Ready for ISO 16890

Industrial filter solutions customized to your specific application requirements

The new standard for classifying air filters came into force and is completely changing the way filter efficiencies are determined and categorized.

 What is the difference between the two standards?

So far, it was difficult for the customers to select a filter that fits their application and the actual pollutants, based on EN779:2012 standard. The new ISO standard will solve this issue, linking the filter element performances to outdoor air pollution, making it easier to find the products that are matching your needs. Moreover, acc. to ISO16890, measurement of filter element separation efficiency is performed by using global standardized particle distribution from urban and rural environments, instead of using synthetic test dust in laboratory acc. to EN779:2012. The EN779 classifies filters based on on a single particle size - 0.4 microns and none of the other particle sizes in the air. With the new rating system, a filter efficiency is now determined and classified based on tests with different particulate matter range (0.3 to 10 microns). 

Why is important to choose your filters according to ISO16890?

Today, air pollution is a big concern as 91% of the world’s population lives in places where air quality levels exceed the World Health Organisation's limits. The human system cand only stop the particles bigger than 10 microns and depending on their size, the smaller particles travel through human bodies causing cardiovascular and respiratory diseases and more than three million premature deaths annually.

Classifications 

According to ISO16890, a filter element will be classified within these four groups: Coarse, ePM10, ePM2.5 and ePM1. For each category, a filter must be able for capturing at least 50% of the particles of a specific size range. If this is met, the average efficiency value will be rounded in 5% increments.

The new ISO16890 will be the leading standard for general air filter evaluation and will be globally applicable in coming years, which makes a harmonization in the air filtration industry. Overall, the industry feedback in relation to the standard has been positive as it enables a more precise selection process for air filters going forward.

Under ISO16890, the way of choosing and cutomise your filter will be much different. It demands more accurate information about the application from the end-users side, but it will help them to choose the proper filter according to their individual application.
