Which is better for air purifiers? What kind of air purifier is good?
The times are developing, science and technology are improving, and people’s living conditions are getting better and better. However, the air quality is getting worse and worse. The long-term influx of unclean air will affect our health. Therefore, we choose to use best room air purifier cigarette smoke. The people are not in a minority, so what kind of air purifier should we buy? Today, Xiaobian will tell you which air purifier is better.
Different filter grades, the purification effect is very different. The higher the HEPA network grade, the smaller the diameter of the particles that can be filtered, and the better the filtration effect. At present, the common air purifiers on the market use H10H9 grade HEPA nets. The mid-to-high end air purifiers generally use H12 grade HEPA nets. Very few high-end air purifiers use H13 grade HEPA nets. The H13 grade HEPA net is a top-grade imported medical grade CleansingSoftHEPA filter with good filtration. Therefore, at least the air purifier with HEPA network level above H12 should be selected, and the air purifier with H13 level HEPA net should be selected as much as possible.
Which is better for the air purifier? The larger the amount of air cleaning, the larger the purification area.
The larger the air cleaning amount (CADR), the larger the purifying area of the air purifier, and the more the number of purification cycles. The international standard is 5 times an hour. For example: there is an air purifier with a clean air volume of 450m?/h, which is calculated by the room height of 3 meters. The area of the air purifier is: 450÷5÷3=30 square meters. When purchasing, consider whether the clean area of the air purifier matches the room area. If the clean area is smaller than the room area, the expected clean effect will not be achieved. Therefore, you should try to purchase an air purifier with a large amount of clean air. .
Which is better to buy an air purifier – choose a quiet air purifier
The noise problem is a problem that is often encountered during the use of the air purifier. When purchasing, the noise problem should be considered mainly from the following three aspects: whether the sleep mode can really achieve ultra-quiet; when the maximum air volume is generated Whether the noise can be tolerated; whether the noise in the automatic mode is acceptable. Some purifiers use DC brushless ultra-quiet motor and additional silent cotton technology to effectively reduce noise. At the time of purchase, air purifiers with both mute techniques can be prioritized.
Which is better for the air purifier? The higher the purification efficiency, the better the air purifier.
In addition to considering the one-time purification efficiency, consumers should also consider the purification efficiency of the whole machine, that is, the air purification amount, otherwise it will easily fall into the trap of the merchant: for example, purifying the same volume of air, one-time purification of two purifiers The efficiency is 99%, but the purifier A takes 1 hour, the purifier B takes 2 hours, obviously the purification efficiency of A is higher than B, but the merchant does not mark the test parameters, you see all It is a 99% purification rate. In addition, the efficiency of the air purifier in addition to PM2.5 and formaldehyde removal are different, and the value of both should be considered comprehensively at the time of purchase. Finally, it is necessary to consider that the values of purification efficiency are all tested in a manufacturer-specific experimental environment. Since the indoor air environment is different from the laboratory environment, consumers should not blindly listen to the manufacturer’s virtual standard value when purchasing, but See if the effect is really effective.
Nowadays, many people wear masks for fear of inhaling polluted air. If the air quality in the home is not up to standard, you may wish to purchase an air purifier to purify the air by using an air purifier. When considering various aspects, only the selection of high quality air purifiers can help us to improve air quality quickly.

Many people buy best room air purifier cigarette smoke to purify indoor air in the haze. With the arrival of summer, the foxes are also temporarily away, so is it necessary to use air purifiers?
The answer is yes!
In fact, the air purifier is not only to prevent smog, the large room air purifier for smoke also has the function of removing indoor pollution, formaldehyde, bacteria, pollen and so on. And you know?
Summer indoor air environment may be worse than winter!
In summer, the weather is hot, and people use air conditioners for summer.
However, although the air-conditioning is cool, but the doors and windows are closed all day long, not only the humidity is very large, but also the indoor air is not circulated, causing the indoor air pollution to cause various discomforts, chest tightness, coughing, sneezing and the like.
The report of the Indoor Environment Monitoring Center of the China Interior Decoration Association also confirmed that indoor air pollution testing in summer will be about 20% higher than other seasons.

Because summer is the season of bacterial reproduction, in addition to directly entering our body, these bacteria can enter our body by attaching particles and dust with a diameter of less than 5μm.
