Is it the sorrow of society? Need an air purifier to maintain breathing air?

　　A few days ago, I saw a comment from a netizen: "I don't know if the society is progressing or regressing. Even breathing fresh air requires an air purifier to maintain it." When I first heard it, I felt that this comment was a bit exaggerated, but after thinking about it , found this to be the case.

　　Time can always change many things. It can make Xiaoyaer break through the thick layer of soil and see the heaven and earth under the sun; it can make high-rise buildings rise from the ground to create a prosperous city; it can make the long-sleeping oriental dragon Wake up, take off in the heaven and earth. Society has indeed become prosperous, but people's living standards have regressed. There may not be as many high-rise buildings in the past, but they have the most ordinary fresh air.

　　In its current form, it will be unknown whether the fresh air will return. So let’s face it, we still need a proper air purifier, and why?

　　There are many types of air pollutants indoors, the most obvious ones are smog, formaldehyde, odor, bacteria, etc. These pollutions have significant harm to the human body. The basic principle of the air purifier is to continuously circulate the indoor air, and use some means to adsorb the pollutants in the air on the filter screen, and then discharge the filtered air, and cycle back and forth, so as to resist the pollution source and purify the room. purpose of air.

　　Indoor Air Purifier

　　The indoor air has been purified, so how about the outdoor air? Some people even think that staying indoors 80% of the time is a wrong calculation. They feel that the time spent indoors may be a long time, but there is definitely no 80% share. Here, we make a ratio: "The vast majority of people need to go to work, and they basically stay indoors. At this time, work time accounts for about one-third of the day. Sleeping is needed every day, and this should also account for three. Molecules one, where does the other 15% come from? Yes, the probability of staying indoors from get off work to bedtime will be at least occupied by this 15%.” This example also proves the importance of indoor air.

　　Life is always like this. I have experienced both good and bad. Now that the material living standard has improved, maybe everyone still misses the old days. Life is often so contradictory. If something is lost, it may be hard to find it again. Fresh air may have been an ordinary life element in the past, but now it has become a "luxury accessory". But in the era when money is self-will, everyone may think that there is an air purifier anyway? I feel that I can sit back and relax, but in the long run, what will life be like, who can say clearly?
