Now that it has entered a period of high incidence of smog, people began to experience the pain of breathing. Many people think that the indoor air in the haze is much better than the outdoor. As long as the doors and windows are closed and the house is at home, it can prevent smog. Is that really the case?

1.Is the indoor air better than the outdoor in the fog?

Engineers from the China Academy of Building Research have found through many field measurements that the concentration of PM2.5 in the room is not necessarily lower than that of the outside, due to factors such as smoking and cooking. The measurement found that in the case of no window opening, no smoking or cooking, the concentration of indoor PM2.5 is generally about 30% to 40% lower than the outdoor concentration. For example, if the outdoor is about 500, the indoor temperature is usually about 300-350. Another set of test data shows that some household indoor PM2.5 concentration values ​​are higher than outdoor. One of the households found that the outdoor PM2.5 concentration was 230 μg/m3 and the indoors reached 474 μg/m3 when the door was closed for several days. Therefore, it cannot be said simply that the indoor air in the haze is necessarily better than the outdoor.

2.The source of indoor air pollution

Indoor PM2.5 is affected by many factors. Previously, they also monitored some public places, and the PM2.5 concentration inside was even higher than that of the outdoor. This was caused by many factors. Hou Li’an, an academician of the Chinese Academy of Engineering, said that the source of indoor PM2.5 is mainly from outdoor pollution sources and indoor pollution sources.

Source 1: Outdoor

When the fog is severe, the window opening is not properly ventilated, and the indoor PM2.5 concentration will rise rapidly. At the same time, in the case of closing the doors and windows, it does not mean that the air flow is isolated. The tiny PM2.5 particles can still run into the house. At the same time, people will carry a variety of fine particles and microorganisms when they go out to their homes.

Source 2: Indoor

In fact, daily activities such as gas burning, kitchen fume, indoor smoking, air conditioning heating, furniture decoration, etc. will bring PM2.5 to the interior. Because the indoor space is small, the probability of producing PM2.5 in a closed room is more obvious than that in the outdoor, so the home is not necessarily absolutely safe at home.

3.How to purify indoor air

In the face of the ‘ten crouching’ environment, how should we properly clean indoor air, effectively suppress indoor PM2.5 pollution, and create a healthy and healthy indoor environment.

1)Properly open the window ventilation

If the fog does not open the window, it can reduce the intrusion of PM2.5. However, long-term indoor ventilation will cause the concentration of carbon dioxide and other exhaust gases to slowly exceed the standard, and the content of microorganisms and bacteria will increase, even more than outdoor air. Not enough, people will feel poor breathing. Therefore, smog days also need to open windows for a short time. The staff of the provincial environmental monitoring station suggested that when the outdoor air pollution is not very serious, avoid the traffic peaks and winds caused by morning and evening. When dust is raised, under the static wind conditions, you can open the window twice a day for 20-40 minutes. If you encounter continuous pollution, you can hang a wet towel near the screen window when ventilation, which can filter and absorb. effect.

2) Raising green plants

Some experts suggest that when outdoor air pollution is serious, you can plant more green plants with relatively strong adsorption capacity on balconies, terraces, indoors, and try to select large leaf plants. Because of the large leaf area and many pores, it can not only adsorb PM2. 5, can also increase the oxygen content of the air. Such as green radish, evergreen, tiger skin, ivy and so on. Since the surface of the plant contains a layer of adsorptive mucus, this mucus has a strong adsorption function for tiny particles. At the same time, plants can also adsorb a small amount of PM2.5 during photosynthesis. Therefore, using natural means such as green plants to help slow indoor PM2.5 pollution is both effective and trouble-free, and can add a green color to the home.

3)Less smoking

Cigarettes, cigars and pipes produce a lot of fine particles in the PM2.5 category when incompletely burned. Tobacco smoke contains more than 7,000 compounds, including 69 carcinogens and 172 harmful substances, which can seriously harm the smoker itself. And the physical health of the inhaled ‘secondhand smoke’ audience is even worse in the ashes. Therefore, smokers should smoke as little as possible, whether they are going out or staying indoors.

