DIY: Re-usable Washable In-Cab Air Filter Mod

Needed Materials:
- Adjustable Washable Furnace Air Filter (I used one from Home Depot). Make sure to get the adjustable one.


Needed tools:
- Scissors
- Utility Knife
- Drill

I have a 2012 Tundra which may have a slightly different size filter and slightly different way to access the filter from the glove box than <2011 and 3rd gens.

Start by removing the existing in-cab air filter. To do this open the glove box. Remove the shelf by pulling up.


As you can see, these filters can get very dirty if not replaced (or cleaned) regularly.


Remove the first access panel.


Remove the second access panel.


Remove the new air filter material from the plastic c-channel frame. Use one smaller and one larger c-channels and cut them to match the size of the existing filter.


Next cut the filter material and plastic grid to fit within the frame. Insert into the frame.


Then drill 2 holes in the corners of the frame and insert the provided plastic rivets in the holes to lock the frame together. The plastic rivets come in the package with the adjustable filter.


Final step is putting the filter back into the truck and putting all the pieces back in place.



Two in-cab filters can be made out of this one furnace filter. Got this idea from this same mod on a Tacoma.
