Dettol is a brand of Reckitt Benckiser UK, focusing on the field of personal hygiene, and its disinfection and sterilization products are world-renowned and have become the products of the British royal family. Dettol has only two products in the face mask industry, but it is the first major manufacturer to use this technology in the exhalation valve with an electric ventilation system.
 
Dettol smart masks meet the U.S. N95 protection standard and have a filtration efficiency of more than 95% for non-oily particles. The nose clip is not adjustable, but it is equipped with nose pads to prevent the glasses from fogging up. The upper and lower headbands are equipped with locks that allow you to switch between neck and ear wearables. This model is tailored to Asian faces, and is available in three sizes, small, medium and small, suitable for children over 3 years old or adults with smaller faces, and can be purchased according to the size on the official platform.
 
If it only has the above features, this mask that costs about 20 yuan is just a decent mask, but Dettol adds a reusable miniature ventilator to its exhalation valve, which makes it different from ordinary anti-smog masks. The ventilator is facing away from the exhalation valve interface, and after it is locked, the power is turned on to continuously discharge the heat and water vapor in the mask, and the breathing resistance is much lower than that of a general mask when worn. However, this miniature ventilator does not come with the mask, and needs to be purchased separately, and the price of up to 200 yuan per mask makes the cost of using the mask rise significantly, which is suitable for consumers who are not sensitive to price.
 
Dettol's activated carbon mask can absorb odors, the filtration efficiency also reaches the N95 level, and it is equipped with an exhalation valve, but the cover body and face lack a fitting design, which is more prone to air leakage, and the headband has no adjustment function, which may cause discomfort. However, the price of 16 yuan / piece is still one of the cheapest activated carbon masks that can be bought on the market, and it is recommended for users who have been in an odorous environment for a long time to buy it.
