How to choose an air purifier for children?

There are two mainstream technologies on the market: mechanical and electrostatic, for each different source of pollution, such as particulate matter, or formaldehyde, etc., the filter has different filtration efficiency, and the air purifier has different CADR values. Therefore, if the corresponding pollutant is not mentioned in the nominal, the manufacturer is also suspected of fishing in troubled waters.

The whole machine is imported originally, including every small part. It is a world-class brand, leading in international sales (more in the country, not counting in the country), and there are many authoritative certifications from world authoritative institutions and associations.

Start by choosing a purification technology: mechanical, electrostatic, or "hybrid" (a modified version of mechanical), one of which is usually chosen by a brand. The choice of brand should first consider manufacturers specializing in air purifiers, rather than well-known manufacturers who do everything, and the probability of OEM production of these well-known manufacturers is relatively high, and specialized manufacturers generally have their own core technology.

A truly professional air purifier brand is aimed at different spaces, not crowds. The brands aimed at the crowd are all pseudo-brands, because all people have the same requirements for air quality, and there is no problem that pregnant women, children and the elderly are more demanding.

The technology of the space within 30 square meters needs to consider the absence of ozone, silence, physical purification and safe sterilization. Within 50 square meters, it is necessary to consider physical purification without ozone. Within 100 square meters, it is necessary to consider the purification efficiency.

Larger spaces need to consider efficient purification and low-cost maintenance.

Identify your needs. Whether it is to remove particulate matter, or particulate matter and odor, or allergens, or formaldehyde, this should be considered clearly. Another factor is the matching of the size of the room and the applicable area.

Because the purification capacity of an air purifier is always limited, and the indoor air circulation is also quite limited, generally speaking, it is necessary to put an air purifier in every room that needs to be purified. Of course, the tricky way is to drag the air purifier wherever the person is in the room, such as putting it in the living room during the day and the bedroom at night.

Considering the cost of use, there are mainly three parts, one part is the electricity fee, one part is the consumables, and then the maintenance and repair. It's easy to understand that air purifiers are meant to run around the clock, and the cost of electricity consumption will account for a larger proportion as time is used. Consumables mainly refer to the filter, and the cost of purchasing the filter is different in different brands and models.

The cost of maintenance and repair is mainly to examine the after-sales service provided by the manufacturer. After all, the reliability of this thing is very important, and it is to be used for a long time after it is bought, stable and reliable long-term operation, and warranty service once there is a problem, are more important points.

Air purifiers are not cheap, and they are unlikely to be. So when choosing, don't fall for some black-hearted manufacturers because of greed for cheapness. If you feel that this is a profiteering industry, what you can do as a consumer is to make your own wise choice, let the industry compete in an orderly manner in the market, eliminate manufacturers of unfair competition, and gradually form a mature system, in the long run, this is conducive to the development of the industry and the practice of benefiting consumers.

Security. As a family with children, safety is very important, try to choose an air purifier with child lock function to ensure the safety of children.

Brand. Generally speaking, the performance, function, and quality of air purifier products of big brands are relatively more guaranteed.

Filtering effect. Generally speaking, air purifiers are equipped with filtration functions, and when choosing, you need to pay attention to the filtration effect they label, the higher the better. In addition, the filtration level of the filter is also an aspect of the filtration effect.

Other functions, if any, such as the filtration of gaseous pollutants such as formaldehyde, should also be focused.

Noise level. The less noise, the less impact it has on the life and rest of the people indoors, especially children.

Energy consumption. The lower the energy consumption for the same filtration effect, the better.

For purifiers used by children, first of all, choose a big brand with a price of more than five or six hundred yuan, and take a look at the purifier, whether it is suitable for children, if it is not suitable, don't buy it.

Choose the best, well-branded, high-quality air purifier within your own capabilities. If you buy an air purifier, you need to pay attention to some precautions: the filter should be replaced regularly; Clean the filter regularly to prolong the service life; The effect of indoor centering is better; Close doors and windows while the air purifier is running.

We recommend the German O2U, a brand that originated from a German technology company focusing on air purifiers, and has won a number of American and European design awards. In particular, the air purifier for children's dolls developed by it is Air Family, which is sought after by parents. This purifier is shaped like a doll and a doll, and the HEPA13 high-efficiency air filter is built into it, which can remove particles with a diameter of less than microns.

