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

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

FWIW, I have bad environmental allergies to chemicals and smoke, both of which block my nasal passages and result in sinus infections. For years, the air filter I used was the IQ Air HealthPro Plus, which is modestly effective. More recently, I bought a Coway Airmega ProX, which seems to be more eff

I'd probably say the Coway Airmega ProX or the Smart Air Blast MKII for particulates (e.g., smoke particles). Both are quiet relative to CADRs and seem to be reliable. Neither model is good for gases/vapors/odors/VOCs though.

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/

Yes, Coway has had odor issues with its filters, and still does. Then again, most brands have, including Winix:https://www.reddit.com/r/AirPurifiers/comments/1hht4r6/do_all_purifiers_or_their_hepa_filters_have/ https://www.reddit.com/r/AirPurifiers/comments/1hhtma2/horrid_smell_and_bad_filtering_from_new_winix/ B

Just so you know, Jaspr would be very poor for gases/vapors/odors/VOCs. It doesn't have much activated carbon by weight at all. To boot, it's wildly overpriced for particulates at $1,199 or $999. Their marketing has been highly dishonest (fair warning: the exchange is super long). Jaspr's top Smoke

If you want the absolute best for the bedroom at night, you want the maximum airflow (so the air is filtered multiple times per hour) with the minimum noise, and for that you need a big air purifier running at its lowest speed. I'm currently testing air purifiers, and I've found the Coway Airmega Pr

4.8-5 represents the minimum recommended Air Changes per Hour (ACH), not CADRs. CADRs are the more important metric. See the AutoModerator comment (and various wiki page entries) about the AHAM 2/3 rule for particulate CADRs. A few notes. First, purifiers aren't good at significantly reducing visibl
