The standout number

Frequently asked questions
How big a room does the Levoit LAP-C171-ACAR cover?
AHAM suggests it for a room up to 53 square feet. That rating assumes it runs on high and cleans the air about 4.8 times an hour. For faster cleaning — say for wildfire smoke or allergies — size it to a smaller room than the maximum.
What is the CADR of the Levoit LAP-C171-ACAR?
Its AHAM Clean Air Delivery Rate is 39 for dust, 34 for smoke and 61 for pollen, with a PM2.5 CADR of 37. CADR is cubic feet of clean air delivered per minute — higher clears a room faster.
Does the Levoit LAP-C171-ACAR use a real HEPA filter?
Its filter is listed as HEPA-Type. "HEPA-Type" is not the same as true HEPA — it captures fewer of the smallest particles.
How much power does the Levoit LAP-C171-ACAR use?
About 6.6 watts on its smoke-clearing setting, which works out to 5.2 CADR per watt — a measure of how much clean air you get for the electricity it draws. It is ENERGY STAR certified.
Where can I buy the Levoit LAP-C171-ACAR?
It's a retail unit — we matched its Amazon listing, linked on this page, so you can check the current price and seller. The replacement filters are the recurring cost — check those before you commit to a brand.
Sources. Clean Air Delivery Rate (dust / smoke / pollen), PM2.5 CADR, suggested room size, ENERGY STAR status and power draw come from the AHAM Verifide air-cleaner directory (the industry's independent CADR test). Average CADR, clean-air-per-watt and the percentile figures are computed by Verified HVAC Data from those published ratings. We publish no star ratings and take no payment for placement. "Not published" means AHAM's record doesn't disclose it — we never fill a spec with a guess.
