Fleet managers and regulators are always trying to improve safety. Breathing cleaner cabin air may help drivers be more alert so they can finish their routes safely. A clean, healthy cabin can also be a great way to recruit qualified drivers, who are becoming increasingly harder to attract and retain. Luber-finer cabin air filters help improve the quality of a driver's home-away-from-home. A Luber-finer cabin air filters help trap bacteria, dust, pollen, and exhaust gases that come through your truck's ventilation system. Cabin filters are particularly beneficial for people with allergies. Luber-finer recommends that cabin air filters be changed every 18,000 miles or once a year.
