About Winix
Winix is a South Korean home-appliance manufacturer founded in 1973, with Winix America headquartered in the Chicago area and manufacturing operations spread across South Korea, China, and Thailand. The company's catalog runs well beyond the air purifier it's best known for in the US market, extending into humidifiers, dehumidifiers, water filtration and drinking-water systems, ceramic heaters, and garment-care appliances, all built around the same core focus on indoor air and water quality it has pursued for more than five decades.
Winix's air purifiers have drawn sustained third-party attention: the 5500-2, the model our featured 5510 directly succeeds, was a Wirecutter top pick for multiple years running, and Consumer Reports has independently tested a wide range of Winix models, from the compact A231 up through the large-room 9800. In our own testing, the 5510 carries that established filtration platform forward with an added dedicated VOC and gas sensor plus WiFi app control, and it sits on a review base numbering in the tens of thousands on Amazon.

Winix products we rated highly
Winix 5510
A top pick in our testing for VOC and chemical-odor control: the 5510 pairs a dedicated gas sensor with 99.99 percent particle capture down to 0.01 microns, finer than the 0.3-micron threshold that defines standard HEPA filtration.
