    This product requires a compatible outdoor condenser for functionality. For over 50 years, Mitsubishi has remained at the forefront of the mini split industry thanks to their dedication to providing efficient, user-friendly comfort solutions. The MSZ-EF12NAW-U2 is a wall mounted heat pump mini split indoor unit for use in multi-zone systems. This stylish slim design at a depth of only 7.69 inches, is paired with quiet operations that provide comfort without disrupting your space. Choose between 3 different colors to fit your home decor. With multiple operating modes, multiple fan speeds, and multiple airflow directions, this unit fits the needs of nearly any room.
  • Advanced Filtration System
  • The M-Series indoor unit combines a hybrid catechin deodorizing filter with an enzyme-based filter for managing allergens. The anti-allergy filter not only captures the offending particles, it also breaks them down, cleaning the air as it is conditioned.
  • Econo Cool Mode
  • By slowly adjusting the cooling set point and swinging the horizontal vanes, the M-Series indoor unit can improve the efficiency of cooling operations without compromising the comfort provided.
  • Dehumidification
  • When the indoor unit is run in dry mode, it removes unwanted moisture in the air. This improves comfort and reduces the chance of mold growth and other property damage in the conditioned space.
  • Smart Set
  • Mitsubishi's Smart Set function allows you to save a cooling profile consisting of a temperature, a fan speed, and an airflow direction. The setting range for HEAT mode is 50 degrees Fahrenheit.
  • Sleek Design
  • With a depth of only 7.69 inches, you can fit this indoor unit just about anywhere on the wall. With the options of black, silver, or white, this sleek stylish design can match any home decor.
  • Kumo Cloud Capability
  • The Kumo Cloud App allows easy access and control with any smartphone or internet browser.
  • Weekly Timer Operation
  • Have your unit turn on and off as you please. The M-series units allow for four on or off timers per day and a maximum of 28 per week.
  • Product Compatible With These Mitsubishi Outdoor Units
  • Product Note
    This product requires a compatible outdoor condenser and the following accessories for indoor unit installation:
    • Line Set - This double insulated tubing transfers refrigerant efficiently between your outdoor condenser and indoor units.
    • Drain Tubing - Drain tubing facilitates the reliable and effective removal of condensate from your system. It connects your indoor units to drain locations of your choosing.
    • Connecting Wire - This durable, insulated wire provides power to your indoor units from your outdoor condenser.
