Window ventilation Grill filters

Healthy ventilation, you do that with HQ ventifilters in your supply grids.
The HQ fan filter filters dust and pollen from the incoming air coming from the outside. In this way your living spaces are supplied with fresh air and also serve as an insect repellent.
HQ ventifilters have an open structure and therefore allow easy air through. The ventilation grids thus maintain their ventilation capacity to a very large extent, so that you always get enough purified fresh air in your home.
HQ ventifilters are made of foamed polyester. This filter foam has a homogeneous, open cell structure and is limited cleanable and can therefore be replaced several times.
HQ ventifilters are aging-stable and can therefore be washed by hand in lukewarm water.
To prevent bacteria and fungus, the filters must be completely dry after washing before they are placed back in the grid.
Depending on where you live and the degree of air pollution is decisive when you need to clean / replace the filter. See the replacement frequency of the filter below.
In villages, agricultural areas, nature reserves, the recommended time for cleaning / replacing the filter is 3 - 4 months.
In large and small towns, the recommended time for cleaning / replacing the filter is 2 - 3 months.
For industrial zones, highways and busy roads, the recommended time for cleaning / replacing the filter is 1 - 2 months.
The HQ vent filters are placed behind the detachable hood of natural ventilation grids.

It is important to order the right filter, because 10 sizes are available.
Measure the height of the inside of the air clip. Based on this height you can order the filters: 30, 34, 40, 45, 47, 65, 70, 80, 90, or 120 mm high. However, you can always cut off a piece of the filter if it does not fit completely.
