The 15 Best Air Purifiers for Home in 2021. Which brand of air purifier is better? Can air purifiers remove formaldehyde?
Before I used an air purifier, I never felt how dirty the air at home was. I used to use a lot of tissues every day because of rhinitis. I tried Western medicine, but the result was still useless.
After using an air purifier, I know what is real fresh air! As an important household appliance directly related to the breathing of the family, the purchase of air purifiers cannot be pitted. As for how to purchase an air purifier, it is very important homework.
Therefore, taking advantage of my free time, I sorted out the key points for purchasing a 6000-word ultra-full air purifier, and attached recommendations for the best air purifiers for homes with high comprehensive performance!
The 15 Best Air Purifiers for Home in 2021
1. What is an air purifier?
Air purifiers, also known as "air cleaners", air cleaners, and purifiers, refer to decoration pollution that can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, peculiar smell, formaldehyde, etc.), Bacteria, allergens, etc.), products that effectively improve air cleanliness, can be used in family residences, commercial residences, industrial areas, and so on.
2. The principle of air purifier
The components of the air purifier include fans, motors, fans, air filters, and other systems. The working procedure of an air purifier can basically be understood as: the motor and the fan in the machine make the indoor air circulate, and the polluted air passes through the machine. The air filter will remove or adsorb various pollutants.
Some air purifiers will also install a negative ion generator at the air outlet. When working, the high voltage in the negative ion generator generates DC negative high voltage, which continuously ionizes the air to produce a large number of negative ions, which are sent out by the micro fan to form a negative ion airflow to achieve cleanliness The purpose of purifying the air. To put it simply, the polluted air is sucked in, then passed through the filter system in the purifier to purify the air with high power, and then discharged. This is a repeated process, so when using the air purifier, pay attention to whether it can be put in the room. Everywhere in the world is purified.
On the other hand, the working principle of air purifiers can also be divided into active and passive filtration and double purification (active + passive).
Principle of Active Purification
It does not need to rely on systems such as fans and filters to passively wait for the air to be sucked in and then purify the air. By taking advantage of the characteristics of air diffusion, fresh air can be slowly delivered to the room to fill the entire room. The active air purifier has no filter.
Passive purification principle
It is to release fresh air into the air after it is inhaled and filtered. The disadvantage of the passive principle is that it is difficult to purify every corner of the house, while active purification can.
The dual purification principle combines the advantages of the active and passive principles, has double guarantees, and can effectively purify air quality in a large area.
3. The applicable scenarios/crowd of air purifiers
Although working in an office for a long time does not seem to be hard, everyone has been breathing the same piece of air in a confined space. Over time, the air quality will become turbid, which can easily lead to dizziness, chest tightness, fatigue, emotional ups and downs, and other discomfort symptoms. It affects work efficiency, causes various diseases, and can cause cancer in severe cases.
I believe that social animals will understand how deadly it is to open windows for ventilation in cold weather, and there is also a need to turn on air-conditioning in hot weather. Therefore, air purifiers are perfect for offices. It is strongly recommended that bosses arrange air purification for employees in their offices. Device.
2. At home
It is absolutely necessary to buy an air purifier at home! The air and dust on the road outside cannot be controlled, but we still have the right to choose at home. If we buy an air purifier at home, we can enjoy the fresh air at home. Dust, PM2.5, harmful gases, etc., are all absorbed to keep the home fresh for a long time, especially if the home has just been renovated or moved into a new home, such as some residual formaldehyde and harmful gases after renovation. The air purifier can be done easily.
3. In the car
Although this is a relatively small space, it is actually necessary for people who need to use a car for a long time and stay in the car.
Because the car is also a small confined space, for people who are professional drivers or Didi drivers, driving in this environment will be prone to fatigue and sleepiness. Although opening windows can solve this problem, the frequency of opening windows is too high. When it is high, there will be dust all over the car, which will only increase worry. Putting a small air purifier in the car can not only suck dust but also freshen the air and increase the humidity in the air appropriately, which is good for the family and yourself.
