Fresh the air continously and clean it.
Professional muffler cotton is attached inside the case to reduce noise and silently convey fresh air.

On June 28, 2005, WAO and allergy agencies of various countries jointly launched a global initiative against allergic diseases, and designated July 8 as World Allergic Disease Day. The aim is to prevent allergic reactions and allergic asthma by enhancing people’s awareness of allergic diseases.
The epidemiological survey of allergic diseases in 30 countries by the World Allergy Organization shows that 22% of the total population in these countries suffer from allergic diseases, such as allergic rhinitis, asthma, conjunctivitis, eczema, food allergy and drug allergy. About 40 to 50 million people in the United States have allergic problems, of which 39.5 million have seasonal allergic rhinitis. According to the estimation of the World Health Organization, there are 150 million asthma patients in the world, and the trend is increasing year by year, among which 50% of adults and at least 80% of children are caused by allergic factors such as pollen. Without treatment, 25%-38% of seasonal allergic inflammation will develop into asthma and eventually become perennial asthma, emphysema and pulmonary heart disease. The World Health Organization also estimated that more than 180,000 people died of asthma every year, and about 250,000 people died of asthma in 2005.
The global expenses related to allergic rhinitis, including drugs, consultation and work vacation, cost more than 20 billion US dollars every year. The global expenditure on anti-allergic drugs alone is estimated to exceed $8 billion.
If the home has just been renovated, the fresh air system is very necessary! After decorating the new house, the emission period of harmful substances such as formaldehyde will not end in one year or two, even if environmental protection materials are used, it is inevitable.
In the face of smog and dusty weather and newly renovated houses, fresh air ventilator can reduce the impact of particles and dust on daily life.
Fresh air ventilator is an air conditioning equipment that provides fresh air, which is mainly composed of air inlet, motor, fan, filter, humidifier, air valve, air outlet and other components. Its main function is to send outdoor fresh air into the room through the fan, and replace the original dirty air when entering the indoor space, so as to keep the indoor air fresh and clean. Fresh air ventilator is divided into three types: bidirectional flow, purification system and total heat exchange system.
Two-way flow fresh air ventilator is a kind of “forced air exhaust, forced air supply” system, which is composed of a group of forced air supply systems and a group of forced air exhaust systems. Its working principle is to rely on the suction generated by the main engine to form indoor negative pressure, and send dirty air to the outdoor through the air supply pipe. In order to balance the indoor negative pressure, relatively fresh air outside the room enters the room from the pre-installed air inlet to achieve the purpose of ventilation.
The total heat exchange fresh air ventilator is an upgrade of the two-way flow fresh air ventilator. The total heat recovery system is added to the main engine. The air entering and leaving the main engine passes through the heat exchanger installed in the main engine, and the energy exchange of preheating and precooling is carried out, which can retain 70% of the energy of indoor air. It is very energy-saving when used in conjunction with air conditioners, and will not affect the indoor temperature even if the temperature difference is large.
AC motor: it adopts international pure copper motor with overheat protection. The high-speed rotation of the motor continuously provides strong power, which is stable, silent and energy-saving.
Heat exchange core:Adopt polymer nano heat exchange material +ABS engineering plastic frame+galvanized outer frame. It is designed in two sections, saving installation space and facilitating later maintenance. Additional filter protection, high air permeability, good air tightness, tear resistance and aging resistance. Moisture removal and mildew prevention. The heat exchange rate reaches 70%.
