Yes, for a room up to 392 sq ft at $179.99. But the 5520 is the same certified machine, so buy whichever is cheaper. If you can spend $6 more, the AT40 uses less power and is cheaper to own.
Winix 5510 review
The short answer
Yes. The Winix 5510 is a good buy for a room up to 392 sq ft: AHAM certifies 253 CFM of smoke clearing. The 5520 and 5530 have exactly the same certified numbers and use the same Filter Q, so buy whichever is cheapest the day you shop. On October 17, 2026 the 5510 and 5520 were $179.99 and the 5530 $219.99 at Amazon.com. The AT40 ($185.64) draws 45 W instead of 65 W and ships with two years of filters, so it costs about $108 less over two years.

Is the Winix 5510 ENERGY STAR?
No. AHAM lists it as not ENERGY STAR; it draws 65 W on the smoke setting. The AT40 and T810 are ENERGY STAR at 45 W.
How big a room does the Winix 5510 cover?
AHAM suggests it for a room up to 392 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 5510?
Its AHAM Clean Air Delivery Rate is 252 for dust, 253 for smoke and 247 for pollen, with a PM2.5 CADR of 252. CADR is cubic feet of clean air delivered per minute — higher clears a room faster.
Does the Winix 5510 use a real HEPA filter?
Its filter is listed as True HEPA (H13) + activated carbon. True HEPA captures 99.97% of particles down to 0.3 microns. The activated-carbon layer also helps with odors and gases.
How much power does the Winix 5510 use?
About 65 watts on its smoke-clearing setting, which works out to 3.9 CADR per watt — a measure of how much clean air you get for the electricity it draws. It is not ENERGY STAR certified.
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.
