Primary filter and air conditioner filter are consumables. Before 1984, China did not develop many filter elements. But today, as materials continue to grow and people demand it, filters are becoming a necessity. The relationship between primary filter and air conditioning filter and the need for air purification indicate that people are paying more and more attention to life and living environment.
Air quality has become an issue of increasing concern. How to purify the air and create a suitable air environment for people is the current research direction of the filtration and purification industry. Surface filtration and deep filtration are used for filtration (surface filtration is to intercept impurities outside the filter material, deep filtration is the labyrinth structure, leaving impurities in the filter material). The filter materials are metal mesh and nylon. Net, chemical fiber filter, paper filter, activated carbon, etc. How to choose the right filter in the right environment will be the topic we are going to explore today.
This classification method is official. Our country has issued the relevant standard GB/T 14295-93 Air Filter and GB/T 13554-92 HEPA Air Filter.
Through the above, it can be found that the system uses hierarchical filtering. For a variety of situations from different working environments, buyers should select the corresponding precision filter in combination with the working environment and industry requirements to achieve air cleanliness requirements.
