Tech Resource (PDF) HEPA and ULPA Particle Filters
These filters remove sub-micron particles, which are too small to see but create BIG problems in many critical manufacturing operations.
Tech Resource (PDF) Charcoal Filter Life
Unlike HEPA and ULPA particle filters, activated charcoal filters create no additional backpressure when they near the end of their service life. So when do you replace them? Here's how to tell.
