In winter, as the weather gets colder, in order to keep warm, in addition to conventional heating facilities, people will also use air conditioning, heating fans and other heating equipment to ensure the temperature of the room.

The air purifier consists of a motor, a fan, an air filter, and other systems. It works as follows: a motor and a fan in the machine circulate the air in the room, after the polluted air passes through the air filter net of the machine, the various pollutants are removed or adsorbed, the air is continuously ionized, producing a large number of negative ions, which are sent out by the micro-fan to form a negative ion air stream, thus achieving the goal of cleaning and purifying the air.
In daily life, bad indoor air can lead to physical discomfort and poor health (such as headache, itchy eyes, dyspnea, skin allergy, fatigue or vomiting), and in the working environment, it will lead to high absenteeism and low production efficiency.