4. Pregnant women
Pregnant women will feel general malaise in a room with severe air pollution, such as dizziness, sweating, dry tongue, chest tightness, vomiting, and other symptoms, which adversely affect the development of the fetus. The risk of developing heart disease is three times higher than that of a child born to a pregnant woman who breathes fresh air. Therefore, if you have a pregnant woman at home, it is best to buy an air purifier to benefit the physical and mental health of the pregnant woman and her fetus.
Children’s bodies are relatively fragile, and when they are growing up, their immune systems are relatively fragile and vulnerable to indoor air pollution, leading to reduced immunity, delayed physical development, and blood diseases. Severely polluted air can also easily increase the incidence of childhood asthma and greatly reduce children's intelligence.
The physical function of the elderly declines and many chronic diseases are often plagued by them. Air pollution not only causes respiratory diseases such as bronchitis, pharyngitis, and pneumonia in the elderly. It can also induce high blood pressure, heart disease, cerebral hemorrhage, and other cardiovascular diseases.
7. People with rhinitis/allergy
Dust, fine hair, and invisible things in the air are all enemies of people with allergies. People who are prone to allergies must buy an air purifier at home. Breathing for a long time and being in a fresh air environment is not only good for allergies, but also for the treatment of allergies. Maybe the purifier can also purify allergens by the way. In addition, patients with rhinitis, like this kind of respiratory disease, really need pure and fresh air.
8. Keep pets
Now more and more people have become a cat/dog family. Multiple pets can make life more welcoming, but the problem of pet hair loss is that every owner has a particular headache, and cats, dogs, and dogs are not like people every day. They can take a bath, and the animals will still carry some small bacteria. An air purifier in the home can remove some bacteria and hair or harmful substances left by animals.
9. Someone smokes at home
I really have a say in this. Because the elders in the family smoke, I personally can't stand the smell of cigarettes, and it is choking and uncomfortable. Long-term expectation is also easy to cause the incidence of many diseases in a second-hand smoke environment, and air purifiers can effectively reduce this hazard.
Air purifiers are so useful and applicable to such a wide range of scenarios. So what should I pay attention to when buying an air purifier? Let's introduce it in detail below.
4. What should I pay attention to when purchasing an air purifier?
This point is aimed at air purifiers with passive purification principles. The filter in the air purifier is the most important part of the purification process.
The filter in the air purifier can be divided into deodorizing filter, formaldehyde removal filter, dust collecting filter, HEPA filter, etc. according to different functions.
- The deodorizing filter is mainly used to filter smelly and harmful gases, and the formaldehyde removal filter can remove formaldehyde.
- The dust collection filter mainly absorbs dust and particles with larger diameters.
- The HEPA filter can effectively remove particulate matter and filter various harmful gases to achieve the best air purification effect.
Therefore, if an air purifier can have different filters, it is a plus for the purification effect. The more layers, the higher the purification level.
2. CADR value (clean air volume)
The CADR value is the final purified air output value within a certain applicable area. Simply put, it is the amount of air purified per hour, in cubic meters per hour.
The air purifiers that are officially sold on the market will be marked with CADR value parameters, CADR value = applicable area / 0.12 (0.12 is the conversion factor of the national standard).
Therefore, when buying an air purifier, make sure that the area of use in your home is sufficient to be completely purified. For example, a 40-square-meter living room or bedroom requires a CADR value of 480 cubic meters per hour. In general, the larger the CADR value, the larger the area and air volume to be purified.
3. CCM value (cumulative purification capacity)
The new national standard defines CCM as the total weight of accumulated pollutants when the CDR value drops to 50%, which specifically represents the continuous purification capacity of the air purifier. The higher the value, the use of air purifier filter consumables. The longer the life span.
The CCM value is represented by P, the unit is mg. CCM particulate matter is divided into four levels P1-P4, and CCM formaldehyde is divided into four levels F1-F4. The higher the level, the greater the weight of the purified particulate matter.
