The Best Filter for Asthma: What You Need to Know

Replacement filters for air purifiers are essential for those who suffer from asthma and allergies. The Asthma and Allergy Foundation of America (AAFA) recommends air purifiers with certified filters that can remove almost 98% of allergenic particles from the air. The Environmental Working Group (EWG) suggests using a filter that replaces the volume of air in a room two or three times every hour. When it comes to selecting the best filter for asthma, it is important to consider the Minimum Efficiency Rating Value (MERV).

MERV ratings are numbers assigned to air filters to determine their efficiency in removing particles from the air. For those with severe allergies or asthma, it is recommended to install filters with higher MERV ratings in their home. One of the top-rated filters for asthma is the Filtrete Ultra Allergen Healthy Living 1500 Air Filter. This purifier has a six-stage HEPA filtration system, including filters that eliminate odors and a carbon-based activated carbon filter.

The Blue Pure 311 Auto particulate filter works identically to any other True HEPA filter on the market. The Honeywell HRF-ARVP300 HEPA prefilter combo pack is another great option for those with asthma. This filter has a 26% efficiency rating and is designed to work together with the carbon filter on your Rabbit Air A3. Levoit also offers a high-end air purifier at a low cost, with a high-power fan and a HEPA H13 True filter. This technology has been proven to be one of the most reliable in the world for filtering all contaminants and improving the quality of fresh air in homes.

Winix continues to uphold the tradition of combining all types of air filters into an all-in-one air filter. Its True HEPA filter captures 99.97 percent of allergens, virus particles, pollen, mold and fungal particles as small as 0.3 millimeters. Finally, HepaSilent is the most sophisticated air filtering technology available right now. Thanks to its dual prefilters, it can last 12 to 18 months, which is longer than standard True HEPA filters.
