Part1: the bedroom pollution in winter pays great attention to ventilation and cleaning

Many harmful gases, such as formaldehyde, have the characteristics of increasing air temperature and release quantity. Therefore, many people believe that due to the low temperature in winter, the harmful gases become slow to volatilize and the pollution becomes less. That is not the case, however, and indoor air quality may be worse in winter than in other seasons. How to respond? Here the air purifier manufacturer of sharp platinum is introduced to everybody is the most economical and effective method, that is to open a window properly ventilated with the bedroom cleanness.

I. indoor air pollution source in winter

1. Air pollutants increase in heating season

In winter, the temperature is low, but the indoor temperature is not necessarily low. In order to keep warm, people often use various equipment to build a warm environment in their homes. Some people open air conditioning because of summer, winter is warm, appear winter indoor temperature is higher than the case of summer. And formaldehyde, TVOC and other substances in 20 degrees, the volatile speed will increase sharply. In addition, in some underdeveloped areas, people may resort to backward heating methods such as charcoal or coal ball, which is more likely to cause indoor carbon monoxide, carbon dioxide and particulate matter higher than other seasons.

2. Ventilation reduces pollution and does not spread easily

In order to maintain the temperature inside the bedroom, the window of many family often opens not quite a few times in winter. As a result, indoor and outdoor air can not be convective, indoor air pollution can not spread out.

Sharp platinum air purifier manufacturer reminds: look at a problem to need comprehensive, do not know only one, do not know two, although temperature is low really can reduce pollution release, but there are many other factors that can cause air pollution in winter. The indoor air situation in winter is not optimistic. On the other hand, people spend much less time outdoors, and human body resistance is lower in winter due to the lack of exercise and other reasons. Therefore, indoor air pollution in winter causes more harm to human body.

Second, the highest cost performance window ventilation pollution

Generally speaking, outdoor air quality is often better than indoor air. If the window is often opened for ventilation, the dirty air can float away, and viruses and germs are difficult to breed. Therefore, unless the outdoor air quality is really bad weather, other time, window ventilation is often more effective to reduce the indoor air pollution index. There are some points for opening Windows and ventilation.

1. Windowing and ventilation skills in winter

Choose the best time to open Windows

According to the test, there are two pollution peaks and two relatively clean lows in the urban atmospheric environment day and night. The two pollution peaks are usually around sunrise and evening, and the two relatively clean periods are around 10 am and 3 PM. In relatively clean times, the window can be opened appropriately to maintain the fresh indoor air.

Window opening times and time control

Window opening is not more, better, because winter heating, frequent window opening will waste energy, affecting the comfort of indoor temperature, so we need to master the number of window opening and each time window opening time. Usually, when the room is small, the wind outside and the house is see-through, the window opening time can be shorter. The window opening time can be longer if the room is large and there is no convection ventilation, no wind outside or small temperature difference inside or outside.

Use window opening time

The Windows can be screened

For Beijing, Shanghai and other cities with severe air pollution, the outdoor air quality itself is poor, if you want to open Windows for ventilation, it is best to put filters on the Windows. It is to give a layer of special filter to the window, decide the pore size of filter net according to outdoor environment, block most pollutants outside.

2. Matters needing attention for ventilation of newly decorated houses in winter

Due to the inside of the new decorating houses and furniture such as formaldehyde chemical pollution needs under the condition of more than 20 ℃ to volatilize effectively, so in the case of indoor and outdoor temperature is low in winter, ventilation for a long time will not be able to rise to eliminate the role of furniture and decoration pollution, purify air, it will make no dry after decorating metope paint is easy to freeze, causing metope color change after beginning of spring, metamorphism and pulverization wooden paint. Therefore, it is best to ventilate on warm afternoons in winter, and the ventilation time should not be too long.

Correct cleaning to reduce indoor dust pollution

The vast majority of respiratory tract patients are caused by indoor dust, especially our most common cleaning, shaking clothes, patting dust on the body, wiping the table with dry towel, etc., which are very easy to raise indoor dust again and cause indoor air pollution. Therefore, there are two points that need special attention when doing indoor cleaning in winter.

