There are many varieties of mosquito coils on the spot, and the fragrance types are abundant. There are osmanthus fragrance type, sandalwood type, green tea fragrance type, and unscented type for consumers to choose.
 
There are two types of osmanthus fragrance: smoked and smokeless, both of which have a faint osmanthus fragrance, but the smokeless type is more recommended, with less smoke stimulation and a better use experience. Bamboo charcoal, smokeless and fragrance-free mosquito coils, and Er'ankang smokeless mosquito coils are all incense-free mosquito coils, using high-quality carbon black, which burns stably and has a long-lasting effect. The amount of smoke produced by the lit smoked mosquito coil is more than that of the smokeless mosquito coil, and it is not recommended for patients with respiratory diseases, the elderly, and children.
 
The active ingredient in all the incense is the common cyfluthrin at present, with a content of 0.05% and 0.08%, of which the content of cyhalothrin in the bamboo charcoal smokeless mosquito coil is 0.05%, and the content of the rest is 0.08%, and the effect of flufluthrin in repelling mosquitoes is better, and the side effects on the human body are smaller.
 
The punctual mosquito coil deodorant is strong and not easy to break, and it can be split by a light beating, which is also one of its major advantages. The combustion is stable and even, the time is 8 hours, the shelf life is three years, and it can be used in bedrooms, study rooms, and living rooms. The packaging is divided into boxes and barrels, but they are all paper packets, and the moisture resistance is slightly worse.
