Levoit Core 300 or Blueair 411i. They're both super quiet, lights can be turned off, perfect for dust in a bedroom.

Levoit or Coway are the safe bets. True HEPA, actually quiet, filters aren’t stupid expensive, and people genuinely notice less dust/allergy symptoms. Dyson is overpriced for what it does, Blueair is good but filter costs add up. Size it properly for your room and run it 24/7 👌

We use the Blueair 311i max and 411i max, you can order a slightly more expensive smokeblock filter for them specifically made to filter out the particles in wildfire smoke. These units will also give you a readout on your phone to monitor the air quality in your home.

We love our BlueAir filters. We have a 211i Max for our main floor (overkill) and a 411i max for our upstairs. Would recommend them to anyone!

I second the Blueair purifiers. I have the 211+ non auto in my living room and the smaller versions in my bedrooms. I've had the 211+ running for about ten years and still going strong. The smaller ones I had to replace recently. I got the table top Mini Max through Costco in a 2-pack and I regret that size. I'll get the smaller standing 411 ones again next time.

We have been using Blue Air for over a decade and have been happy with them. Have the 411, the pure fan, and our first one the 400. Had a couple fan issues over the years but customer service has been good so far.

Blue air junk? I have been using blue air for a decade and got one for each of my staff conference rooms during the COVID response - none of us got sick and we were in person for over a year. These things have been running for years daily and I’m a fan…

I think anything name brand with a hepa filter will be fine for you. a small one is fine if its for a bedroom. I adopted a cat and my room began to smell like a petsmart. I was lucky enough to find a $100 air purifier on Facebook market for like 20 bucks, my room smells completely clean and neutral now. I firmly believe its a big difference and helps make your room a more enjoyable space. if you dont wanna do any browsing, I use the blue 411 and I like it a lot.
