Check out HouseFresh, they do reviews and testing of air purifiers. https://housefresh.com/ Also make sure to check if your utility company does rebates on air purifiers. I was able to get a Winix A230 for $10 shipped because I got it through my utilities website.

I just got the Winix A230. Mine is set on auto and has consistently programmed itself at low and I can't hear a thing.

I have a Winix A231 and it seems to do pretty well, I smoke weed in my house/living room regularly and you wouldn’t be able to tell, I leave it running 24/7, 2 years in and still going strong However you’ll want to consider multiple if you’re having constant dust problems, also make sure you regularly change the HVAC filter maybe also up the MERV value. Odor can be controlled mostly by charcoal filters. Make sure to change those regularly as well

The Winix A231 for the main part of the house and a Bionaire Desktop True HEPA Air Purifier for my bedroom. They are cheapest at Walmart. I thought I might need a third one because my house is shaped like a U but the two together work fine. I didn't even have them turned on over the summer but now that the rains will be kicking in and doors closed I have them on again. Both have washable/reuseable filters.

Hello, living in Buffalo, NY, USA and room in question is small, 200 cubic ft. Currently have a Winix 5500-2 and A230 elsewhere in house. Looking for a purifier that meets needs below: 1) HEPA Filter 2) Non ionizing 3) **Has actual carbon pellets** (like the 5500-2) and not just a carbon impregnanted filter (like the A230). Primary concern for this purifier is for odor. 4) As small as possible (A230 size or even smaller, looking for smallest size options possible) 5) Less than $500 Thank you!
