The Comfort First Filtered Diffuser™ is an enhanced diffuser with a built-in air filtration system. It offers four-way airflow and the ability to adjust the angle the air enters the room on all four sides; one side can blow down at a 45-degree angle, two sides can blow straight out, while the fourth bounces off the ceiling, or any configuration desired. Energy savings is achieved by the diffuser providing superior air distribution, which creates a consistent temperature throughout the room, the company says. This allows the thermostat to increase or decrease 2-3 degrees while maintaining a comfortable ambient air temperature. According to the manufacturer, each degree can save as much as 5 percent of building cooling-heating costs. The four electrostatic air filters cover each discharge point on the inside of the diffuser, filtering air as it enters the room and removing pollutants as small as 0.3 microns, including many mold and mildew spores, bacteria, pollens, and other pollutants. The filtration system features a quick-release design for fast and easy filter replacement.