1. Keep the radiator clean

The radiator should be cleaned frequently to protect the cleaning, because if there is dust on the radiator, it is easy to evaporate in the air with the rising temperature, resulting in increased dust content in the indoor air, which is harmful to human health.

2. Use proper methods to clean

When indoor clean, want to use proper method to undertake. Like vacuuming the floor as much as possible; Wipe the table and the floor after the cloth and mop are wet. When patting your clothes or quilts, go outside and pat to avoid raising the dust in the room again.

Part2: suitable temperature and humidity to reduce indoor air pollution

As mentioned above, one of the causes of excessive indoor air pollution in winter is due to the reduction of window ventilation and the other is due to the higher heating temperature. The solution of any problem needs right next medicine, the main point that reduces indoor air pollution in winter is to want to control indoor temperature and humidity.

1. Effects of temperature and humidity on formaldehyde emission

1. Temperature influence

The higher the indoor air temperature, the faster the release of formaldehyde. Formaldehyde volatilizes point of 19 ℃ and room temperature every 1 ℃, formaldehyde concentration will rise 0.4 times; If average in more than 20 ℃, the concentration of more than three times the normal release.

2. Influence of humidity

Formaldehyde is a colorless gas with strong pungent smell, which is soluble in water. Therefore, if the relative humidity of indoor air is relatively high, formaldehyde is easily dissolved in water mist and stays indoors.

Warning: formaldehyde is the most harmful pollutant to human health in indoor air, and the change of temperature and humidity has great influence on the release quantity of formaldehyde. Therefore, if we want to reduce the content of formaldehyde in indoor air, we can control the indoor temperature and humidity in addition to taking ventilation measures.

Indoor temperature should not be too high in winter

Indoor temperature should not be too low in winter, too low makes people feel cold and uncomfortable, but it should not be too high. If it is too high, it will increase energy consumption on the one hand, and on the other hand, it will also easily cause the release of indoor pollutants such as formaldehyde. The most suitable temperature for winter is between 16 and 22 degrees, and it is better not to exceed 22 degrees. It is recommended to keep it at 19 degrees (i.e., formaldehyde volatile point).

3. Indoor humidity should be added in winter

In winter, many people wake up feeling dry in the throat and cough easily, which means the humidity in the room is low. Although say humidity is too high, easy cause indoor air pollutant dissolves in water vapor, adverse to human health. However, if the humidity is too low and the room is too dry, it will aggravate the dust phenomenon and make people easy to get on fire. Accordingly, winter needs to undertake to indoor add wet appropriately. According to the test, indoor humidity is best kept between 30% and 60% in winter. Some of the following humidification methods can be adopted.

1. General indoor humidification methods

Indoor humidity is low in winter, but if it is not particularly low, there is no need to use a special humidifier, but can be used in general ways to humidify. For example, burn a pot of water on the stove, open the cover and let the water evaporate. Hang some damp clothes, towels, etc indoors. Spray water on the ground and place a basin of water in the room. And put some humidifying plants indoors.

2. Use a humidifier for humidification

Humidifiers can achieve rapid changes in indoor humidity, but there are several points to note when using them in winter. First, must clean regularly, otherwise the mold and other microorganisms in the humidifier into the air along with the fog, and then into the human respiratory tract, easy to get humidifier pneumonia; Secondly, the higher the air humidity, the better. In winter, the human body feels more comfortable about 50% of the humidity.

Part3: quickly and effectively purify the air purifier in winter

Indoor pollution is serious in winter, but outdoor air quality is not necessarily good. The smog has been getting worse not only in Beijing but also in Shanghai recently, with the meteorological department issuing notices to people to reduce outdoor activities. With the dilemma of staying indoors or outdoors, it may seem like a good solution to choose a quality air purifier.

I. working principle of air purifier selection

Air purifier is working, first start the fan and the air inlet into the air purifier, generally after the outermost layer of dust filter filter first hair, large particles of dust, and then through the filter, hepa filter, activated carbon filter, or in addition to formaldehyde filter (varies according to the actual use of mesh type), after the last layer of light accelerant mesh catalytic decomposition reaction (electrostatic adsorption type air purifier, this layer is the electrostatic adsorption layer), after purification of air through the air duct by vent discharge.

