These guys demonstrate the real impact of air purifiers
I also have the Medify, but have not seen a good replacement filter. I tried once on my MA-40, and it worked, but got clogged much faster. Air smell wasn't clean either. I tend to vacuum my filter out every couple of weeks to help keep them clean.

I need some suggestions for an air purifier to run inside my apartment while doing pottery on the porch
Do not trust ChatGPT. It's wrong on several fronts yet again on purifiers. When sizing purifiers, use AHAM's 2/3 rule. In your case, the bare minimum CADRs for a 444 sq. ft. space (with an 8 ft. high ceiling) would be 296 CFM. The PuroAir 400 has CADRs of: Dust: 262 CFM Pollen: 286 CFM Smoke: 236 CF
