DIY Cabin Air Filter

[jpadua]

Hey guys, I also made a DIY filter from simple materials, might be cheaper. You can also replace the filter element. The one I made is a bit crude but it works hehehe , but I'm planning to build another one but this time instead of cardboard I'll use plexiglass, but this will do for now.

Materials:
Aircon filter and nylon screen which you can purchase at any home/hardware store

Small cardboard giftbox which is roughly about 7" x 9" x 1"

How I built the aircon filter holder:

1. Cut out 1" from the long side of the box.
2. Re-enforce the box flaps with elmers glue
3. Cut out a hole about 1" from the sides in the middle of the box and the lid
4. Cut enough nylon screen to cover the hole on both the box and the lid
5. Staple the nylon screen to the box and lid, then reinforce with some Masking tape
6. Reinforce the box with more masking tape
7. Cut a piece from the aircon filter just enough so that it can fit inside the box

You will have something like this:



8. Place the aircon filter on the box


9. Place the lid upside down so that you will have a screen-filter-screen sandwich.



Installation:

10. Remove the glove box.



11. Remove the aircon filter cover.



12. Insert the DIY filter lengthwise.



You will have enough filter material, for several replacements.
