Better air quality doesn't just affect comfort — it affects sleep quality, focus on the road, and long-term health.

The Science

A piece of gear to trap, not just Mask odors

Most air fresheners mask odors with chemicals. CabGuard Air uses floating activated charcoal and they are permanently trapped.

A professional‑grade air tool engineered for long‑haul drivers who live, sleep, and grind inside their cab. Not a gadget. Not just a purifier. A piece of gear.

What It Removes
Diesel exhaust fumes
Nitrogen dioxide (NO₂)
Carbon monoxide (CO)
Volatile organic compounds (VOCs)
Truck stop odors
Body odor, sweat and animal dander
Food smells
Mold & mildew spores
Cigarette smoke residue
Chemical off-gassing
Features

Engineered for
the Long Haul.

Every design decision was made with one driver in mind — the one sleeping in their cab tonight.

Activated Charcoal Core

Medical-grade activated charcoal with a surface area of over 1,000 m²/g. Adsorbs diesel exhaust, VOCs, ammonia, and odor molecules at the molecular level — not just masking them.

Zero Electricity

No wiring. No batteries. No inverter draw. The CabGuard Air unit uses your existing cab fan as its engine — the fan you're already running to stay comfortable.

Rechargeable/Portable

The filter body is unscrewed and the activated charcoal is replaced, then connected again. Can be easily transportable.

Installs in 60 Seconds

The patented bracket system snaps onto standard 6" and 8" cab fans with no tools. No drilling, no modifications, no permanent changes to your truck.

In the Cab

Your Cab.
Your Air.
Your Rest.

OTR drivers spend more time in their cab than most people spend in their homes. The air quality in a sleeper cab — surrounded by idling diesels, truck stop fumes, and recycled air — is a real health concern.

CabGuard Air was designed specifically for this environment. It works with the fan you already run. It doesn't add noise. It doesn't draw power. It just cleans the air while you sleep.

Works while you sleep — no manual operation
Silent — no motor, no hum, no glow
Doesn't affect your fan's airflow or performance
Rechargeable activated charcoal. No constant replacements — built for long-term performance
