HEPA Filter uses in Pharmaceutical manufacturing

The term HEPA means “High-efficiency Particulate Air,” sometimes called “High-Efficiency Particulate Arrestance,.” and what that basically means is that it’s a special kind of filter that captures microscopic particles. HEPA Filter removes particles like dirt, pollen, spores, pet dander, bacteria, smoke, and particulate that comes from out of doors pollution.

Types of HEPA Filters?

Another issue concerning HEPA filters is that they are available in varieties.

As a True HEPAHEPA-type, or simply plain recent HEPA filter. But the variations between them are big. Essentially, a true HEPA filter is that the best kind as a result of its certification to capture 99.97% of particles all the way down to 0.3 microns in size. True HEPA is more efficient than HEPA Types.

The efficiency of HEPA Filters?

High-efficiency particulate air is able to filter 0.3-micron size particles. Its efficiency range is 99.97%. The name suggests, HEPA air cleaners are devices that clean the air by removing microscopic contaminants. The only downside to HEPA filters is that they can’t capture viruses, odors, or chemical gases.

For example: if a return air contains 10,000 particles per ft³ and passes through these filters, then it passes only three particles out of 10,000 particles. Those particles are either too tiny or need another reasonable filter to capture them.

On the opposite hand, filters labeled as HEPA-like, HEPA-type, or HEPA will solely capture particles.

Uses of High-efficiency particulate air Filter?

The HEPA filter is used to protect the drug products from air pollutants or air-borne particles; by using it, product quality can be maintained. Its use is typically in pharmaceuticals, FMCG, military, biologicals labs, nuclear labs, and medicals facilities. High-efficiency particulate air Filter is safe for use because of its release very fewer amount fibers in the air, so overall, no effects on the human’s body.

MOC of HEPA Filters?

HEPA Filters are made of borosilicate glass fibers or sheets of plastic fibers (e.g., polypropylene). Ceramic glass fiber is used in case of the hot zone or Depyrogenetic conditions. they are easy to wash. Wash the filters with purified water followed by dry them with air.

How does HEPA Filter Works?

HEPA filters work in Four ways:

Direct impaction: Large particles stuck inside the fibers after a collision.

Sieving: Large particles shucks between the fibers.

Interception and diffusion: Due to Airflow, the small and medium particles rotate around the fibers and shucks inside them.
