Function of air purifier
Air purifiers are mainly used to solve indoor air problems caused by decoration or other reasons. Because indoor air pollution has persistent and uncertain factors. The use of air purifiers can maintain a healthy and environmentally friendly home environment.
Applicable place: newly renovated residence; There are homes for the elderly, children, pregnant women and newborns; The residence of patients with asthma, allergic rhinitis and pollen allergy; Houses for keeping pets and livestock; Houses affected by secondhand smoke; Hotels and public places; A place with a high infection rate.
What is the principle of air purifier?
The main principle of an air purifier is a device that separates and removes one or more pollutants from the air. Air molecules are separated by photochemistry, photoplasma and photoionization, and then bacteria in the air and some pathogens caused by dead dander and pollen are removed by photocatalysis, deep ultraviolet light and active oxygen (ozone O3).
Is the air purifier useful?
Although air purifiers are powerful, not all air purifiers are easy to use. Generally speaking, the purification effect of a good air purifier will be better, and the purification effect of an inferior air purifier will not be achieved at all.
Good air purifier standard: to ensure that the indoor air reaches a certain number of air changes; The primary purification efficiency of air purifier must be relatively high, and the absorption effect of dust, volatile organic compounds and formaldehyde is a good criterion for air purifier.
Buy an air purifier
1. See purification methods: There are several purification methods, such as RGF PHI purification system, chemical reagents, ultraviolet germicidal lamp, ozone generator, electrostatic dust filter, high-efficiency catalytic activated carbon, photocatalyst, etc. Although each has its own advantages, in general, RGF PHI purification system is the best.
2. Look at the purification technology: At present, there are three kinds of filtration technologies for purifiers: HEPA filtration technology, ion wind technology and low-temperature asymmetric plasma air purification technology, each with its own advantages, but generally speaking, low-temperature asymmetric plasma air purification technology is better.
3. Look at the filter screen and air purification efficiency: these two indicators can reflect the quality of the air purifier.
4. Look at the humidification method: It is also important to keep the air humidity when purifying the air. A good humidification method can keep the air unobstructed.
Therefore, the most important thing to buy an air purifier is to look at the product quality. Products with good quality will have better efficiency and effect.

What is an air purifier?
Air purifiers, also known as "air purifiers" and air fresheners, refer to products that can adsorb, decompose or transform various air pollutants (generally including dust, pollen, odor and decoration pollution such as formaldehyde, bacteria and allergens). ) and effectively improve air cleanliness. At present, domestic and commercial air purifiers are mainly used to remove indoor air pollution.
Matters needing attention in purchasing air purifier.
Whether it has a scientific purification principle and achieves an efficient air purifier effect.
There are five principles of air purification in the world: physics, static electricity, chemistry, negative ions and compound. Generally speaking, physical purification is the most commonly used and effective method. For example, dust, pollen, allergic substances, viruses and other large particles can be filtered by HEPA technology in physical purification; The odor of harmful substances such as benzene, toluene and formaldehyde can be purified by activated carbon adsorption in physical purification.
According to the purification mode, it can be divided into active direction, active purification mode (air purification), passive purification mode (fixed-point purification) and active-passive compound purification. Passive purification can only purify the inhaled air; Active purification will purify the whole space. Active and passive compound purification is a combination of the two, and the effect is better.
Active purification is a controversial technology in the world. Because the concentration of pollutants in the air is generally 1/100,000 or even lower, and active purification requires spraying higher concentrations of chemicals into the air, it will even increase the degree of air pollution in general. For example, in Europe and America, releasing ozone into the air is strictly prohibited.
Whether it is absolutely safe.
Buying an air purifier is nothing more than getting healthy and fresh air. Whether the air purifier is safe or not is the basic premise to decide whether it is desirable or not. The shell, movement and purification technology of air purifier will directly affect the air.
Safety of purifier. The purification technology should be the same as the positive and negative ions in nature, and its safety has been certified by 13 foreign institutions.
Whether to meet the specific purification needs.
As far as air purifiers are concerned, the purification function is the most concerned function. If your requirements for indoor air purifiers are only based on improving indoor air quality, then you can choose the type with pure air purification and high cost performance.
As people's requirements for quality of life are getting higher and higher, the demand for air purifiers is no longer simply to purify indoor air. For example, people who work in a closed air-conditioned room will choose a humidified air purifier with skin beautifying function when choosing an air purifier, because the indoor air becomes very dry, and the skin will also become dry due to the dehumidification function of the air conditioner.
However, people who stay in crowded rooms for a long time need to breathe fresh and sterile air at close range. When purchasing an air purifier, they will first choose a small K air purifier suitable for the desktop.
People who own their own cars should choose car air purifier to purify all kinds of car odors and even alleviate driving fatigue.
Function of air purifier
1, especially suitable for patients with respiratory diseases;
Living in polluted air for a long time will lead to decreased respiratory function and aggravated respiratory symptoms, especially rhinitis, chronic bronchitis, bronchial asthma, emphysema and other diseases. In addition, the prevalence of lung cancer and nasopharyngeal carcinoma will also increase.
2, especially suitable for home decoration:
The harmful substances produced by indoor decoration are mainly formaldehyde, benzene and benzene series. Formaldehyde has been identified as a carcinogen and teratogenic substance by the World Health Organization. Long-term exposure can cause various respiratory diseases, menstrual disorders, leukemia, and memory and intelligence decline of teenagers.
3, especially suitable for children:
Children's body is developing, and the immune system is easily affected by indoor air pollution, which leads to decreased immunity, delayed physical development, induced blood diseases, increased the incidence of asthma in children and greatly reduced children's intelligence.
4, especially suitable for office workers:
Working in a high-end office building is an enviable career. However, in a closed environment with constant temperature and poor air quality, it is easy to cause dizziness, chest tightness, fatigue, emotional ups and downs and other uncomfortable symptoms, affecting work efficiency, causing various diseases, and even causing cancer in severe cases.
5, especially suitable for the elderly:
The physical function of the elderly is declining, and they are often troubled by various chronic diseases. Air pollution will not only lead to respiratory diseases such as tracheitis, pharyngolaryngitis and pneumonia in the elderly. It can also induce cardiovascular diseases such as hypertension, heart disease and cerebral hemorrhage.
6, especially suitable for pregnant women:
Pregnant women will feel unwell in a room with serious air pollution, and have symptoms such as dizziness, sweating, dry tongue, chest tightness and vomiting, which will have a negative impact on the development of the fetus. Children born to pregnant women who breathe fresh air are three times more likely to have heart disease.
7, especially suitable for drivers: lack of oxygen in the car, serious automobile exhaust pollution.
8, especially suitable for hospitals: reduce infection and prevent the spread of diseases.
