Thermacell MR300 Portable Mosquito Repeller Olive 15ft Coverage

The Thermacell MR300 Portable Mosquito Repeller creates a 15-foot zone of protection against mosquitoes without sprays, lotions, or scented chemicals. This compact device uses heat-activated repellent technology to provide up to 12 hours of continuous protection in outdoor environments.

What Makes This Different

Unlike topical repellents that require skin application, the MR300 creates an invisible barrier of protection through airborne repellent dispersion. The device operates silently without fans or moving parts, making it ideal for hunting, camping, and tactical operations where noise discipline matters. Heat-activated allethrin mats provide consistent coverage without the mess or reapplication requirements of spray-on alternatives.

Key Features

• 15-foot radius protection zone covers 225 square feet
• 12-hour runtime per butane cartridge with continuous operation
• Olive drab finish provides low-visibility profile for outdoor use
• Scent-free operation won't alert wildlife or compromise concealment
• No skin application required - works through area saturation
• Compact 4.5 x 2.7 x 6.9 inch footprint for pack portability
• Push-button ignition system for reliable field operation

Field testing demonstrates effective mosquito control within the coverage area under typical outdoor conditions. The device maintains consistent output in temperatures from 50°F to 95°F, making it suitable for extended outdoor activities across multiple seasons. Wind speeds up to 6 mph allow normal operation, though effectiveness decreases in stronger air movement.
