Best Value Air Purifier? (Coway, Winix, Blueair, Shark, Sans, etc)

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

aesthetic/stylish air purifier with high CADR / efficacy recommendations

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

Rabbit air vs blue air vs Coway

With that budget the best option would be a Coway ProX as it's around $650 at the moment in beige. https://cowaymega.com/products/airmega-prox Just the filter replacement costs are still high, but for particulates you probably only need to change every 2 years. The Coway ProX is better than the Cowa

Is the consensus Coway Air Purifiers?

What are you and u/BatFull9947 talking about? 😂 For particulates, I've recommended loads of purifiers that are nowhere near $1,000. And if they tend to be expensive, I tell people to not pay full price. E.g., the Coway Airmega 400 ($649 to $349) and the Coway Airmega ProX ($999 to $649), both of whi

Coway Airmega Pro X vs IQ air health pro plus xe

It has the highest CADR while being quieter than your two options listed. I have one in my living room and it’s great, although it energy inefficient. It’s essentially just a modified Chinese filter fan with a grill. I also have an IQair healthpro plus and wouldn’t recommend it very highly. It’s jus

Deciding between Winix C909 and Coway Airmega 400 (Bay Area, CA, USA)

Hi, I created the newest iteration of the Buying Guide. I didn't include the Coway Airmega 300 because in the past, the Coway Airmega 400 would be discounted frequently enough to justify its purchase instead. Annoyingly, there were no good Black Friday or Christmas sales for the Airmega 400 or Airme

Air purifier for 1200 sq Ft apartment

See the AutoModerator comment. Purifiers aren't good at reducing visible dust particles as they're large and heavy compared to "invisible" pollutants like PM2.5. An even stronger argument could be made for dog hair. If you don't have one already, I'd get a good quality bagged vacuum cleaner with a H

Air purifier recommendation for open living room

Assuming you haven't picked something out already... The Medify Air MA-112 (V2.0) is powerful, but loud on the top airflow speed/setting. Per the AHAM 2/3 rule, a 1,872 sq. ft. space would need minimum CADRs of 1,248 CFM. So any one consumer-grade purifier will fall short. I would go with the Coway

Recommendation for air purifier for allergens

You're right, for allergies you should aim for 5-6 air changes per hour. Out of all the air purifiers we have tested, these are the ones that could provide that for a space like yours: Levoit EverestAir Smart Air Blast Mini MKII IQAir Atem X (the most expensive option) Coway Airmega ProX Levoit Core

One Purifier or Two for my 670 sq. ft. area

There's no app for the Coway Airmega ProX, so you'll have to use buttons on the purifier. Yes, it can be run continuously on the same speed. (Manual speed choices are speeds 1, 2, and 3.) There's also a "Turbo Mode". According to the ProX owner's manual: "Turbo mode accelerates the air purification
