ORIGINAL ENERVENT LTR-4 - filter

• 1 pc supply air filter
• 1 pcl exhaust air filter
• Filter classes: selectable

Please choose filtration class according to your needs. There are three different sets available.

Usually the filtration level of an (F7/M5) or an (M5/M5) filter is enough for supply air and exhaust air. But if you want to improve the level of filtration among other things because of pollen allergies, you can for example choose a more effective F7 filter for the supply- and for the exhaust air.
