　　What is the difference between a household fresh air system and an air purifier

　　Many friends don’t understand the use of a household fresh air system or an air purifier for indoor use, or who among them is useful. There is no clear understanding. What is the difference and function of the two?

　　The working principle of the air purifier is mainly to realize the mechanism of indoor air circulation through the operation of the fan. After the dirty air passes through the filter device, bacteria or large particles of impurities are removed or absorbed, thereby providing people with a "microclimate environment" of fresh air (the air purifier does not have the function of fresh air replacement).

　　1. The method of air purification

　　When is running, the air purifier adopts internal circulation adsorption filtration and purification, and the fresh air system adopts external circulation purification. Here, we can see a clear difference. Air purifiers mainly purify indoor air and cannot bring in fresh air.

　　2. Installation and use environment

　　The installation environment of the air purifier is flexible, has low environmental requirements, and can be moved at will. A fresh air system needs to be installed before decoration. Of course, there are also wall-mounted fresh air that can be installed later, but holes need to be drilled in the wall, which is more troublesome to install.

　　3. Air purification efficiency

　　The 　　 air purifier can quickly replace indoor and outdoor air, but it has limitations in application and is suitable for use in a separate room. If it is designated to be placed in a certain area, it will not help the purification of the entire room.

　　Compared with air purifiers, the fresh air system can purify and introduce outdoor fresh air to the air environment of the whole house, thoroughly the air efficiency of the whole house. In the purification process, since the fresh air system is mainly for the purification of the entire room, the speed is relatively slow compared to the specific area of the air purifier.

　　4. Price and power consumption

　　The price of fresh air system is slightly higher than that of air purifier. But the fresh air system has low power and low power consumption. Therefore, in order to circulate fresh indoor air, we can turn on the fresh air system for ventilation for 24 hours.

　　Through the above introduction of fresh air system and air purifier, it can be seen that there are differences between the two in terms of environment, efficiency, price, etc. In the purification operation mode, the difference is still very large, and you can determine the choice according to your needs.
