What is HEPA?Updated 4 months ago

HEPA stands for High-Efficiency Particulate Air. It’s a type of filter that is designed to trap very small particles that regular filters can’t capture. A True HEPA filter, like the one in the Windmill 3-in-1 Filter, can remove 99.97% of particles as tiny as 0.3 microns, including dust, pollen, pet dander, mold, and even some bacteria and viruses. This makes HEPA filters one of the most effective ways to clean the air in your home. The U.S. Department of Energy sets strict standards for HEPA filters, ensuring they meet this high level of filtration efficiency.
