Introduction to HEPA filters

A HEPA filter is a specific kind of high-quality air filter that happens to meet the HEPA filter standard, which is responsible for removing at least 99.97% of particles from the air down to at least 0.3 microns in size. The HEPA filters are a very common component that is found in the air purifiers which filter the air in order to clean it- there are other types of air purifiers too such as carbon filter, ionizers and even non-filter purifiers. 

The HEPA filters are even used in vacuum cleaners and in various industries which require high air quality, such as aerospace, pharmaceuticals, nuclear power, and the manufacturing of computer chips. You can even buy the HEPA filter online for your use. 

HEPA, standing for High-Efficiency Particulate Air, is made up of thousands of extremely fine fibres that have been arranged into a matt to intercept both microscopic particles and larger ones. An air purifier helps to push air from the room through the filter in order to remove pollutant particles. Just by definition, the HEPA filters are able to trap close to 100% of the particles in the air that are 0.3 microns or smaller. 

Benefits of a HEPA filter

Once you have invested in high-efficiency particulate arrestance HEPA filters, you have bought technology that has been tested and approved against a standard. This helps to ensure the quality and reliability of the filter in order to remove even the tiniest airborne particles. Air filtration actually is much more important than many of us realize as indoor air contains many different irritants and pollutants. A HEPA filter that is correctly chosen is able to ensure that these pollutants are removed efficiently, greatly improving the quality of air you breathe. 

Why it is important to remove the small particles from the air

The various microscopic airborne particles are nearly impossible to see, but can even be taken into the lungs and be irritating or damaging to your health, especially for anyone who happens to suffer from allergies or asthma. The larger particles such as pollen, mould spores, dust and other such allergens are generally filtered out of our systems in the nose or throat. All of these large particles can easily be removed from the air by a HEPA filter.
