Roof Air Intake Filtration System

A ceiling-integrated air purifier that draws fresh outdoor air through a weatherproof roof vent, filters it through a 3-stage stack, and delivers clean air directly into your living space.

What makes it different

Outdoor air source

Unlike recirculating purifiers, this system draws fresh air from above the roofline — so you're always getting new air, not recycled indoor air.

Architectural integration

Mounted in the attic cavity and delivered through a ceiling diffuser. No floor units, no visible equipment — just clean air from above.

Locally tuned filtration

Filter media selection is informed by local air pollution data — targeting the specific pollutants present in your area, not a generic national average.
