How does my 3D comfort operate?

The 3D Comfort will take in the existing room air, pass it through a HEPA-type filter, removing  99.9% of allergens and pollutants and expel the fresh purified air back into the room. When the unit is in heat mode, the same process will occur, except the air will pass over a heating element expelling warm air back into the room.
