The Spring Festival is near, and many people want to move into a new home years ago. Some posts that “clean up†air pollution in new homes have also become hot posts on the Internet. Some disinfection methods, adsorption methods and even allegedly reduce ventilation time. Are these statements really effective in eliminating indoor air pollution caused by renovations? Are some of the formaldehyde-removing products on the market credible? Experts say that many methods on the Internet are “self-consolationâ€, to reduce indoor harmful gases, science Ventilation is most effective. Use formaldehyde removal products Expert evaluation: careful selection of fish and dragons Decoration deodorant, in addition to formaldehyde products... This kind of products for pollution control and pollution in the market can be seen everywhere, and many consumers will also question its effects. For this problem, experts said that for indoor air purification products, the National Indoor Environment and Indoor Environmental Product Quality Supervision and Inspection Center has launched a special industry standard - "Measurement Method for Purification Effect of Indoor Air Purification Products". Products tested by this standard are generally effective and can reduce pollution. Products that meet this standard are generally marked on the product description or on the packaging, and consumers can check it when purchasing. For some products popular in the market, Song Guangsheng made some explanations: activated carbon, bamboo charcoal and other products have the effect of passive adsorption of formaldehyde, and can effectively absorb harmful substances in the air such as formaldehyde in confined spaces such as cabinets, drawers and wardrobes. In comparison, the larger the dose, the more obvious the effect; some formaldehyde scavengers can be used in the decoration process. Experts reminded that some products used in the "spraying" after the renovation, we must especially choose carefully. "Basically can not solve the problem." Song Guangsheng said that some products have oxidizing components, after the decoration, it will react with some materials, such as causing metal jewelry to rust. Some products have an irritating taste and may be detrimental to human health. Other products completely rely on the smell to cover the decoration odor, so that the owners mistakenly believe that they can absorb the odor and play a blinding role. Experts said that if the house is heavily polluted, it is recommended that professional companies with indoor environmental pollution control qualification certificates be used to manage the products. Deodorizing with pineapple Expert evaluation: cover instead of absorption Many posts said that plants can be used, such as "can also put a few coarse fiber pineapples indoors to speed up the absorption of odor". However, Song Guangsheng pointed out that pineapple fiber is large and can breathe, but mainly uses its odor to cover the odor instead of absorbing the odor, and there is not much effect. However, some plants with large surface and large pores have strong photosynthesis, such as green radish and spider plant. They are suitable for use in newly renovated rooms. They do have the effect of purifying indoor air, regulating air humidity, and beautifying the living environment. effect. Consumers can consider buying some of these plants. Long window ventilation Expert evaluation: scientific ventilation effect is good The renovated living room should be ventilated and scented as much as possible. It takes at least five to ten days to complete the air purification work. This is everyone's consensus. Most people think that all the windows of the room will be opened before the decoration is completed. The longer the time, the more the decoration pollution can be eliminated. But experts say this is also a misunderstanding. In general, harmful substances such as formaldehyde release at the fastest rate at 15-20 degrees Celsius. The winter weather is very cold. If the air is ventilated for a long time, the indoor temperature is naturally low, and the harmful substances remain in the decoration materials, which has no effect. Song Guangsheng suggested that consumers can close the window first and warm the house to 20-25 degrees Celsius. After 1-2 days, open the window for 1-2 hours. Repeatedly, this method is most effective in eliminating indoor pollution. In the winter, ventilation is generally most effective between 10 am and 3 pm. Indoor water release in addition to formaldehyde Expert evaluation: still water has no effect at all For the removal of formaldehyde, there is also a saying that "there is more water in the room" because "formaldehyde dissolves in water". However, experts say that flowing water may dissolve formaldehyde, and still water is basically ineffective, so it is unreasonable to put a few more pots of water in the room to eliminate formaldehyde. Is it effective to use a variety of humidifiers? Song Guangsheng pointed out that the "ultrasonic" ordinary humidifier can only evaporate water and increase the humidity of the air. It is not the same as putting a few wet towels next to the radiator. Some humidifiers with fans, because they can circulate indoor air, produce convection, can absorb some of the formaldehyde and adsorbables in the air, which has a certain effect. Some air purifiers can effectively solve the physical, chemical and biological pollution of indoor air through the method of cyclic exchange, and have a certain adsorption effect on the formaldehyde content in the air. In the later life, consumers can consider it.
