Allergy filter for window

Filters for ventilation windows and air vents

CLEAN AIR INDOORS WITH SARNE FRESH AIR FILTERS!
Sarne Pro and Sarne Flow electrostatic filters are more than just pollen filters — they effectively block even the smallest and most harmful air pollutants from entering your indoor space.

Sarne fine particle filters are ideal for use in ventilation windows and fresh air vents. Even the tiniest particles are captured by the filter fabric thanks to the electrostatic charge in its fibers. This means the fabric doesn't need to be densely woven to be effective — fresh air can flow through it freely.

We offer Sarne filter fabric in two quality options. Sarne Pro is possibly the most efficient filter fabric on the market, combining excellent air permeability with top-tier filtration. It’s an outstanding allergy filter, stopping virtually all pollen and mold spores. In addition, it effectively filters even microscopic pollutants considered most harmful to health — such as those from traffic, wood burning, wildfires, and other long-range emissions.

Sarne Flow is a thinner fabric. While it’s slightly less efficient than Pro, it allows even better airflow, making it a great choice for summer use when natural ventilation tends to be weakest. Sarne Flow still filters well without restricting airflow too much.

Thanks to their efficiency and low air resistance, Sarne filter fabrics can also be used as supplementary filters in mechanical ventilation systems — helping to block dust, microbes, and fibers from sound insulation materials from entering your indoor air.

Sarne filter fabric is available cut to custom size or in pre-cut pieces from our online store. You can also contact us by email or phone to order custom lengths. For ventilation hatches, the Sarne filter is best attached with double-sided tape or small magnets, if the outer grille is metal. See: Tapes and magnets

For glass windows, you can create a custom-sized frame or simply attach the filter to the outer moldings with double-sided tape. In wooden windows, staples can be used for secure attachment, while in aluminum windows the filter can be wedged between the outer trim and frame using flexible foam or similar material. Using an insect screen on top is recommended.

We also sell activated carbon filters for odor removal, both in pre-cut sizes and custom-cut on request.
