After treatment with special components, the humidifying filter net forms a corrugated cross-linked hydrophilic polymer composite material, which has excellent water absorption, good self-cleaning ability, and is non-toxic, acid and alkali resistant, mildew resistant, and corrosion resistant. Humidifiers equipped with pure type humidifying filter nets are also known as direct evaporative humidifiers. The pure humidifying filter net humidifies the air while washing the air with purified water, effectively removing pollutants from the air, killing bacteria, purifying the air, promoting indoor air circulation, and ensuring human health to a greater extent. The humidifying filter net technology is unique and practical, and is widely used in commercial humidifiers, central air conditioning, household air conditioning, small humidifiers, industrial humidifiers, etc., thus creating a pleasant space for people’s work and life. Humidifying and cleaning – no white powder produced, high efficiency – has high humidifying efficiency, multi-effect – has multiple effects such as humidifying, cooling, and air exchange, long life – can be washed with water, long service life. Specifications: Technical parameters: Water absorption speed: longitudinal (MD) ≥110mm/min, transverse (CD) ≥110mm/min, water absorption capacity: ≥360g/m2.
