A/C Interior Cabin Air Microfilter - Change Recommended Every 2 Years

April 10, 2025

This filter or filter set, in some models, is working full-time, cleaning the air you breathe that is coming into the car through the air conditioning system. ( Unless your air conditioning is not working properly and you are driving around with open windows. That is another story. ) The micro filter is catching and blocking dust, pollen, allergens, soot, twigs & bird feathers, you name it! We see some pretty incredible things in these filters when we change them. A new filter has the ability to screen out particles down to 3 microns in size. That is the same as a N95 face mask. Think about that! Is your A/C a bit diminished or a bit stinky? A new filter could help! Plus it helps keep everyone in the car a little healthier.It should be replaced every two years for optimal performance and usually gets done at the same time the brake fluid is replaced. Here’s a comparison picture of two filters, one old, dirty one and a new one. Which would you rather breathe through?
