Thermacell EL55 Features The Thermacell EL55 Mosquito Repeller is engineered to precisely diffuse repellent creating a 20 foot zone of protection that reaches full effectiveness in as little as 15 minutes after activation. The active ingredient metofluthrin repels tough mosquitoes including species that may transmit Encephalitis West Nile Virus and Zika Virus giving users confidence during evening gatherings or time spent outdoors. Because the system works without DEET sprays or lotions applied directly to the skin it offers a scent-free smoke-free and flame-free way to stay protected. The repeller has been independently tested and reviewed by the EPA for both safety and effectiveness. A rechargeable lithium-ion battery powers the unit eliminating the need for disposable butane cartridges or replacement batteries while keeping the repeller ready for repeated outdoor use. The built-in light operates independently from the repeller function so users can run illumination mosquito protection or both at the same time depending on what the moment calls for. Audio cues paired with LED indicators communicate clearly when the zone of protection is active and how much battery life remains removing any guesswork during extended evenings outside. With its scent-free and smoke-free operation the Thermacell EL55 is well suited to patios campsites and backyard gatherings where comfort and reliable mosquito protection both matter.