Therefore, only a high CADR does not mean that the air purifier is effective. Only when the CCM is also high can it prove that this air purifier not only has a faster purification efficiency but also has a strong purification capacity and a longer filter life.
4. Purification energy efficiency
Purification energy efficiency means that the standard stipulates the energy efficiency limit value, energy efficiency grade, test, and calculation method of air purifiers. It is suitable for the rated voltage not exceeding 250V and has a certain particulate matter purification capability (the particulate matter clean air volume is 50m 3 /h ~ 800m3 /h) Air purifier.
The limit value of the air purifier refers to the lowest value of the energy efficiency ratio and the maximum value of standby filtration that can be achieved under certain conditions.
Therefore, the energy efficiency level of space purification is divided into three levels, the first level is the highest, followed by the second level, and the third level is the lowest. When choosing an air purifier, you can choose high-efficiency purification.
The above four factors are all necessary factors in the professional field. When choosing products, most consumers tend to ignore the noise factor, but noise is also one of the core indicators in the national standard.
In the new national standard, the working noise of the air purifier must not be greater than 70 decibels. Although 70 decibels is the standard of the new national standard, the lower the noise decibels during sleep, the better, preferably less than 35 decibels.
When the air purifier needs to be used in the bedroom, low noise becomes a key advantage. Try to choose an air purifier with low noise decibels for yourself to make your home life more comfortable.
No matter what type of product you choose, choosing a good brand is equivalent to taking 70% fewer detours. A good brand will not only provide considerate pre-sales service to help you understand the various parameters of the product, but also provide meticulous after-sales service, double guarantee, and double peace of mind. Brands that have done better in the field of air purifiers include Philips, Xiaomi, IAM, Panasonic, Midea, Haier, and so on.
5. Some misunderstandings about air purifiers
1. Air purifiers are not the most effective way to remove formaldehyde
Formaldehyde is a very harmful gas. Although air purifiers can remove formaldehyde to a certain extent, if you want to quickly remove the smell of formaldehyde in your home, the best thing to do is to maintain a well-ventilated and ventilated home environment. Many businesses are eager for quick success. In order to sell products quickly, they will exaggerate the effects of the products. Consumers are generally simple and easy to be fooled. Therefore, if you want to remove formaldehyde, do not use only air purifiers or buy them lightly. Products of similar businesses.
2. Don't rely too much on air purifiers
The past 2020 was a special year. I believe everyone has paid more attention to hygiene and safety. Although air purifiers can achieve the purpose of disinfection and sterilization, you should pay attention to your own disinfection and hygiene when returning from outside, and The home environment should be kept clean. You can't think that it is omnipotent just because you have an air purifier in your home. Most of the environment is human intervention, and you should rely more on your own actions and pay attention to personal hygiene.
3. You can suspend use when the air in your home is too humid
When the air humidity in the home is too high, you can suspend the use of the air purifier, because too humid air can easily damage the machine, and the purified air will still have a not very fresh smell, especially in southern families, which requires more attention. at this point.

11. Molekule Air Large Room Air Purifier with PECO Technology for Allergens
If you suffer from allergies, you'll be happy to see our top pick for the best air purifiers for allergies. The Molekule Air Purifier features one of the most unique filtration methods on the market today. Rather than capturing contaminants in a filter, the Molekule actually breaks down the particles at the molecular level.
The patented Photoelectrochemical Oxidation (PECO) filter is the key to the process. PECO is light-activated nanotechnology. After the air passes through a pre-filter to remove the larger particles, it enters the PECO filter where the nanoparticles bind to the particles in the air. When light hits these newly attached contaminants, they break down at the molecular level and become essentially harmless.
This is very good news for allergy sufferers because it means that pollutants are not stored in a filter where they can still be reintroduced into the environment. Additionally, this filtration technique can collect particles 1,000 times smaller than the standard HEPA filter, making it one of the most efficient filtration systems available.

