Hi All,

Just a quick post on finding the 2nd, bigger cabin filter for our 991's. Searched high and low and couldn't find a definitive post so here's mine.

It's a 10 minute job. First, glove box removal is NOT necessary. If you stoop and look under the glove box, there is a foam cover held on by 3 plastic screws. You only need remove the screws and foam cover and the door of the Cabin Pollen filter is now accessible. Open door, pull out filter and replace! Voila!

 

Bigger Pollen Filter

 

foam cover held on with plastic screws

 

Here's the Door with the Foam over peeled back...I only removed the two screws and was able to access.

 

Nice!! Good find and thanks for sharing.

 

Don't forget about the second air filter in the frunk which is even easier to replace...

 

How often is it recommended to change these out? Do they get changed during the standard service? Should we be doing this in addition to the standard service intervals?

 

Nice work. Thanks for sharing!

 

I have 17,000 miles & changed both filters. Yes, the smaller Frunk filter was a piece of cake & the filter actually came with a pictoral on how to change. The bigger filter had zero. I only knew it was somewhere near glove box.

The bigger filter was not nearly as dirty as the frunk smaller filter. I plan on changing every year, a small cost for clean cabin air.

 

Where did you source the filters?

 

Porsche has published a service booklet with details...

 

I went thru Pelican Parts...The pollen filter was"Micron" brand and when compared to the original...looked eerily similar at 1\4 the price.

 

Thanks for posting

 

Nice...thanks!!

 

Very nice info and pics. Thank you for posting!
