The patented Mitsubishi Electric Dual Barrier Coating prevents dust and dirt from accumulating on the indoor unit – keeping it cleaner year-round.
Dual Barrier Means:
The coating is applied to the heat exchanger, vanes and ducts, and to the blower wheel of the indoor unit, which means reduced labor intensive maintenance.
Collects 1/10th of the dirt compared to non-coated components after 10 years of no cleaning maintenance.
