FAQs
Is air purifier with washable filter really worth it?
For most people, yes — especially if you have allergies, live with pets or wildfire smoke.
How much should I spend on air purifier with washable filter?
Expect a realistic minimum of $120–$220 for a quality HEPA unit that will last five years. Spend more if you want smart features or larger rooms.

All the time, on Auto, if you can. The filter lasts longer because the fan slows when air is clean.
