Function of air purifier
Air purifiers, also known as "air purifiers", air fresheners and purifiers, refer to products that can adsorb, decompose or transform various air pollutants (generally including decoration pollution such as PM2.5, dust, pollen, odor, formaldehyde, bacteria and allergens). ) and effectively improve air cleanliness, mainly divided into household, commercial, industrial and construction.
Suitable places and people for air purifiers
1. Renovation of old and new houses
After decoration pollution, there will be many harmful substances such as formaldehyde, benzene and xylene, which mainly exist in the adhesive of indoor wood-based panels. In addition, walls, wallpaper, cabinets will produce formaldehyde. Decoration pollutants have a great impact on health. Many reports show that volatile substances such as formaldehyde can cause childhood leukemia, acute aplastic anemia and other major diseases.
2. Smoking families and offices
According to relevant data, there are 1 1 100 million smokers in the world, among which China accounts for the highest proportion. There are 350 million smokers in the world, accounting for a quarter of the world's smokers, which also means that the proportion of local smokers in China has occupied one fifth of the country. In addition to first-hand smokers, there are a large number of second-hand smokers, and the health of second-hand smokers is more affected. Cigarettes contain more than 3,800 known chemicals, including carbon monoxide and nicotine.
3. People who are allergic to pollen and dust
Everyone's physique is different. Many people are allergic to pollen. People allergic to pollen often sneeze and have a runny nose. These symptoms will seriously affect their life and health, leading to bronchitis, rhinitis, asthma and so on. In the long run. Such groups need air purifiers more.
4. People with respiratory diseases
In China, there are as many as 300 million rhinitis patients, and it is difficult to cure rhinitis patients or other chronic respiratory diseases. Patients with severe rhinitis often have symptoms such as sneezing, runny nose, dizziness and brain swelling, which seriously affect their work and life. The recurrence of rhinitis is actually closely related to indoor allergens, so ensuring a healthy indoor environment plays an important role in relieving rhinitis.
What kind of air purifier is suitable for home use and has complete purification functions?
electrostatic precipitator
At present, some purifiers on the market adopt technologies such as static electricity and negative ions. Although they have the advantages of being quiet, saving electricity and not using consumables, consumers should be cautious when buying and using them. On the one hand, the use of this purifier is easy to produce secondary pollution such as ozone, which is not good for human health. On the other hand, even if the merchants report that the ozone and other substances produced by the products meet the national standards, they may only meet the standards in a short time, and pollutants will still accumulate after long-term continuous operation.
Filter air purifier
According to the recommendation of major network platforms and the sales of air purifiers, more consumers will choose mechanical filter air purifiers. Filtration and purification are pure physical filtration, which will not produce harmful gas and cause secondary pollution. According to relevant network data, according to the usage of users in various places, the use time of HEPA filter air purifier in most central cities in China is about 8 months to 12 months.
HEPA filter air purifier can effectively remove fine pollutants, bacteria, allergens and so on in the smog air.
To remove harmful chemical gases such as formaldehyde, benzene and tvoc, more air purifiers will be built with high-quality activated carbon, cold catalyst and cold catalyst. Coarse filter +HEPA+ activated carbon+cold catalyst/cold catalyst has almost become the standard of brand air purifiers. Although many merchants' in addition to formaldehyde technical names are high-tech and difficult to understand, they are all the same.

Origin: China, particle CADR:750? /h, particulate CCM: P4, formaldehyde CADR:244m? /h, formaldehyde CCM: F4, applicable area: about 50㎡.
Comments: The name 352 doesn't look like a brand name at first glance. In fact, 352 means three times five divided by two, which means that the speed of removing smog is fast, and the CADR value of particulate matter is as high as 750m? /h, which can ensure the rapid removal of smog when the smog is serious, and the purification efficiency far exceeds other products at the same price.
The roller is well made, basically silent and can be locked. The operation is convenient and simple, and the function is basically perfect.
For just need, the cost performance is high, but at this price, the purification speed and the service time of the filter element cannot be taken into account. If the smog is serious, the filter element needs to be replaced every 1-2 months.

