The advantages of HEPA air purifiers: The electrostatic HEPA filter traps airborne particles through electrostatic forces and therefore does not clog. Air purifiers with HEPA filter systems can also purify larger amounts of air. HEPA filters can capture much smaller particles than mesh filters. HEPA filters remove a variety of pollutants and allergens from the air, ensuring significantly better indoor air quality. This can even relieve symptoms of allergies and asthma. HEPA filters typically have a longer lifespan than other filters and are therefore more cost-effective in the long run. he HEPA filters of some of our air purifier brands have a lifespan of 5 to 10 years.
