First, whether it can have absolute security.
Purchase of air purification equipment is nothing more than to use it in exchange for healthy and refreshing air. Whether an air purification equipment can be safe or not is the fundamental prerequisite for deciding whether it is desirable. The shell, core and purification technology of air purification equipment will directly affect the safety of air purification equipment. Purification technology should choose the same ion purification technology as the positive and negative ions in nature, and 13 foreign agencies have certified its safety.
Secondly, whether we can have scientific purification principle to achieve the effect of efficient air purification equipment.
There are five internationally accepted air purification principles: physical, electrostatic, chemical, negative ion and composite. Generally speaking, physical purification is the most common and effective method. For example, dust, pollen, allergens, viruses and other particulate matter can be filtered by HEPA technology in physical purification mode, while harmful substances such as benzene, toluene, formaldehyde and other odors can be purified by activated carbon adsorption in physical purification mode.
According to the active direction of purification mode, purification mode can be divided into active direction, active purification mode (air purification) and passive purification mode (fixed point purification) and active and passive combined purification mode. Passive purification method can only purify the inhaled air; active purification method can purify the whole space. Active and passive combined purification is the separation of the two, and the effect is better.
Active purification is a controversial technology in the world. As air pollutants are generally one-thousandth or even lower in concentration, and active purification requires spraying higher concentrations of chemicals into the air, so as to increase the level of air pollution in general. For example, the release of ozone into the air is severely prohibited in Europe and the United States.
Third, whether it can meet the detailed purification needs.
As far as air purification equipment is concerned, purification function is the most concerned function. If your request for indoor air purification equipment is only based on the improvement of indoor air quality, you can choose pure clean air, cost-effective type.
With the improvement of people's demand for quality of life, the demand for air purification equipment is no longer simply to purify indoor air. For example, those who work in closed air-conditioned rooms, because the dehumidification effect of air conditioning makes the air in the room very dull, the skin also becomes dull, so when choosing air purification equipment, they will choose humidified air purification equipment with skin beauty function.
For a long time, people with large population and large indoor pollution need to breathe clean and bacteria-free air at close intervals. When choosing air purification equipment, they tend to buy small K air purification equipment which is suitable for desktop.
People with their own cars should choose on-board air purification equipment to purify all kinds of car odors, and even alleviate driving fatigue.
Fourth, the separation of market sales and third-party authoritative certification to stop purchasing.
A high-quality household air purification equipment must have the ability of sterilization and odor removal. When purchasing air purification equipment, we should pay special attention to its bactericidal power and odor removal ability. Generally speaking, sales volume is a key market test index.
In addition, such as furniture under the table, sofa mattress and other pure air concentration of the central breeding of Staphylococcus albicans, Escherichia coli, influenza viruses and other common planktonic bacteria; the newly decorated house is full of formaldehyde, benzene and TVOC and other harmful gases. The purification effect of air purification equipment on these harmful substances will be more convincing if it is verified by the third party authority.