4)Choose the air purifier

A good air purifier has a good adsorption effect on PM2.5 and can play a certain purification role. The core of the air purifier is the filter. If you want to filter PM2.5 particles, the best internationally recognized HEPA high-efficiency filtration technology can effectively suppress allergens in the air, such as dust, pollen, germs, second-hand smoke, dust. Such as small particles, the purification rate for particles of 0.3 microns is 99.97%. If it is used to filter cigarettes, the effect of filtration can be almost 100%, because the size of the particles in the cigarette is between 0.5 and 2 microns, and the membrane cannot pass through the HEPA filter.

5)Light diet, soot filtration and discharge

Cooking fumes also have a small contribution to PM2.5. Cooking, frying, frying, roasting, etc. will cause indoor PM2.5 to soar, so when cooking, replace with cold, steamed, boiled, marinated, etc. It is possible to control the oil temperature not to exceed 200 °C.

When selecting a range hood, the inner row hood should be considered more, because the hood type hood only discharges the exhaust gas directly to the outside after a simple soot separation, which is very harmful to the collective environment. The inner-row hood also uses a filter to absorb harmful gases after the soot is separated, and then discharges the purified gas. At the same time, the range hood should be opened early and closed, and the kitchen window should be ventilated.

6)Do indoor cleaning and personal hygiene

Wipe the tables and chairs with water in the house and mop the floor, because the humid air helps to reduce dust and fine particles floating in the air. In addition, the use of a humidifier, the placement of towels on the heater, the cleaning of sheets, pillows, etc. with a wet towel are all desirable methods of absorbing fine dust. In addition, use air fresheners or cleaning products as little as possible, including aldehydes, benzenes and other pollutants.

After going out to the room, you should wash your face, rinse your mouth, clean your nose, and remove the contaminated residue attached to your body. This will minimize the adverse effects of smog on health. It is best to use warm water when washing your face, which is good for washing off the particles on your face. When cleaning the nasal cavity, you can use a clean cotton swab to wash the water repeatedly, or repeatedly use the nose to gently absorb water and quickly rub your nose, while avoiding coughing. In addition to facial cleansing, the exposed parts of the body are also cleaned.

7)Replace the closed door and window

Under the influence of outdoor bad weather, tiny particles will enter the room through poorly sealed doors and windows, which is an important way to generate indoor PM2.5. The use of more airtight doors and windows is conducive to the reduction of indoor pollution values. Therefore, when replacing the doors and windows, it is necessary to choose a good airtightness, and the sound insulation and dust can be obtained in one fell swoop. The sliding window is more airtight than the casement window. When replacing, try to choose the casement window.

With the increase of smog and the awareness of residents’ health and environmental protection, air purifiers have become more and more popular in residential homes, especially in large cities with poor air quality. Air purifiers have become almost essential household appliances. But how much harmful substance can the air purifier used in the house get rid of? Is there any worry about the air purifier?


Due to the uneven air purifiers on the market, the smog weather counterfeit goods quickly enter the market to attract consumers’ attention. Counterfeit goods due to rough workmanship internal structural components are not up to standard, their purification ability is very poor, and may even bring secondary pollution to the indoor environment. Some purifiers have advertised exaggerated purification effects, claiming that formaldehyde, PM2.5, PM10, and xylene are all eliminated, and some purifiers generate ozone when they run, which makes consumers hard to prevent. Therefore, the unified home small series reminds consumers to pay attention to quality and quality when purchasing air purifiers, and choose suitable purifiers and other furniture appliances.

Filter maintenance

Air purifiers can improve the environment in which we live and make the environment better. However, it is worth noting that if the air purifier is used improperly, especially if it is not maintained for a long time, it will cause harm. It is recommended that it be used during the process. Regular maintenance of the air purifier.

