Haoting was also founded in 2014, the company is headquartered in Tangshan, Hebei Province, the products mainly use OEM assembly production mode, and there is no direct factory. Haoting has unconventionally started the business of "channel sinking", focusing on the second, third and fourth-tier markets in order to avoid fighting in the fiercely competitive first-tier cities, and in addition, Haoting has also opened an online official flagship store.
 
Haoting's products take into account both wall-mounted and cabinet-type fresh air fans, and the wall-mounted type mainly includes three models: Fresh Air Treasure, Zhijing, and Zhizhen, with a maximum fresh air volume of 135m³/h, and the overall performance is mediocre; Zhijing and Zhizhen are both high-end wall-mounted machines, with a maximum fresh air volume of 350m³/h, a four-stage filtration system, and a full heat exchanger, with a heating efficiency of 65%, and the performance parameters are medium to high, with a price of nearly 20,000 yuan, and the cost performance is average.
 
The 500 series cabinet fresh air fan is also the main product of Haoting, derived from 500S, 500L and 500U models, the price ranges from 9700-18000 yuan, and the maximum fresh air volume is 500m³/h. In terms of materials, the 500S uses ordinary domestic motors, while the 500L and 500U use German EBM motors; The filtration system of the three is also relatively thick, the grade of the HEPA filter is H12, 500U is the highest priced model, the HEPA filter is the thickest, with an unfolding area of 8 square meters, and an activated carbon filter layer, and the electrostatic dust collection function is not absent, and the two can effectively cope with the severe haze environment with each other.
 
Breath treasure is a unique function of Haoting different from other brands, the general fresh fan mainly through the micro positive pressure system, that is, the indoor air pressure is slightly higher than the outdoor, so as to squeeze the dirty air out of the gap, and Haoting's breathing treasure is essentially an auxiliary exhaust fan, which can be installed at the opposite corner of the fresh fan, which can promote indoor air circulation and speed up the rate of fresh air entering the room, but each time one more breathing treasure is installed, it is necessary to punch an additional wall hole, and the acceptance of the general owner is not high.
 
In general, Haoting's product performance is acceptable, but there is still a large gap with first-line brands in terms of workmanship details, performance parameters, brand building and offline services.
