Powerful enough to clear large rooms quickly, with several owners noting it pulls odors and smoke out of the air fast Very quiet on its lower settings and night mode, often described as a soft background whoosh Real relief for allergies and pet dander, called a godsend during allergy season by multi-pet households Owners complain about

YouTube “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.”— Jargon_Hunter on

YouTube “I'm so happy with this purchase, and I doubt I'll ever buy a different brand.” “My newly lupricated 400s bearing was silent for 1 month and started wining again after it. Instead of replacing the bearing I might replace the levoit.”— @LordDarthNihilus on
