How HEPA Filters Effectively Capture Ultrafine Particles in the AirHEPA (High Efficiency Particulate Air) filters are widely recognized for their ability to capture ultrafine particles in the air, making them essential for improving indoor air quality. 

A HEPA (High Efficiency Particulate Air) filter is a powerful air filter that can capture and trap microscopic particles like dust, pollen, mold spores, pet dander, bacteria, and viruses. It is designed to remove at least 99.97% of particles that are 0.3 microns or larger. HEPA filters work by forcing air through a fine mesh of fibers, using mechanisms like interception, impaction, and diffusion to trap particles. These filters are commonly found in HVAC systems, air purifiers, and vacuum cleaners to improve indoor air quality, especially for those with allergies or respiratory conditions. By removing harmful particles from the air, HEPA filters contribute to cleaner indoor spaces and better respiratory health.
