I need a filter for my unit, but I’m not sure which model I have. How do I find out which unit I have?
You can find the model designation on a label inside the unit. Open the front cover and look for an identification label, usually located on the inside, often on one of the side panels. The label shows the model name and serial number, for example Flexit UNI 4 or EcoNordic WH4. Once you have the model name, you can easily find the correct filter at flexit.no/filter.
