Winix and Coway are major players in the air purifier market, with exceptional products that are difficult to match.
In this article, I will compare the Winix C535 and the Coway AP-1512HH, two mid-sized air purifiers intended for rooms of up to 360 sq. ft. (the Coway covers rooms of up to 361 sq. ft., to be more precise).
These air purifiers utilize a four-stage filtration technology, which includes three primary filtration layers and an optional filtration stage, an ionizer. On the Winix, this stage is known as PlasmaWave, while the Coway uses the term Ionizer.
The build quality, size, and specifications of both air purifiers are nearly identical. They feature controls on the top, an air quality sensor, and an air quality indicator, as well as an auto mode.
One advantage of the Winix is its remote controller, though it would be even better if both models could be connected to a smart app.

Which One Does It Better?
Before deciding on the winner, I want to say that the Winix C535 and the Coway AP-1512HH are one of the best air purifiers I have tested so far, and you can’t go wrong with either one.
But, which air purifier is better? While both the Winix C535 and the Coway AP-1512HH are top-tier air purifiers, the Coway has a slight edge, in my opinion. It performed slightly better in performance tests, is quieter, has an ECO mode, and its air quality sensor can detect PM2.5 particles, unlike the Winix, which only senses odors.
