Many allergens, including pet dander and dust mite allergen, are prone to become airborne. Effective air cleaning devices are part of a multi-faceted approach to allergen reduction. In order for an air cleaner to earn Certification, strict standards for appropriate levels must be met when:

• Reducing allergens from the air
• Monitoring allergen levels after use to ensure reduction of allergens is a result of removal, not just redistribution
• Monitoring ozone levels to ensure they remain within the Code of Federal Regulations Guidelines.
