The filter set contains 1 x ISO course 30% exhaust air filter and 1 x NOx filter.
The ISO coarse 30% exhaust air filter is a grit filter. The NOx filter filters harmful and irritating substances from the air. This helps to keep the indoor environment free from dangerous nitrogen oxides such as car exhaust fumes, as well as pollen and fine dust (F7).
Compatibility.
This filter set is compatible with the VT WRG & the VT WRG PLUS. You can check compatibility using the configuration key. If the filter identifier is a 1, the filter set is compatible.
Identification.
The filter identifier in the configuration key must be read to identify the correct filter set. To do this, open the inner panel and remove it. You can now read the filter identifier on the label by looking at the 3rd character of the configuration key.
