Air cleaners, also known as air purifiers or air sanitizers, can improve your home’s indoor air quality. Air cleaners can help reduce indoor air pollution by removing very small particles from the air.
Indoor air is full of asthma and allergy triggers like dust mites, pet dander, volatile organic compounds (VOCs), odors, and even pollen and air pollution from outside.
For an air cleaner to be CERTIFIED asthma & asthma & allergy friendly®, it must meet the following standards for air cleaners:
- It must reduce allergen levels in the air. We test air cleaners in an environmentally controlled chamber, and we use different types of allergens like grass pollen, cat dander, and dust mite allergen. This is because allergens have different sizes and behave in different ways; we want to make sure the air cleaner can cope with a range of allergens.
- It does not reintroduce allergens back into the air. This means that the allergen should be captured on the filter of the air cleaner and not redistributed into the air.
- Some appliances produce ozone as a by-product. The Code of Federal Regulations sets a limit on this of 0.1mg/m3, and we only certify air cleaners that have met this standard.
