The Atem Car accessory kit equips your Atem to purify any car cabin of common interior particulate pollutants with HyperHEPA filtration designed for small spaces. As part of the modular Atem 5-in-1 personal air purifier design, this kit can easily transform your Atem into a fully functioning car air purifier using a specially designed three-armed mount and adjustable mounting belt with an easy-to-use buckle that can be attached and tightly fastened to numerous points throughout your vehicle to ensure a safe and secure source of clean air for your entire drive. The included car power adapter is compatible with both standard vehicle auxiliary DC power outlets and USB outlets, and Atem powers on and off accordingly when connected to vehicle power. Atem Car is also compatible with the optional HyperHEPA Plus particle, gas, and odor filter, which uses an additional layer of activated carbon material to adsorb common gaseous pollutants and volatile organic compounds (VOCs) found in high concentrations in vehicles from vehicle and industrial emissions, smoke, combustion particles, and 200 chemicals offgassed from interior car components, including formaldehyde.
