ASPEN's newest air purifier releases with a unified goal of making your home air safe, comfortable, and cool. Pairing with our tower fan and window fan, ASPEN provides a relaxing home environment during those hot summer nights or pollen filled spring days. Purify your air and protect those around you from airborne pollutants. The ASP400 Air Purifier is the perfect fit for your bedroom, living room, or kitchen with its speedy and efficient filtering time. The 3-Stage HEPA Filter traps odors, particles, and other harmful microbes as small as 0.3 microns. Remove the annoyance of constant sneezing by filtering out dust, allergens, pollen, and more. The PM 2.5 sensor detects inhalable particles that is 2.5 micrometer or smaller. The sensor will trigger the ASPEN Smart Air Purifier to increase the fan speed when it in the Auto mode to quickly reduce the PM 2.5 particles in the air to reduce the risk of the harmful particle affecting our eyes, nose, lung, and skin. The LED on the Air purifier and in the App give you a quick visual what's current quality. Color: White.
