So...did I install the filter in the wrong way!?! Really confused now.

Air Flow is down as the arrow on the filter shows
I replace mine once a year in the spring

Has anyone seen or used the Cleenaire Cabin filters? CAF7277 ? Cleenaire . I found them on Amazon for $13. I'm thinking I'm going to try it out.

Good info here. Can't wait to get a this m37.

New filter on the left, old on the right. You can see the Cleenaire fins are much thicker and carbon infused. I think it's definitely worth $13 replacement.

I also went with Cleenaire CAF7277

After hearing about it on these forums. The filter is definitely worth it. Im actually surprised about the price. The material is a lot thicker than OEM and it has a good amount of carbon.

I stopped using the Cleenaire filter because it's ever so slightly smaller than the factory filter and I could hear it moving around sometimes when the a/c was on. The tech package filter blocks airflow somewhat. Just bought this for $23. It has the same activated carbon and polyphenol as the tech package filter. Purolator: PurolatorBOSS® Part number for the G37 is PBC25870

Amazon sells charcoal activated filters for 12 bucks

But none of them have polyphenol. I do notice the improved airflow with the Purolator Boss compared to the tech package filter and it's half the price. I'll be buying this from now on.
