Cab FreshFilter Co.

About Cab Fresh

Built in Greentop, Missouri — for drivers who live in the cab.

Cab Fresh Filter Company manufactures a patented filter device that mounts to the air intakes of the heater and air-conditioning systems on virtually every over-the-road truck — and most heavy-duty pickups. Every filter we ship is engineered, assembled, and tested in northeast Missouri.

The Cab Fresh story

Cab Fresh was founded to solve a simple problem: the air drivers breathe in their cabs is some of the dirtiest air in the country. Diesel exhaust, dust kicked up from gravel lots, pollen during spring runs, and the road grime kicked up by 18 tires — none of it stops at the windshield.

Our answer is a patented dual-layer cabin air filter that mounts at the air intake of your HVAC system. The primary particulate layer traps 97% of diesel soot, dust, and dirt; the activated charcoal layer cuts odors and road grime by 76%. Together they protect the driver, the interior, and the HVAC cores from clogging.

Every filter installs on most trucks with no drilling required. Push-pull fasteners and screws hold the filter firmly in place — and they're reusable, so the filter stays put through truck washes, pressure rinses, and long-haul abuse. Replacement elements are available at your dealer, and every Cab Fresh filter is 100% guaranteed.

Today, our parts reach drivers through more than 800 dealers across the USA, Canada, Mexico, and Australia. We supply Freightliner's Paragon Program, International's Navistar Program, Peterbilt, Kenworth, and Mack — and we make fitments for Ford, Chevrolet, and Dodge heavy-duty pickups too.

What sets us apart

The four pillars of every Cab Fresh filter

Patented dual-layer system

A particulate primary layer paired with activated charcoal — purpose-built to capture diesel soot, dust, dirt, pollen, and road odors before they reach the cab.

No-drilling install

Push-pull fasteners and screws hold the filter firmly in place. Reusable hardware means you can wash the truck without removing the filter.

Tougher on what truckers face

Diesel exhaust, gravel-road grime, hay-field pollen, freeway brake dust — we've engineered for them all, then validated with drivers who haul through them every day.

800+ dealers, four continents

We supply over 800 dealers across the USA, Canada, Mexico, and Australia, including Freightliner's Paragon Program, International's Navistar Program, Peterbilt, Kenworth, and Mack.
