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

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

Pulmonary Fibrosis- need help with choice
Hello. Very sorry to hear about your husband's IPF. You're right to be wary of ChatGPT. I'm sure it's improving, but I've seen it produce inaccurate or totally incorrect information. Just a quick FYI: purifiers aren't good at reducing visible dust as it's large and heavy compared to invisible pollut

Small room vs large room purifiers
In the future, you may want to make a post in this subreddit instead. That would probably yield more views and responses. 😊 Since medium to large is very subjective, it's hard to give exact recommendations. "Cleaning performance" is usually best measured by the Clean Air Delivery Rate (CADR). Higher

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

Help Before Black Friday Sales End!
There are some Black Friday [BF] deals already, but I think there may be more to come in the week leading up to Thanksgiving or BF. I would generally recommend Coway first. They're one of the highest quality consumer-grade brands. I think their larger and more powerful models may not be discounted y
