Both HEPA melt-blown and melt-blown fabrics are non-woven fabrics made by PP resins, but compared with other melt-blown nonwoven fabric, HEPA water electret melt-blown nonwoven fabric delivers water to the nozzle and sprays high-pressure to the melt-blown, HEPA can effectively remove at least 99% of aerosols 0.3 micrometers (μm) in diameter, also prevent and remove the spread of dust, pollen, PM 2.5, and particles that are more than or equal to 0.3 μm, and HEPA adopts a low drop pressure design, which makes the air easier to circulate and breathe easily.
