Inside Coach Air Condition Filter
Our two overhead Duo Therm air conditioners have a two-sided filter that I clean with a vacuum. One side is blue and much thicker. The other side is gray more porous and lighter. Which side faces down inside the motorhome floor? Does it matter? They are in good condition, so unless there is a much better filter available, replacement is not necessary.
Thanks
