Fasteners

These accessories help you attach the filter fabric to your window quickly and securely.
For ventilation hatches, the Sarne filter is best attached with double-sided tape or small magnets – if the outer grille is metal.

For glass windows, you can use double-sided tape on the outer molding or build a custom frame.
In wooden windows, you can secure the filter with staples or push pins.
For aluminum windows, the filter can be wedged between the outer trim and the frame using flexible foam or similar material.

We recommend protecting the filter with an insect screen.
