Because of the different user groups of air purifiers, there are different types and kinds of air purifiers on the market, and many consumers have some trouble choosing the right air purifier. Different groups of people and occasions have different requirements for air quality, and different types as well as degrees of air pollution have different requirements for air purifiers.
What parameters to look for in an air purifier
For solving the problem of indoor air pollution, there is no doubt about the use of air purifiers. Whether in the e-commerce platform or physical shops, air purifiers can be said to be a wide range of everything, so we should pay attention to what matters when buying. Choosing an air purifier, there is a saying in the industry that is by the principle of "three highs and one low", where "three highs and one low" refers to the four major parameters clearly stated in the national standard.
1. High CADR value
CADR is a direct indicator of purification efficiency, meaning "clean air output ratio". The unit is m³/h, the higher the CADR value, the more air is purified per unit of time, and the better the purification effect.
2. High CCM value
CCM is the cumulative purification volume. The unit is milligrams, which can be simply understood as the dust capacity of the filter.CCM can also be expressed as the degree of durability of the filter, i.e., the total amount of pollutants filtered during the entire life cycle of the filter. The higher the CCM value, the longer the life of the filter, and the better the filtration effect.
3. High purification efficiency
Purification energy efficiency is the ratio of CADR clean air volume to rated power. The amount of clean air produced by the air purifier in the rated state of the unit power consumption is divided into particulate purification energy efficiency and formaldehyde purification energy efficiency. For particulate purification energy efficiency value, 2 is the qualified level, and 5 is a high-efficiency level; for formaldehyde purification energy efficiency value, 0.5 is the qualified level, and 1 is a high-efficiency level.
4. Low noise value
The noise value of the air purifier is the amount of sound generated when the air purifier is used to reach the maximum CADR value. However, it should be noted that, in general, as the CADR value rises, the noise value of the machine will also increase accordingly.
How to buy an air purifier?
1. According to the type of air purifier
According to different working principles, air purifiers can be divided into passive adsorption air purifiers, active air purifiers, and dual air purifiers.
1.1 Passive adsorption air purifier
The main working principle is to use the role of the fan, the air will be pumped into the machine through the built-in filter to filter out dust, bacteria, and other pollutants in the air. The air purification effect of this type of purifier is usually determined by the type of fan and the quality and quantity of the filter.
1.2 Active Air Purifier
Instead of relying on the assistance of fans and filters, they take the initiative to strike at pollutants by releasing purifying and sterilizing factors to purify the air of pollutants, and then use air diffusion to purify all corners of the room without dead ends.
1.3 Dual air purifier
It is a combination of a passive adsorption air purifier and an active air purifier, which first uses the operating principle of a passive adsorption purifier to initially filter the airborne pollutants, and then uses the principle of an active air purifier to purify the remaining pollutants in the air again.
2. According to the air purifier function
Choose the desired function according to the air environment of the residence and the suitable purification effect. The functions of air purifiers are mainly purification, sterilization, filtration, humidification, etc. Different products will have a variety of functions.
2.1 Sterilising air purifier
Many people are allergic to mites and their excrement, which can lead to asthma and other breathing problems. The de-mite function reduces the presence of allergens by using UV lamps or electronic sterilizers to kill airborne mites and bacteria. This feature is particularly suitable for bedrooms and children's rooms to provide a clean sleeping environment for allergy sufferers.
2.2 Negative Ion Air Purifier
Negative ions are small negatively charged particles that bind with positive ions and particulate matter in the air, thus causing them to settle to the ground. This feature can help purify the air of particles such as bacteria, viruses, and dust, and eliminate odors. In addition, negative ions can improve one's sleep quality, enhance concentration, and strengthen the immune system.
2.3 Deformaldehyde Air Purifier
Suitable for newly renovated indoor environment. Main hazards: Formaldehyde is a protoplasmic poison that can combine with proteins. After inhaling high concentrations of formaldehyde, there will be severe irritation and edema of the respiratory tract, eye-stinging, headache, and bronchial asthma can also occur. Particulate matter with a particle size of 3.5 microns or less can be inhaled into the human bronchial tubes and alveoli and deposited, causing or aggravating respiratory diseases.
