Please read the AutoModerator comment. Air purifiers aren't good at reducing visible dust as it's larger and heavier than "invisible" pollutants like PM10 and PM2.5. The same goes for pet hair. Sans is terrible. Shark is mediocre. Avoid both. Coway is generally one of the highest quality consumer-gr

See the AutoModerator comment. Air purifiers aren't good at reducing visible dust or pet hair as both are large and heavy compared to "invisible" pollutants like PM2.5. See the sticky post at the top of the subreddit and our other subreddit resources on dust: I need an air purifier for dust. What sh

So unfortunately cigarette or marijuana smoke isn't just particulates, but also gases/vapors/odors/VOCs. You need many pounds of activated carbon and/or other sorbent media for gases/vapors/odors/VOCs. Heavyweight sorbent media purifiers are very loud, very expensive (~$600 and up), and clean the ai

Purifiers aren't good at reducing pet hair, if that's a benefit you're after. It's very large and heavy compared to microscopic pollutants like PM2.5. Only hair floating very close to a purifier's intake(s) will be captured. The two Levoit Vital models are definitely better than their Core series. T

Housefresh.com's reviews are useful, because they measure sound and CADR using a consistent methodology, allowing you to compare among units. They've tested the three you mention. I'd suggest making a table of CADR and noise at each fan speed from their reviews. That's what I did. Based on a quick l

Also, if you have the resources, invest in a good air purifier. The one is a Coway airmega Prox. It is a true HEPA with carbon for odors and it’s massive to move a lot of air. But ya talk to the neighbors, don’t be confrontational, just say what you said here. Toke up, but we got a baby and are asth

Per the AHAM 2/3 rule, a 732 sq. ft. apartment would need minimum CADRs of 488 CFM. The most stylish is probably the IQAir Atem X. It's made in Germany. But it has a top Smoke CADR of 415 CFM. It's also very expensive at $1,399.99. The Coway Airmega ProX has a top Smoke CADR of 568 CFM. It has wheel

Just ignore the coverage claims. The 2,126 sq. ft. value applies to 2 Air Changes per Hour (ACH). I would take the top Smoke CADR and multiply it by 1.5 to get the largest room size. For the Coway Airmega ProX's Smoke CADR of 568 CFM, this means the largest room size would be 852 sq. ft. with an 8 f

For 600 ft^2, and assuming 8 foot ceilings, you've got a volume of 600*8 =4,800 ft^3. To get 5 ACH, you need a CADR of 4800/12 = 400 CFM. There's no single purifier that gives that CADR without being loud. The closest is the Smart Air Blast MKII, which, according to Housefresh.com, is 41.9 dBA at 37

Neither the Winix C909 nor the Levoit Core 600S-P would be enough. Per the AHAM 2/3 rule, a 2,400 sq. ft. home with 8 ft. ceilings would need minimum Clean Air Delivery Rates (CADRs) of 1,600 CFM. Since you have cats and a dog, even higher CADRs would be a good idea. There's no single consumer-grade
