I've been looking for air purifiers recently, and the brand that seemed the best in terms of actual filtration, noise, and cost, as well as how long filters can be used before replacement + the cost of replacement filters is Levoit. They have a pet-specific true HEPA air purifier for $130. You might be able to find a deal for Black Friday or something too, which could bring that price down.
You can also make "mini" Corsi-Rosenthal boxes with smaller filters and fans vs the large filters and box fans.

Reply to comment by pan567 in Could someone recommend an air purifier that doesn't need the filters thrown out and changed? I am willing to clean them of course! I have BAD allergies and 3 cats so it needs to work well in medium size areas. by Relaxandbreath