Even through our speech, coughing, sneezing, etc., pathogenic microorganisms in the mouth, throat, organs, and lungs are easily transmitted to other people through the air, such as some epidemics caused by the spread of germs.
3
Increased formaldehyde volatilization rate
As the summer temperature increases, the volatilization of indoor pollutants also increases significantly.
According to the statistics of the health department, the humidity increased by one degree, and the concentration of formaldehyde and benzene released from furniture increased by 015 to 0.37 times.
The pollutants in the home are not released in a short time. It takes 15 years to completely release the cleanliness. It is best to avoid the summer and then move to the new house. The elderly and pregnant women need to pay special attention.
1. Ventilation and ventilation. You can open the window when the temperature is not so high every morning and evening, as long as 2 hours can greatly reduce the concentration of indoor pollutants.
For long-term use of air-conditioned rooms, new renovations, and rooms with new furniture, pay special attention to window ventilation every day.
2. Use an air purifier. Air purifiers are the most effective way to improve air quality.
It can effectively filter dust, bacteria, toxic gases, etc. in the air. Don’t worry about the summer air purifier need to be used?
In fact, in today’s environment where the environment is not very good, many harmful gases, substances and germs are often around us.
Using an air purifier, it is indeed essential to create a healthy air environment for the family and yourself.

Environmental regenerator purification technology
HEPA’s highly efficient and quiet multi-layer progressive filtration technology removes all kinds of pollen, dust mites and other allergens in the air as low as 0.1 micron by electrostatic and physical adsorption;
Multi-filter technology (composite filter) can effectively inhibit, filter and disintegrate pollen, insects, second-hand smoke, fungi, formaldehyde and other suspended particles. The application of cold catalyst technology combined with PM2.5 and ash-specific filtration can make the filtration, purification and sterilization efficiency of 0.3 micron particles high.
Multi-filter technology can effectively inhibit, filter and disintegrate pollen, insects, second-hand smoke, fungi, formaldehyde and other suspended particles. The application of cold catalyst technology combined with PM2.5 and special filtration of ash can make the filtration, purification and sterilization rate of 0.3 micron particles up to 99.97%.
360 degree wind direction, three-dimensional circulation purification of the surrounding air, so that the negative ions generated by the machine spread to every corner in the surrounding area at the fastest speed, the negative ion purification effect is good (the reason for the fresh air in the forest is because there are more negative oxygen ions in the air)

12 questions and answers about smog and air purifier
Today we have summarized 12 issues that everyone cares about and are related to smog, to answer them one by one.
NO.1
Do you want to open the window in the fog?
A: Of course not.
Some people say that the fog is coming, the air quality in indoors and outdoors is similar, and it is not as good as ventilation through windows.
This statement is wrong. In the case of normal closing of doors and windows in foggy days, the indoor PM2.5 concentration is nearly half lower than that of the outdoor. Friends with top rated air purifiers for large rooms can see it from the test data. Opening the window will allow the outdoor high concentration of harmful particulate matter to enter the home without any obstacles, seriously affecting the indoor air quality and threatening our health.
Secondly, most people use heating/air conditioning equipment or humidification/dehumidification equipment at home. Ventilation of the window will cause heat/cooling loss and humidity imbalance in the room, which is not energy-saving and environmentally friendly.
Therefore, our solution to the people in the smog area is “a fresh air system with filtering function + a reasonable number of large room air purifier for smoke”.
NO.2
What is a fresh air system?
A: The fresh air system is a kind of home appliance that can continuously deliver fresh air to your home and discharge indoor dirty air. It can continuously change indoor air, let the indoor air flow and keep fresh.
The fresh air system mainly has three types: central ceiling pipe type, wall type and cabinet type.
The central ceiling pipe type can be hidden in the ceiling, the fresh air effect is better, but the price is relatively high, and the installation design requirements are also relatively high. Wall-mounted and cabinet-type are non-pipeline fresh air systems, which are divided into one-way flow and two-way flow.
The working mode of the new fan in one-way flow can be understood as only entering the air. The air is continuously drawn in and then the dirty air in the room is squeezed through the window slit and the door seam, and there is no independent exhaust outlet.
The two-way flow of the new fan can be understood as having the presence and exit, while the air is continuously pumping in, and there is also a separate exhaust vent to discharge the dirty air.
