Winix 5510
Air purifiers — mid-size True HEPA with app and PlasmaWave · Reviewed by Katie · amazon.com live, Sept 28 2026
Why it scored a 82
At $134.99 the Winix 5510 is the Wi-Fi successor to the discontinued 5500-2, a mid-size True HEPA purifier with the heaviest carbon load in its tier. Reliability leads at 94 and Satisfaction at 92: it keeps the 252 CFM AHAM CADR and 226-gram carbon filter, adds an app, and lets you switch off the PlasmaWave ionizer. Quality sits at 76 because turbo hits 67 dBA, the loudest here, quiet-speed CADR trails Coway and Levoit, and the app is basic; the 2-year warranty holds Warranty at 66. It is for a kitchen-adjacent living room where cooking and pet odors matter as much as dust.

Should you buy the Winix 5510?
The Winix 5510 is for a kitchen-adjacent living space or a home with a litter box, where odors matter as much as dust. Its filter set carries 226 g of activated carbon, far more than the thin carbon layers on most mid-size units, and the True HEPA layer handles particles. It ranks fourth of ten in our air purifier group at $134.99. It is not the pick for a bedroom, because turbo is the loudest in this group; for a quiet room look at the Blueair 311i Max.
Where it earns its score
- Real carbon for real odors. 226 g of activated carbon is why this unit clears cooking and pet smells that other mid-size purifiers only mask.
- Solid particle performance. AHAM CADR of 252 CFM for PM2.5 and 372 sq ft at 5 air changes per hour.
- Sensors plus a switchable ionizer. Light and particle sensors drive auto mode, sleep mode and a timer, and PlasmaWave can be turned off entirely.
- Low upkeep. A washable pre-filter catches the big stuff, and the HEPA and carbon set lasts 12 months.
What to know first
- Turbo is loud. Measured at 67.2 dBA, the loudest top speed in this group. Sleep mode at 35.2 dBA is fine; plan on auto mode most of the time.
- The filter set is pricier. $79.99 per year, though the 12-month life keeps annual cost in line with cheaper filters replaced twice.
- Warranty is the weakest ViperScore factor. Two years is standard for this class.
- The app is basic. Winix Smart covers the essentials with Alexa and Google, but it is not as polished as Levoit's or Blueair's.
Our verdict
The Winix 5510 scores 82, a Good Buy, and it is the one to buy if smells are your main reason for shopping. If odors are a minor concern and you want a quieter top speed with a cheaper filter, the Levoit Core 400S scores three points higher for $10 more.
