Features

The Thermacell MR300 Portable Mosquito Repeller is a compact, fuel‑powered solution designed to create a 15‑foot protective zone against mosquitoes in outdoor environments. Using a butane cartridge to activate the system, the unit heats replaceable repellent mats to disperse a scent‑free vapor that forms an effective barrier in the air. The design eliminates the need for sprays, lotions, or open flames, providing clean, quiet operation suited for hunting, camping, and general outdoor use.

The MR300 features a quiet ignition system, reengineered grill and switch, and improved ergonomics for reliable, user‑friendly performance. The included camouflage cover adds concealment in field conditions, while the lightweight construction supports easy transport. Each repellent mat provides up to 4 hours of protection, and the system includes a butane fuel source for extended use. Built for simplicity and effectiveness, the MR300 delivers consistent mosquito control without residue, smoke, or direct skin application, making it a practical addition to outdoor gear setups.