NO.3
What is the difference between an air purifier and a fresh air system? How should I choose?
Answer: The air purifier is responsible for purifying the indoor air. It is the inner circulation. The fresh air system is used to filter the outdoor air and then pump it into the room to realize air circulation and increase the indoor oxygen content.
At present, the fresh air system in China is based on the current state of air quality, the filtration level has been improved, ventilation and ventilation can also maintain a good filtration effect.
If the local air quality is relatively poor, it is recommended to buy both the fresh air system and the air purifier. The fresh air system can be turned on 24 hours a day. When the indoor and outdoor air quality is relatively poor, both of them are turned on at the same time.
NO.4
Why are there so many differences in the appearance of the air purifier? Which one is more suitable for the family?
A: These differences are caused by the structure of the air purifier. For households, a purifier with a double inlet structure is more recommended.
At present, the air purifiers on the market can be roughly divided into four types: half-tower, tower, box, and double-inlet. The reason why the double-intake is more recommended is because its structural advantages are obvious.
Its air duct is very short and direct. The sides of the machine are large-area filters and enter the wind at the same time. The air is not blocked too much and is quickly blown out from the top of the machine with lower noise. In particular, it maintains a high air purification efficiency (CADR value) even when the minimum wind is applied, which is more suitable for the family to open 24 hours, and the lower noise will not interfere with family rest.
Moreover, its price is moderate, the price of the family version is generally around 5,000 yuan, compared to the tower price of about 10,000 yuan or so.
NO.5
Is the higher the CCM value of the air purifier, the better?
A: Not the higher the better.
The CCM value represents the service life of the air purifier filter. The home environment is relatively small and does not require too high a CCM value.
It is best to end the smog season every year, the filter screen is almost dead, and replaced directly. Otherwise, when the season of the purifier is not very good, the filter screen will be delayed and not replaced, and the harmful substances inside will be easily mildewed and deteriorated, causing secondary pollution.
When purchasing an air purifier, you can directly purchase a family model. Do not blindly pursue high-end business choices. The best is the best.
NO.6
Can buying an air purifier solve all indoor air pollution problems?
A: No.
The main function of the air purifier is to purify indoor particulates through a HEPA filter. Some high-end purifiers also have activated carbon and other purification media, which may have a certain purifying effect on formaldehyde and some volatile organic compounds with odor.
But in fact, formaldehyde is only a kind of indoor harmful gas. You may also breathe a series of toxic or even carcinogenic gases at home, such as TVOC (total volatile organic compounds), strontium, ammonia and so on.
According to the World Health Organization’s 2016 data, indoor air pollution kills 4.3 million people worldwide each year, 600,000 more than outdoor pollution. Indoor harmful gases have exceeded the pollution of outdoor particulate matter and become an important factor threatening our health.
For these harmful gases, air purifiers alone cannot solve them.
The best way to solve indoor air pollution is to avoid using too complicated building materials, try to buy large brands of home improvement products, and ventilate the air. If there is no window opening condition, you can install a fresh air system, which can not open the window. Under the 24-hour ventilation.
NO.7
What kind of mask can prevent smog?
A: It needs to meet certain standards. There are three main types of identification for these standards.
N95. The well-known N95 is not a specific product name. It is a mask classification of the US standard, that is, in the US NIOSH (National Institute for Occupational Safety and Health) standard, “filtering non-oily particles is more than 95% efficient” and passed A type of mask reviewed by NIOSH.
NIOSH has conducted a series of research and specifications on respiratory protection products since the 1980s and is now continuously updated. For PM2.5 granules, or to protect against some of the disease spread through the air, this can be achieved with a N95 mask.
▲ US NIOSH standard
KN90. On some packages you can see the words GB2626-2006 KN90, which is the Chinese standard established in 2006.
According to the GB2626-2006 standard, our country uses sodium chloride aerosol to represent non-oily particulate matter and paraffin oil to represent oily particulate matter to test the protective ability of a professional mask product. The particle size used in these test standards is less than 2.5 microns and is therefore considered to be protective against PM2.5.
▲ China GB2626-2006 standard
FFP1. This is the European standard and is certified by the Comité Européen de Normalisation (CEN) respiratory protection equipment. The standard is to divide the particulate protective filter into two types: solid particle protection and liquid particle protection, which are tested and classified by NaCL (sodium chloride) and DOP (paraffin oil) aerosols respectively.
