Why Do You Need HEPA Filters In Cleanrooms?

We tend to debate often on various aspects of air pollution in the outdoor premises. But with the arrival of COVID, we have started taking care of air inside the indoor spaces. This situation had become a boon for air purifiers and air filter manufacturers, especially for HEPA air filters.

What is a HEPA filter?

HEPA stands for high efficiency particulate air. It belongs to a type of pleated mechanical air filter. This type of air filter has the efficiency of 99.999% (99.95% for H13 & 99.995% for H14) of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns (µm).

Cleanroom provides a clean environment to manufacture microchips, semiconductors, data centers, liquid crystal display screens, pharmaceuticals, and in-hospital operating rooms. For this purpose, cleanrooms end users will have to install air filters i.e., HEPA filters to control the airborne particles.

Let me explore high efficiency air filters offered by American Air Filter (AAF) for the cleanrooms.

AAF Products (HEPA Filters):

AstroCel® I:

AstroCel I HEPA filters are used primarily in cleanrooms and clean zones, which require the very highest levels of contamination control. The filter consists of water-proofed, fire-retardant fiberglass media formed into a series of pleats.

AstroCel® II:

AstroCel II filter media is made from sub-micron glass fibers formed into a high-density paper. Glass filament separators are used to form the media into mini-pleat panels that withstand high-velocity airflow.


Designed specifically for the unique requirements and challenges of the pharmaceutical industry. MEGAcel filter has proven durability, polyalphaolefin (PAO) compatibility, high particulate filtration efficiency, and the lowest pressure drop to meet the demands of pharmaceutical manufacturing.