Origin: Sweden, particle CADR:650? /h, particulate CCM: P3, formaldehyde CADR:280m? /h, formaldehyde CCM: F3, applicable area: about 60m2.
Comments: Bruyal Blueair is a relatively old-fashioned product in air purifiers. The publicity stunt is "purchasing by the US Embassy in China". Its formaldehyde CADR and particulate CCM are the highest level, and there are no obvious shortcomings in noise and energy efficiency. Suitable for rooms of 49-84 square meters. Not to mention the purification ability, of course, not to mention the price.
The product line is also very rich, such as Blueair 650E model suitable for large-scale use, and the CADR value of particulate matter is 830m? /h, the applicable area is about 55㎡.

Comments: IQAir has an ultra-high purification rate and almost abnormal filter life (its filter life supports 365 x 24 hours start-up, keeping the air clean at home at all times).
HEPA filter element of HealthPro 250 has passed the strict standard test of EU EN 1822 (grade H 12/H 13), which meets the medical standard. It can not only remove PM2.5, but also purify bacteria and viruses with an efficiency of not less than 99.97%. The most direct problem brought by luxury filter element is high power consumption. If calculated according to daily usage 14 hours, the product will consume 1 kwh in 1 5 days, while Amway Yixin, the most energy-saving product, will consume1kwh in nearly 8 days. Moreover, it does not support remote control, and it is impossible to monitor the air quality in the home in real time.

Origin: USA, particle CADR: 4.5 million? /h, particulate CCM: P2, formaldehyde CADR:67m? /h, formaldehyde CCM: F4, applicable area: about 50㎡.
Comments: Honeywell is an international company with a history of more than 100 years, 1996, and was rated as one of the 20 most respected high-tech enterprises by American Fortune magazine. Honeywell has always had a good reputation for quality, but the design is monotonous.
Honeywell occupies three of the six "recommended" air purifier models in the Consumer Report of the United States, which is enough to illustrate the strength of this brand.
In the comparative test released by Shanghai Consumer Protection Committee last year, the machine performed well in particulate matter purification, and the measured CADR value of particulate matter purification reached 477m? /h, but the use cost is high and the filter replacement cycle is frequent.

Origin: China, particle CADR:800 meters? /h, particulate CCM: P4, formaldehyde CADR:783m? /h, formaldehyde CCM: F4, applicable area: about 75m2.
Comments: When I saw the CADR value of Haier formaldehyde, I was shocked by this data. The unique "amino acid" technology of composite filter screen has a long-acting in addition to formaldehyde. This formaldehyde CADR is at least 95% ahead of the domestic machine, which means that its purification speed is fast enough, and high CADR is the first index to measure in addition to formaldehyde's ability. On the premise of high performance parameters, it is not easy to realize a small-scale model.
The top aromatherapy box can put a little dried flowers or essential oil according to your own preferences, which can purify the air and make the fragrance diffuse indoors.

Philips AC6608 air purifier has excellent performance in purification performance, service life and noise control with excellent double-sided air inlet design and the latest VitaShield filter. Of course, limited by brand positioning, product price and later use cost reduce the product cost performance.
9. panasonic air purifier F-73C6VJD
Origin: Japan, particle CADR:386m? /h, particulate CCM: P4, formaldehyde CADR: 19 1m? /h, formaldehyde CCM: F4, applicable area: about 35m2.

10. Xiaomi air purifier
Origin: China, particle CADR: 3 10m? /h, particulate CCM: P3, formaldehyde CADR:60m? /h, formaldehyde CCM: F3, applicable area: about 20m2.
Comments: The finale said that Xiaomi is the only one. Today's Xiaomi air purifier has come out to the second generation, and it can indeed be used as an entry-level choice. The H 1 1 filter which has been criticized by many people is still in use. The CADR value of particulate matter is 330m3/h, and the applicable area is about 20m2. Although there are in addition to formaldehyde and composite filter to choose from, the CADR value of formaldehyde is not marked.
In the purifier industry, the problem of "high noise" inevitably appears on Xiaomi air purifier 2, and the low particulate matter CADR in sleep mode limits the practical application experience of the product.
As far as the price of 799 is concerned, it is very close to people in the same industry. What kind of H 13 filter do you need? Of course, Xiaomi has many additional functions, although many people complain about the detection accuracy and automatic operation.
For ordinary consumers, the industry standard of air purification is obscure, and a large number of exclusive terms can't make everyone spend a lot of time when purchasing air purifiers. A good air purifier should have the characteristics of fast purification speed, low cost of replacing filter screen, energy saving, quiet and comfortable, especially noise pollution. Without offline experience, it is difficult to decide whether the working machine can meet your decibel requirements when sleeping.
