Many haze days promote the hot air purifier

Recently, smog weather in many places in our country has had a great impact on people's lives. After investigation, the major hospitals in Beijing recently accounted for almost one-third of the respiratory diseases, including children and the elderly. In the face of haze, we can only face it passively. How to minimize the impact of PM2.5 on the body has become the most concern for people nowadays. Traveling wearing masks and installing indoor air purifiers have become the most practical method nowadays.

How to choose a mask and air purifier naturally becomes our most concerned and practical topic now. The choice of mask is naturally the best choice for gauze masks with more than 12 layers, but the higher the filtering level, the greater the respiratory resistance will be. , Wearing for a long time will have an impact on the human body, so it is recommended to wear short-term travel.

The air purifier is not all models can effectively remove PM2.5 dust. Consumers need to carefully identify the types and models of air purifiers.

And for another appliance that needs to spend money, we think that it is just a small household appliance only. There may be more consumption than you think in this, according to the comparison between major electricity providers in the global home network, ordinary air Although the price of the purifier is low, the price of the PM2.5 dust can be filtered at least from RMB 700 to several thousand RMB. It has to be said that the air purifier has been rapidly heating up in the past in an industry that we do not care about. It has become one of the most popular home appliances recently.

The best and most efficient air purification method can now be divided into two types: air purifiers and air conditioners. The advantage of air conditioning is obvious. It can remove dust when heating/heating. The function of the air purifier is more specific, and the effect of removing dust particles is definitely better than that of air conditioners. However, the gap is not very clear. How to choose them also requires consumers to consider their own use requirements.

Air purification industry competition is inferior to Europe and the United States Currently in the home appliance industry in the air purification field layout companies have the United States, Gree, Haier, Hisense and TCL Group. One of the United States entered the air purifier industry as early as June 2003 and formally established the air purifier company in July 2005; Gree also entered and launched the air purifier earlier; Qingdao Haier launched the first time in the first half of 2012 to remove PM2. 5 air conditioners; Hisense Group's flagship product in the "Apple Pie A8" series launched at the end of 2012 has a PM2.5 removal rate of up to 99.9% after 1 hour of operation; TCL's small home appliances division under 2012 Half a year announced that it will enter the air purifier market with 2 Series 4 products.

The monitoring data from Zhongyikang indicated that from the data of 2010, 2011 and the first three quarters of 2012, the annual increase of air purifier retail sales was over 11% year-on-year, and the increase was increasing year by year, with a year-on-year growth rate of 11.4%. Increased to 14.7%. From the market share of each brand, foreign brands accounted for about three quarters of the market share, of which Philips and Panasonic's retail volume share was 33.4% and 28.5%, respectively, which ranked second; local brands Asia Pacific and Midea retail Volume share slipped to 18.5% and 3.9%, respectively.

Although the future of the air purifier industry is chaotic, the prospects for the future are bright. Zuo Yanxi, brand director of the Yikang Market Research Institute, said that there are many brands in the air purifier market in China, and there are a lot of chaos in the market. The main focus is on small and medium-sized enterprises, and there are fewer large-scale enterprises. Mainly concentrated in the Yangtze River Delta and the Pearl River Delta region. At present, the penetration rate of air purifiers in China is less than 0.1%, and there is huge room for improvement in the amount of inventory. With the release of PM2.5, people are paying more attention to the living environment and air quality, and there is a large market space for the air purifiers as the sunrise industry. It is estimated that by 2015, the indoor environmental protection industry including air purifiers will have an annual output value of 80 billion yuan.

The air purifier has a global market capacity of more than 13 million units, of which North America is the largest air purifier market, with annual sales of nearly 4 million units, European and Asian annual sales of air purifiers are also more than 3 million units, and China’s sales volume is 1 million units. about. During the “11th Five-Year Plan” period, sales of air purifiers will increase at a rate of 27% per year. It is expected that the air purifier industry in China will maintain a high growth rate of 30% from 2011 to 2015.

