In recent years, smog has become more and more serious, people began to worry about the health of themselves and their families, so air purifiers and fresh air systems have become more and more concerned about air quality products. But for these two products, what many people don't know is that although they are of the same kind, they are very different. If you still can't decide, let Xiaobian explain it to you one by one.
air purifier
The principle of the air purifier can be basically called “internal circulation”. The air purifier draws the surrounding air into the machine through the fan, filters out some particles and other pollutants in the air through the filter, and then discharges the filtered air. A small cycle of "dirty air" to "clean air" is formed to achieve air purification.
In the closed state of the air purifier, the carbon dioxide generated by the human body's breathing cannot be discharged in the closed environment of the closed door and window. It can only be "infinitely circulated" indoors. Over time, the indoor carbon dioxide content will increase, and chest discomfort, headache and other discomfort will occur.
The indoor environment is not exposed to fresh air, the air cannot be replaced, and formaldehyde cannot be discharged outside in time. In the case of low indoor ventilation, the formaldehyde content will increase the intensity of the emission. The measured data shows that under certain conditions, the concentration of formaldehyde in the air in the small living room can be above the standard allowable level, and the release period is relatively long. The research of Yokohama National University in Japan shows that the release period of indoor formaldehyde is 3-15 years.
In the process of use, the small purification area and slow wind speed are also problems that people gradually find. Under a certain space in the room, the purifying area of the air purifier can only reach 60 square meters, and the purification frequency is as low as 6h/time, which determines that the basic demand for breathing cannot be met. Unless you choose to place multiple air purifiers in your home, you will not be able to achieve full house purification.
In summary, it is not a complete negation of the purification effect of the air purifier, the air purifier also has the ability to purify, but in principle brings some limitations. This is why more and more people choose new fan systems.
New fan
The working principle of the fresh air system is that the outdoor air is piped to the inside of the machine, and then converted into fresh air into the room through multiple filtration inside the machine, and then the indoor dirty air is discharged outside the room through the micro-air pressure inside and outside. If the function of the air purifier is to purify the indoor air, then the fresh air system has the function of purifying at the same time, and also has the function of ventilation and ventilation.
The working principle of the fresh air system determines that it is not a range of purification, but space, that is, the whole house is cleaned, and the door and window are not opened in time, and the effect of “passing the wind” can be achieved. Compared to the air purifier's 6h/time, the fresh air system takes only 2 hours to keep the indoor air in the standard air range. The purification area depends on the amount of air volume, and the large air volume is also one of the advantages of the fresh air system. High-quality filter screen is used for efficient air filtration, and the purification efficiency is ensured without considering the trouble of frequently changing the filter screen.
