Are Air Purifiers Effective for Eliminating Allergens?

Are Air Purifiers Effective for Eliminating Allergens? Whether you're an allergy or asthma sufferer, or someone who is concerned with providing your family with the best indoor air quality, finding a solution to the airborne contaminants in your home is a very important issue. The Environmental Protection Agency (EPA) determined that most indoor air is three to five times dirtier than outdoor air. This startling revelation led to a boom in the production of air purifiers, but do they really work?

Most air purifiers remove airborne pollutants like mold spores, pollen, dust, bacteria, and pet dander. But determining whether an air purifier is effective is measured by its ability to capture particles and the amount of air it can process in a given time. Translation: If an air purifier can't catch particles of all sizes and process enough air to make a difference, it's probably not worth the cost of shipping.



To qualify as a true HEPA filter, the filter must remove at least 99.97% of airborne contaminants, including mold spores, dust, pollen, smoke, and pet dander. There are many generic HEPA filters on the market today; however, true HEPA filters are marked as such on their packaging and provide the most efficient filtration.


Rating air purifiers is simple: the higher the CADR rating, the less time the unit needs to remove a given quantity of certain particles from the specified size room. The room size is indicated on the packaging of the air purifier and all AHAM-certified models are marked with CADR data, as this information acts to distinguish each air purifier from its competitor. You can use the CADR ratings to determine which air purifier works best in your home.

As you can see, there are many standards and ratings requirements used for all air purifiers. These requirements are used to ensure that every consumer receives the benefits they've been guaranteed by the manufacturer. Air purifiers can't guarantee the elimination of allergies or asthma. However, HEPA air purifiers can guarantee the elimination of harmful airborne contaminants.
