HEPA AIR FILTERS
These are 3 HEPA air filters I would recommend based on both my experience and reviews. Both HomeLabs and Pure Enrichment air filters work well and are generally meant to be used in a normal bedroom sized area, while the IQAir is generally more effective at cleaning the air and is also meant for a larger room than the other two.

There are, of course, many different air filters you can find on amazon that would also work very well. These just happen to be the 3 that I have experience with.