▲ European EN standard
NO.8
How to choose a mask?
A: The phrase “There is no best, only the most suitable” is the mask. In addition to the above mentioned points, in order to meet certain standards, we believe that fit and comfort are also important considerations.
“Efficient fit” is a prerequisite for all dust masks to work. The air is like a stream of water, where it flows first where resistance is small. A mask that does not form an effective confined space on your face is uncomfortable and has no effect.
If a mask leaks, it is really not as good as a dog, no, it is better not to wear it.
The other one is comfort. A mask is good to wear, Le Bleu does not press the nose, whether the breath is smooth, there is no taste, etc., we must consider the choice of masks.
Before we bought 15 anti-mite masks for a detailed evaluation of comfort, interested can drop down to the final recommended reading, the first one is oh.
NO.9
What are the small details to pay attention to when wearing/protecting masks?
A: In the process of purchasing and using, you need to pay attention to these points:
It is best to buy a single individually packaged mask (see the next question for reasons).
A head-mounted or neck-worn mask will have a higher fit than an ear-worn fit.
A mask with a skeleton will not cause a mask to contract with the breath during vigorous and rapid breathing, and the comfort of breathing will increase.
The mask that has just opened the bag will be somewhat tasteful. You can open the package in advance, or take out the mask and open it.
Disposable protective masks are not washable. Do not modify the mask yourself.
Mask replacement time varies from person to person, the surrounding environment, the time spent on the road, the way of wearing, and the frequency of use will have an impact. There are no strict life regulations for everyday applications (usually 3-4 days). However, when the protective mask is damaged, dirty or the breathing resistance is too large, the mask should be replaced in time.
If the glasses don’t fog, make the sealed nose clips fit the nose as much as possible.
Long-haired girls can wear a high ponytail or a large ball when wearing a head-mounted mask, so that the upper rope can be fixed at a higher position, which can improve the fit and comfort.
Some special people, such as children and the elderly, should wear masks carefully.
NO.10
How to use the used anti-mite mask?
A: It is recommended to put it in its original packaging bag.
After the mask is unpacked, we always habitually throw away the bag. In fact, this bag is a tool for storing the used anti-smashing mask.
Many of the better-designed tamper masks are now individually packaged, and a better mask package uses a zippered self-sealing port. Do not throw the bag after unpacking. The anti-smash mask is not required to be put back, and the plastic seal can be sealed to effectively avoid contact with external pollutants.
However, it should be noted that the anti-mite mask has just been taken off, it is best to cool it a little and dry it, and then put it in, to avoid the residual temperature in the bag to generate steam, breeding bacteria.
NO.11
Is the breathing valve on the tamper mask really useful?
A: It is really useful.
Most breathing valves are one-way valves. When inhaling, the breathing valve is closed and gas is passed through the mask fabric into the interior. When exhaling, the gas can be quickly discharged to avoid the feeling of tightness.
If there is no breathing valve, the hot and humid air tends to accumulate inside the mask, causing discomfort, which can cause dizziness due to lack of oxygen. Therefore, the price of a mask with a breathing valve will be relatively expensive.
NO.12
Is the electric tamper mask a gimmick or is it really practical?
A: The gimmick does not work, and it does.
Everyone knows from the above questions. As long as the mask meets the standard and the fit is good, it can better prevent sputum, and this electric smash-proof mask has taken a new step in comfort. This kind of mask can actively deliver air, not boring, and is more suitable for running and riding.
Electric tamper masks are also known as fresh air masks and are currently available in two types.
One is piped. It is pumped into the outside air through a small new fan attached to the arm. After being cleaned by a new fan, it is piped to the mask for breathing.
The downside is that it’s a bit ugly. The big pipe is connected to the mask and the new fan. It is especially like someone who runs out of the hospital intensive care unit.
The other is non-pipelined. The new fan is integrated into the mask, and the value of the fan is greatly improved. The disadvantage is that the volume is large and has a certain weight. The new fan is closer to the ear and has some noise.
Nothing else, as long as you don’t care about other people’s eyes, even if you wear it.
Finally, remind everyone again that if the local area is also affected by smog or dust, it is best to bring the mask. We also welcome everyone to share the air conditions in their respective locations in the message area, so that we envy envy.
