The working principle of air purifier
Air purifiers mainly have three working principles: passive, active and mixed active-passive. Passive adsorption and filtration is the most common, like a diligent bee, the fan will be pumped into the machine, through the built-in filter, dust collection filter can intercept large particles, formaldehyde filter can adsorb formaldehyde and other harmful gases, deodorization filter is responsible for removing the odor, HEPA filter is highly efficient filtration of fine particles, different levels of HEPA filters for particles of different sizes with different filtering effects, the higher the level, the better the filtration effect. Different levels of HEPA filters have different filtration effects for particles of different sizes, the higher the level, the better the filtration effect, just like the old poem “Thousand Amoy Ten Thousand Lu漉, although hard, blowing through the wild sand to gold”, can more effectively remove pollutants, such as PM2.5 and even finer. Active type is free from the fan and filter limitations, the active release of purification and sterilization factors into the air, such as silver ion technology, anion technology, low-temperature plasma technology, etc., these factors through the air diffusion, to reach all corners of the indoor purification without dead ends. Active-passive hybrid is a combination of passive purification technology and active purification technology, both advantages, can be more comprehensive purification of air.
Applicable scenarios of air purifier
Newly renovated houses: the renovation process will release formaldehyde and other harmful gases, its volatilization period of up to 3-15 years, like a stubborn “little monster thin”, and the air purifier can be incarnated as a “superhero”, effective adsorption and filtration of these harmful gases for the health of family members. The air purifier can act as a “superhero” to effectively adsorb and filter these harmful gases to protect the health of your family.
Families with sensitive respiratory groups: Infants, young children, the elderly, asthmatics and other sensitive respiratory groups, the body's resistance to pollutants is weak, it is easy to be affected by air pollution, air purifiers can provide them with a relatively clean respiratory environment, as if they put on a layer of “protective cover”.
Families with pets: Although pets are adorable, their hair and dander can become allergens and cause problems for some people. Air purifiers can effectively remove pet hair and dander from the air, alleviating allergy symptoms and allowing pets and family members to live in harmony.
Families of city dwellers: The air in heavy traffic areas contains a lot of pollutants such as car exhaust and dust, and these particles can cause serious damage to the human respiratory system. Air purifiers can filter out these pollutants, so that city dwellers can breathe relatively fresh air when they return home, as if the “people in the hustle and bustle of the city to create a small ‘paradise’.
How to choose an air purifier
Define the main pollutants: according to the type of indoor pollutants to choose an air purifier with one or more pollutant removal ability. For example, in the haze area, you need to choose a product marked with particulate matter CADR value; new home renovation, then you need to choose a product marked with formaldehyde CADR value, benzene CADR value and other indicators; if someone at home smokes, want to remove second-hand smoke, then you have to choose particulate matter and gaseous pollutants purification of strong products; pet families, you need to choose to remove the hair, in addition to the odor of the product.
Determine the use of area: clean air volume (CADR) and cumulative purification volume (CCM) is the air purifier is the most important two lineal energy parameters. the larger the CADR value, reflecting the air purifier purification ability, the larger the applicable area, the faster the removal of indoor air pollutants. Generally speaking, according to the room area to choose the appropriate CADR value of the air purifier, like to the room tailored to a suitable “clothes”.
Compare the cost of using the product: the larger the CCM value, the stronger the continuous purification ability of the air purifier, the longer the life of the filter, and the longer the use of time, which can reduce the cost of replacing the filter at a later stage. In addition, you also need to consider the energy consumption of the air purifier. Choosing a product with low energy consumption can not only protect the environment, but also save electricity costs.
Examine the additional features: nowadays, there are more and more additional features of air purifiers, such as automatic air quality monitoring, APP remote control, etc. These features will increase the cost while increasing the convenience of the linea. You can choose whether you need these additional features according to your needs and budget. In addition, the air purifier is a high-consumption electrical appliances, after-sales service is perfect, filter purchase and replacement is convenient, the length of the warranty period, etc., need to be considered, after all, “the details determine success or failure”.
