I want to replace my air filter with an upgraded unit that has carbon activated in it because of the wildfire smoke in the air, and I don't want to breath ICE effluence. I got access to the air filter, the manual instructions aren't entirely clear, do the following

  1. Open glove box
  2. Push sides of box inwards so that tabs clear and drop the box
  3. Push end of slow motion piston towards the box to release that end and drop box more
  4. The filter is behind a plastic door at the top of the area behind there (you have to get down to see it) - it's above the round air motor case

The OEM filter is a minimal dust filter that measures 8"x9.5" (I forgot to check the thickness which I will do), but it appears to be the same as used in many Chevy vehicles.

The FRAM CF10775 air filter appears to be one that will work, with carbon and Arm & Hammer. I'll get one and test.

Cool! I too would like a better filter option when the time comes to replace my air filter. Thank you for the writeup and link! Can't wait to see the review!

From the owner's manual, the process looks a lot easier then in the 2017 Volt. You needed a long hex socket as well as remove the right trim panel (required passenger door to be open) to remove the glove box and access the passenger compartment air filter.

ProfessroBolta thanks for investigating options for the cabin air filter. I'm definitely interested in the Bolt's air filtration system and look forward to your findings.

Thanks for finding this, Prof! I’m also interested is seeing how well this works. I just checked the filter, and it looks pretty dark. I’m sure a lot of it was caused by the recent smoke.

On a related note, my glovebox no longer springs back, when I pull it down too fast. A tiny hole in the back of the piston cured it. ?

Mine's still white, smoke was so bad I ran it recirculating the whole time :nerd:

Did you ever get the new filter?
Did it fit?
Aggggg, due to the fire I had to have it shipped to my brothers house, but then the MP's let us back in so I canceled it and planned to reorder with delivery to the house. But in the meantime Amazon jacked the price up to $30, and I went whaaaaaaa? Meanwhile there's other ones just like that (same brand) that appear to be the same, but cheaper? On my list to figure out. I'll look into it today and place an order.

My few min of research leads me to believe the FRAM CF11966 is the correct fit.

According to gmpartsdirect.com the OEM Filter is "GM 13508023", if you go to FRAM.com that GM # returns FRAM CF11966 as the (Arm&Hammer w/Carbon) replacement.
Good catch! And only $22, ordered. I'll have it on Saturday and will report back. Thanks -

Look forward to hearing the results. I too am interested in upgrading the cabin air filtration.
Coming in tomorrow, I'll post a full report. On the one hand there's not much that can be done with such a small filter, what you really need is lots and lots of filter square footage. The best you can get that I found is from IQ air, it's a Swiss company that produces high-end room air filters*. They have five stages of filtration and a filter stack is about 4 feet long. But in the Bolt we typically recirculate the cabin air which does have a better cleaning effect. I wish they offer the option of an upgraded filter stack, putting a couple carbon filters and HEPA filter after the stock does filter would do wonders. At any rate without getting some kind of 12 V aftermarket cabin filter this is the best we can do I think.

* It saved my butt during the fires, the house was filled with smoke and I ran my filter around powered by the Bolt. Cleaned up the air so well we are able to sleep in the house at night.

Main thing is it fits. I'm getting one for my next filter change. Thanks, ProfessorBolta!

Yup, fits perfectly. Quite a bit heavier than the OEM, I did a brief test in the garage, airflow seems unchanged, air seems cleaner. Hard to say but yeah I think it's a worthwhile upgrade.
Just to be clear, are you talking about the FRAM CF10775 or the FRAM CF11966 mentioned by NY-Rob?

The OEM looks pretty minimal, just coarse dust, but at that I was surprised to see how much crud it had collected in just a few weeks. Mainly I'm hoping the carbon can cut down on the exhaust, I hate the smell of ICE

Perhaps some day driving an ICE vehicle may arouse the same ire as an annoying cigarette smoker...

Ever since a kid I've absolutely despised the noise and the exhaust. Particularly hate guys who think its great to take the mufflers off and disturb an entire community with that nonsense. Can you image what cities will be like filled with BEV's? I hate cities just for one reason.

We have one of those ricers as I like to call them. It's so loud and the guy races up and down like it's a drag strip sometimes. It's very annoying indeed. He dogs that car so bad though I doubt it will last. My father said I should let a wagon roll down my driveway when he comes flying up the road....but that just isn't me.
