I have two small coways (meh), Dyson (meh, but very good for heating!), Levoit 600S - very good and just got blueair signature - so far very happy.

Go to the Blueair website and look at all their air purifiers. Some are on sale for almost $100 less. Look at the new Blue Signature on sale. It has a washable fabric pre-filter, which is great for dusty rooms. I think Blueair purifiers are terrific, and never consider buying any other brands any longer.

BLUEAIR for the win. Saved me twice from getting covid (sick visitors). Just upgraded to the newer Signature version.

I have the Winix from Costco and the Blueair Signature SP4i. IMO, they work about the same. The app for the Blueair has a feature I like, where it can be set to know when you’ll be arriving home. It uses your phone’s location to do this. I don’t want it running for the 10+ hours that the house is empty, so it works for me. But the main reason for the Blueair is its look. The Winix would look horrendous in my living room.

It’s honestly so good! I initially started with the 511, 5 years ago and recently just upgraded to the blue signature (during Black Friday) which is the prettiest out of the bunch! lol I’d absolutely get the 311 for our other rooms— gotta wait for another sale tho lol

Check out the Blueaire Signature. Looks like a small side table. You can place small items on it like the small holiday display I have on mine.

I just got my Blueair signature and it’s making a loud clicking motor noise on speed 1. I’m returning it. Not sure if I should buy another one.

I have a blue signature and love it (we got it as a gift), the app is very easy to use and I have noticed an improvement in dust and also my allergies. I was really impressed with its ability to detect what’s in the air - I’ll light a candle about 15 feet away and it’ll kick on. I’ve never had a levoit so can’t speak to that.
