Fresh Cabin Air Filters Help Purify The Air That You And Your Family Breathe While You Drive

Release Date: 5/10/2010 

BROADVIEW, IL, May 10, 2010 – Did you know that dust and allergens can sneak into a vehicle’s interior as you drive, even when the windows are rolled up? And, did you know that many cars today are factory-equipped with cabin air filters that prevent this dirty air from entering the vehicle in the first place? Furthermore, did you know that these filters – to be effective – must be changed periodically?


Although cabin air filters have been showing up in newer model cars for more than a decade, few motorists seem to be aware of their existence, or the benefits they offer in helping us breathe clean, healthy air while we drive.


“A fresh cabin air filter cleans the air that the driver and passengers breathe, reduces the accumulation of dust inside the car, and helps keep the interior air clean and fresh,” says Ramon Nuñez, spokesperson for Purolator Filters NA LLC. Purolator manufactures and supplies BreatheEasy® cabin air filters for most domestic and imported vehicles in the North American automotive aftermarket.


Purolator’s BreatheEasy cabin air filters feature specially engineered, non-woven media that can capture and hold even the finest particles of contaminants such as dust, soot, pollen, fungus and bacteria.


Two kinds of cabin filters are available for modern vehicles – the particulate cabin filter and the activated charcoal cabin filter. The particulate cabin filter features more surface area to filter out pollutants and irritants .The filters are also electrostatically charged, similar to many household HVAC filters, ensuring that particles stay attached to the filter.


The activated charcoal cabin filter adsorbs most toxic and foul-smelling gases such as ozone, nitrogen oxide, sulfur dioxide and hydrocarbons, keeping odors out of the cabin.


Purolator offers both particulate and activated charcoal cabin air filters for many vehicles. Either type may be available depending on the make/model of a vehicle.


Cabin air filters are usually inexpensive and fairly easy to replace. For best results, Purolator’s Nuñez suggests they be replaced every 12 months or 12,000-18,000 miles. They can be installed in anywhere from less than 10 minutes to about an hour, depending on the location. The cabin air filter is usually found under the dash, behind the glove box, or in the air box in the engine compartment. Purolator BreatheEasy cabin air filters come with an illustrated, vehicle-specific instruction sheet to assist with installation.


Motorists who have any filter-related question, may access the Purolator Response Office or PROs free of charge at From application data to installation procedures, the Purolator PROs can answer virtually any question about filtration. Purolator PROS will send a personal reply via e-mail or phone within 48 hours.


Recent estimates show that since 2001, approximately 45 million vehicles in the U.S. have been factory-equipped with cabin air filters.
