I need a filter but don’t know which model I have. How do I find out?

To order the correct ventilation filter, you need to know which ventilation unit model you have. The model name can be found on the unit itself.

Here’s how to find your model:

1. Open the front cover of the ventilation unit.

2. Locate the label inside the unit, usually placed on one of the side walls.

3. Note the model name and serial number, for example Flexit UNI 4 or EcoNordic WH4.

4. Search for your model name to find the correct filter.
