A return grille, taken seriously.

The observation

Fig. 01

Dominic Pecchia is a mechanical engineer from Ohio and the named inventor on four issued U.S. patents.

The idea began with a simple question: could the return grille catch dust before it entered the ducts? Dominic saw an opportunity to add a filter right at the opening, in a place homeowners could easily reach.

The design

Fig. 02

A familiar part of the house, with a useful new job.

A replaceable carbon filter sits between the backplate and removable front. Square lower corners suit baseboard returns; clips secure the grille in compatible sidewall openings. The front comes off for filter checks, changes, and cleaning.
