Scope of the programme

The Eurovent Certified Performance (ECP) programme scope for Air Filters (FIL) covers air filter elements rated and sold as ISO ePM1, ISO ePM2.5 and ISO ePM10 according to EN ISO 16890-1:2016. Air filters must have a front frame size of 592x592mm according to standard EN 15805:2010, and with a nominal airflow between 0.24 and 1.5 m³/s. When a company joins the program, all relevant ISO ePM1, ISO ePM2.5 and ISO ePM10 air filter elements shall be certified.

As manufacturers may produce a large number of filters with different length/depth, there is a tolerance for the declaration of filters belonging to the same filter family. Already certified filters, with the same nominal airflow and with different length/depth of the overall filter element, within a tolerance of +/- 10% or 50 mm (whatever is the smaller) shall be included within the filter family. Air filters outside of this tolerance need to be declared.

The following filters are specifically excluded from the scope as set out in the Technical Certification Rules:

  • ISO Coarse filters
  • All combination filters with active carbon.

Certify-all principle

Whenever a company participates in the programme for air filters, all filters that are promoted by the applicant/participant to end-users, specifiers, trading companies, contractors by means of paper or electronic catalogue, price list or software within the scope of the programme, shall be certified, in accordance with the Technical Certification Rules. This includes all models in modular ranges. For the air filters programme, the certify-all requirement as defined in the Certification Manual is applicable to the European market and the Turkish market (since 1st January 2019).

Product type

Air filters are a HVAC system component, designed to remove harmful particles from the air. They can be used at different stages of air treatment and are utilised predominantly in air handling units (AHUs) and ventilation systems in buildings. Air filters operate in a wide range of commercial, industrial and residential applications. They are available in a number of designs and classes, using different filter media including glass and synthetic (or a mix of the two). Air filters impact on the energy efficiency of a system, accounting for around 15% of building energy costs. It is therefore important to ensure systems are using the correct filters to enhance indoor air quality and system efficiency.

Typically, an air filter will include a filter material and supporting parts and gaskets, that are inserted into a filter housing device. Air filters come in a range of designs including:

  • Bag
  • Filler mat
  • Panel
  • Pleated
  • V-type.

Filters also come in a range of classes which include three fine particle filter groups called particulate matter efficiency (ePMx), and one course particle group called ISO Coarse, for particles 10 micron or larger. Then ePMx is the efficiency of an air cleaning device to reduce the mass concentration of particles, with an optical diameter between 0,3 μm and x μm. ePMx is grouped into three groups, according to particle size filtered:

  • ISO ePM1 – for particles 0.3 micron to 1 micron in size
  • ISO ePM2.5 – for particles 0.3 micron to 2.5 micron in size
  • ISO ePM10 – for particles 0.3 micron to 10 micron in size.

Definitions

While exploring our certified products you’ll come across a number of technical terms relating to certification. The below definitions help explain the search criteria in our certified product directory.
