an inverter-driven fan motor to deliver the most quiet & powerful performance

What it Means:
PlasmaPure employs an inverter-driven fan motor to deliver the most quiet & powerful performance possible. The inverter-driven motor ramps the RPM's up or down, creating multiple fan speeds automatically. Most air purifiers offer only three set speeds as follows: LOW, MED, HIGH. PlasmaPure is powerful as well as quiet. Mitsubishi has designed the PlasmaPure models to be among the safest and most reliable air purification systems on the market.

How it Works:
The mini-blades on PlasmaPure's sirocco fan are engineered to produce powerful yet quiet air distribution. PlasmaPure model MA-EF503 moves up to 160 CFM (150 CADR, Clean Air Delivery Rate for dust) and is suitable for rooms up to 233 square feet. The model MA-EF303 moves up to 106 CFM (100 CADR) and is suitable for a room up to 155 square feet. The sound level produced by the fan on MIN speed is incredibly only 36 dB(A). To compare, a whisper is only 30 dB(A). Even on HIGH the sound level is a respectable 53 dB(A). The risk of electrical shock is greatly minimized by a series of power disconnect switches located at the grill, HEPA filter, and charcoal filter. If any of these components are removed, the power supply is automatically shut off, unlike most other units we tested, which continued running even with the grill and filters removed. If airflow is greatly restricted due to excessive caking of dust on the HEPA filter or if the unit is left running while face down on carpet flooring, the microprocessor's current-watch system tells the transformer to stop the electrical current. If power to the unit is interrupted, the unit returns to its former operating mode after power is restored.
