1. Residential air purification: HEPA filters are the core component of home air purifiers, effectively capturing dust, pollen, mold spores and other particulates to improve indoor air quality.
2. Medical and healthcare: HEPA filters are widely used in hospital operating rooms, isolation wards and other clean areas to ensure a high standard of clean air environment.
3. Cleanroom applications: Industries such as electronics manufacturing, pharmaceuticals, and aerospace have stringent clean air requirements, and HEPA filters are essential equipment in their cleanrooms.
4. Industrial dust collection: In industries like chemicals, metallurgy, and mining that generate large amounts of industrial dust, HEPA filters can effectively capture these particulates to protect the work environment and equipment.
5. Household vacuum cleaners: High-end vacuum cleaners are often equipped with HEPA filters, which can effectively prevent the filtered dust from being re-dispersed into the indoor air.
6. Automotive HVAC systems: Automotive air conditioning systems are fitted with HEPA filters to remove particulate matter from the cabin air.
