Check it out now and can choose the right HEPA air filter for your needs.

What Are HEPA Air Filters?

HEPA is an air filter that potentially eliminates 99.97% of bacteria, dust, pollen, and molds. It is used for heating, air conditioning, and ventilating as well.

High-Efficiency Particulate Air or HEPA is a pleated mechanical air filter that removes 0.21 microns.

It is a non-chemical product secured while filtering.

Standard HEPA Air Filters

Users are widely used standards HEPA air Filters such as:

H11- captures PM2.5, dust, small particles, and viruses. Excellent key to clean air.

H12- Tightly constructed making a composite surface for allergens and particles.

It efficiently traps 0.3 microns particles applicable for various applications.

Which HEPA Air Filters Commonly Used?

HEPA air filters are widely used for different establishments and public facilities because of the excellent particulate retention rate suitable for air purification applications. Here are some HEPA air filters applications:

  • Airplane cabins
  • Semi-Conductor Fabrication Plants
  • Pharmaceutical Plants
  • Hospitals
  • Homes

What Materials Does HEPA Air Filters Made of?

HEPA air filters are safe to use because of the verified material used.

  • Non-woven fabric (Polypropylene)- it allows and provides excellent air filtration
  • Fiberglass- provides high performance for HEPA filters
  • Vegetal- Made from vegetable fibers
  • Synthetic Fibers- Specialized centered metals for industrial applications.
  • Animal hair- Effective longevity trapped even large particles.
  • Synthetic foams- or Polyurethane foam elements for unwanted air contaminants.
  • Coarse glass- High efficiency constructed from wet-lead featuring different capabilities.

HEPA Air Filter MAde

It is tangles and compressed together to make a sheet that is usually pleated for surface improvement.

HEPA Air filters are fibrous. It is widely made of fine glass fibers.

It has less than 1-micron diameters which glass threads are compressed to make a filter mat. It has 2,500 layers of glass threads.

How Does HEPA Air Filter Works?

The high-density filter fibers catch impurities that pass through in Direct Impaction, Diffusion, Sieving, and Interception when air is drawn towards the HEPA filter. When particles go straight, collide, and become trapped with fiber, this is known as direct impact. It has the same work but different performance. It works when compressed tightly to and stops small particles get through.

There are four different ways that HEPA air filters do when trapping contaminants. The following are:

  1. Direct impaction: it stuck or stick to the fibers sheets when it collides.
  2. Sieving: trapped between two fibers
  3. Interception- occurs and stick to the fiber when moving through.
  4. Diffusion: small particles get stuck around the fibers because of airflow.

HEPA Air Filter Works

Here are some particles examples that HEPA air filters can absorb:

  • 0005 microns pure oxygen
  • 3- 60 microns bacteria
  • 1-10 microns dust mites
  • 1-150 microns car emissions
  • 3- 12 microns molds
  • 3-40 microns spores

Does HEPA Air Filters Are FDA Approved for Corona Virus?

HEPA air filters can perfectly absorb particles that effectively capture 0.3 microns in diameter.

However, FDA approves the air purifier as an effective device to prevent coronavirus.

Engineering can’t show the answer if HEPA air filters are suitable for coronavirus prevention.

What is HEPA-Type?


A HEPA-type air filter is less effective than a True HEPA filter. It is gaining popularity in the field of air purifiers due to its inexpensive cost and comparable efficiency.

A HEPA-type filter captures particles as fine as 2 microns with a 99 percent efficiency rate or less.

They are different infiltration efficiency that captures different microns sizes. They are both filters more often for industrial air purifiers.
