Who it's for
Large living rooms and open-plan spaces that need real air-cleaning power.
The standout number
Smoke CADR of 270 — 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 Winix T810 cover?
AHAM certifies it for rooms up to 418 sq ft. In a room that size it cleans the air about 4.8 times an hour on its top speed (our math: 270 smoke CADR x 60 / the room volume, with 8-foot ceilings). In a room half that size (209 sq ft) it would clean the air about 9.7 times an hour.
How much does the Winix T810 filter cost, and how often do you change it?
The maker says: “Lasts Approx. 12 months; Intervals between filter replacement may vary depending on environment.” The matching genuine filter (360 All-in-One True HEPA Filter) is $74.99 on Amazon. Changed every 12 months, that is about $75 a year. Maker source.
How do you reset the filter light on the Winix T810?
The maker's manual says: “01. Filter Life / Filter Reset Button: A quick press will show the remaining filter life indicated on the front display (F99 ~ F00). A long press of 10 seconds will reset the filter life indicator. - Use when replacing the filters. - Filter Reset Button can be used when the power is turned off. - The filter life will be reset to 100%.” Maker source: T810 & T830 User Manual.

Frequently asked questions
How big a room does the Winix T810 cover?
AHAM suggests it for a room up to 418 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 Winix T810?
Its AHAM Clean Air Delivery Rate is 272 for dust, 270 for smoke and 277 for pollen, with a PM2.5 CADR of 271. CADR is cubic feet of clean air delivered per minute — higher clears a room faster.
Does the Winix T810 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 Winix T810 use?
About 45 watts on its smoke-clearing setting, which works out to 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 Winix T810?
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.
