Save $100: The Windmill three-in-one air purifier can now save you $100 and stress from poor air quality, as it’s available at a discounted price of $299. Whether you’re dealing with wildfire smoke or allergies, this CNET-favorite air purifier is at its lowest price of the year.
Originally priced at $399, the Windmill three-in-one is now available for 25% less. Based on Keepa’s price history, this is a notable drop from the product’s 90-day average price of $335. Note that only the white and navy colors are discounted. The bamboo color is still available at the listed $399 price.
The Windmill three-in-one was lab-tested and earned a spot in CNET’s list of best air purifiers for 2026. According to our in-house experts, this purifier with a HEPA filter is fabulous for “bedroom, home office and nursery use. It’ll work best on allergens and smoke residue, as it filters fine particles as small as 0.3 micrometers.” So, basically, it’s a savior if you’re near the wildfires or pollution, and if you’ve kids or someone with allergies at home.
This device inhales dust, not extra watts. According to CNET experts Ajay Kumar and Gianmarco Chumbe, it’s energy-efficient and delivers “generally quiet performance, with an average of 43.87 dBA.” It also auto-adjusts based on your AQI. And if you’re too comfy to get up, just use the app to set schedules and enable additional features like Child Lock and more.
But the experts also mentioned that despite its strong performance in removing fine particles, “the Windmill doesn’t impress overall at removing particles. The T90 of 2 minutes and 13 seconds puts it behind the Shark HP232.” For a more balanced performance across all categories, they liked the Blueair Pure 311i Max.
