I use a BlueAir purifier at home that I love! It’s a little pricey, but I consider it an investment in my health. I have two double coated breeds and as much as I do my best to keep them well groomed, it’s been a godsend during allergy season! It filters out viruses, mold, pollen, pet dander, dust and more.

Ours stopped just over 12 months. It's not worth it! It was too expensive. Not commercial grade.

We have two of the Levoit Core 300S, and in the last year, we had had both replaced under warranty. Both had their motors fail. They first started making a squealing noise, which got louder and louder. First failed within 30 days, second after six months.
