Use the Right Panel Filter for you Application
HEPA and 95% DOP panel filters dramatically improve the quality of air, but each are designed to meet different application requirements. Here are some guidelines to help you select which panel filter will best meet your needs.
| Higher filtration efficiency: 99.97% on 0.3 micron particles (emits three-0.3 micron particles per 10,000 particles) |
95% on 0.3 micron particles (emits 500-0.3 micron particles per 10,000 particles |
| Exhaust airstream is near breathing zone |
Heavy loading applications |
| Lighter loading applications |
Exhaust airstream is not near breathing zone |
| Visible emissions are unacceptable |

In heavy smoke applications, a combination of 95% DOP and HEPA panel filters may be the best solution. 95% DOP filters last 3-5 times longer and have greater holding capacity in oil loading applications.
