Roof air intake filtration system
3-stage filtration. Engineered from the roof down.
A ceiling-integrated air purifier that draws outdoor air through a weatherproof roof vent, filters it through honeycomb carbon and HEPA media, and delivers clean air directly into your living space — no floor units, no portable filters. Patent Pending (USPTO).

Methodology
How it works
Outdoor air enters from above the roofline, passes through three filtration stages inside the attic cavity, and is delivered as clean air through a ceiling-mounted diffuser.
Roof vent intake
A weatherproof dome vent mounted above the roofline draws in outdoor air while keeping out rain, birds, and debris. The 45° rotated design maximizes airflow and minimizes weather intrusion.
3-stage filtration stack
Air passes through a honeycomb activated carbon filter (6" × 12", 1" thick) that absorbs odors, VOCs, and gases — then through a HEPA filter (6" × 12", 1.5" thick) that captures fine particles: dust, pollen, smoke, and more. Components are stacked flush with no gaps.
Ceiling delivery
Filtered air travels down an aluminum duct to a ceiling-mounted diffuser unit with a digital display. Clean, filtered air is distributed evenly into the living room below — integrated into the architecture, invisible in daily use.

Component specifications
Built-in filtration, not bolted on
Most air purifiers sit on the floor and recirculate the same indoor air. This system is different — it sources fresh outdoor air from above the roofline, filters it before it ever enters the living space, and delivers it through the ceiling. The result is genuine fresh-air ventilation with hospital-grade filtration.
Every component is sized and specified for the airflow path: the carbon filter handles chemical contaminants first, the HEPA layer captures particulates second, and the aluminum duct maintains pressure across the full stack.
