The new energy classification

Energy label 2015During 2012, the new energy rating system for air filters was introduced. From 2015 it starts at ”A+”, the highest (best) energy rating, and continues down to ”E”, the lowest.

The new classification simulates, by way of a standardized test dust (ASHRAE), the air filter’s energy consumption with high dust contamination during 6,000 hours of operation. By reading the start pressure drop and successively rising pressure drop when the filter is filled with test dust, theoretical energy consumption data can be calculated which is then used as a basis for classification.

The classification shows the importance of a large filter surface to attain the highest energy rating A. For highly contaminated* outdoor air (ODA3) or contaminations similar to the ASHRAE dust we recommend MaxFlo or Dinpleat with glass fibre media. Renewable materials (GreenFlo) are a better alternative for lighter contaminated environments, (ODA1-2) as hygienic aspects and real operational times must be taken into consideration.

* Dust contamination corresponds to ODA3.

Better environment, better air

During the last 20 years, outdoor air in Europe has become increasingly clean. The CO2 level in the atmosphere is the new major threat to our security and well-being. Both conventional filter materials – synthetic and glass fibre (MaxFlo) – but above all, renewable materials such as PLA (GreenFlo) are required to save energy, money and CO2 in real operational environments.

A basic theory we at Dinair advocate is that all filtration should be cost-effective and sustainable in the wider perspective. We want to make use of renewable materials to the maximum possible extent as the air filter’s lifecycle ends with incineration. Thus materials, such as fossil plastic, are relegated/deemed to be unsuitable for air filters – even if they have been recovered from recycled products.

City or countryside?


Different environments require different types of filtration. Smaller towns often have types of air differing to those of city centres.
