company news about The importance of HEPA filters

The air we breathe daily contains many fine particles: dust, VOCs (volatile organic compounds), allergens, etc. This is particularly true indoors, where the air can be 4 to 5 times more polluted than outdoors, whether at home or in the workplace.

These particles can have consequences for health and be the cause of several cardiovascular diseases. To protect yourself, it is necessary to filter the air in your indoor spaces.

The most efficient type of filter

A HEPA (High Efficiency Particulate Air) filter guarantees a very high level of air filtration, capable of stopping airborne fine particles coming from outdoor air pollution, VOCs (volatile organic compounds), bacteria, or viruses.

In general, HEPA filters are the most effective means of filtering air from dirt, pollen, bacteria, and any particle with a size larger than 0.3 micrometers.

This type of filter can also be called a VHE (Very High Efficiency) filter.
HEPA FILTER: THE EN 1822 STANDARD
99.95% efficiency against fine particles
By its designation as HEPA, this type of filter refers to a certain efficiency standard: the EN 1822 standard. This standard includes filters that can eliminate 99.95% of fine particles with a size of more than 0.3 micrometers. In other words, to be called HEPA, a filter must eliminate 99.95% of particles of 0.3 micrometers.

For smaller particles, it is possible to go further by using ULPA (Ultra Low Penetration Air) filters, which are effective for particles of 0.1 to 0.2 micrometers.

Reasons to use a HEPA filter

A HEPA filter offers very high-quality filtration, which allows for excellent air quality and protection from certain pathologies.

This type of filter can thus be very useful for your home or workplace, but it is also used in many professional contexts, for which Deltrian can offer you a complete range of filters..

For example, this is the case in surgical operating rooms, which must be free of all bacteria and viruses. We can also mention pharmaceutical laboratories or cleanrooms where microprocessors are manufactured, which need to have optimal air quality to function normally.
