The Reme Halo is not a conventional UV lamp. It is not simply because of the innovative design, it is also because of the ability of the Reme Halo to actively improve the air quality in your home. Most home air cleaning systems are passive or not very effective at seriously reducing pollutants. This is why the Reme Halo was designed to be better. It uses proprietary technology as well as an advanced UV light to improve the quality of the air inside your home. Low levels of hydrogen peroxide are created by our product to circulate through your system to gently clean it. The Reme Halo kills bacteria, viruses, odors and mold spores in the air and on surfaces in your home. It Meets the California ozone emissions limit.
