How to Properly Use Cabin Air Filters in a Vehicle

You may think you know everything there is about your vehicle, but unless you’re checking the cabin air filters on a regular basis, it might surprise you just how much dust and other debris that the filter is keeping out of your car. Take a look at this infographic and find out more!

Dusty air can cause allergies and make passengers sick.

About 70% of the particles in your car are from outside, entering through the vents.

The combination of moving air and an exterior-facing opening makes it difficult to keep dust at bay.  

Are you interested in how cabin air filters work? Have a look here:

The cabin air filter is part of your car’s heating, ventilation and air conditioning (HVAC) system, removing contaminants that come into the vehicle through the heater or AC system before they reach your lungs. Substances like pollen, bacteria, fine dusts and chemicals — even exhaust gases — get stuck on the fibers inside cabin air filters while others are trapped in the filter’s outer pleats.

Some Frequently Asked Questions about Cabin Air Filters:   

1) Is my car equipped with cabin air filters?

If you want to know if your car is equipped with a cabin air filter, start by looking at your owner’s manual. If there’s no mention of it in the manual, look under the hood and underneath the dashboard on either side of the glove compartment. You should see two rectangular boxes that look like any other part in your engine bay – most cabin air filters are located just behind the back side of the glove box up near where the blower motor would be.

2) How often do I need to replace my cabin air filter?  

Cabin air filters are inexpensive and easy to replace. Changing them regularly is just good practice, especially if you live in a dusty environment or do lots of driving on dirt roads. You also have to keep an eye on the condition of your cabin air filter since it will get clogged with debris over time and won’t be able to do its job. As soon as your vehicle’s HVAC system starts blowing out dusty air, that’s the warning sign that you need a new one!

3) How can I tell if my cabin air filter needs changing?

The most obvious indication your car requires a new cabin air filter is when the HVAC system starts blowing really dusty air through the vents even though you haven’t changed anything else. But, there’s also a telltale sign that your cabin air filter is dirty: dust and other particles start sticking to the outside of the box after it’s been in service for 100,000 miles or so – whichever comes first!

4) Will buying a cabin air filter help me save money on my car insurance?

It does not matter where you buy your cabin air filters. Because those parts are pretty much standardized across makes and models; however, drivers should always consult their owner’s manual to make sure they buy the right part before tossing anything away. Doing this can save them time and money as well as prevent them from putting. The wrong filter into place (or getting dinged at their next dealer visit).

5) Will cabin air filters help me pass DEQ inspections?

Cabin air filters are designed to increase your car’s mileage by improving the quality of the air inside. They’re also supposed to improve engine performance, but there’s no evidence. That they’ll keep you from getting failed on a DEQ inspection. If you do get dinged on an emission test. Consider taking your car to a local garage or dealership for repairs; it could be as simple as replacing one or more parts – like oxygen monitors and catalytic converters. And even cabin air filters! – Before you pay another DEQ inspection fee.  

6) What kind of cabin air filter is used in my vehicle?

A lot of automakers use pleated paper cabin air filters in their vehicles. These are thinner than the cotton and foam ones some automakers use instead. So they’re easier to replace and offer better performance without breaking your bank account.

7) Are there any foolproof ways of telling which kind of vehicle I’m driving?

Not really; automakers like to protect their trade secrets and specs on cabin air filters can vary. Within a model range (and even between trim levels). Your best bet is to pay attention to what you see under the hood or inside of your glove compartment. If it looks familiar, chances are you’re good to go; if not, call a professional!
