Criteria For A Good Air Purifier

Criteria For A Good Air Purifier

Air purifiers are widely used in the home, medical and industrial fields. In the home field, single household air purifiers are the mainstream products in the market. The main function is to remove particles in the air and sterilize, but also to solve the indoor, underground space, interior volatile organic matter air pollution problems caused by decoration or other reasons. Since the release of air pollutants in relatively enclosed Spaces is characterized by persistence and uncertainty, the use of air purifiers to purify indoor air is one of the internationally recognized methods to improve indoor air quality.

When buying an air purifier, consider:
First, the performance of the air purifier mainly depends on the output ratio of clean air. The higher the output ratio of clean air, the higher the efficiency of the purifier.
In order to make the indoor air quality reach a certain clean standard, the air purifier has two necessary hard indicators: 1. It is necessary to ensure that the indoor air reaches the international ventilation times (international 5 times); 2. The first cleaning efficiency of air purifier must be high. If indoor pollution sources are constantly emerging, these two hard indicators of air purifiers can keep indoor pollutants at low concentrations.
2. The efficiency of clean air purifier must be relatively high. The higher the purification efficiency (CADR), the better the air purifier
Purification efficiency (CADR) value has three indicators:
1. Solid particles, also known as dust, are usually simulated by cigarettes in China, so they are also known as smoke
2. Volatile Organic compounds (VOC), usually tested with toluene
3. Formaldehyde (formaldehyde)
Because the widely used air purifier has a very obvious dust removal effect, while the effect of volatile organic compounds and formaldehyde is not as good as that of dust, many businesses only indicate the CADR of dust.
preventive measure
First, is it absolutely secure?
To buy an air purifier, you just want to use it to get healthy, fresh air. Whether the air purifier is safe is the basic premise to judge whether it is desirable. Air purifier shell, movement and purification technology will directly affect the safety of air purifier. The purification technology should be the same as the positive and negative ions in nature, and 13 international organizations have certified the safety of ion purification technology.
Secondly, whether there is a scientific purification principle, to achieve efficient air purification effect.
International air purification has five principles, physical, electrostatic, chemical, negative ions, composite. In general, physical purification is the most commonly used and effective method. For example, dust, pollen, allergens, viruses and other large particles can be physically purified and filtered through HEPA technology; Benzene, toluene, formaldehyde and other harmful substances, in the physical purification method, activated carbon can be adsorbed. Purification.
According to the purification mode, from the active direction, purification mode is divided from the active direction, there are active purification mode (air purification), passive purification mode (fixed point purification) and active purification mode three. Passive compound purification. Passive purification only plays a role in purifying the inhaled air; Active purification method will produce purification effect on the whole space. Active and passive composite purification is the combination of the two, the effect is better.
Active purification is a controversial technique in the world. Since the concentration of pollutants in the air is generally below one percent, and active decontamination requires spraying higher concentrations of chemicals into the air, the air pollution level can even increase overall. For example, European and American countries prohibit the release of ozone into the air.
Third, whether specific purification needs are met.
As far as air purifiers are concerned, the purification function is the most concerned function. If your requirements for indoor air purifiers are only to improve indoor air quality, you can choose pure clean air with high cost performance.
With people's increasingly high requirements for the quality of life, the demand for air purifiers is no longer simply to purify indoor air. For example, people who work in closed air-conditioned rooms, because of the dehumidification effect of air conditioning, the air in the room becomes very dry and the skin becomes dry. Therefore, when choosing an air purifier, skin features will be purchased. Humidifier air purifier.
For people who are in the crowd for a long time and have larger indoor pollution, they need to breathe fresh air without bacteria. When choosing an air purifier, they will prefer one that is suitable for desktop use.
And people who own their own cars should choose car air purifiers to clean up all kinds of car odor, and even alleviate fatigue.
Four, combined with marketing and third party authoritative certification purchase.

Widely used air purifiers usually have the ability to kill bacteria and remove odors. When choosing an air purifier, we must pay special attention to whether its bactericidal power and odor control ability are indisputable. Generally speaking, sales volume is an important market test index.
