Type of air purifier

People who are concerned about indoor air health will certainly not be unfamiliar with air purifiers. There is an air purifier at home, and it is always refreshing to breathe every day. And how much do you know about the working principle and type of air purifier?

First of all, the air purifier is mainly composed of a motor, a fan, an air filter and the like. The working principle is that the motor and the fan in the machine circulate the indoor air.

The polluted air passes through the air filter in the machine to remove or adsorb various pollutants. Some models of home air purifiers also install a negative ion generator at the air outlet (the high voltage in the negative ion generator generates DC negative during operation). High pressure), the air is continuously ionized, a large number of negative ions are generated, and is sent by the micro fan to form a negative ion airflow, so as to clean and purify the air.

Main species

1. Passive adsorption filtration purification principle (filter purification)

The main principle of the passive air purifier is to use the fan to pump air into the machine and filter the air through the built-in filter, which can mainly filter dust, odor, toxic gas and kill some bacteria. The filter screen is mainly divided into a particulate filter and an organic filter. The particulate filter is further divided into a coarse filter screen and a fine particle filter screen.

2, active purification principle (no filter type)

The fundamental difference between the principle of an active air purifier and the principle of passive air purging is that the active air purifier is free of the limitations of the fan and the filter.

It is not passively waiting for the indoor air to be pumped into the purifier for filtration and purification. Instead, it effectively and actively releases the purification and sterilization factor into the air. Through the characteristics of air diffusion, it can reach the corners of the room to clean the air without dead angle.

3, double purification class (active purification + passive purification)

This type of purifier combines passive purification technology with active purification technology.

How to pick the air purifier, I have “three strokes”

How to pick the air purifier, I have “three strokes”

 

I heard that people can live for 7 days without eating, and can live for 3 days without drinking water. But if there is no air, I am afraid I will not be able to live for 3 minutes.

In modern society, with the advancement of science and technology and the development of industrialization, the air we breathe has also been affected and become “unclean”. Not only is the outdoor air polluted, but the indoor air is also “dirty” due to renovations. More and more people realize that our air needs to be purified.

Everyone can’t help but ask, how do you choose an air purifier so that we can breathe safely? Today, Xiaohang gives you “three strokes”:

The first trick: choose technology

The pollutants in the air mainly include particulate matter (such as PM2.5, bacteria, and viruses) and gaseous pollutants (including various odors, formaldehyde or toluene brought by decoration). We need to use different methods to destroy them one by one.

There are two common techniques for removing particulate contaminants:

Electrostatic precipitator

A high-voltage electrostatic field is used to ionize a gas, thereby causing dust particles to be electrically adsorbed to the electrode. The electrostatic precipitator has high purification efficiency and can collect fine dust of 0.01 micron or more. However, electrostatic dust removal does not affect all pollutants, and may also produce ozone, which is harmful to the human body.

HEPA high-efficiency filter

HEPA is an internationally recognized high-efficiency filter material through dense fiber physics to intercept particulate pollutants without secondary pollution. It has been widely used in high-cleaning places such as operating rooms, laboratories and aviation. However, HEPA filters have different grades. Household air purifiers generally use H10-H13 grades. We have to choose a high-grade filter to ensure the effect.

There are two common techniques for removing gaseous contaminants:

Nowadays, the common method for removing gaseous pollutants in the market is to decompose pollutants by adsorption with activated carbon and other materials to ensure that the pollutants will not be released again. There are two common materials:

Photocatalyst

Under the action of ultraviolet light, the catalytic pollutants produce a photocatalytic reaction, which can efficiently decompose pollutants. However, there must be a light source containing ultraviolet light in the process, and if no light is present, it is impossible to exert a cleansing effect. In other words, it is almost useless in a room with low light or at night.

Cold catalyst

It can catalyze a reaction under normal temperature conditions to decompose various harmful gases into harmless substances such as water and carbon dioxide. Therefore, the cold catalyst can also effectively filter the pollutants in the air in a dull environment and can be used anywhere in the home. Of course, to choose a formal enterprise with an authoritative certification, the quality is guaranteed.

