I have an air purifier similar to this model which is on sale ATM. https://www.bestbuy.com/site/filtrete-370-sq-ft-true-hepa-air-purifier-black/6472746.p?skuId=6472746 I like that it has screens that catches a lot of hair and dander that I can vacuum out.

Vacuuming and steam cleaning helps. You should also wipe surfaces and used compressed air sometimes.

I like this air purifier I got for sale on best buy. It has a couple pre filter screens that can be removed and cleaned. https://www.bestbuy.com/site/filtrete-290-sq-ft-true-hepa-air-purifier-white/6472745.p?skuId=6472745&loc=pdpShare&ref=app_android
