HEPA (High-Efficiency Particulate Air) filter is a type of air filter that can trap a high percentage of very small particles, making it highly effective for improving indoor air quality.

Key Characteristics:

1. Efficiency: HEPA filters must capture at least 99.97% of particles that are 0.3 microns in size, including dust, pollen, pet dander, smoke, and some bacteria.

2. Construction: Made from a mat of randomly arranged fibers, often composed of fiberglass, HEPA filters create a dense structure that traps particles as air passes through.

3. Applications: Commonly used in air purifiers, vacuum cleaners, and HVAC systems, HEPA filters are also essential in medical facilities and clean rooms to maintain sterile environments.

4. Maintenance: HEPA filters need to be replaced regularly to ensure optimal performance, as they can become clogged with trapped particles.

5. Health Benefits: By reducing airborne allergens and pollutants, HEPA filters can help alleviate allergies, asthma, and other respiratory conditions.

Overall, HEPA filters are a popular choice for anyone looking to enhance air quality in homes or workplaces. more:https://www.wiforfilter.com/HEPA-air-filter/
