Filter Replacement Costs

Must Know

The hidden expense. Annual filter costs can exceed the purifier price. We calculate true cost of ownership for every model.

The Confusion We Clear Up

Air purifier marketing is designed to confuse. Here are the three biggest traps.

"True HEPA" vs "HEPA-type" vs "HEPA-like"

None of these terms are regulated. Only H13 HEPA meets the 99.97% filtration standard. Everything else is marketing language that sounds the same but performs worse.

Room size claims are inflated

Manufacturers advertise 1,000 sq ft coverage. At proper air exchange rates (4 ACH), that same unit effectively covers 250 sq ft. Always check the CADR number, not the room size claim.

CADR is the only number that matters

Clean Air Delivery Rate measures actual cubic feet of clean air per minute. Higher CADR = more air cleaned. A 200 CADR purifier handles ~300 sq ft at 4 air changes per hour.
