Good little product. Three levels of filtering. High is noise causing, while medium is silent. Doesnt cover much space, confined filtering is ideal.

I bought two(2) for family. From day one, both made so kind of noise like metal grinding when we put into sleep mode(speed), we could not sleep so turned it off. I did send a message but they did not respond. So I did return those on Feb. 7, 2023 for a refund. Maybe it happened just for us?

No problem at all it’s whisper quiet. The only thing is even when you turn the light off it’s still got a little blue light that’s bright. (See photos). I’ve slept better in my room now that it’s been on. Not waking congested!

This thing is cheap, but seems therefore...cheaply made. If you want to run it on high a lot, it does not seem to hold up, as it pretty quickly began making weird noises as it ran, after only a few weeks running it on high consistently. I upgraded to a better model (levoit) which is more than worth it. (Those last all the time on highest setting, and never make any squeaking noises....ever. these cheaper made units might only be useful when using more casually/only on low setting, but does not hold up well over time.) Also even after vacuuming the filter, the air coming out still smells bad, wheras larger purifiers you can vacuum filter + make it last longer. So its another 10-15 bucks for a tiny filter, on a unit that makes noise, and doesnt last well. Just spend a little more money to get a levoit, which you can vacuum those filters and it evens out that way, for way better performance, and no noise.

This is the second one I bought. The first one is very quiet. You would hardly know it is there. The second one works well but has a bit of a rattle sound. Not horrible, just very noticeable. I have not used either with essential oils

This air purifier is small but effective. I use it in the family room where my dogs hang out the most. Nuetralizes and odors and cuts down on dust from dander. Its also very quiet.

Easy to clean, low noise, doesnt take up a lot of space, and cleans the air well.

Again filters to expensive

Just the right size for my bedroom. A little noisy.

Freshens well
