According to the principles of domestic air purifiers in recent years, the development history of purifiers is summarized, which can be roughly divided into the following categories:
1. Filter type air purifier. This type of air purifier is designed based on the filter performance of the filter. It has the functions of filtering and adsorbing impurities. It can effectively adsorb and purify the particulate matter in the indoor air and a few harmful gases in the decoration. It has a significant effect on the purification of PM2.5 in the air, but The chemical air pollution caused by decoration in the indoor air cannot be eliminated from the source, and it has a purifying effect on viruses and peculiar smells.
According to the principle of the filter type air purifier, its shortcomings are determined: in the process of filtering and adsorption, the filter will slowly saturate until it loses its effect. Therefore, consumables such as filters need to be replaced regularly. If they are not replaced in time, secondary pollution will easily occur. Most air purifiers currently on the market use this method.
2. Electrostatic dust-collecting air purifier. Some of the principles of this type of air purifier are based on the performance of the filter screen, adding electrostatic dust removal, electric plate dust collection, negative ion generator and other functions. This type of purifier can not only remove dust, but also has the function of sterilizing, removing peculiar smell and decoration pollution and other harmful gases. Some use the electrostatic dust collector technology alone, which has limited purification effect and is easy to produce ozone during work.
3. Air purifier using molecular complex technology. The principle of this type of air purifier is to use molecular complexing agents to dissolve the generated gas molecules in water to achieve the purpose of air purification. Molecular complex technology has reached the requirements of product marketization, and the purified product is relatively environmentally friendly, and compared with HEPA filters and activated carbon, it is also relatively environmentally friendly.
4. Water washing air purifier. The principle of this type of water washing air purifier is to absorb and decompose particles and harmful gases in the air through a nano-scale water molecular filter formed by water, which improves the adsorption efficiency and saturation capacity; The natural water molecules produced by the air purifier at work can moisturize the air and increase the comfort of the human body, and the natural negative oxygen ions released can freshen the air and relieve human fatigue; the washing air purifier does not produce secondary pollution, which greatly saves the cost of consumables , While reducing secondary pollution to the environment, it is an ideal all-round air purifier. At the same time, some washing air purifiers adopt advanced monitoring systems, electronic display systems and intelligent control systems in the control system, highlighting the appearance design of the washing air purifiers, making the washing air purifiers a new type of household appliances that consumers love .
