Cone filter

Cone filters are conical filters designed for use in ventilation ducts. The cone filters are made of a coarse filter media, stitched into a cone-shaped filter. A flexible ring is inserted into the opening. The filter is installed by compressing the ring, and the filter is inserted into the ventilation duct with the tip first. When the ring is released it expands again, and the filter wedges itself securely in the duct.

Therefore, it is crucial for a cone filter to precisely fit the duct.

The filter can be produced in various sizes, but standard dimensions are determined based on the standard measurements for ventilation ducts.
