You’ve heard of a car cabin air filter. It’s mentioned every time you stop by your local mechanic for an oil change. But what is it, and why is it so important? You might also be wondering how often you should change it, and how to choose the best cabin air filter for your car. Fortunately, we’ve got you covered. Keep reading to learn more about cabin air filters and see our top picks for 2020.
How to Choose the Best Car Cabin Air Filter
Before jumping into our picks for cabin air filters, let’s talk about the different types to choose from and what key factors to consider when buying a new cabin air filter.
Types of Cabin Air Filters
You know that it’s the time to invest in a new cabin air filter for your trusty four-door, but how do you know which type of filter is best? While each type of cabin air filter is designed to handle dust and odors, not all do so in the same way.
Charcoal Cabin Air Filters
Charcoal cabin air filters catch dust and debris while also absorbing nasty fumes and unpleasant odors. For the best results, charcoal cabin air filters should be changed once per year or every 15,000 miles.
Activated Carbon Cabin Air Filters
Activated carbon filters work the same way as charcoal cabin air filters but use activated carbon to absorb airborne contaminants that pass through your vehicle’s ventilation system.
Particle Cabin Air Filters
Particle cabin filters trap tiny particles before they enter your car. These filters are ideal for filtering out pollen, dust, smoke, mold spores, and other small particles.
Electrostatic Cabin Air Filters
Each layer of an electrostatic cabin air filter is electrostatically charged so that the filter can trap ultra-fine particles, including cigarette smoke, exhaust fumes, mold spores, bacteria, and diesel carbon.
HEPA Cabin Air Filters
HEPA stands for High-Efficiency Particulate Air. These filters provide a filtration efficiency rate of 99.7% at 0.3 microns, blocking out allergens like pollen and dust. However, they’re not as good when it comes to filtering out harmful odors.
Key Features to Look For in a Car Cabin Air Filter
Much like anything, there are a few key features to look out for when buying a car cabin air filter:
Compatability
Each model of car requires a specifically-sized air filter. While a brand may claim to have a universal fit, that’s not necessarily true. Before you commit to buying a cabin air filter, check if it’s compatible with your car.
Protection
Cabin air filters are designed to block out dust and dirt particles. Some are also able to take on foul odors. If you’d like a cabin air filter that can protect against even finer particulates and more pungent odors, be sure to buy a filter like the K&N Premium Cabin Air Filter.
Longevity
While some cabin air filters need to be changed after one year or 12,000 miles, others can last for even longer.
Driving Conditions
Do you live in an urban environment plagued by pollution? Then consider a HEPA-rated filter like the Bosch 6055C HEPA Cabin Air Filter. If you don’t, an air filter like the Spearhead Premium Breathe Easy Cabin Filter may fit the bill better.
We have sorted through the bestsellers and forever favorites to find the best car cabin air filters of 2020. Check out our top picks below!
