WindmillInternally, like most purifiers, the Windmill packs in a pre-filter for capturing hair and dust, an activated carbon filter for odors and VOCs, and finally, a True HEPA filter to block 99.97% of airborne pollutants.
In addition to good looks and layers of filtration, the Windmill Air Purifier offers a bevy of running modes and smart features, similar to other more advanced machines on the market. Users can choose between three fan speeds, boost and eco modes. They can also use an app to see room air quality, check in on the filter’s lifespan, turn button beeps off or on, and even schedule certain modes to kick on or off, which seems particularly useful for sleeping.
There are two sleep modes on the machine. Whisper lowers noise output to just 16 dB, while white noise ramps things up to a random noise-drowning hum of 47 dBs, which is supposedly research-backed for better sleep. Unlike many other purifiers, which ask you to choose between keeping the device’s LED button lights lit, off, or covered, Windmill’s unit offers an auto fading mode that’ll turn lights off after 3 seconds. You can, of course, adjust the setting to keep them on or totally off.
But is it worth the price?

he Windmill Air Purifier looks like a well-rounded package with outstanding aesthetic details. But at $459, it’s also very expensive for what it is.