When using the air purifier first, pay attention to closing the doors and windows. The air purifier is designed to circulate and purify the air in a relatively confined space, and the door and window are closed to ensure the filtering effect. However, according to Yitong Home Xiaobian, it is necessary to use the air purifier for a long time or to open the window for ventilation when the outdoor air is good.

Secondly, it is necessary to develop the habit of regularly checking the air purifier filter to clean and replace it according to the pollution situation. The core components of the home air purifier – HEPA filter and activated carbon filter, usually need to be replaced after 3-6 months of use, otherwise the purification effect is greatly reduced or even used is useless. Once the filter fails, it should be replaced in time, otherwise it will not be conducive to purification and damage to the machine. According to the description of different brands and different types of products, the filter can be replaced regularly according to the requirements to ensure the use of the air purifier. For the filter replacement of the air purifier, refer to the manufacturer’s manual. If there is a product for the filter replacement reminder function, the reset operation is required after the filter is replaced.

If the air purifier is used improperly, there may be no purification effect. Some air purifiers may also generate harmful gases such as ozone. If used incorrectly, cleaning may not cause secondary pollution of indoor air. Therefore, the unified home furnishing consultant reminds consumers to know the usage methods and precautions when purchasing the air purifier, and pay attention to the correct cleaning and maintenance during the use to achieve good air cleaning effect.

Which kind of pollutants effecting the air quality?

                                                                      Which kind of pollutants effecting the air quality?

Air means the gas surrounding the earth, which supported human being and other living organisms. Air quality represents the degree of air pollution, which was measured off by the consistence of pollutant in the air.

Olansi is a professional manufacturer which engage in design, production and sale household Air Purifiers , automobile air purifiers and commercial air purifiers. Olansi believes following pollutants effecting the air quality:

Carbon Monoxide: Carbon Monoxide is the product of the imperfect combustion of coal, oil and other carbonaceous matters, which is a colorless, odorless, non-irritating and poisonous gas. Carbon Monoxide is practically insoluble in water, difficult to have chemical reaction with other matters in the air, so it could stay in the atmosphere for more than 2~3 years. If the concentration big enough, it could harm and even kill over a long period of time.


Inhalable Particulates: Means particles suspended in a gas, wholes diameter is less than 10 micron. Concentration of Particulates is denoted by the mg. numerical value of Inhalable particulates in each stere. The smaller particles could be breathed the deeper. Total suspended particulates is a blanket term for suspended solid and liquid state particulates, diameter of these particulates is about 0.1~100 micron. Some particulates such as soot is visible because it’s dark enough or with larger diameter, while some particulates are very small, which can be seen only under an electron microscope. Usually we call the particulates PM 10, inhalable particulates or floating dust if the diameter is smaller than 10 micron. PM10 could stay in air over a long period of time, which effect healthy and visibility in atmosphere a lot.

So we need a Air purifier to improve the Air quality. An air purifier can remove most or all the impurities present in the indoor air. It is necessary to know about different type’s filters before choosing one.

  • High-Efficiency Particulate Air (HEPA) filter trap air borne particles, when the air is forced through filters. They remove air pollutants of 0.03 microns or greater in size. They are efficient in removing solid dust particles, pollen, and mold spores. However, they are unable to remove bad odor and chemical fumes.
  • Ionic air filter provide a negative charge to the particulate matter in the air, which is attracted to positively charged pollutants in the air. A combination of these particles is heavy and hence they settle down. Some of them may also contain two metal plates with positive and negative charge that attract oppositely charged particles present in the air.
  • UV air filter sterilize the indoor air by making it pass through UV lamps using forced air. They are effective against microbes such as bacteria and viruses. They can be chosen to provide a cleaner place for a sick family member in your home.
  • Carbon activated filter incorporate adsorption technology. When the particles and odors pass through the filter, they are bonded to the activated carbon. They are suitable for adsorbing gases, odors, chemicals, and fumes.

Choose the air purifiers combine with the filters above would be keep your indoor air clean and healthy. It could prevent your family from falling sick.
