Silent, virtually odor-free, and with no open flame, Thermacell’s MR450 Mosquito Repeller effectively repels mosquitoes and other insects by creating a 15′ x 15′ zone of protection while camping, hiking, or hunting. It’s an essential piece of gear for bug-free fun outdoors.
With rubber-armored construction, re-engineered grill for better air flow, and ergonomic design, the MR450 includes 3 original Thermacell repellent mats that last for up to 4 hours each. It uses Thermacell butane cartridge refills for increased mosquito repellency, each lasting up to 12 hours. It also features an LED zone indicator that shows when unit is up to temperature and emitting the zone of protection, and will automatically turn off when temperature falls below optimal level.
Evaluated by the Environmental Protection Agency for safety and effectiveness.
