I have two Coway Airmegas (300 and 400) and one Austin Air Bedroom Machine. They've all been running for 24 hours a day for over 5 years and have held up great. They are all easy to move around. The Coways are light and the Austin Air is heavier but has wheels. If you don't want to clean the outer filter at least monthly, don't get a Coway. If you can't deal with something that's pretty loud on the highest setting, don't get an Austin Air.

I have a CR box with 6 PC fans. The throughput is just not enough to deal with the fire smoke.. ended up turning my actual purifier’s fan speed up. I have the Coway 300. Speed 3(200CFM) worst day 2 of them running.

Hell yeah. I have two air purifiers running 24/7 in my 1bd apartment and it makes such a huge difference

Sure! I have the Coway AP-1512 in my living room and the Coway Airmega 300 in my bedroom. Big fan of the Coway products. If you keep an eye on marketplace or Craigslist you can get a good deal on them secondhand since so many people bought filters during the fires and end up selling them

I have two of those for bedrooms and the bigger airmega 300 for kitchen/dining/living area. They've been working great for me (I get impacted by wildfires and my neighbors fireplaces).

Same here. We have two Coways, one in living room one in bedroom. Got one off Craigslist and the second on Buy Nothing. They've been super helpful for dealing with all the dust and cat fur. Now we need a dehumidifier.