2.4 Smoke and Dust Air Purifiers
High-efficiency filters in air purifiers can effectively remove smoke and dust from the room. The smoke removal function is particularly important among smokers. In addition, the dust removal function of air purifiers can also help eliminate indoor allergens such as pollen, bacteria, and viruses.
3. According to air purifier styles
3.1 Desktop Air Purifier
Desktop-style air purifiers are small and portable air purification devices that are suitable for use in small spaces such as offices, study rooms, and bedrooms. This type of air purifier generally adopts high-efficiency filtration technology, which can remove tiny particles, bacteria, viruses, and other harmful substances in indoor air, and at the same time, it has the advantages of silence and energy saving.
3.2 Floor-standing air purifier
Floor-standing air purifiers are suitable for larger indoor spaces, such as living rooms, bedrooms, conference rooms, etc. Compared with desktop air purifiers, floor-standing air purifiers are more powerful, can cover a larger area, and at the same time have more functions and features.
3.3 Humidifying Air Purifier
If you are located in a dry area, often turn on the air conditioner to be dehumidified by the air conditioner and cause dry indoor air, or have high requirements for air quality, then buying an air purifier with humidification function will be the most suitable choice.
3.4 Intelligent Air Purifier
If you like automated operation, intelligent monitoring of air quality, or to reflect noble taste, or for gifts that need to be more decent, then buying a smart air purifier is the best choice.
4. According to the space to choose an air purifier
Air purifiers are used on different occasions to provide a fresh and clean air environment. According to the different occasions, the design and functions of air purifiers are also different. The following is a detailed description of air purifiers for four occasions: in-vehicle, bedroom, living room, and office.
4.1 In-vehicle air purifiers
As the popularity of automobiles increases, people's demand for in-vehicle air quality is also increasing, and the demand for in-vehicle purifiers has increased accordingly. Car air purifiers are usually of a small design and can be easily installed inside the car, such as hanging from the rear-view mirror or placed under the seat.
4.2 Office Air Purifiers
In offices, air quality is often poor due to the high density of people, the use of office equipment, and pollution from the external environment. Therefore, it is very important to choose an air purifier that is suitable for office use. Maigoo recommends choosing an air purifier with high-efficiency filtration, activated carbon adsorption, and ozone removal to keep the air fresh and pleasant.
4.3 Bedroom Air Purifier
The bedroom is the place where we rest and sleep, keeping the air in the bedroom fresh and clean is crucial for our health. Bedroom air purifiers are usually designed to be silent so as not to disturb our sleep. They also have a highly efficient filtration system that removes bacteria, viruses, dust, pollen, and other airborne pollutants to purify the air and provide a fresh sleeping environment.
4.4 Living Room Air Purifier
The living room is a place for family activities and entertaining guests and therefore has high air quality requirements. Living room air purifiers usually have a large handling capacity and can effectively handle a larger range of space. They generally have a multi-layer filtration system that removes fine particles, smoke, odors, and other pollutants, keeping the air in the living room fresh and clean, and providing a healthy and pleasant environment for family members and guests.
5. According to the crowd choose an air purifier
Air purifier is a product that can effectively improve the cleanliness of the air, and can adsorb, transform or decompose pollutants in the air. How to choose an air purifier for different groups of people?
5.1 Pregnant women
Pregnant women are people who are more susceptible to external adverse factors and have extremely high requirements for air quality. If they are exposed to toxic and harmful gases for a long time, it will cause irreversible damage to their bodies. For example, formaldehyde has reproductive toxicity, which will affect female pregnancy and may have an impact on the reproductive development and chromosomes of the fetus. And in some public places or confined spaces, pregnant women are also susceptible to the effects of second-hand smoke. It is recommended to install air purifiers to remove formaldehyde and smoke.
5.2 The Elderly
Elderly people usually have more health problems, such as COPD, heart disease, diabetes, etc., and have higher requirements for air quality. Therefore, the elderly should choose an air purifier that can efficiently remove PM2.5, formaldehyde, bacteria, and viruses.
