HEPA Filters

HEPA filters (an acronym for High Efficiency Particulate Air) are a type of filter used in air purification systems and hoovers to remove small particles and pollutants from the air.

More information

HEPA filters

HEPA filters are noted for their ability to retain extremely small particles such as dust, pollen, dust mites, mould spores, and even bacteria and viruses. They are extremely efficient and must adhere to strict standards to be classified as true HEPA filters. To receive this designation, a HEPA filter must be able to intercept at least 99.97% of particles measuring 0.3 micrometres or larger. Because of their efficiency, they are used in air purification systems in residences, health care facilities, laboratories and industrial sectors that require clean air.

There are various models of HEPA filters, such as fibreglass, pleated paper and microfibre. Regardless of type, they all aim to meet the criteria of filtration efficiency and capture of minute particles. They are particularly beneficial for individuals with allergies, asthma or conditions that are aggravated by the presence of pollutants and allergens in the environment.

Sectors and application

HEPA filters are versatile and are used in a variety of industries due to their ability to trap ultrafine particles. Some of the most prominent industries using HEPA filters include:

  • Hospitals or health centres: They are used in hospitals, especially in operating theatres, intensive care units and immunocompromised patient areas, to prevent the spread of micro-organisms.
  • Pharmaceutical industry: They are essential in production and research areas to ensure a sterile and contaminant-free environment.
  • Automotive: They are used in painting and finishing processes to ensure that the air is free of particles that could affect the quality of the finish.
  • Homes and offices: They are found in air purifiers and some hoovers to improve indoor air quality by removing allergens, dust and other pollutants.
