Window Filter

If you're sensitive to pollens and molds and want to enjoy an open window, our Window Filters are just for you. Pollen, dust and mold are kept outdoors by this unique Window Filter. Its patented triple-filtering air baffles allow only clean, fresh air to enter. It can be used in any season since it is not affected by rain, snow or high winds. Its sturdy aluminum frame makes it easy to install in any double-hung casement window. To clean, just rinse it off under running tap water. The small Window Filter is 7" high and adjusts to fit any window 20" to 36" wide. The large Window Filter is 11" high and fits any window 24" to 44" wide.
