HEPA stands for High Efficiency Particulate Air (filter). HEPA air filters can help capture 99.97% of airborne particles. They are most common in medical environments. You may also find HEPA filters in air purifiers and vacuum cleaners.
A HEPA filter can restrict airflow more than an HVAC air filter, and might not be compatible with your residential HVAC system.
MERV stands for Minimum Efficiency Reporting Value. A MERV rating tells you about an HVAC air filter’s ability to capture particles between .3 and 10 microns. HVAC filters generally have a MERV rating between 8 and 13. The higher the number, the more effective the filter is at trapping pollutants and allergens. A MERV rating above 16 is rated as HEPA performance.
If you’re concerned about indoor air quality, consult with your American Standard dealer for product recommendations including air filters and whole-house air purification systems.
Air cleaners reduce the total volume of allergens, dust, pollen, dander, and other harmful particles from the newly cooled or heated air circulating in your home.
Air filtration systems utilize an air filter to remove harmful particles from the air you breathe. In most air filtration systems, you can change and maintain filters on your own.