And the doll material is super soft, it is a Chinese 3C certified product, with extremely high safety performance, children can take it with them wherever they go, and breathe fresh air anytime and anywhere.

Hello dear, 1Consider the effective purification capacity of your air purifier: First, you need to understand the differences in the effective purification capacity of different air purifiers and determine the noise level you need.

2.Consider the size of the area you need: To ensure effective purification by your air purifier, you also need to know the size of the area you need to clean, as well as the amount of capacity you need.

3.Consider filtration: It's also important to choose the right air purifier that can effectively filter out a wide range of pollutants.

You should determine the required filtration energy mode slip force according to your actual situation, such as pollution source, ambient temperature, etc. 4.Consider ease of use:

The air purifier also needs to be easy to use, and you can decide whether you want to plug it in or use special features such as silent operation depending on your actual needs. 5.Consider after-sales service:

In addition to the above functions, the after-sales service of the air purifier is also essential, which is also a necessary factor to consider when buying an air purifier. Take the shot.

Summary. 1. Choose according to the size of the room: First of all, you need to choose the right air purifier according to the area of the room, generally speaking, 90 cubic meters is best for a room within 10 square meters, 110-130 cubic meters for a room within 10-25 square meters, and 160 cubic meters for a fast purifier for more than 25 square meters.

2. See the filter screen on the market: The filter screen of the air purifier can be selected according to the actual situation, generally speaking, the common ones on the market are electrostatic precipitator screen, activated carbon screen, HEPA, oxygen reduction, and photocatalyst. Of course, the most important thing is to determine the level of the filter according to the degree of pollution of the air itself.

3. Select the characteristics of the purifier: the frequency of the air purifier should be selected appropriately, generally speaking, 40-70 volt ampere can meet the purification needs of most of the home environment, in addition, it is necessary to check the electrostatic precipitator adsorption capacity, noise, internal structure, etc., these characteristics will also affect the effect of the air purifier. I hope mine is helpful to you and I wish you a happy life!

How to choose an air purifier.

Can you tell us more about that?

1.

The frequency of the air purifier should be selected appropriately, generally speaking, 40-70 volt ampere can meet the purification needs of most home environments, in addition, it is necessary to check the electrostatic precipitator adsorption capacity, noise, internal structure, etc., these characteristics will also affect the effect of the air purifier. I hope mine is helpful to you and I wish you a happy life!

The methods of choosing an air purifier are: look at the CADR value, look at the CMM value, look at the energy efficiency of the purifier, look at the noise value, look at the functional needs, look at the use scenario, etc.

1. Look at the CADR value.

CADR is a direct indicator of purification efficiency, which means "clean air output ratio". The unit is m h, and the higher the CADR value, the more air is purified per unit time, and the better the purification effect.

2. Look at the CMM value.

CCM stands for Cumulative Purification Volume. Its unit is milligrams, which can be simply understood as the dust holding capacity of the filter. CCM can also be expressed as the durability of the filter, which is the total amount of contaminants filtered over the life of the filter.

The higher the CCM value, the longer the life of the filter and the better the filtration effect.

3. Look at the energy efficiency of purification.

Purification efficiency is the ratio of CADR's clean air volume to rated power. Indicates the amount of clean air generated by the unit power consumption of the air purifier in the rated state, which is divided into particulate matter purification energy efficiency and formaldehyde purification energy efficiency. For the energy efficiency value of particulate matter purification, 2 is qualified and 5 is high efficiency; For the energy efficiency value of formaldehyde purification, it is qualified level and 1 is high efficiency level.

4. Look at the noise level.

The noise level of an air purifier refers to the amount of sound generated when the air purifier reaches the maximum CADR value during use. Generally speaking, as the CADR value rises, the noise level of the machine will increase accordingly.

5. Look at the functional needs.

For example, users in the north can choose an air purifier with a humidification function, and families with children and elderly people can choose an air purifier with a sterilization and antivirus function.

6. Look at the use scenario.

For example, users who often drive can choose a car air purifier, and Yuxin users who stay at a desk or desk for a long time can choose a desktop air purifier.

Summary. Hello, dear. Here's how to choose an air purifier:

1.According to the applicable area of the family, the applicable area of the air purifier of different power is different, if the room is large, you should choose an air purifier with a large air volume per unit time. For example, a 25-square-meter room should use a purifier with a rated air volume of 200 cubic meters per hour, and a room of about 50 square meters should choose a purifier with a rated air volume of 400 cubic meters per hour.

