ProX

Coway and Winix are fairly popular brands. Make sure it has activated carbon filter as plenty of models don't have it. Also HEPA filter (certified) and that replacement filters are easily obtainable. I understand people often look for budget options but this is a long term purchase and try not to sa

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

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

Wirecutter has been recommending the Coway Airmega for years now. I’ve bought several for myself and family (especially during wildfires) and they’ve performed brilliantly. Filter replacement costs are not terrible. You can use the HEPA filter for like a year and it costs maybe 40 bucks to replace.

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!

For the second I'd put it in the corner between the slated doors. It will pull from the entrance and the

Oops sorry I misread where you said budget was $250! I'll leave this here just in case it's helpful for someone else down the line. Looked up the C545. Claims it cleans 436 ftsq every 15 minutes (4x per hour). That would be on high speed. There are a few other purifiers that have better cleaning per

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

the carbon filter not being "useless" thing - im with ya. thin carbon pre-filters on budget units are largely decorative, but the Airmega 160 has a more substantial carbon stage than most at that price point. if its making a difference on smell, its working. for a post-renovation situation with asth

I own Xiaomi 2S air purifier and it's going strong even after 7 years. The replacement filters were not available during the last pollution season but now it's available on mi store. I simply washed the hepa filter and reused during that time, noticed a slightly reduced filtering but for a small clo
