Smart Air Blast Mk II vs. Coway Airmega ProX
I agree trying a different set of filters is a good suggestion, which I why I've already done that myself! 😄 A couple of weeks ago I contacted Coway, and they sent me a new set of filters. They've been running for about five days, and emit the same odor, though it's possible they're airing out faste

How long for new-filter smell to dissipate on the Coway Airmega ProX?
Thanks for the additional perspective. I though it might be a particular problem with the Coways, because I didn't notice a smell from the Winix 5510, and the smell from from the BlueAir Signature was faint; but I had noticeable issues with both models of Coways I had tried.

Coway Airmega 100 vs Winix C535
75ft by 50ft with a low ceiling. That's a huge room - 3,750 sq. ft. I'm guessing there are missing decimal points. Consumer-grade air purifiers aren't designed to remove lead dust as such. I know you're on a budget so obviously it's better than nothing. But something like a Winix doesn't have airtig

Smart Air Blast Mk II vs. Coway Airmega ProX
Have you considered a few different smaller units instead of one big unit? It’s a large space and normally you get better coverage and flow from multiple units. It would also keep the noise down because you could run them all on the lower setting. Also a good idea, and yes I did consisder that, sinc

Dog and myself have bad allergies. Need advice
the clean air delivery rate of this model is only 200. that’s less than my $100 winix. i have a winix c545 and a coway airmega and i researched for weeks. i would get one for each floor of your house.

Coway Airmega Mighty vs Winix 5500-2 (EU, 62 m², 2 cats, newborn) – which one should I choose?
Winix. It won’t be best odor reduction but you won’t get any with the Coway -1512hh

Coway Airmega 250S or Mila Air 3?
Do not buy Mila. Their reliability/build quality is terrible and customer support is bad. See my comment here for other complaints. Purifiers aren't good at reducing pet hair as it's very large and heavy compared to "invisible" pollutants like PM2.5. Ceiling height is needed. If the ceilings are 2.4

How long for new-filter smell to dissipate on the Coway Airmega ProX?
I have 2 Alen 75i with Fresh filters that have pelleted carbon. No smell at all. I bought a Coway 350 and the off gassing was terrible. After weeks, gave up and sent it back. I don't think it was the filter because I smelled it when I first got it and it wasn't running. I think it was the plastic. I

Considering an apartment near a highway, will a very high quality air purifier save me?
Thanks for the detailed response. I was looking at the Coway ProX too, but gravitated towards the Austin Health Mate Plus because of how much more carbon it has to fight gases. From my understanding, even though the Health Mate Plus doesn’t perform as well against particles due to the reduced airflo
