NEW! Sarne Flow – Thin but powerful allergy filter

Sarne Flow is an excellent summer filter – it allows air to flow through easily while still maintaining high filtration performance. Its effectiveness is based on electrostatic charge, which captures even fine airborne particles efficiently, despite the fabric being very thin.

Flow is especially well-suited for summer use, as homes heat up and good airflow is essential – particularly in houses with natural (passive) ventilation, where airflow tends to decrease during warm weather.

Pollen, mold spores, and street dust are effectively captured by the filter. Thanks to its low air resistance, Sarne Flow can also be used as an additional filter in mechanical ventilation systems to block dust, microbes, and particles from sound insulation materials from entering indoor spaces.

The filter can be attached to a window using double-sided tape. For wooden windows, you can reinforce the attachment with tacks or a stapler. For aluminum windows, wedge foam or other flexible material between the window trim and the frame. In large or windy windows, it’s especially important to secure the filter well.

When used in a ventilation hatch with a metal (non-aluminum) outer grille, the easiest attachment method is with magnets.

Sarne Flow contains less particle-binding material than Sarne Pro, which means its lifespan is slightly shorter – but it remains effective for at least one summer.

The fabric is easy to cut with scissors.
