Although the Winix AM90 is white and the Winix AM80 is charcoal gray, this is a personal choice and doesn’t impact the overall use. They are both 15.1 x 8.7 x 23.5 inches and weigh 16.5 pounds. The controls are on the top of the air purifiers, and they have a mesh cover on the front.

Pros and Cons

Because the Winix AM90 and the Winix AM80 are so similar, the pros and cons will highlight any other differences.

Winix AM90


  • Quiet enough to have by the bed
  • Impressive results with air quality
  • Simple use on auto mode or with app


  • We thought the carbon filter would be thicker

Winix AM80


  • It’s quieter, even on medium fan speed
  • Excellent cleaning abilities, especially with dust
  • Reduced allergy symptoms


  • The only way to control it is with the buttons on the unit

The Final Verdict

Although there were only a couple of differences, they had quite a significant impact. At first, it was disappointing to see that the Winix AM80 had neither Wi-Fi nor a remote control, but the best way to run both of these air purifiers is on Auto Mode and so they take care of themselves. The winner today is the Winix AM80. The color for us was nice but more importantly, it does a better job at purifying air, and it is quieter.
