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/

Top 10 Best Air Purifier in 2026
The "Reddit Gold Standard": WINIX 5510 Despite being an older chassis, this is still the undisputed king of value in 2026. Why? 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

Which of these air purifiers should I choose for asthma & pets?
See Rule 4: Information For Air Purifier Requests or the AutoModerator comment - what's your budget? Per AHAM 2/3 rule, the 600 sq. ft. living room needs minimum CADRs of 400 CFM. The 350 sq. ft. bedroom needs min. CADRs of 234 CFM. Calculations assume an 8 ft. high ceiling. But if you have allergie

Costco: Winix C909 or Blueair 311i+?
I'm unsure about ion concentrations the Blueair produces vs. Winix, so you may or may not notice a difference. For Blueair and Winix, the activated carbon angle is moot. These brands (and most other common consumer-grade purifiers) have far too little activated carbon or other sorbent media by weigh

Noob questions on what to get for wildfire smoke.
I'd recommend something like Coway 1512hh or a Blueair 311iMax. I've got both and a few sensors that show they work well for wildfire smoke the Coway I've had for many years and it's still running like new.

Best Air Purifier for mold, fungus, and allergies - that's available at Target
I would buy either the Levoit Vital 200S or Winix T810. Third choice would be Blueair Blue Pure 311i Max I guess (this has an always-on ionizer). Try to keep the purifier on the top airflow speed/setting for the best cleaning performance. Lower settings will not clean the air as quickly.
