Whynter A/C Intake Filter

thingiverse

Whynter air conditioners work great but need an intake filter to keep dirt/dust/bugs out of the unit and keeping the condenser heat exchanger clean. Whynter sells a filter for the intake but it's like $35 for $1 worth of materials. Print two of these and use a fine nylon mesh like a paint strainer bag. Use super glue and glue them together with the nylon mesh in the middle. Insert the filter on the machine side against the mesh on the intake.
