Housefresh.com's reviews are useful, because they measure sound and CADR using a consistent methodology, allowing you to compare among units. They've tested the three you mention. I'd suggest making a table of CADR and noise at each fan speed from their reviews. That's what I did. Based on a quick l

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

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

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

For an extra-large room 650 square feet or more Consumer Reports recommends: Coway Airmega ProX Anything cheaper has just an OK, poor or bad review. Subscription required.

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

See the AutoModerator comment - purifiers aren't good at reducing visible dust, as it's large and heavy compared to "invisible" pollutants like PM2.5. VOCs are usually difficult to mitigate with purifiers. Heavyweight activated carbon or sorbent media models are costly and very loud. Depending on wh

So I can't make a informed recommendation without room dimensions. The only filters that will be reusable are the pre-filters. HEPA or other pleated filtration media must be disposed once clogged. Tiny particles are trapped in the filtration media, not just on it. Keep in mind purifiers aren't good

If you want things to truly be good, most air purifiers WAY over state the area the can cover. The general rule is 2/3’s of the square feet of the area you’re trying to purify (assuming there’s not walls and stuff in the way) of CFM. So for a 600 square foot studio you’d need 400 CFM. Here is the cu