5.3 Children
Children are in the stage of growth and development, their lungs are immature and their immune system is relatively fragile, so they need to pay special attention to the impact of harmful substances in the air on them. When choosing an air purifier, children's families should select a product that is quiet, safe, and reliable to avoid ear-splitting noises that may affect their children and pay attention to whether the product has passed the children's toy level safety certification.
5.4 Allergy-prone people
For allergens such as pollen, pet hair, and other sensitive substances, they need to choose air purifiers that can filter tiny particles, such as products with an activated carbon filter layer, and HEPA filters that can filter pollen and other allergens. In addition, allergy-prone people need to pay attention to the CADR (Clean Air Delivery Rate) of the air purifier to ensure that it can effectively clean the air in a shorter period.
6. According to the price to choose an air purifier
Price is also a factor we need to consider. The price of air purifiers on the market varies greatly, and the higher the price, the better the function and filtration effect will be accordingly. Therefore, we need to consider our own needs when choosing a product, weighing the price and cost-effectiveness.

7. According to the size of the house choose an air purifier
The cleaning ability of the air purifier should be selected according to the room area, generally speaking, the stronger the cleaning ability of the product is suitable for a large area of the room, and the cleaning ability of the lower product is suitable for a small area of the room. Therefore, when choosing a Jinhua apparatus, it is recommended to choose the appropriate purification rate according to the area of your house.
7.1 Below 30 square metres
For rooms under 30 square meters, it is sufficient to choose an air purifier with a CADR value of around 200 cubic meters per hour. The CADR value refers to the amount of air that the purifier can process per hour, and the higher the value, the stronger the performance of the purifier. It is also important to pay attention to the noise level of the air purifier. Generally speaking, the noise level should not exceed 70 decibels, otherwise it will disturb people's normal rest.
7.2 Between 30-50 square meters
For rooms between 30-50 square meters, you can choose an air purifier with a CADR value of 250-300 cubic meters per hour. This range of CADR value can meet the needs of larger spaces, and you also need to pay attention to the air purifier's filter life and energy efficiency ratio and other parameters. Generally speaking, the longer the filter life and the higher the energy efficiency ratio, the better the air purifier will perform.
7.3 Between 50-100 square metres
For rooms between 50-100 square meters, you need to choose an air purifier with a CADR value of 300-400 cubic meters per hour. This range of CADR values will allow for a larger space, while the noise issue and placement of the air purifier also need to be considered. Generally speaking, the noise level of an air purifier should not exceed 70 decibels, and it needs to be placed in the center of the room to ensure purification.
7.4 Above 100 square metres
For rooms over 100 square meters, an air purifier with a CADR of 400 cubic meters per hour or more needs to be selected. You also need to consider the type of filter and filtration effect of the air purifier, etc. Maigoo suggests that if you want a better purification effect, you can choose a commercial air purifier with a large purification area, which has a larger purification area compared to the home office and a stronger purification capacity.
Notes on the use of air purifiers
1, timely replacement of the filter material: in the process of using the air purifier should pay attention to observe the purification effect, if you find that the purification effect is significantly reduced or turn on the purifier after the smell, you must promptly replace the filter material and clean the filter.
2, pay attention to the secondary pollution: with the use of air purifiers, various types of pollutants in the purifier enrichment, these pollutants may be released by the air purifier again, the formation of secondary pollution. In addition, the use of electrostatic dust removal and simple negative ion technology air purifier will produce ozone, a certain amount of ozone can kill bacteria, viruses, and decomposition of gaseous pollutants, but excessive ozone is harmful to the body, resulting in inflammation of the upper respiratory tract, asthma and other respiratory diseases.
3, the use of air purifiers in newly renovated houses: the formaldehyde contained in the decoration materials or furniture has a slow release process, even if the use of air purifiers, should still pay attention to frequent ventilation.
4, timely opening of windows for ventilation: when pollutants mainly originate from outdoors, such as heavy haze weather, should reduce the frequency of window opening to reduce the introduction of new pollutants from outdoors. However, the air purifier itself does not have the function of oxygen production, long-term use in a confined space will lead to increased indoor carbon dioxide content and air freshness, so it is necessary to combine it with the actual use of the situation of the timely opening of windows and ventilation.
