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

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

If you need to filter particulates (examples: mold spores, auto dust, soot, pollen, dander, etc.) and gases, you need two types of air purifier. I'll cover purifiers for gases/fumes first. Unfortunately an auto shop will have very complex gaseous air chemistry in all likelihood. And your space is ve

That's not what the data shows. I've not tried the Alen, but I've tried several other air purifies, and have found the reviews on Consumer Reports and HouseFresh.com to be accurate. And based on those reviews there are other units that provide less noise for the same clearance rate. Specifically:SPE
