Review on Bosch Automotive 6026C HEPA Cabin Air Filter for Toyota Corolla & Matrix: 2002-2008 Models & Beyond by Michael Floyd

So this filter is advertised as HEPA. After becoming a user of the Fram brand, I decided to change a little and go for Bosch. If you've used Fram filters like me, I don't think you'll like this filter over Fram! I know they advertise HEPA and such but in comparison this thing is flimsy, flimsy and I wonder how much efficiency I can get out of it, only time will tell. But maybe you don't like it. I know this filter for sure, it's dirty, I'll change the brand again. The Fram filter is thick and beefy, it's not.
