What Are The Materials Of HEPA Filter Media?

What are the raw materials of HEPA filter media? What are the commonly used materials of Filter Cotton? We will introduce several types of commonly used HEPA air filter cotton raw materials. We generally divide it into three categories:

1. synthetic fiber filter cotton:

Synthetic fiber filter cotton is a new type of filter material with low resistance, light weight, large capacity, environmental protection ( can be incinerated ) and high cost performance. Using polyester fiber as the main raw material, it has good corrosion resistance and can resist acid and alkali to a certain extent.

2. non woven filter fabric:

Non woven filter fabric is one of the materials with relatively mature technology and stable performance. Using meltblown filter fabric, acupuncture, spunbond etc. As processes, it is made through multiple processes to produce large dust holding capacity, strong moisture resistance, relatively long service life economical and durable. Non woven filter fabrics are also the raw materials for earlier air filter media. In recent years, due to the recent improvement of technology,the emergence of composite non woven fabrics have greatly improved its filtration performance and it have been widely used in places with relatively high requirements for dry air cleanliness.

3. glass fiber filter cotton:

Glass fiber filter cotton is mainly made of glass fibers of various thicknesses and lengths through a special process. Glass fiber with its stable performance, high temperature resistance, high efficiency, large capacity and long service life are among the best in the industry and favored in some special places. However, the transportation of glass fiber requires special care, and its price is relatively expensive. Household air filtration products can choose cost - effective filtration products.

Customers have different requirements for the air cleanliness of the place of use, so they need to choose different levels of air filters with different cost performance. While taking into account the filtration efficiency, it is also necessary to comprehensively consider issues such as the cost of subsequent replacement of the air filter and the stability of the filter screen. It is hoped that the above answer will help you.
