Deep mite removal and turbidity reduction make the purification more effective. Patented double air duct and double circulation, four in and four out strong purification, large-sized apartment is also enough.
First, then, why choose an air purifier?
All kinds of troubles are eliminated, and there is no trouble in healthy life. The benefits of air purifiers can be seen from the following points.
1, remove dust, solve floating powder, dust and other particles in the air, and bid farewell to allergies.
2. Remove harmful substances and effectively absorb residual formaldehyde in decoration.
3, remove indoor odor, effectively eliminate the odor caused by oil smoke odor, pet odor and moldy and rotten items.
4, urbanites, air conditioning in summer, heating in winter, indoor air conditions need to be improved.
Second, the principle of air purifier
Simply put, the air purifier is to use the mechanical motor and exhaust fan installed inside to promote the air flow, remove the adsorbed inferior gas through the filter screen and send it out by the fan, thus achieving the purification effect.
The configuration and performance index of internal machinery naturally become the reference index of purification ability.
Third, the dry goods and misunderstandings of purchasing air purifiers
Here comes the key part! The ultimate meaning of buying electrical appliances is to be practical, to have what you need and to have your strength guaranteed. From the following points, we can see the usage and precautions of the purifier, and choose the air purifier that suits you best.
1, CADR (clean air output ratio)
CADR is the output ratio of air purifier obtained by American home appliance authority according to strict test. The card value represents the cleaning efficiency of the air purifier. The higher the card value, the better the cleaning effect of the air purifier.
Therefore, to choose an air purifier with a CADR value suitable for family size, the area use formula can help, that is, the CADR value is converted into room area, and the card: house area = 5: 1.
Then, after choosing a room suitable for 50 square meters and measuring the height of the room to be 4 meters, what is needed is a CADR of 50 * 3 * 5 = 750 m? /h purifier.
In addition, according to different pollutants, the card value can be divided into solid card and gas card. Solid cards are particle cards such as dust and powder, and gas cards are gas cards such as formaldehyde, hydrogen and carbon.
2. CCM (Cumulative Purification Index)
CCM value is an important index of reference filtration function, which can also be divided into gaseous CCM (formaldehyde and other gases) and solid CCM (particulate matter). The higher the CCM value, the longer the service life of the filter.
The formaldehyde value of CCM is divided into four grades: P 1 to P4, and the particulate matter of CCM is divided into four grades: F 1 to F4. The bigger the number, the better the function.
In daily purchases, merchants often only show grades and rarely see value. This is because the detection process of CCM needs to spend a lot of investment to meet the needs of commodity grade standards, so the detection process is omitted.
For people who have different gas and particle removal requirements and can't compare CCM values, they can choose the control card value according to their own needs.
3. Energy efficiency rating
The energy efficiency grade is a standard to judge whether the purchased household appliances are energy-saving. The grades of household appliances can be divided into 1 to 5. Grade 1 stands for the best and highest grade of energy saving effect. Grade 5 represents products that meet production standards, and products below grade 5 are unqualified products.
Efficiency grade is a good reference when considering the power consumption of purifier. The maximum power of air purifiers on the market is only about 100. Even if it is used for 24 hours, the daily electricity bill in China is about one yuan, which is acceptable to most people.
Therefore, when buying an air purifier, you can buy it according to the energy efficiency level. The higher the energy efficiency level, the more energy-saving the machine.
4. Noise
According to the index of the card corresponding to the noise value of air purifier in the new national standard, when the card value is about 150-445 m? /h, noise control below 60 decibels. When the card value is greater than 500m? /h, noise control below 70 decibels.
The sound emitted by purifiers on the market is about 25-65 decibels, and the highest level of 65 decibels is close to human voice. Without 24-hour high use, it will not affect life.
Can be used according to different purposes and time periods. For example, when the decoration odor is eliminated, the high-grade lasts for 2-3 hours. When purifying the cooking fume on the holiday table, it can be reduced for 4-6 hours.
5. in addition to formaldehyde's method
The air purifier removes formaldehyde by decomposing, adsorbing and transforming pollutants in the air.
Removing harmful gases such as formaldehyde is the main purpose of air purifier and the core part of purifier design, in which the filter system of purifier plays an important role.
