Preparing for dealing with fog and haze in rainy days?! Although the weather is good these two days, the outdoor air environment has not been optimistic for a long time, so more and more people are closing their doors to consider creating a "small environment". Is it possible to keep indoor air clean through some means and measures?
Recently, air purification equipment has been selling very well. Some foreign brands are said to be hard to find. Some even want to reform the indoor ventilation system to prevent PM2.5 pollutants from intruding. As far as air cleanliness is concerned, there are only outdoor air standards and standards of special industries such as medicine, but no indoor air quality standards. For consumers, this means that there is no national "hard" standard to judge whether air purification equipment is effective. Industry insiders also believe that the quality of air purification equipment on the market is uneven, some air purification equipment in the laboratory measured data and household data are different.
According to the traditional idea, the best way is to keep the air flow and open the bedroom doors and windows for natural ventilation. But now, because of the occasional pollution alarm in the outdoor air, many residents have to be accustomed to closing doors and windows. How to create a fresh indoor environment? As a professional way of air purification, mechanical ventilation has attracted the attention of many citizens.
Mechanical ventilation, in short, is the conversion of polluted air into clean air by installing some blocking devices and purification facilities. At present, this extraordinary air purification air conditioning equipment is generally used in food, cosmetics, medicine and other industries which have higher requirements for air cleaning.
This kind of air conditioning has obvious effect on air purification, so far, its application in the industrial field is very mature, but due to low resistance, high power, and high operating noise, the use of high cost is an objective reason, it can not be popularized on the level of civil use. If it has to be used in civil buildings, the installation conditions of air conditioning rooms can be set up independently in a small number of newly built high-end residential buildings.
The vast majority of air purification equipment sold on the market are internal circulation devices. Can such air purification equipment completely remove PM2.5 and produce the effect of clean air? Experts say that the actual use is related to the specific living environment and area of each household and other factors. Data are tested in the laboratory for better air purification equipment, which can be discounted in the use of households, and it is difficult to monitor.
The use of air purification equipment on the market is similar to that of many water purifiers. At first, the water quality is up to the standard, but with the improper maintenance in the future, it may lead to secondary pollution. Therefore, this kind of machine will produce certain effect in local use, but it is not suitable for long-term, day and night use. The quality of air purification equipment on the market is uneven. Due to the lack of monitoring standards, some measurement data are not good enough, and purification equipment is not selling well. Some domestic enterprises without qualifications or lower qualifications imitate products produced by purification equipment produced by foreign brands. Once improperly used, it will become a new kind of air pollution and have a negative impact. However, the good news is that domestic research institutions have gone through a technological breakthrough in the development of indoor fresh air and civil air purification air conditioning. Perhaps in the near future, this new product that meets the expectations of ordinary citizens will soon be on the market.
