How do you fit a window filter?

Doors and balcony doors

For places you pass through often, such as a balcony door, fitting the filter to a hinged screen door is the most practical method. If you have a hinged screen door, you can replace its mesh with a filter roll. If not, your screen maker can make a hinged frame with the filter. Hook-and-loop fitting is also possible on doors, but because you would need to remove the filter every time you go through, it is best where the door is rarely used.

Vents and air inlets

For small air inlets and kitchen and bathroom vents, just cut the filter slightly larger than the opening and stick hook-and-loop tape around it. The filter gets dusty faster in these places; we recommend checking it once a month.
