Air Purifier Filter Cost Calculator

See the estimated total ownership cost for popular air purifiers — initial price, replacement filters, and electricity — based on verified manufacturer data.

Affiliate disclosure: we may earn a commission on qualifying purchases through our links, at no extra cost to you.

How we calculate ownership cost: All data comes from verified manufacturer specifications, ENERGY STAR published energy data, and current retail prices. Filter costs use the manufacturer's recommended replacement interval — not a blanket 6-month assumption. Electricity estimates use the US average residential rate (16.5¢/kWh). When canonical data does not verify a field, it is labeled "Not verified" rather than estimated.
