Definition
True HEPA (High-Efficiency Particulate Air) is a recognized filter standard. To qualify as True HEPA, a filter must capture 99.97% of airborne particles that are 0.3 microns in diameter. This includes common allergens like pollen, dust mites, pet dander, and mold spores, as well as some bacteria and viruses. Some filters may be 'HEPA-type' but do not meet this strict standard.
Why It Matters
A True HEPA filter provides superior removal of microscopic allergens and pollutants, making it essential for allergy sufferers and anyone seeking cleaner indoor air quality.
