What are the main differences between air purifiers and fresh air systems?portable air purifier comp

　　The word "smog" is familiar to everyone. With the continuous development of industry, 70% of China's cities are shrouded in the shadow of smog. Everyone remembers the harm of smog to the human body. People who pursue a healthy life are dazzled by the air purifiers and new air systems on the market. Many users mistakenly regard the fresh air system as an air purifier, thinking that they just changed the name.

　　But the fresh air system has nowhere to redress the grievances, and can only shout loudly: we are different, we are different!

　　What is a fresh air system?

　　The fresh air system is an independent air treatment system. The fresh air host passes the outdoor fresh air through primary filter, intermediate filter, advanced filter, etc. to filter out dust, CO2, formaldehyde, PM2.5 and other pollution sources in the air through the pipeline to the closed Indoors, at the same time, exhaust the dirty, low-oxygen air indoors.

　　In addition, it can also remove the long-term sustained release of harmful gases after decoration, which is beneficial to human health; avoids "air conditioning disease", avoids home furnishings, moldy clothing, and even more negative oxygen ions, which provides fresh motive power for healthy breathing of the human body, without turning on The windows can also enjoy fresh air, adjust indoor humidity, and expel bacteria and other functions.

　　What is an air purifier?

　　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.

　　Air purifiers are used in the home, medical, and industrial fields. In the home field, stand-alone household air purifiers are the mainstream products in the market. The main function is to remove particulate matter in the air, including allergens, indoor PM2.5, etc., and it can also solve the problem of indoor, underground space, and air pollution caused by volatile organic compounds in the car due to decoration or other reasons. Since the release of air pollutants in a relatively closed space has the characteristics of persistence and uncertainty, the use of air purifiers to purify indoor air is one of the internationally recognized methods to improve indoor air quality.

　　Air purifier manufacturers believe that the difference between the two is reflected in the following aspects

　　1. Different purification effects. The purification effect is self-evident, and the air purifier is definitely more advantageous than the fresh air system. The air purifier will purify the existing air in the room. It belongs to the internal circulation and purifies the internal space. In a relatively closed space, by using the purification technology in the air purifier to filter or decompose the formaldehyde in the indoor air, Bacteria and other pollutants can disinfect and purify the air.

　　2. The core of the air purifier is the filter material. Some filter materials are good at filtering pollen, and some are dedicated to removing particles. If used improperly, the air purifier may become a "pollution source". Each purifier has several layers of filters with different functions. If the filter is dirty, it cannot be cleaned with water and must be replaced. The filter needs to be replaced frequently, even if the air quality is good, it should not exceed half a year, otherwise harmful substances will be released after the filter material is saturated and become a "pollution source". The use of air purifiers can reduce the degree of pollution to a certain extent, but it does not mean that air pollution can be fundamentally eliminated. Consumers should not be confused by various concepts when choosing an air purifier. Air purifier manufacturers recommend using Yaneng air purifiers, wash them regularly, and use a brand new air purifier every time.
