We spend a lot of time thinking about how our cars look, how they drive, and how often we fill the tank. But what about the air we breathe inside them?
Most drivers don’t realize it, but the air inside your car can actually be more polluted than the air outside—sometimes up to six times worse. Exhaust fumes, dust, pollen, bacteria, and even unpleasant smells all find their way into the ventilation system. And the only thing standing between you and all that? Your cabin air filter.
So, What Does a Cabin Filter Actually Do?
It’s a small component, but it does a big job. Your cabin filter is what keeps the air clean as it flows through your car’s A/C and heating system. It catches all kinds of things:
- Dust
- Pollen
- Mold spores
- Airborne bacteria
- Pollution from traffic
Over time, like any filter, it gets full. And when it does, it stops working properly—making your car smell musty, reducing airflow, and letting dirty air circulate inside.
When Should You Change It?
The general rule is once a year or every 12,000–15,000 km, but it depends on how and where you drive. If you’re often stuck in city traffic, driving on dusty roads, or have allergies, it’s worth changing it more frequently.
Some signs it might be time:
- A stale or musty smell in the car
- Your air conditioning isn’t working as well
- You find yourself sneezing or feeling stuffy while driving
Aircab: A Cabin Filter You Can Count On
If you’re going to change it, make it count. We’ve been testing different filters in the market, and Aircab stands out for a few key reasons.
First, they’re built with high-efficiency filter media, meaning they actually do what they claim—trap fine particles, neutralize odours, and keep the airflow strong. They also fit properly (which, believe us, is not a given) and are made to last.
We’ve come to trust Aircab as a brand that balances quality and reliability, especially when it comes to something as important—but easy to forget—as the air you breathe.

A Small Change with a Big Impact
Cabin filters might not be the most glamorous part of your car, but they’re one of the few that directly affect your health and comfort. Clean air makes a difference—especially for those with allergies, sensitive skin, or kids in the back seat.
So next time you’re in for a service, ask:
“When was the last time my cabin filter was changed?”
And if you’re due, go for something you can trust—like Aircab.
Because taking care of your car should always include taking care of yourself.
