Our innovative room air purifier offers a simple, cost-effective way to improve the quality of your indoor air in almost any room in your home. The air purifier combines three different filtration technologies to create healthier indoor air. First, a pre-filter removes large airborne particles like dust, dirt and pet dander. Then, an advanced high-efficiency filter captures over 99% of particles sized 0.3 microns, including pollen. Finally, an activated carbon filter removes odors from your room’s air. The air purifier has a built-in air quality monitor that continuously samples incoming air and measures levels of pollution. The monitor has an easy-to-read LED screen that also changes colors based on the four different air quality grades displayed. Blue for good air quality, green for moderate air quality, yellow for unhealthy air quality and red for very unhealthy air quality. To improve the quality of the air within your room, you can increase the fan speed setting or switch to the auto mode which allows the air purifier to automatically adjust the fan speed based on the detected air quality.