Ii. Purification technology of sharp platinum air purifier

At present, there are many air purifiers on the market, and the air purifier purification technology is different. At present, the purification technology of air purifier can be divided into three categories: filter screen, electrostatic adsorption and ionization filter. According to the different materials and functions, the filter net can be divided into dust collection filter, deformaldehyde filter, activated carbon filter and HEPA filter. Electrostatic precipitation technology is used to filter pollutants in the air based on the principle of high-voltage electrostatic adsorption, but the ozone release has a slightly higher disadvantage. Ionisation is also a common method currently used.

Use of air purifier in winter

When using the purifier in winter, always check the internal cleaning degree and filter state of the air purifier, and replace the filter timely to avoid secondary pollution. In addition, air purifiers are recommended for frequent continuous use and are not recommended for intermittent use.

Part4: live more comfortable indoor air pollution detection governance

The above mentioned windowing ventilation, attention to cleaning, temperature and humidity control and the use of air purifiers are effective ways to control indoor air pollution in winter. But one of the problems with all of these methods is that you can't make sure that the air in your room is clear, clean, or even above standard. So if you want to be more comfortable, have a test of your home's air quality.

One, bedroom air detects government

1. The decoration company shall cooperate with the environmental monitoring of newly decorated houses

This year September 1 begins to implement "household industry management standard" as the first industry standard, to bedroom environmental protection monitoring also made a regulation. That is, when the owner needs, the decoration company shall cooperate with the customer to carry out indoor environment monitoring services including formaldehyde, benzene, ammonia, toluene, xylene, TVOC, etc. The test results shall meet the requirements of GB50325(" code for indoor environmental pollution control of civil construction projects "), and the owner shall be present to supervise the acceptance and sign for confirmation.

Small make up remind: before if owner is not at ease, indoor air environment, after inviting environmental protection to examine an organization to undertake examining proves unqualified, very common circumstance is decorate a company not to admit an account. New regulation this one provision should be very advantageous to owner, although detect cost is general by the party that proposes to need to examine, it is owner expenditure normally. But if the test results do not meet the standards, then decoration companies need to be responsible for the problem, decontamination treatment.

2. Professional company testing management

With the emphasis on indoor pollution, many pollution detection companies have emerged in the market. If the owner wants to make an accurate measurement of indoor formaldehyde content, he/she should choose an authoritative testing agency with qualification (CMA certification, etc.).

Detect commonly management collects fees circumstance to be collected according to exceed bid circumstance and actual area, for example the charge circumstance of some orgnaization is if harmful material composition exceeds national standard 1 times, it is to be collected according to 10 yuan/even charge; If the amount exceeds 2 times, the charge shall be 15 yuan per square meter; If it is more than 4 times, it will be charged at 20 yuan per square meter. To make test results more accurate, close doors and Windows for 1 hour before test. Professional testing and governance can greatly shorten the governance time of traditional methods, and can quantify the results, so that owners can be more confident.

Two, indoor air purifies management error

1. Judging pollution by smell is not reliable

Judging pollution beam by smell is not reliable, no smell is not equal to no pollution, and the human body's sense of smell will be reduced in winter. Accordingly, cannot think the bedroom does not have peculiar smell inside, can rest assured live. In addition, some folk methods, such as using tea leaves, grapefruit skins, onion slices, pineapple chunks, etc., or using white vinegar to fumigate the whole room, are also useless. These methods generally only cover the smell, but do not remove the pollutants.

2. Avoid secondary pollution of cleaning products

At present, there are a lot of products that remove pollutants such as formaldehyde in the market. Some experts of indoor air monitoring have pointed out that scavengers such as formaldehyde can only temporarily close the source of pollution and prevent the volatilization of pollutants in a short period of time. Cannot blindly believe the exaggerated propaganda of businessman, general to decompose formaldehyde to wait for "dispel agent" and "close agent" in chemical way, want careful use, lest cause second pollution.
