Types of air filters and their application

There are various types of filters, each suited for specific applications:

  • Prefilters: Efficiencies G2, G3, and G4 (from Coarse 40% to Coarse 65%). They are used to capture large dust particles and protect the components of ventilation systems.
  • Fine filters: Efficiencies M5, M6, F7, F8, and F9 or ePM10 50% up to ePM1 80% according to ISO16890 standard. They are used to capture fine particles (invisible to the naked eye), thus contributing to improved indoor air quality.
  • Absolute filters (Efficiencies E10, E11, E12, H13, H14): They are used in critical applications where a high level of air purification is required, such as clean rooms and hospitals. These filters capture ultrafine particles.

Différents types de filtres à air de ventilation

The importance of air filters in building ventilation.

There are different types of filters, each tailored to specific applications: Air filters play a crucial role in building ventilation by providing healthy indoor air and protecting ventilation system components.

Indeed, air filters are used in Air Handling Units (AHUs) and rooftops to remove fine particles and other air contaminants, ensuring excellent indoor air quality.

Moreover, they contribute to human health protection by purifying the air we breathe and preventing allergies and respiratory diseases through effective ventilation and air renewal.

How to determine the performance of an air filter?

The performance of an air filter is determined by several factors, including its filtration efficiency and pressure drop. The pressure drop of an air filter represents its air resistance. The higher it is, the more energy the ventilation system will consume to circulate air within the building.

Therefore, it is crucial to choose an air filter with low pressure drop and laboratory-certified according to current standards to reduce energy consumption associated with ventilation.

Regular replacement of air filters is essential to maintain the performance of your HVAC system.
