When you shop for a filter or a vacuum cleaner, you might have noticed the acronym HEPA. The term appears on many products that have filters in them too.
What are HEPA filters
HEPA stands for ‘High Efficiency Particulate Air’. It is an efficiency standard measure for air filters. You might have noticed that manufacturers of filters brag of their products meeting True HEPA standards. A filter that can arrest 99.97% of airborne particles such as mold spores, allergens and dust is referred to as a HEPA filter. These particles should be 0.3 microns. HEPA filters are used in a myriad of applications. They are found in hospital equipment, vehicles, home and office air purifiers, disk drives, and so many other areas. HEPA filters are made of interlaced glass fibres that are intertwined to create a fibrous maze. When particles transverse this network, they are trapped and hence taken out of circulation.