FAQ About Best Air Purifiers for Home
1. Are our household air purifiers useful?
The answer is somewhat useful, but if the home is seriously polluted, the air purifier alone cannot improve the indoor air in the home.
The principle of the purifier to treat formaldehyde is activated carbon adsorption. The advantage of stacking a few bags of activated carbon in the house is that with active air circulation, the adsorption effect will be better.
Activated carbon adsorption, according to the different iodine value of different materials, the amount of formaldehyde that can be adsorbed is different, but all have a life, and it can be said that life is very short. It can be seen that how much formaldehyde can be absorbed, and more importantly, depends on the weight of activated carbon!
And this is the link that purifier propaganda has been deliberately concealing.
There is no doubt that the purifier equipped with an activated carbon filter has the ability to remove formaldehyde, and the test report can also verify this. However, please pay attention to the environment in which the test report is used.
If your house has just been renovated, using a purifier to remove formaldehyde will definitely be useful in the first week, but the effect will get worse after that. If you want to move in quickly, you can also use technology products such as Shenguang Aldase to remove formaldehyde.
2. What is the function of the air purifier?
Most air purifiers extract a certain volume of polluted air through the motor in the equipment and release clean air after layer-by-layer filtration, thereby reducing indoor pollutants, improving air quality, and deodorizing. If the decoration owner wants to remove the formaldehyde after the decoration, and the user wants to absorb the smog and bacteria in the room, it can be done through an air purifier. Of course, the actual process will be much more complicated than we thought, so I won't repeat it here.
At present, there is no direct evidence to prove that household air purifiers can adsorb or kill the new coronavirus. However, according to the analysis of its principles, even in the home or office, even ordinary functional air purifiers have a certain effect on improving indoor air quality and reducing the risk of infection. However, in the face of the new type of coronavirus, air purifiers cannot completely absorb and kill the new type of coronavirus.
3. How to make the air purifier have a better purification effect
Some studies believe that harmful substances such as bacteria and viruses in indoor air often cannot exist alone. They are usually spread on suspended particles in the air in the form of droplets and aerosols. The main function of air purifiers is to remove this air. The suspended particles in the air are effectively blocked to achieve the purpose of purifying the air. For consumers, who want the air purifier at home to better purify the indoor air, it is recommended that you pay attention to the following three points when using it.
a. Which placed in the correct position
The position of the purifier is very particular. If conditions permit, it is best to place it in the center of the room, especially not to place the purifier against the wall. This will greatly reduce the purification effect, such as it must be against the wall. When placed, it is necessary to leave a certain distance from the wall to ensure smooth air in and out of the machine and help indoor air circulation.
Do not put the air purifier and the water container together, or put it together with the humidifier, to prevent water vapor from entering the air purifier, causing damage to the machine, or electric shock.
b. Open windows for ventilation at the right time
In fact, the air purifier must be carried out in a relatively closed space during normal operation. At this time, opening doors and windows will increase the working pressure of the air purifier and reduce the purification effect. The user can open the windows for ventilation when going out or properly ventilate when the outdoor air is good.
c. Plug and unplug the power supply correctly
If we do not use the air purifier for a long time, we must unplug the power supply. When unplugging the power supply, we must hold the plug. Do not pull the power cord to unplug the plug. Otherwise, it is easy to cause power damage or electric shock.
Conclusion of The 15 Best Air Purifiers for Your Home in 2021
After reading the detailed introduction of the above air purifiers, I believe that everyone has a new understanding of air purifiers. The era of focusing on environmental protection and health has come, so hurry up and start one!
A lot has been said about air purifiers. The specific buying principle is actually to buy the most suitable one within your budget. If it’s a bedroom, in order to avoid overperformance and save costs, you can choose a small space within your budget. If it’s a whole house purification, then the flagship large model will be A better choice.
Of course, on the whole, it is better to buy brands with better quality, better reputation, and higher technical content. After all, clean and fresh air is more worthwhile.
