The LIFAair LAH302 air purifier + humidifier is a combo cleaning unit designed to keep us healthy from difficult climates, pollution, and overactive immune systems, to name a few. People with allergies and other breathing sensitivities will appreciate this combo that helps maintain optimum fresh and clean air levels indoors while also managing the humidity during pollen season, hot summer nights and other challenging climate-related issues. The LAH302 uses a top-mounted OLED high-definition display that showcases indoor air quality readings at a glance including indoor temperature, water level, and operating status. At the same time, it is equipped with an ambient light sensor to automatically adjust the brightness of the screen backlight to avoid light pollution.
