High efficiency particulate air filter, or HEPA, can achieve filtration efficiencies of more than 99.97% for 0.1 μm and 0.3 μm. Air can pass through, but fine particles cannot, often in places where there is a high demand for clean air.
The mini-pleated HEPA filter adopts ultra-fine glass fiber or high-performance chemical fiber as media, the spacer is hot melt adhesive, the new polyurethane sealant sealant, the aluminum alloy profile, galvanized steel plate, aluminum plate as frame, each of which has passed strict scanning leak detection test before delivery.
