Good Non Woven Hepa Filter Media

What material is used for HEPA filters?

    The Hepa filter material is the heart of the biological safety cabinet, consisting of randomly arranged fiber mats. A Hepa filter is a disposable dry Hepa filter. It is made of laminated borosilicate microfibers, and the key metrics that affect action are fiber density and diameter and filter thickness. A Hepa filter may remove at least 97.00 % airborne particles. Particles of this size are the most difficult to filter and thus are considered the most permeable particle size.

    Hepa filter media are mainly composed of ultra - fine polypropylene fiber filter paper or glass fiber filter paper, non woven fabric, hot melt adhesive, sealant, outer frame material, etc. Hepa is divided into five materials: PP filter paper, glass fiber, composite PP PET filter paper, melt - blown polyester non woven fabric and melt - blown glass fiber. Although the materials are different, they all have one thing in common: large wind resistance, large dust holding capacity, and high filtration accuracy.

    Hepa filter cloth is mainly used in the air purifier industry. The filter cloth material has good hardness and sweetness, and is suitable for the composite bottom of various filter materials. The high tensile strength makes the composite material have higher tensile properties, tear resistance and burst resistance, which greatly improves the service life of the product. The Hepa filter fabric can effectively absorb various harmful gases.
