Neighbor smoking weed

Hi! Best way to keep your apartment smelling fresh is a air purifier. I use Blueair 311i max. It covers over 3000sq ft. I’m in a 1000sqft apartment and the overkill on purifying is worth it. I smoke weed occasionally inside and within an hour or so, it’s gone. Good luck. You can always report it. Sm

Anyone using air purifier here?

I’ve been using a Blueair 311i Max for about a year now. My indoor AQI used to be around 45 to 60 on normal days and sometimes higher when cooking. On auto mode it usually drops below 10 in 15 to 20 minutes. It’s honestly a relief to see the sensor light turn from orange to blue. When I was first lo

Help! I can’t identify which model this is for the life of me. Even AI has no idea

It’s a 311 auto that is an older generation of the 311i max and the filters are very different. My review https://housefresh.com/blueair-blue-pure-311-auto-review/

Because the AOC Carbon Filter is actually washable and uses real pelletized carbon, unlike the "carbon-coated sponges" you see in cheap clones. Best for: Most living rooms/

Good air purifiers for smoke at the moment - What actually works?

If you’re staying in the $300–$600 range, I’d probably look at the Winix 5500-2 or the Blueair 311i Max. They both have HEPA + carbon, and the carbon actually makes a noticeable difference for cooking smells

Costco: Winix C909 or Blueair 311i+?

Well the actived carbon filter does help a tiny tiny bit with odor, but not much since you need pounds of actived carbon to actually see a difference, it’s much better to open a window/door and use a fan, aka ventilation for odor. So this shouldn’t be a deciding factor, I’d say ur good regarding thi