After the investigation of the global home network market, after several actual surveys of large and medium-sized stores, there are many brands of air purifiers. In addition to the above-mentioned brands such as Philips, Midea, and Asian Capital, there are still some brands that have never heard of it. Compared with the actual price, the price is actually relatively cheaper, but in fact, the gap between the specifications is only about 100 yuan, even some product prices surpass the brand products, and after talking with the store salesperson, regardless of price, almost every product can be guaranteed purification The effect of dust, but after actually viewing the product description is not like the salesman said.

Therefore, it is recommended that you do not blindly buy products when the direct salesman's "flicker", when the choice of products, it is best to ask for a look at the product's instructions and description, and issued a unified national invoice for the post-warranty replacement.

How to choose a variety of air purifier air purifier purification methods, not every kind can purify the PM2.5 brought about by the dust, the following to introduce you to the purification of air purifiers, I hope you choose the air purifier can Help.

1. Low-temperature asymmetric plasma.

2, chemical agents. The main products are air fresheners (car perfumes). Their products are inexpensive, but they can only cover up some odors. They also cause complex chemical reactions under the action of sunlight and become new pollution inside the car. They can't eliminate harmful gases at all.

3, chemical decomposition. The main working principle is the ionizer ozone generator. Its low price and more function than the freshener can increase the amount of negative ions in the air and reduce the solid dust in the air. It has a bactericidal effect but has little effect on the decomposition of formaldehyde and other harmful gases. The ozone generator produces large amounts of high-concentration ozone. While killing some virus bacteria, it may also kill human white blood cells, which may cause canceration. Negative ions easily absorb dust and adhere to the ceiling of the interior walls of the carriage, resulting in special interior compartments. A light-colored car will gradually turn grayish black.

4, adsorption, volatilization. It is a purifier using Chinese herbal medicine as a medium, which is inexpensive and has a certain antibacterial function. However, the Chinese herbal medicine does not substantially achieve the purifying effect in the solid state. The Chinese herbal medicine used in the purifier is only a trace amount, and after being saturated, it cannot only be sterilized but also becomes bacteria easily. The multiplication of the filter element and the replacement of the filter element involve difficulties in the treatment of harmlessness.

5, adsorption. Activated carbon filter can absorb certain bacteria and dust and harmful gases in a short time, low in price, able to filter certain bacteria and dust with adsorption function, but no selective adsorption, the adsorption rate of water is 45%, generally for one month After it can reach saturation, it needs to be replaced. Can not be recycled. Not only cannot be sterilized after reaching saturation, but also it is easy to become a bacterium. The replaced filter element also involves the difficulties of harmless treatment.

6, multi-layer filtration. Mainly for the compound purifier, filtering effect is good, can significantly reduce the solid dust in the air, but the price is higher, and the filter device requires replacement after a period of time, can not be regenerated, basically no effect on harmful gases. Consumables, high cost of use. Replacement of the filter involves difficulties in the treatment of harmless.

7, catalysis, decomposition. Photocatalyst purifiers are mainly used to decompose some harmful gases. The price is relatively low, but photocatalysts are still in the experimental stage. The photocatalyst must rely on the irradiation of ultraviolet rays in the sunlight to produce the effect. The use of ultraviolet lamps is easily damaged and replaced frequently. UV damages the human body and plastics.

8, filter adsorption. Hydrophobic crystalline silica molecular sieves are primarily used as filter media. The effect is obvious. Can thoroughly remove benzene, xylene, chloroform and other harmful gases, does not adsorb water and air, can effectively absorb a variety of harmful gases, adsorption capacity, a regeneration can be used for a year and a half. The filter material can be desorption and regeneration using a simple method without generating new sources of contamination. The life span of the material is as long as ten years and thus the maintenance cost is extremely low. It has little effect on reducing the solid dust in the air, and it is more costly than the disposable products of other products.
