944 Cabin Filter - Another variant
Posted: Tue Feb 11, 2025 10:13 am
I saw the PLA printed screens here on carpokes that would take 4.5mm filter to make a cabin filter. That is probably the slickest variant for a cabin filter apart from the fact that I am in FL and things tend to get pretty hot.
All the other variants had some things I didn't like (paper elements-bad if they get wet/944online filter protrudes into wiring / thermocouple / actuator space , etc etc).
Here is my variant.
I used M4 stainless hex screws (M4 x 20) and locknuts as studs mounted on the OEM screen. Then I bought some stainless steel mesh for $7 on amazon. This allowed me to sandwich a 1/2" thick polyester electrostatic filter material in between the OEM screen and the stainless steel mesh. The "stud" is locked in place with washers and a nut; the stainless steel screen is captured between nut and locknut with washers on both sides and the studs punched through the material. Nothing will get sucked into the fan, filter material is waterproof and not paper, and easily changed, and nothing protruding outward.
