Who it's for
A typical bedroom or living room that needs cleaner air.
The standout number
Smoke CADR of 161 — the number that decides how fast it clears wildfire smoke and fine particles.
The catch
AHAM's record lists no carbon stage. If odors or smoke smell matter, check the listing for a carbon filter before you buy.
What size room does the Levoit LAP-C341S-WCAZ cover?
AHAM certifies it for rooms up to 250 sq ft. In a room that size it cleans the air about 4.8 times an hour on its top speed (our math: 161 smoke CADR x 60 / the room volume, with 8-foot ceilings). In a room half that size (125 sq ft) it would clean the air about 9.7 times an hour.

Frequently asked questions
How big a room does the Levoit LAP-C341S-WCAZ cover?
AHAM suggests it for a room up to 250 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-C341S-WCAZ?
Its AHAM Clean Air Delivery Rate is 161 for dust, 161 for smoke and 172 for pollen, with a PM2.5 CADR of 161. CADR is cubic feet of clean air delivered per minute — higher clears a room faster.
Does the Levoit LAP-C341S-WCAZ 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-C341S-WCAZ use?
About 24.5 watts on its smoke-clearing setting, which works out to 6.6 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-C341S-WCAZ?
We haven't matched a retail listing to this exact AHAM-certified model, so we don't link one — AHAM model numbers often differ from the name a retailer sells it under. Search the model number above at your usual retailer and check what you find against the certified figures on this page. 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.