At present, the most supportive method to filter formaldehyde and other gas pollution is the adsorption of activated carbon.
The materials of activated carbon can be divided into powder, column and coconut shell activated carbon. When choosing the filter screen, if you want to know the removal degree of formaldehyde by the filter screen, you can refer to it-the adsorption effect of activated carbon without any substance is better than that of activated carbon with other substances. However, whether there is a pure activated carbon filter screen in the market needs to be considered, and it can be judged according to the degree of activated carbon when purchasing. After the selection is completed, it is necessary to pay attention to replacing the filter element regularly.
6. Disinfection method
The sterilization methods of air purifiers can be divided into the following categories:
Electrostatic precipitation (ozone sterilization, but the degree of ozone control needs to be improved).
Negative ion adsorption sterilization (it has certain sterilization effect, but it will produce ozone to avoid long-term use).
UVB ultraviolet lamp is used for sterilization (it can destroy limited viruses).
Lysozyme (need to be used with filter screen to reduce virus activity and sterilize).
H 1 1 and above (physical filtration can effectively intercept germs).
Copper ion reactor filter (on the basis of interception, it can kill germs quickly and has better protection).
For the common germs in current life (viruses that cause common colds and respiratory infections), the stacked filter can achieve the sterilization effect. When choosing the filter screen, you can know the sterilization ability of the air purifier through the filter material.
7. Applicable area
The applicable area is closely related to the first point CADR.
The higher the card value, the better the cleaning effect. However, the higher the card value, the better the purifier. At present, the card value of purifiers on the market is between 300 and 400, and the highest is about 800. The purchase shall be based on the actual use area (use area = card * 0,07-0, 12).
For example, if you choose a card 400 air purifier, the usable area can be about 28-32 square meters. Therefore, if you only need the use effect of the current area, it is often unnecessary to buy a purifier with a higher card value.
When considering the space for family use, you can choose the largest room in the family to facilitate the applicability of other rooms. Only by choosing the one that suits you can you buy the right one.
8. Air duct structure
The structure of purifier is related to the design of air duct and purification effect. The tuyere design of air purifier should ensure the operation of adsorption mode, and most of them are placed on the back of the machine.
In general, the front is the air outlet, so the back is the air inlet position. This design can properly adjust the positions of the upper and lower sides and the back after determining that the front is the air outlet. However, in addition to the design of the rear air inlet, the addition and replacement of other positions will make the operation of the air purifier complicated, inconvenient and simple. Moreover, the upper and lower air inlets are prone to fouling.
Air duct structure of air purifier
Therefore, it is suggested to choose the design of air inlet at the back and air outlet at the top, which can not only ensure high energy saving and effective card value, but also clean and reduce noise, making it convenient to place at will.
9, interactive way
At present, the interaction modes of air purifiers on the market are mostly: button type, touch screen type, APP remote control, AI voice remote control or 24-hour intelligent control and so on. Different operation modes have different conveniences. It is better for the elderly and children to choose the button type or the touch screen type, which is simple and convenient to use.
If we use it ourselves, it is recommended to choose APP remote control or 24-hour intelligent control, which is intelligent and convenient and more in line with our life rhythm. If large families use it together, it is recommended to choose multi-mode interaction, which can be used by both the elderly and young people to reduce trouble.
9. Additional functions
In addition to the good purification effect, the additional functions of the air purifier are also very important. The more practical the additional functions of the air purifier are, the better our sense of use will be. Simply recommend several useful additional functions to sisters:
(1) Filter replacement reminder
During use, pollutants will accumulate on the HEPA filter element. When pollutants accumulate to a certain amount, the HEPA filter will fail and the purification effect of the air purifier will be greatly reduced.
The filter element replacement reminder function is to remind us when the filter element accumulates a certain amount of pollutants, so that we can replace the HEPA filter element in time. That is, it reduces the possibility of waste caused by premature replacement of HEPA filter and avoids the failure of HEPA filter. This function is completely gospel for the air purifier Xiaobai!
(2) Design of safety child lock
This design is super suitable for families with children!
Children at home are always groping, and each set of purification mode will always be messed up by their own little baby, which makes people feel distressed. And the safety child lock is designed to solve this problem! When we long press the child lock function on the display panel, the buttons on the panel will be locked, and children will not mess up the purification mode!
