The Winix NK100 and NK105 air purifiers provide excellent air purification in a modern design. They feature a 4-stage filtration system that utilizes an all-in-one, 360-degree filter and PlasmaWave® technology. The filter includes a pre-filter, a Coated DeOdorization (CD) carbon filter and a True HEPA filter. The pre-filter is the first layer of filtration that captures larger particles, like hair, and it helps to extend the life of the filter. The second level of filtration is the True HEPA filter that captures 99.97% of particles down to 0.3 microns, including dust, pet dander and mold. The final layer of filtration is the CD carbon filter that provides protection against VOCs and stubborn household odors. PlasmaWave® technology neutralizes viruses, bacteria, VOCs, odors and gases without emitting harmful ozone into your space. These 4 elements combine to provide superior air filtration within your home, ensuring the air is clean for breathing. The NK100 and NK105 also feature an air quality monitor that senses the room's current air quality and notifies the user via an LED light—red light means the air quality is poor, yellow light means the air quality is fair and the blue means the air quality is good and purified. SmartSensors within the NK100 and NK105 will automatically adjust the fan speed if necessary to purify the air. Includes a manufacturer's limited 2-year warranty.
