HEPA filters are designed to effectively trap very fine particles, but they don't filter out gas and odor molecules. Activated carbon (charcoal) or other types of filters are required to replace or supplement HEPA filters in situations where filtering of VOCs, chemical vapors or odors from cigarette

As one of the essential raw materials for industrial textiles, non-woven fabrics are widely used in medical and health care, filtration/separation, earthwork/building construction, automobiles and other industries. Special features and functional structure and efficient production process. In recent

Melt-blowing (melt-blowing) is to blow the melt extruded by the screw with a high-speed and high-temperature airflow, so that the thin stream of the melt is stretched at a higher magnification to form ultra-fine short fibers.

A HEPA filter is a high efficiency air particulate air filter that can capture ultrafine pollutants. HEPA filters are considered the industry standard for removing dust, pollen, mold, bacteria, particulate matter, and other airborne particles.