Every product will have this parameter, so be sure to look at it before you buy. 2.According to the purification function, the desired function is selected according to the air environment of the house and the appropriate purification effect.

The functions of air purifiers are mainly purification, sterilization, filtration, humidification, etc., and different products will have multiple functions.

Hello, dear. Here's how to choose an air purifier:1

According to the applicable area of the family, the applicable area of the air purifier of different power is different, if the room is large, you should choose an air purifier with a large air volume per unit time. For example, a 25-square-meter room should use a purifier with a rated air volume of 200 cubic meters per hour, and a room of about 50 square meters should choose a purifier with a rated air volume of 400 cubic meters per hour. Every product will have this parameter, so be sure to look at it before you buy.

2.According to the purification function, the desired function is selected according to the air environment of the house and the appropriate purification effect. The functions of air purifiers are mainly purification, sterilization, filtration, humidification, etc., and different products will have multiple functions.

3.According to the purification method, the purification method is mainly divided into three categories: HEPA (high-efficiency air purification), nanoe (nano water ion), and plasma cluster space.

4.Convenience of maintenance Before purchasing, it is necessary to understand whether the air purifier is convenient to clean, the general air purifier only has a rough filter that needs to be cleaned by itself, and other components generally need to be replaced or repaired by the repair company. This should be confirmed before purchasing.

5.Sustainability of useWhen buying the product, we should pay special attention to its service life, although it is not required to be used forever, but at least the most basic service life should be guaranteed.

It is recommended to consider Philips or Panasonic, foreign products are relatively reliable, but they are a little more expensive.

Brand, technology, purification effect Whether there is secondary pollution.

Needless to say, the more reliable the brand, the more trustworthy the product quality.

In terms of technology, there are many technologies used in purifiers, and traditional filter-type air purifiers are being phased out step by step.

Purifiers made according to chemical principles, generally such products can be used with humidifiers, ** more expensive, less secondary pollution, but from the concept of environmental protection, filters made according to chemical principles are not environmentally friendly, and there are many debates in the purifier industry. According to the principle of active sterilization of these products, they can be divided into silver ion technology, negative ion technology, low-temperature plasma technology, photocatalyst technology and pure ion cluster ion technology.

1.Silver ion purification technology.

Lawrence's technology in the 80's of the 20th century, the cost of silver-loaded sterilization alone is high, and the filter element is frequently replaced, and now the silver ion technology is not used alone.

2.Electrostatic adsorption technology.

The main principle is the use of electrostatic release ions, adsorption of concentrated dust in the air to reduce dust, has a certain killing effect on bacteria, but easy to produce ozone and other derivatives, the advantage of this kind of products is that the production cost of products is low.

3.Low-temperature plasma technology.

The main principle is that by applying an external voltage to the gas to the discharge voltage of the gas, the gas is broken down, and various low-temperature plasmas with strong oxidizing properties are generated, and the pollutants in contact with it are decomposed in a very short time. As for the negative effects of this technology, major brands have different evaluations, and it is difficult to determine which is better or worse.

4.Photocatalyst technology.

Photocatalyst is actually a technology that uses semiconductors to release free radicals with strong oxidizing power under the irradiation of light. The advantage of this technology is that the product cost is low, and the disadvantage is that the free radical activity leads to a shorter residence time in the air, and the killing effect on viruses and bacteria is also limited.

5.Eco-grade negative ion technology.

Eco-grade negative oxygen ions are generated through cutting-edge technologies such as negative ion converter technology, nano fuiierene negative ion release technology, and ecological anion chip technology. Eco-grade negative oxygen ions have small particle size, high activity and long migration distance, which can actively capture dust, particles and even other pollutants in the air, and can kill bacteria and viruses at the same time, with a removal rate of more than 99% for formaldehyde and other pollutants, which is the safest and most effective air purification method at present.

The test report of the Institute of Health-related Product Safety of the Chinese Center for Disease Control and Prevention determined that the air anion generator can effectively eliminate the hazards of particulate matter that can be fed, and the negative oxygen ion generator does not need a filter or a fan, but removes small particles in the air by releasing negative ions, thereby significantly reducing the number of bacteria and viruses harmful to the human body and particles in the air. Developed countries in North America have long used negative ion technology to eliminate the hazards, and have achieved good results.
