Home class 17, extraordinary period, selected air purification equipment, you have a number of key points.

Under aerosols, the market share of Chinese air purification units has increased dramatically, becoming the third largest global market for air purification. Air purification features, appearances and prices vary widely, leaving consumers with a feeling of flux when selecting air purification devices. How can air purification devices be selected? What issues should be taken into account when selecting air purification devices? What is the air purification devices suitable for my current situation? Are they known? Let us come together to understand what follows.

What is appropriate for me

The air purification vehicle is mainly involved in three things: the removal of dust particles, the killing of bacteria, and the removal of acetylene.

First, to determine whether there is a contaminance in his own indoors, and if so, to recommend the purchase of aerosols that are more capable and that many brands of air purification outside the country are essentially ineffective (and, after obsolescence, do not have a cylinder), there are, of course, many products that are beginning to add to China’s special features, buying a hypertension! If pollution is not renovated (or if you think it is not serious), the core function is only to deal with dust, bacteria.

The particles dealt with are: active carbon adsorption, electrostatic dust, and efficient filtering by HEPA.

The bacteria virus is dealt with by the purification of active oxygen, low-temperature plasma air.

Methane is dealt with by molecules, photovoltaic catalysts. In addition, the oxygen plasma is specific to second-hand smoke.

Bearing in mind that you need not every new technology!

Secondly, it would be interesting to know whether additional functions, such as increased humidity, ionizing, oxygen addition, etc., are considered by individuals to be chicken.

Finally, consideration of later maintenance costs, periodic replacement of filtering and additives, replacement of easily impaired components, quality assurance services, etc. are cost-cutting.

It is important to know what is necessary when preparing to buy.

Winds: A good air purification machine must be at a faster rate, i.e., wind, the greater the value is expressed in the product description by (m3/h)cadr.

purification efficiency: selection of products with high purification efficiency can be based on the removal rate of solid particles, the removal rate of volatile organics and the removal rate of acetic anhydride, which are generally expressed in percentage terms, the better the value.

In addition, the filtering network is a core purification device for air purification, with a focus on intent.

Leaching network: the mainstream air purification vehicle consists of three to four floor filters, five to six floors at high altitudes, each of which targets different pollutants.

For example, a front-loading network can absorb small dust particles and smapping;

Leak filters are multi-reactive carbon filters that can remove tastes such as sweat tastes and tastes;

The removal of the leaching network is specific to cadmium;

The HEPA dust filtering network is used to remove micro-granules such as dust, flour, gypsies, second-hand smoke and dust;

The wet filtering network is what has been added.

The lower the cost of the filtering network, the better the purification of the filtering network, but not all of the filtering you need, depending on people and location, primarily on what you want to deal with.

Particular attention needs to be paid to the replacement frequency of the filtering network and the cost of the filtering network for more than one time, depending on the frequency of use and the level of pollution, which, on the basis of experience, is essentially about one third less than the time frame for the cataloguing. A long-term account is required before purchase.

Noise: as long as no more than 30 squares are available, they do not affect sleep, and evenings are used in bedrooms, electing bars with a silent function. Noise under a non-critical model will certainly have an impact on sleeping, which can refer to the voice of non-frequency air conditioners in normal working hours.

Electricity consumption problems: the smaller the capacity of the air purification vehicle, the less the electricity consumed, with the same purification effect. In addition to power, some air purification devices have an automatic model that allows for automatic customization based on indoor conditions, thus allowing for telecommuting purposes and extending the life of the filtering network, and, when purchased, should opt for air purification units with automatic models.

Applicable area: If the size of the house is too large, a better air purification vehicle will not be able to return. It is recommended that an air purification unit of approximately two times the environmental area in which you operate be purchased. Pollutant removal rates marked by brand products are the most desirable data detected in small experimental spaces, and their actual effectiveness in a realistic application environment will be significantly reduced.

Safety — secondary pollution: the use of electrostatic dust and purely negative plasma-generated air purification plants generates ozone, which is often described as secondary pollution of air purification devices. Some ozone kills bacteria, viruses and decomposes gaseous contaminants, but excess ozone is harmful to the body, affects the lung, leads to arsenic and is severely carcinogenic. At present, the most safe and efficient technology is the HEPA network technology and the active charcoal technology, with the production of ozone in electrostatic dusts and pure plasma technologies, and the selection of air purification vehicles using the HEPA network filtering and the active charcoal technology should be selected for purchase. It is also important to recognize 3C certification for the purchase of products from formal plants.

Consolidated consideration of selected purchases

Having taken into account the above, the selection of an air purification device should also be taken into account in a comprehensive manner, such as whether the factory is a specialized factory for the production of aerosols, with a view to distinguishing between the licensed plant; There is no real effect in a real environment; there is no second pollution in safety. In addition, factors such as sex prices, brands, branding power and services need to be taken into account.

Recently, affected by the complexity and uncertainty of the external environment and the frequent occurrence of domestic epidemics, the difficulties of market players, especially small, medium-sized and micro enterprises, have increased significantly. There is an urgent need to take further effective measures to help small, medium-sized and micro enterprises solve their difficulties. According to the “measures to help small, medium-sized and micro enterprises to solve difficulties”, all localities should actively arrange special relief funds for small, medium-sized and micro enterprises and individual industrial and commercial households. In particular, it is proposed that large state-owned commercial banks strive to increase inclusive small and micro enterprise loans by 1.6 trillion yuan in 2022; Give full play to the role of government financing guarantee institutions, expand the service coverage of small, medium-sized and micro enterprises and individual industrial and commercial households, and strengthen the service to small, medium-sized and micro enterprises and individual industrial and commercial households in industries greatly affected by the epidemic; In 2022, the average tariff of broadband and dedicated lines for small, medium-sized and micro enterprises will be reduced by another 10%.

The Ministry of industry and information technology has made it clear that it is necessary to carry out in-depth “benefiting enterprises together” small and medium-sized enterprise service action and small and medium-sized enterprise service month activities, and encourage local governments to take measures such as “enterprise housekeeper” and “enterprise service liaison” to go deep into enterprises to visit and provide services.

The office of the leading group for promoting the development of small and medium-sized enterprises of the State Council is located in the Ministry of industry and information technology.

Analysts pointed out that today’s market decline confirmed our concerns yesterday. But still in that sentence, the decline is not a downward trend, and repeated shocks bottom. After all, the overall support and boost factors of the market remain the same, the logic of the good trend has not been broken, and there may still be repeated under the interference of the current mood. The foundation of the market in spring is still there. Another bottom is still in the process of building the bottom of the market. In this process, it is still a good time for strategic low absorption. While continuing to track the undervalued sector, we can gradually start to pay attention to the oversold growth stocks with high boom.
