01

The idea behind the hardware

Inventor & owner

A return grille that is easier to live with.

Impeccable Air founder and mechanical engineer Dominic Pecchia is the named inventor on four issued U.S. patents. Public patent records list Filtrex Pure Air LLC as the applicant or assignee of these vent-assembly inventions.

The patents describe mechanical approaches to attaching a grille at an air-duct opening and making the grille and filter easier to access. Their shared theme is practical: a vent assembly designed around installation, maintenance, and everyday use.

The inventions concern the construction and methods of vent assemblies. They are distinct from laboratory claims about how much airborne contamination a filter removes in a home.

03

The engineering in practice

Design principles

A vent you can install, inspect, and maintain.

01 / INSTALL

Think beyond screws.

The patent documents describe clip-based attachment arrangements that can allow a vent housing to engage a compatible wall or duct opening without conventional screw or bolt fastening.

02 / ACCESS

Keep the filter within reach.

Several disclosures place a removable filter behind an attachable or hinged grille. The aim is to allow filter access without treating the entire installed assembly as a disposable component.

03 / SERVICE

Design for cleaning, too.

Related patents discuss grille opening or removal to help with cleaning and maintenance. The exact construction and fit depend on the specific vent design and installation conditions.

What does a patent number mean for a product?

An issued patent protects the subject matter defined by its granted claims, not every feature discussed in its description. Different patents may cover different components or methods, and not every listed patent necessarily applies to every Impeccable Air product or version.

This page is a portfolio overview, not a product-specific patent-marking statement or a legal opinion on claim coverage. The original patent documents are the authoritative source for the issued claims. For current product fit and maintenance instructions, see our fit guide and installation guide.
