Description
HEPA (High Efficiency Particulate Air) can achieve a filtration efficiency of up to 99.97% for micro seats larger than 0.3 microns, making it an excellent air purification product. HEPA is divided into five materials: PP filter paper, glass fiber, composite PP+PET filter paper, meltblown+activated carbon+non-woven fabric, and meltblown+TPP formaldehyde particles+non-woven fabric.
Characteristic
Small wind resistance, high dust holding capacity, and high filtration accuracy. It can be processed into various sizes and shapes according to customer needs, suitable for different machine models.
Purpose
HEPA is widely used in air purifiers, central air conditioning, clean rooms, and other fields to remove dust and pollen.
