. No wonder I had allergies. It’s all gone. Don’t forget to clean your ceiling fan before summer. Not one dust particle is flying around. And yet, we are dust. Fly with me.

I liked adding essential oil. Nice aroma therapy.

For a small unit it works great for a large room.

It’s good only for little spaces. The room is fresher and it’s really nice at bed time. The sound helps you fall asleep

Some times it rattles. Also weirdly if it is like 2 feet above your head it makes a ticking noise.

The price was great. The item works great in any room and very quiet.
