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

Best air purifier money can buy?
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

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

Apartment smells like weed/cigarettes and it's suffocating me. Desperate for relief before I go bankrupt staying at a hotel
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

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

In need of advice.
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

Best Air Purifier for medically fragile kid with lung issues. Concerns Wildfire smoke, wood burning stove, pet dander, mold
With a 150 ft^3 bedroom, you need a CADR of 100 to get the recommeded 5 air changes per hour (assuming 8' ceilings). You could put something like a Coway AirMega ProX in the bedroom. On silent mode, I measured it at a CADR of 170, and there's nothing wrong with overkill. And it's probably quieter th

How long for new-filter smell to dissipate on the Coway Airmega ProX?
I appreciate the upvote. I was blissfully unaware that down voting was even a thing here. I am pretty new to this forum and hadn't noticed. Kindof sad that I know that now! I appreciate all your calculations.. I have done much of the same trying to find the right combo of dB, CFM, and cost. And yeah

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
