HEPA filter with separator are called as pleated HEPA filter, another is mini pleated HEPA filter, which separated with wirelike separator instead of ordinary separator.

1. Choose the necessary air filter
Different company has different requirement for air cleanliness, we suggest to choose the primary efficiency air filter or medium efficiency air filters according the efficiency of terminal HEPA filter, if the previous filter efficiency is quite different with the next one, then the previous filter can’t protect the next one.
Generally speaking, we suggest to install a air filter every 2-4 sections, for example, install like G2-F5-H8.

2. Filter media area should be as large as possible
Larger filter media will make the pre filter/secondary filter a longer life, 50% increased in filter media area may 70%-80% prolong the pre filter/secondary filter under the certain final resistance. The larger the filter media area, the higher dust holding capacity and lower resistance.
