Benefits & Features of Cabin Air Filters

If you are concerned about the quality of the air entering your vehicle’s interior, a new cabin air filter is a simple way to improve the air quality and airflow from your heating and A/C system. The layered filter traps and collects dust, gases, pollutants, pollen, and soot to ensure they do not reach your cabin. Replacing the cabin air filter to keep the inside of your vehicle free from contaminants is another way to protect yourself from pollution, dust, bacteria, and ensure that the air you’re breathing in your car is as clean as possible. Quickly and easily improve the air quality inside your car, truck, van, or SUV with a replacement cabin air filter.

When Should I Change My Cabin Air Filter?

Cabin air filters help trap and remove contaminants from the outside air before entering your vehicle’s cabin, to provide your heating and A/C system with clean air. Cabin air filters can reduce allergens, dirt, and dust inside your vehicle’s cabin, and replacing the filter can improve air quality, airflow, and A/C system performance. It’s recommended that you replace the cabin air filter every 15,000 to 20,000 miles, but if you notice decreased A/C performance, you can change the filter more often. A clogged cabin air filter can create odors or a lack of airflow in the cabin, and should be checked and replaced if you notice these symptoms.

A High Efficiency Particulate Air (HEPA) cabin filter is designed to trap microscopic contaminants, which may include fine dust, gases, and pollutants, and prevent these from entering your vehicle’s air conditioning or heating system. A HEPA cabin filter can help improve your passenger cabin’s air quality and keep you more comfortable while driving. The MicroGard HEPA cabin filter has a filtration efficiency of 99.97%, which can remove even extremely fine particles from the air from the vents. HEPA filters are designed to trap microscopic particles, great for drivers or passengers that are sensitive to odors, have airborne allergies, or those that live in regions with high pollution or wildfire rates. The five layers of the HEPA cabin filter make up a dense media that enhances its ability to trap contaminants, and are an improvement over the industry standard two-layers cabin air filters often installed from the factory. Not only will your vehicle’s air be noticeably cleaner, but there will be less dirt particles built up on fans and A/C equipment, keeping your climate control system working at its best.
