This might be premature, but I read Condumers Report and this purifier was highest rated as well large cleaning volume. It is big so you need to think about location, but given it purifying volume anywhere is prob ok. The only real downer was expensive filters once a year and noise at low speed. I found the purifier was very very quiet in fact a low speed I needed to put my hand over vent to be sure it was running. So long term per CR it’s great and from my experience very very quiet. It’s a serious investment, but serious purifiers seem to run $500 to over $1000 with more noise and poorer performance. Given the potential for years of service (I hope at least 10) it seems like a good investment. I have not tried all the modes arrrggghhh so many so my views might change but out of the box it’s great.

It has been operating 24/7, keeps the air clean, and is quiet.

This is a necessity for clearing out spaces after science projects. Great purifier.

Initially purchased an Airmega ProX and Airmega 350 to supplement our older Alen Breathesmart flex. Surprisingly, the larger ProX is the quietest of the three. It emits a soothing sound on level 2 and on level 1 it’s hard to hear it running when more than a few feet away. As someone that struggles with chronic allergies and allergy related headaches, the air feels very clean and our cat has been sleeping a short distance from the ProX due to the soothing sound. The main downsides of the unit are the filter costs and the size, however, Coway has been selling filters discounted on their website. The difference in build quality and sound compared to the 350 was enough for us to return the 350 and swap it with a second ProX for our oversized bedroom. We run both now at 24/7 on level 2 no problem, not audible during work meetings or anything.

I believe that this air purifier has significantly reduced the effects of my seasonal allergies. It seems to be working as it should. I did not check the size measurements of it when I ordered it. It's big, but it's quiet. This is a Consumer Reports recommended product. Prior to my purchase, another brand kept advertising on my phone. Whatever it is, it did not make the Consumer Reports list. You might want to do your own investigation before you buy stuff that pops up on your phone.
