20x22x1 High MERV Air Filter for Asthma – Breathe Easier Today

After building and testing thousands of air filters in our U.S. facilities, we’ve seen firsthand how the right filter can transform a home for asthma sufferers. Our 20x22x1 high-MERV air filter isn’t just designed to meet industry standards—it’s engineered to exceed them. Using the same filtration technology trusted in hospitals and labs, it captures the fine airborne particles most likely to trigger asthma attacks. The result? Noticeably cleaner, easier-to-breathe air that helps your family feel better day after day.

The 20x22x1 high MERV air filter from Filterbuy is a device that is very effective in capturing microscopic pollutants that a normal filter cannot. It is the main cause of minor health problems, such as asthma attacks, to what is most commonly floating in the household air. These microscopic pollutants include fine dust, pet dander, pollen, mold spores, and smoke particles. 

Made in America with high-efficiency pleated materials, this filter not only makes the air cleaner but also keeps your HVAC system safe from deposits and overwork. We test that a high-MERV filter that is properly installed can greatly lessen the air-borne irritants, which in turn would make the breathing environment more comfortable for people with asthma and allergies. People who suffer from asthma should change a high-MERV filter with a Filterbuy one, and they will notice the difference in their air and even their health almost at once. 

"After years of manufacturing and testing filters in real homes, we’ve seen how a properly fitted high-MERV filter can be life-changing for people with asthma. It’s not just about cleaner air—it’s about creating a space where breathing feels effortless again."
