How Does the Mijia Smart Mosquito Repellent 2 Work?

The Xiaomi Mijia Mosquito Repellent 2 is a game-changer in pest control. Crafted from eco-friendly materials, it ensures both safety and durability.

Its compact size and independent operation make it incredibly versatile, fitting seamlessly into any space or accompanying you on travels.

Designed for rooms up to 28m3, this repellent uses a metofluthrin-based repellent which lasts an impressive 1080 hours, providing protection for the entire summer.

What sets this device apart is its intelligent features. You can control it effortlessly through the Mi Home App which comes with a 10-hour timing mode for energy conservation.

The built-in fan ensures uniform volatilization, outperforming traditional methods and even does a better job than its predecessor the Xiaomi Mosquito Repellent (1st gen).

In short, you place the repellent sheet in its compartment, insert the battery and turn on the device. Once the fan powers up, it will convert the liquid on the repellent pad into vapor which will get dispersed around the room.

How Xiaomi Mosquito Repellent Works

How Xiaomi Mosquito Repellent Works

Xiaomi has mastered the art of producing smart products that are affordable and stylish and mosquito repellent is no exception. 

  • The Xiaomi mosquito repellent is an eco-friendly device that is simple and convenient to use. This latest version is equipped with a non-heating, fan-type mechanism that is odor-free and smoke-free. It's one of the latest gadgets by Xiaomi. In fact, Xiaomi has started launching solutions to combat health-related issues on the planet.
  • The Xiaomi mosquito repellent uses battery-driven fan-type evaporation. This is different and more effective than the traditional heated type mosquito repellents. This also means better battery life and portability. The device consists of openings on the top and bottom to effectively repel mosquitoes and other bugs. The placement of the fan below the repellent tablet is intentional as it dispenses the medicine effectively. 
  • The film on top is manufactured by the Chinese subsidiary of Aspen pharmaceutical ltd. The film uses a honeycomb design that helps volatilize the medicine in the repellent tablet.

The medicine used is called transfluthrin and each tablet contains 500 mg of the medicine. Another interesting aspect is a button battery that is built into the repellent sheet which records how much medicine is being used at any given point. Cool, right?

Design of the Xiaomi Mosquito Repellent

Xiaomi has maintained the same design minimalistic scheme with the Xiaomi Mijia Mosquito repellent. It is completely white in color with a slightly grey top cover. As far as the texture is concerned the body is smooth to the touch whereas the top cover has a matte finish.

  • This mosquito repellent looks quite nice and easily blends into the environment without standing out. So it can easily be used in any room you see fit. It's also quite small, only weighing about 133 grams. As mentioned earlier, the entire external casing of the Xiaomi Mosquito repeller is made of an ABS + PP material which is environmentally friendly.
  • Xiaomi's Mosquito repellent is essential and comprised of three layers. The top grey portion is removable and is used to access the mosquito coil slot. This top portion also functions as a non-slip pad and is made of organic silicone.
  • When we come to the middle portion, which is the body of the device. It contains a mosquito coil slot and a fan below it. Although the coil fit in perfectly without any gaps, it is quite a nuisance to pop it out.
  • Below the fan, you'll find two slots for batteries. You can only access these slots by twisting the lower panel.

The Xiaomi repellent coil itself is proprietary. It uses a honeycomb design to volatile the chemical. This repellent is designed to be as effective as possible. Especially with the addition of the fan and the mesh holes at the bottom.

Mosquito Repellent Review - Key features

  • The Xiaomi Mosquito repellent is about 133 grams which makes it ultra-portable and an ideal companion for a modern home. The exterior is made from a combination of ABS plastic and PP. So, not only is it sturdy but it is also environment friendly.
  • The mosquito repellent is odor-free, smoke-free, and noiseless. It is also equipped with a LED status feature that alerts you if the device is running in the normal mode or the timing mode. This LED feature also alerts you if the repellent needs to be changed or if its time to change the battery. Honestly, it's super convenient.
  • The product is easy to operate and takes two steps to change the tablet or batteries. The battery life lasts up to 35-45 days dispensing on the usage. Most importantly, it has a feature that is built into the mosquito repellent itself that tracks the time of use of the repellent.
  • The repellent tablets last up to 90 days when used with the timing option of 8 hours a day. The mosquito repellent film on the product uses a honeycomb design that helps dispense the repellent effectively. These tablets are produced by a Chinese subsidiary of the Japanese Ash Pharmaceutical Co. Ltd, which is known to use powerful hive designs and tetrafluoride to achieve the highest level of effectiveness and efficiency.
  • Each repellent contains up to 500mg of tetrafluoride and other chemicals. So, it is considered relatively unsafe and toxic to humans as well. While Xiaomi states that it has the certifications of various safety agencies and that it doesn't pose any risk to humans. It's still best to not stay in the room when it's running. Most importantly, it should not be running near a baby.

How Xiaomi Mosquito Repellent Works? - What’s in it for you?

The Xiaomi mosquito repellent is a portable, easy-to-use repellent with useful features like LED status and timing mode. The wireless design lets you carry it anywhere and the long-lasting batteries make it a must-buy for homes.

  • The coverage area is a matter of concern but it makes up for its effectiveness. It not only repels mosquitoes but also small bugs like moths and flies.
  • The material used is eco-friendly and does not produce odor or smoke which is a big plus. The repellent is kid and pet friendly though it’s advisable to not use it around infants. The inbuilt fan has an excellent capacity to ensure volatile dispensing and greater repellency. 
  • The product is wireless and comes with extended battery life due to the smart timing functionality. 
  • Different from the traditional heated volatile mosquito repellent, Xiaomi mosquito repellent uses the battery-driven fan-type evaporation. The evaporation of mosquito repellent tablets is effective and it can be used for about 90 days if it is used for 8 hours a day. 

The only drawback I felt is the availability of the repellent tablets. These can only be purchased online and you might have to plan in advance. The fact that they last up to 90 days makes life a little easier. I can personally vouch for the battery and repellent tablet life. The LED status does remind you of this though. Now, that’s some smart technology at work, isn’t it?
