Review on FD811 White Cabin Air Filter 3-Pack for Mazda 3, 6, CX-5 - Replaces CF11811 and KD45-61-J6X by David Stover

My wife and I recently bought a 'new' SUV. One of the first things I check (as an ASE certified mechanic) are filters. I'll change the oil and filter right away so I know what's in the engine. That's the most important. Second, I always check the cabin filter. NOBODY forgets to regularly check and replace these filters. The result is poor air quality in the cabin. Sometimes it smells bad. Sometimes the outside airflow is greatly reduced by the lever, as it should be. And these filters are usually easy to change. They're right behind the glove box. A short YouTube video shows you how to change this. The cost is the minimum for the upgrade you will receive. These filters are great. Fit well and cheap. A tip: For better filtration, look for activated carbon filters. Each paper filter removes leaves and particles, and charcoal further reduces odors. I will not use anything other than activated carbon cabin filters.
