Frequently Asked Questions
Frequently asked questions ordered by popularity.
Filter class refers to the size and amount of particles a filter can trap. The higher the classification, the more effectively the filter removes particles from the air.
For incoming outdoor air, it’s generally recommended to use higher-class filters. However, we always suggest following the manufacturer’s guidance and using the specific filter sets outlined in your unit’s eco-commissioning documentation.
For more information, take a look at our comprehensive guide to filter classes for heat recovery units.
