When was the last time your cabin air filter was replaced? Twenty First Century Auto in Milwaukee has the experience, and expertise to replace your cabin air filter in a timely fashion. The cabin air filter traps smog and other pollutants from getting inside of your vehicle. Because it filters air to the inside of the car (cabin), an old or contaminated air filter may damage the heating, ventilating, and air conditioning (HVAC) systems of your vehicle. The cabin air filter contributes to the quality of air you and other passengers breathe. A new cabin air filter adequately protects against pollen, dust, bacteria, and exhaust. Most automakers recommend replacing the cabin air filter on a regular basis. If you have questions about whether your cabin air filter should be replaced, or inspected, call Twenty First Century Auto in Milwaukee at 414-541-6229. You may also schedule an appointment online.
