I believe that's too extreme with the recommended maximum replacement interval at 2 years or 30,000 miles on cabin filter. But it won't hurt to replace the cabin filter more often if you feel you can get better filtered air other than spending more money. But I was wondering if you replace your engine air filter that often as it breathes the same air.Oh I forgot...other people's environment is less dusty than mine. 10k and my cabin filter needs replacement. It depends on your environment. I go through 2 filters per every 10k miles.The cabin filter replacement is indicated at 10K miles?
Notice that the cabin filter came from factory is a charcoal filter which looks black and dirty even if it's brand new. Don't throw away too early by the look and you won't be able to get the same OEM charcoal cabin filter in the US as Mazda USA doesn't offer that for US customers.
