Why Do You Need a Car Interior Air Filter?

Is the car interior air filter really important? It’s just plain air after all. Could a filter really be that necessary?

Well, it is: the car cabin air filter guarantees that the air you breathe in your car is healthy, free of particles, germs, and pollutants. That’s why it’s important to replace your cabin air filter from time to time, ideally at least once or twice a year.

But, the car cabin air filter also affects your AC performance. Read below to find out why!

What does a car interior air filter do?

A car cabin air filter makes sure the air that flows inside your car is fresh and clean.

Well, at least that’s what it’s supposed to do: car filters get clogged up and if you don’t replace them regularly chances are you’re breathing in air that’s polluted and moldy.

A car cabin air filter works by trapping debris, particles, and bacteria in its layers, making sure that the air that goes into the cabin is healthy for your lungs.

PureFlow Air car interior filter has a 4-step filtering process:

Electrostatically charged, captures fine particulate capture (locks fine dust particles)
Activated charcoal traps mold and harmful gases

Does the cabin air filter affect AC?

Yes! The air for the AC of your car goes through the air filter.

And a clogged up cabin air filter means it won’t work well, which means you’ll need to crank up the AC to feel comfortable. This strains the HVAC system of your car, causing wear and tear due to the constant, intense airflow.

Also, a dirty air filter is one of the main causes of allergies and sneezing, so it’s a health hazard if you don’t replace it soon.

That’s why replacing your car cabin air filter once or twice a year is essential to maintain your car’s AC.


Does the cabin air filter affect gas mileage?

No, it does not. Cabin air filter cleans the air we breathe inside the car. It has nothing to do with the car or engine and it has everything to do with us - drivers and passengers. However, a clogged cabin air filter will obstruct the flow of air in your car’s AC and ventilation system. Often drivers mistake a poor flow in the ventilation system with a problem with the AC or the blower motor which can cost hundreds of dollars, while a simple replacement of the cabin filter will resolve the issue.