Through technical comparison, we found that HEPA high-efficiency filter + activated carbon + cold catalyst can effectively filter particles and gaseous pollutants in the air. Moreover, this combination has a good purification effect, high-cost performance, and no secondary pollution.

The second measure: look at raw materials

Good technology also needs good materials to achieve.

HEPA filter

The enjoyable air purifier selects the highest level H13 filter in the H10-H13 level that is commonly used in domestic air purifiers. After IBR laboratory testing, it can effectively filter the particles of 0.008-micron particles to ensure the purification effect.

Activated carbon

Enjoy the excellent activated carbon air purifier with a surface area of ​​more than 1000 square meters per gram. As shown in the above figure, the activated carbon is magnified many times, and it can be seen that there are many pores for adsorbing pollutants. The pores of 1 gram of enjoyable activated carbon are expanded to an area of ​​more than 1000 square meters, which indicates that the enjoyable air purifier has high adsorption pollution capacity.

Cold catalyst

The Enjoy Air Purifier uses a highly activated cold catalyst that is evenly distributed on the surface of the activated carbon to accelerate the decomposition of contaminants into harmless substances. It can be used at night, and it can also breathe clean air during sleep.

The third measure: look at the standard

The selection of air purifiers also depends on whether they meet the national standards. In response to the chaos of air purifiers in recent years, the state implemented the “new national standard” in March 2016.

As the “new national standard” participating unit, Infinitus has been producing and verifying products in strict accordance with the “new national standard”, and the products have reached the requirements of “new national standard” and “three highs and one low”.

Under the extreme pressure, where is the air purifier market going?

Under the extreme pressure, where is the air purifier market going?

In the first half of 2019, the domestic air purifier market continued its weak trend in 2018. The market participation heat is gradually cooling, and the monitoring data from Zhongyikang is also reflected. In 2019, there were 392 air purifier brands on the market. Compared with nearly 500 brands in 2018, the number of brands has decreased by about 20%. Of these brands, 3/4 are invested in the online market and 1/4 are participating in the offline market.

Due to the weakening of the market demand side at this stage, the two-line market is in a contraction situation. Relatively speaking, the offline market performance is slightly better than the online market. This situation is rare in recent years. The past online market has always been an important driving force for the development of the overall empty net market, and the overall market direction has changed. In the case of online market, reactions are more sensitive. Although the online market sales in the first half of 2019 showed a 30% decline, the sales volume was still significantly higher than the offline market. The online market contributed 62% of sales, while the sales contribution was about 20% lower. It shows that the online market is dominated by the volume, while the offline market products pay more attention to quality, and the higher unit price is still continuing.

From the perspective of market participants, foreign brands are constantly adapting to the competitive pressures of the domestic market, and it is inevitable. Take the online market as an example. In the first half of 2019, 91 foreign brands were sold, accounting for 1/4 of the number of brands sold. Overall, foreign brands feel less competitive pressure than domestic brands, 91 foreign brands have gained about 47% market share, and 278 domestic brands have a market share of 53%. One reason for this result is that the degree of homogenization of domestic brand products is more serious. Domestic brands are indeed stronger than foreign brands in terms of “big dry”, but this is also a double-edged sword, due to the technical capacity reserve. Insufficient, the proportion of domestic brands using activated carbon and HEPA filters is 20% and 30% higher than that of foreign brands respectively. The technical homogenization combined with the lack of innovative design has affected the brand recognition. Foreign brands are diversified in the choice of purification technology, using a higher proportion of ion technology (high-voltage static electricity, nano-water ions, etc.), in addition to a small number of washing, ozone, ultraviolet, and other purification and sterilization technology.

Technically, domestic brands have no overall advantage, but they have not hindered access to market cakes. Domestic brands outperform foreign brands in product intelligence performance. APP remote control models have a penetration rate of more than 70%, far higher than foreign brands. The product control is convenient for the domestic brand purifier to occupy a clear advantage, and in turn to obtain a better product experience for consumers. It can be said that the two camps have their own advantages, and they are also learning from each other and learning, which has greatly improved the functionality and cost performance of the products.

