Working principle of air purifier

With the continuous development of the economy, people’s lives are getting better, but at the same time the air quality is getting worse, and there are more and more impurities in the air. People cannot breathe fresh air, so an air purifier is needed at this time. Olansi air purifier allows you to breathe fresh air and protect your health.

The air purifier is mainly composed of a motor, a fan, an air filter and other systems. Its working principle is: the motor and fan in the machine circulate the indoor air, and the polluted air passes through the air filter in the machine to remove various pollutants. Or adsorption, which continuously ionizes the air to produce a large number of negative ions, which are sent out by the micro-fan to form a negative ion airflow to achieve the purpose of cleaning and purifying the air.

The main principle of the passive air purifier is: the air is drawn into the machine with a fan, and the air is filtered through the built-in filter, which can filter dust, odor, toxic gas and kill some bacteria. The filter is mainly divided into: particulate filter and organic filter. Particulate matter filter The air purifier is divided into coarse-effect filter and fine particulate matter filter.

The quality of the fan and filter of this type of product determines the air purification effect, and the location of the machine and the indoor layout will also affect the purification effect.

The fundamental difference between the principle of an active air purifier and the principle of passive air purification is that the active air purifier gets rid of the restrictions of the fan and filter, instead of passively waiting for the indoor air to be drawn into the purifier for filtering and purification. Instead, it effectively and actively releases purification and sterilization factors into the air, and through the characteristic of air diffusion, it reaches all corners of the room to purify the air without dead ends.

The technologies for purifying and sterilizing factors on the market mainly include silver ion technology, negative ion technology, low temperature plasma technology, photocatalyst technology and plasmaplasma group ion technology. The biggest defect of this type of product is the problem of excessive ozone emission.
