Return Air Filters

  • Filter the air that is already inside to the Cabin. 
  • Capture any contaminants that come off the operator’s clothes & boots.
  • Prevent Dust and Fibres getting inside the OEM evaporator Coil.
  • OEM's Return Air Filter media may be low efficiency - Meaning fine Dust & Fibres may get through.
