Grille Filters

Grille Filters provide a high-efficiency extended-life alternative to a 1" filter. These have a unique design that allow them to fit in the same space as a standard 1" return grille filter. These deep-pleated filters offer a much greater surface area for dust collection and allow a high level of airflow in comparison to a 1" filter.

* This type of filter is only designed for use in return grilles of wall and ceiling vents with at least 7" of open space behind the grille opening to allow for proper airflow through the filter.
