With just one device, users can enjoy a pest-free summer, sparing the hassle of frequent replacement. The repellent uses a built-in fan drive to help spread the repellent substances evenly throughout the room, with no need of heating. It works safely and efficiently in a maximum space of 28㎡. The fan (below 35 Db) makes very little noise, ensuring users a sound night’s sleep. It has a 10-hour auto shut-off timer mode and an LED status feature indicating both how much repellent fluid remains and the battery life of the device.
