Air Purifier Comparison

Our goal is to ensure the air quality in your home or work space is healthy. To reiterate that commitment to pollutant-free living, we have provided this easy to read comparison chart, that compares Oransi’s leading HEPA air purifiers to top-rated models from competitors. Every product listed falls within the range of air purifiers that remove common airborne allergens.  Lower range air purifiers tend to fall below the $250 retail price and work best for dust.
See the Education Center for air purifier recommendations for allergies, mold, pets and smoke.
