Pure 411i Max

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 live in Southern California, and the filters are great for fire season to keep the air clean inside. They also help when other things are going on outside like skunks, kicked up dust, the neighbors’ smoky fire pits, or even when it’s a bad pollen day. I’ve tried various brands and I still like the Coway AirMega 200M (same as the AP-1512HH). It’s not the quietest at higher speeds, and it’s not tiny, but it moves the air and filters very well. There’s a reason it’s long been the top pick of Wirecutter. If you want some more style, the various BlueAir models, especially the Pure line are very nice and also work well. They’re a bit expensive though. If money is no object, Austin Air makes some highly regarded machines. In general, UV and ozone are gimmicks. The biggest thing to look at are the CADR ratings. Higher numbers are good, they mean the unit is delivering more filtered air quicker. Always check replacement filter prices, often a good deal on a machine means they make money on selling filters.

Blueair works okay. It’s expensive but does work. Coway is definitely more performance for the money though.

It helps a lot. I bought it due to smoke but I’m happy to get rid of cooking and dog smells. I have one from Blueair.

We love our blueair also. Got a dog a month ago and happy to hear from guests our house doesn’t have a dog smell.

Seconding Blueair! We have a Levoit and a Blueair; while I have nothing bad to say about the Levoit, I personally prefer the Blueair (granted, it was about twice as expensive). We've got two medium-sized dogs, and - aside from the clumps of dog hair under the baseboards - you wouldn't know that we had any pets!
