FAQs

What makes Windmill purifiers different from other purifiers?
The Windmill Purifier is the first ever air purifier made with a real bamboo finish. It also comes in a sleek white or bold navy, so you can easily match your home aesthetic and vibe. Windmill's advanced laser-based air quality sensor and 3-in-1 Medical-Grade HEPA Filter helps capture 99.97% of airborne particles down to .3 microns (and 99% of airborne particles down to .1 microns). The purifier is ultra-quiet (starting at 16 dBs), efficient (Energy Star certified and AHAM Verifide), powerful (cleans any space up to 1,950 sq. ft.), and super smart (from the Windmill Air app, monitor your PM2.5/Air Quality Index, set schedules, turn noise on/off, turn lights on/off, and more!).
Does the Windmill purifier require a wifi connection to operate?
Can the Windmill purifiers filter out smells and odors?

What filters do I need to use with the Windmill puriifer?
Why do I need a purifier?
According to the Environmental Protection Agency (EPA), indoor air can be 2-5 times more polluted than outdoor air, making air purification an important step for maintaining cleaner air indoors. An air purifier can significantly improve indoor air quality by removing pollutants, allergens, and harmful particles from the air. Even in seemingly clean environments, invisible contaminants such as dust, pollen, pet dander, mold spores, and volatile organic compounds (VOCs) can build up over time. Purifiers are especially useful for people with allergies, asthma, or other respiratory conditions, as they help reduce triggers for these issues. And, they can neutralize unpleasant odors and reduce exposure to bacteria and viruses, contributing to a healthier living space overall.
