Additional set of coarse filter mats
Placing prefilter coarse mat G4 before the fine filter cassette F7 on supply air side, enables the filter cassette to last clean longer.  However, the filter mats get dirtier faster and need to be replaced more frequently, than the fine filter cassettes. By only changing the coarse filters (for supply - and extract air) more often, you don’t need to change the more valuable filter cassette (F7) each time. Having additional coarse filters ready at home saves you some money and enables you to change the coarse filters fast when needed.

Cleanser for the heat recovery cell
In order to keep the ventilation unit functioning properly, the heat recovery cell needs to be cleansed regularly. Use only suitable cleaning products, when cleaning it. We recommend Likavex- cleanser, which is safe to use for cleansing ofventilation units but also for example chrome-plated surfaces, aluminum, tile, vinyl, fiberglass and marble, wheels and tires and also car seats.

FILTERCASSETTE

• The cassette filter is made from a polyester that is resistant to the humidity in the air
• The cassette has a sturdy frame, which doesn't reduce the filtration area
• In connection to the filter change, it's good to clean the ventilation unit and remove possible loose dirt for example with a vacuum cleaner

The recommended interval for filter changes is 2–3 times a year. The coarse filters can be replaced more often if needed. You can easily add extra G3 coarse filters to your order.
