Cabin filter Mann or OEM Mazda

I went with the Mann filter to get Polyphenol for mold and bacteria protection along with the carbon.

This Mann cabin air filter is probably the best one I’ve ever used. I could be behind a diesel truck and smell nothing but clean air.

Go on amazon and look for a Mann Frecious Plus filter, its as good as it gets

I switched over to Mann biofilter and had positive results esp w/ smells.

I really love the new filter I got. Its more expensive than OEM though. The thing about the new filter is it has both carbon and a polyphenol coating. I noticed that when my engine shuts down during start/stop that the air con doesnt have a wet dog smell anymore.

The second replacement filter was a Mann activated charcoal filter which does seem to help keep the interior smelling even fresher.

What finally seemed to help was replacing the cabin air filter (did myself in 3/2017) with one of the MANN charcoal filters (FP26 009 "Frecious Plus"). Perhaps this was just coincidental, but we have not experienced the problem since changing the filter.

You can get the engine and cabin filters on Amazon and save yourself $150+ dollars. Look up Mann filters (which is the same thing VW uses) for you year.

I thought the real issue was the fact that the Atlas cabin filter is just paper, whereas they used to use carbon filter in other, older models. Thus, all outside smells can easily be entered into the cabin.

Cabin air filter, first gen Mazda 3. Getting to the filter is a pain.
