As the filter gets dirtier, the air flowing through your vent system could become restricted. This air restriction limits the efficiency of your air conditioning or defrost system. Extremely dirty filters can also be a source of unpleasant odor in your car.
Some of our filters contain carbon in the media. This is the same type of carbon known as "activated charcoal" used in water filters. The carbon gives the media its darker look. Where the original equipment filter is carbon, the Filterheads.com cabin filter is made with carbon media. Carbon is included in some cabin filters is to absorb odors from the air flowing through your vehicle's vent system.
It is a filter that cleans the air entering into the passenger compartment through the vehicle's vent system. It is similar to an air conditioning filter you may have in your house. It also helps keep the vehicles vent system and interior clean. Most cars manufactured in the past few years have one.
The filters we sell are "aftermarket" - which means they are made by a company that has no connection with the car manufacturer. The "Aftermarket" has both good and bad reputations. Some aftermarket brands are known for being better than the original parts. Other brands, unfortunately, give the aftermarket a reputation of being the cheap alternative to original parts. The parts we sell are as good as (and in some cases better than) the original parts. Each part is designed to meet or exceed the function of the original.
Most of our filters come from the factory in 3-pack cartons. If you are interested in ordering in carton multiples, we can give you a substantial discount. Contact us for a quote.
In general a cabin filter should be changed every 15,000 miles or once every year. The service interval can vary depending on your driving habits. In some instances the maintenance section of your owner's manual may list the recommended service interval for your vehicle.
The media in these types of filters will perform exactly the same in both directions when first installed. The difference between the sides is their capacity to hold particles before the filter becomes "clogged". The way filter media is tested is by measuring how much it restricts the airflow after a specific quantity of dust (grams) has been caught. A filter that is "backwards" will reach its maximum allowable restrictiveness at a lower number of grams caught. Most filter media (including ours) is made in layers. The more open weave layers are on the "input" side, and the tighter woven layers are on the "output" side. You won't damage your car by putting it in the wrong way. The filter will simply reach its maximum allowable restrictiveness sooner. A filter at or beyond its maximum allowable restictiveness will cause the vehicle's air system to move less air than intended. The most significant consequence would be ineffective defrosting of the windshield. The directional indication on the edge of a cabin filter will be oriented so that the higher capacity side will face the dirty incoming air.
We provide you with an instruction sheet and/or a video that shows you how to change your cabin filter and where it is located in your vehicle. Your owner's manual may also contain some of this information. Generally, the filter will be located behind the glovebox, below the glovebox, under the windshield cowling or under the hood.
