AllerTech Vent Guard

Our allergen-trapping, multipurpose Vent Guard is extremely efficient in reducing exposure to dust blown into a room by a forced air system. By placing Vent Guard inside or outside the incoming air supply vent, you reduce your risk of an adverse reaction to these contaminants. Simply cut to size and attach inside or outside the vent using the optional magnetic installation strips. The strips can be used time after time and do not leave a mark. The five-foot roll of Vent Guard is enough for 20 vents and each installation kit handles four vents.

Window Guard

If you're sensitive to pollens and molds and want to enjoy an open window, our Window Guards are just for you. Pollen, dust and mold are kept outdoors by this unique Window Guard. 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 Guard is 7" high and adjusts to fit any window 20" to 36" wide. The large Window Guard is 11" high and fits any window 24" to 44" wide.
