It has a rechargeable battery for use with or without AC power. Just load the compact machine with an industrial odor neutralizing cartridge and turn it on. Cartridges are rated for up to 270 hours of service. After initial restoration, pleasant aroma secondary cartridges may be used to diffuse a scent into the area.Once fully charged, The Restorator Duo provides approximately 18 hours of use. It can also be used while charging.Vaportek odor control systems provide immediate odor neutralization in situations where other methods may fail. These systems incorporate natural, non-toxic essential oils and odor neutralizing compounds in patented membrane cartridges that breathe a penetrating dry vapor into the air. Unlike fogging and ozone treatments, Vaportek products can be used in occupied structures. They will not harm people, plants or animals, or affect fabrics, rubber, adhesives and other materials and surfaces. The systems have been proven effective in fire and flood restoration, industrial and healthcare facilities-even in eliminating difficult-to-remove urine odors.Cartridges:For odor control/restoration situations:AR39 - Vaportek 3X Industrial Cartridge - Neutral ScentAR39S - Vaportek SOS Cartridge - Smoke Odor SolutionsFor general deodorizing and pleasant aromas:AR48A - Vaportek Cartridge - Neutral ScentAR48B - Vaportek Cartridge - Berry ScentAR48C - Vaportek Cartridge - Lemon ScentAR48D - Vaportek Cartridge - Orchard ScentAR48E - Vaportek Cartridge - Forest ScentAR48F - Vaportek Cartridge - Cinnamon ScentAR48G - Vaportek Cartridge - Lavender ScentReplacement battery: AR45BReplacement charger: AR45C
