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.

I bought this for my granddaughters room - she is allergic to my cats. It seems to work very well. I would recommend.

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

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

It’s working fine, but it’s small and take a while to purify air in the room

Just started using it and it’s working great, love how it lights up, and it’s very quiet, but I recommend getting more filters if you can for when the first filter runs out. And when you get it you have to open the filter at the bottom and get the power cord out or else you would be confused.

I ordered this because I have CAT PEE PHOBIA and it’s worked very well, I ordered 2.. one goes next to the litter box and we sleep with one next to the bed!

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!

It says sleep mode on here but there isn’t a button for that. I have used this for a month. U can see in the picture the comparison of the old and new filter and how it pulls all that crap out of the air that we breathe. I got it because allergies were soo bad.. this definitely has helped me. It’s kinda loud but the sound Helps me sleep and I noticed I have been sleeping better!
