About Mildew Hall
Mildew Hall is an independent buying-guide site about home air purifiers. We help you work out which kind of purifier fits your room and your problem, and which models are worth a look.
Our guides are written for homeowners, renters and anyone with a damp basement, a smoky room, a shedding pet or a stuffy bedroom. We use everyday words, and we explain terms like HEPA, CADR and activated carbon when they matter.
What we cover
We cover HEPA air purifiers for the home. That means picks for musty basements and bathrooms, cigarette smoke, pet hair and cat litter smells, plus guides on room size, placement, filters and running costs.
We also compare popular brands like Levoit, Coway, Winix, Blueair and Shark, and review single models that many people search for.
How we work
For every model we cover, we read the specs, the maker's own description and what buyers often report. We check coverage, filter type, noise and what replacement filters cost to keep running.
Then we write plain guides, side-by-side comparisons and clear picks. You can read the details on our How we research page.
What we don't do
We don't sell air purifiers, and no brand pays us to rank its products.
Mildew Hall isn't affiliated with Levoit, Coway, Winix, Blueair, Shark or any other maker.
We don't give medical advice. An air purifier is a household appliance, and it isn't a treatment for any condition.
We don't claim to have tested every product ourselves. When we pick something, we tell you why, based on its specs, its features and buyer feedback.
How we earn money
Some links on this site go to stores like Amazon. If you buy through them, we may earn a small commission at no extra cost to you.
That never changes which products we pick. Our affiliate disclosure has the details.
