HC Water Purification Network In recent years, many Xi'an citizens have found such a rule that the air will deteriorate when the heating season is reached, and PM2.5 will exceed the standard. At the end of the heating season, the air quality in Xi'an has greatly improved due to the arrival of monsoon weather from the beginning of April to the first half of October. This year has also continued this pattern, especially since May, except for the rainy days, almost every day is a blue sky.
So, does owning the blue sky really mean having good quality air quality? This is not the case. The outdoor air is not equal to the high indoor air quality. With the arrival of summer, everyone should check the air quality at home.
The air conditioner is cleaned or replaced after a period of use.
It is almost time to use the peak season of air conditioning in the summer. Many consumers only know that the air conditioner is turned on when they are hot, but they do not know how to clean the air conditioner. If the air conditioner does not wash all the year round, it will become the biggest source of indoor air pollution. No matter how blue the sky is outside the window, the air in the house will exceed the standard every day.
The person in charge of Gree air-conditioning said that after using the air conditioner for a period of time, due to the electrostatic action and repeated air circulation, a large amount of dust, dirt and harmful bacteria will accumulate on the surface of the filter screen and the evaporator. Some cabinet air conditioners are hung outdoors all the year round, and the wind blows the sun and rain, causing a large amount of garbage and pests inside. When using air conditioners, it emits an unpleasant smell and endangers human health. After the air conditioner accumulates dust and other things, it will also cause cooling and heating effects to decrease, increase power consumption and noise, and even cause damage to the compressor, increase the failure rate, and reduce the service life of the air conditioner.
In addition, since the door and window are closed and the air does not circulate when the air conditioner is turned on, not only odor is generated, but also bacteria, viruses, mites, etc., which pollute the indoor air and spread diseases, which seriously affect human health.
The person in charge of Haier air-conditioning said that the temperature is not cold or hot, it is the best time to clean the air conditioner. When cleaning the air conditioner, be sure to ask the staff of the professional service company to clean it, so as to ensure the quality of the cleaning. Of course, you can also clean it yourself, but be sure to understand the internal structure of the air conditioner, otherwise don't try it easily.
In addition to air conditioning, many homes now have air purifiers. Like air conditioners, the filters of air purifiers are filtered through a winter and are also full of dust. Professionals said that the filter of empty equipment should be replaced at least two years, and areas with serious air pollution should even be changed every year. It should be emphasized that the empty net filter can only be replaced and cannot be cleaned.
Be wary of excessive ozone
Partial empty net hazard indoor air environment
Strong sunshine in summer can easily lead to excessive ozone in the air, thus damaging human health. Not long ago, Beijing-Tianjin-Hebei and Shanghai were surrounded by high-temperature sunshine, resulting in a large area of ​​ozone exceeding the standard. For consumers, the most direct way to avoid ozone hazards is to go out at noon and close indoor doors and windows. However, there is still a very serious problem, some of the purification equipment will also produce ozone, which will harm the indoor air environment.
Empty equipment that produces ozone is mainly concentrated on some plasma air purifiers. Experts said: "Ozone has a strong oxidizing power, which can disintegrate bacteria from the inside, or directly interact with bacteria and viruses to kill bacteria and viruses." But ozone itself is also a pollutant. It can damage the respiratory tract of the human body, irritate the eyes, and cause dark spots on the skin. Experts say that when the ozone concentration reaches 200 micrograms per cubic meter, it can even damage the central nervous system of the human body, causing headaches, chest pain and decreased thinking ability. Therefore, try not to purchase air purification products that use ozone to remove PM2.5.
Nowadays, air conditioners and air-cleaning equipments on the market are loaded with sensors, which can intelligently monitor harmful substances in the air, and can communicate with mobile phones. Whether indoor air is up to standard or not, and harmful substances in the air can be viewed from mobile phones. Large particle pollutants like ozone can be seen directly from the mobile phone, so that it is easy to grasp the air quality information in time.
In addition, it should be noted that due to the high temperature in summer, furniture, curtains, etc. in the home will be volatile, formaldehyde and other harmful substances, so consumers can not completely close the empty equipment, as long as the purchase and use of empty equipment Confirm that ozone will not be produced, and it should be opened frequently in summer.
