Frequently asked questions
How big a room does the Dreo DWAP09AS cover?
AHAM suggests it for a room up to 225 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 Dreo DWAP09AS?
Its AHAM Clean Air Delivery Rate is 161 for dust, 145 for smoke and 163 for pollen, with a PM2.5 CADR of 153. CADR is cubic feet of clean air delivered per minute — higher clears a room faster.
Does the Dreo DWAP09AS use a real HEPA filter?
Its filter is listed as True HEPA (H13). True HEPA captures 99.97% of particles down to 0.3 microns.
How much power does the Dreo DWAP09AS use?
About 27.1 watts on its smoke-clearing setting, which works out to 5.4 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 Dreo DWAP09AS?
We link an Amazon search that we confirmed shows this brand, not a listing matched to this exact model — AHAM model numbers often differ from the name a retailer sells it under. Check the model number on any listing 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.
