What Does a Cabin Air Filter Do?

A good cabin air filter screens out the heavy debris brought into your vehicle through your air intake, most commonly your car’s grill. The cabin filter also screens out much smaller particles and contaminants that would otherwise be blown into your vehicle’s passenger compartment through your heating or cooling system.

Signs of a Dirty Cabin Filter

Common signs of a dirty cabin air filter are poor air flow and unusual odors coming from the vehicle’s vents. If you are experiencing any of these signs and do not replace your filter, then you run the risk of incurring expensive HVAC repairs. And, when you pull it out, just a quick glance will tell you whether it’s still got plenty of white clean filters, or if it’s black and full of debris. The benefits of changing cabin air filters routinely far outweigh any inconvenience.

Car Cabin Air Filter Replacement

Most manufacturers recommend changing your cabin air filter once a year or every 15,000 miles. More frequent replacements may be needed if you live in an urban area. where you’re dealing with constant pollution, or in rural areas where your car is sucking up a lot of dust.

Breathe in better air, every day.

PureFlow Filters remove 99% of airborne contaminants.

Did you know that most cars have a cabin air filter to filter the air we breathe on the inside?

Just like the AC filter in your home, cabin filters should be changed throughout the year.

In just months, your car’s cabin filter can fill with dust, pollen, germs and exhaust from other vehicles restricting the airflow from inside your car, and filling the cabin with contaminants that can create an unhealthy environment for you and your passengers.

Trap Airborne Contaminants with PureFlow

What you need is a PureFlow cabin air filter – an easy-to-change filter that traps up to 99% of airborne contaminants BEFORE they enter your vehicle through the ventilation system, while also recirculating the air inside your cabin, improving the air quality for you and your family.

Benefits of Changing Your Cabin Filter

The cabin filter often gets overlooked when doing routine maintenance on your car. You change the oil, rotate the tires, but do you ever think about the cabin filter? Out of sight, out of mind. What does it even do? Why do you need a filter to block out the air from outside? Isn’t the outside air supposed to be good for you?

Well, there are a lot of things on the road that you don’t want to be breathing in, not the least of which are dust, leaves, pollen, mold, rodent droppings--and especially the exhaust from the car in front of you.

Why Do You Need a Cabin Filter?

As the name suggests, the best cabin air filter is designed to filter the air in your car so you can enjoy clean, breathable air. This may not sound like a big deal but imagine this: imagine your face at the height of your car’s grill, and keeping your mouth wide open while you drive. It sounds awful, right? Aside from the dirt, you’d get in your mouth from driving down a dusty road, just think of the pollution that is hanging out at street level on the highway.

Do you have allergies? They can be kicked up by pollen, dust, and mold spores--and all of those will get cleaned out by a good filter. Just like you have a filter at home in your furnace and air conditioner to keep the allergens at bay, you need the best cabin air filter to keep your car’s cabin pure and clean.

Worse still is the amount of exhaust that comes pouring out of the tailpipe of the car in front of you--that air is being sucked right into your car and going through your heater and air conditioner to be blasted in your face. You want it to be filtered, right?

And of course, a clogged air filter will slow down your car’s air system altogether so that it’ll be harder to cool and harder to heat.

What Are The Benefits of a Cabin Filter?

A cabin filter is meant to produce breathable air for you and your family to enjoy a more healthy and pleasant time while driving. The difference between a car with a cabin filter, and one without, is quite noticeable.

If you’ve never realized your car has a cabin filter, you may be surprised at the difference changing your filter can make. Have you noticed a musty smell when first entering your vehicle? This could be a sign that your cabin filter is dirty and needs to be replaced.

Your manufacturer has recommendations on how often to change your filter, but most mechanics agree about every 12,000 miles is sufficient, which is generally once a year. If you drive more, you may find you need to replace your filter more frequently.

Furthermore, you’ll know you need to change it more often if you frequently travel dirt roads, or live in places with heavy winds that produce dust storms. All of these things will clog your cabin filter faster. Also consider that heavy traffic increases pollution in the air, which tends to lead to the need for more frequent changes.

Perhaps the simplest way to know if it’s time to replace your filter is by looking at it. You can easily tell by the discoloration that your cabin filter is ready for replacement.

Improving the breathable air in your vehicle is not only better for your health, but it will produce a more enjoyable experience as you commute or travel.