Convenient handling is indeed attractive to the family of the best household air purifiers, but it is only convenient to operate, but not enough to reverse the current market development trajectory. Failure to achieve significant breakthroughs in products is a major obstacle to the iterative upgrade of the air-net industry. Although in the past year, in addition to the net consumption of formaldehyde in the market, some consumers have paid attention to it, it has not been able to effectively activate the consumer demand side. Compared with the internal driving force of panic buying due to the fog and the city, the gap is huge.

The Olansi room air purifier needs to be repositioned, which will be crucial for the future development of the empty net market. There are two kinds of trends in the market that are worthy of attention: First, cross-border winds, “warm air + purification”, “humidification + purification”, “dehumidification + purification” environmental electrical appliances emerge one after another, their emergence is breaking the consumer’s inherent environmental home The cognition of the single function of electrical appliances; the second is the deepening of the purification function, from the removal of gaseous pollutants such as mites and formaldehyde, to the comprehensive consideration of odor, allergens, and mites. Behind these features is the result of the refinement of the consumer home product application scenario, which needs to be implemented based on the technical capabilities of the enterprise. Therefore, the cultivation of internal work of products is an effective means to break the solidification of the industry. The market is in the adjustment period, which provides a favorable market environment for the prepared enterprises. When the tide recedes, it is known who is in the nude swimming, and the empty net industry needs to conduct a necessary examination of its own development. Only when the market has undergone an adjustment period will face more opportunities in the future market development opportunities.

Is the air purifier useful? The focus when buying an air purifier!

No matter what brand of large room air purifier you buy, you must first figure out which area you are using, whether it is used for dust removal, sterilization or other, and you should choose according to different areas and prices that you can accept, such as a room. If it is relatively large, you should choose an air purifier that purifies the air volume per unit time.
Today, I will talk to you about the key points of choosing a large room HEPA air purifier. If you are ready to buy or have a need to buy, you can refer to the reference!

The key points you should know when purchasing an air purifier
quality
The quality of the product is the guarantee for the long-term normal operation of the product and the effect. Therefore, when selecting the air purifier, you must choose an air purifier with product quality certification. It is best to check whether it has a quality certification report. It is said that the quality of well-known brands is relatively guaranteed, and this is also the necessity of a simple understanding of the question of “what brand of air purifier is good”.
Filter
The filter has four main functions: filtration, adsorption, decomposition, and humidification. The types of filters include pre-filters, washable deodorizing filters, formaldehyde removal filters, dust collection filters, and humidifying filters. When choosing an air purifier, remember to ask the type of business filter and the number of layers it has, and the design, manufacturing process, materials, formula, and ventilation area of ​​the filter determine the effect of the machine purifying the air.

noise
Each brand of air purifier has different wind speed design, so the noise generated during its operation is also different, but in general, the machine will feel the sound is very low when the machine is running, and the sound is running at high speed. It is relatively large, so when choosing an air purifier, you can first try to see if the sound decibel emitted by the machine during high-end operation is within the acceptable range.
power consumption
The electric power of the air purifier during operation is the basis for judging the amount of power consumption. The larger the general air volume and the larger the purifying area, the larger the electric power required, and the power consumption will, of course, be larger.
price
Nowadays, there are many brands of air purifiers on the market, and the price is also chaotic. Therefore, when choosing an air purifier, the price is also a very important factor, if the air purifiers are excellent in product quality and purification effect. The selling price should be determined by the applicable area certified by the authoritative testing department. The larger the applicable air purifier, the higher the price.
Tips
Of course, in addition to the five aspects mentioned above, it is necessary to focus on understanding, and other things can not be ignored. For example, the formaldehyde removal rate, air volume, and purification area of ​​the air purifier are only comprehensively understood by the air purifier. I don’t think that “the air purifier is useful” or “what brand of air purifier is the best” before buying an air purifier.
