For car purifiers, there are currently two main methods: decomposition and adsorption. Among them, decomposition is mainly to decompose formaldehyde and bacteria in the air through products such as photocatalysts and solid catalytic alkali, to achieve the effect of air purification. The adsorption scheme is to adsorb and filter formaldehyde, TVOC, etc. in the air through the multi-layer filter device inside the purifier. For example, the Mijia Xiaomi car air purifier has two types: a PM2.5 filter element and a formaldehyde removal filter element. If the PM2.5 filter element is installed, there is no formaldehyde function.
Types of Car Air Purifiers
At present, there are many models of car air purifier sold on the market, which mainly consist of five purification elements, and the general functions are:
(1) Filter type car air purifier
The filter-type car air purifier can effectively purify harmful substances such as dust, formaldehyde, benzene, bacteria, etc. in the car, but the filter-type car air purifier only purifies the passively inhaled air. Restrictions, generally there is not enough fan power to inhale and purify the air in the car, so the purification ability of the filter-type car air purifier is also limited, and the purification effect is effective.
(2) Electrostatic dust-collecting vehicle air purifier
The electrostatic dust-collecting vehicle air purifier needs to cooperate with other equipment to achieve an efficient purification effect, because the electrostatic dust-collecting vehicle air purifier cannot completely absorb and eliminate odors, nor can it completely decompose toxic chemical gases. At the same time, its purification effect and purification efficiency will decrease with the accumulation of suspended particles, and the dust collecting plate needs to be cleaned frequently to restore its effect and efficiency, so the maintenance cost is high.
(3) Ozone car air purifier
The working principle of the ozone car air purifier is to generate ozone to purify the air in the car to achieve the effect of improving the air quality in the car. Although, ozone has a certain effect on bacteria, especially against amines, nicotine, bacteria, etc. However, when using this type of car air purifier, it is necessary to pay due attention to the concentration of ozone in the car, because if the concentration of ozone is too high, it will cause secondary pollution and cause harm to human health.
(4) Plasma ion group car air purifier
Plasma ion cluster car air purifier is a patented technology car air purifier produced by Sharp. Using the plasmonics generator to spray a unique, efficient, and safe plasmonics to remove formaldehyde, benzene, bacteria, odors and allergens, etc.; the special car technology for cars uses the Coanda effect to make the plasmonics reach every part of the car. Corner; use up to about 17,500 hours before needing to replace the ionizer.
Car air purifier purchase and maintenance
Whether it is convenient and safe to place in the car. Convenient and safe are the primary considerations. Because, if it is inconvenient to place in the car or there is a safety hazard after being placed, no matter how good the air purifier is, it cannot be used.
(1) Appearance volume.
(2) Manufacturing materials.
Generally speaking, wear-resistant and high-temperature-resistant materials are better than more fragile materials.
(3) Whether the air purification in the car is comprehensive, efficient, convenient, and safe are the most basic considerations, and the purification effect is the key decisive factor.
(1) Filter purification. The maintenance of such products depends on different filters. Some filters need to be cleaned regularly to maintain the purification effect, and some do not, but most of them need to be replaced.
(2) Ion purification. The maintenance of such products generally only needs to replace the ionizer. Some are changed every year, and some are changed every year. The longest is 6 years.
The root cause of the decline in indoor air quality is poor ventilation and excessive indoor air pollutants. Therefore, to create a good indoor environment, you can start with the following 6 aspects.
(1) Control the quality of decoration materials to prevent indoor air pollution
Inferior materials release a large number of organic gas pollutants, including formaldehyde, benzene, xylene, and other volatile organic gases, which can cause headaches, insomnia, cough, tears, and even cancer. When choosing decoration materials, try to choose a building material brand with a high reputation. Do not blindly pursue low-cost products, because environmentally friendly materials have low formaldehyde content but high costs, and some unscrupulous manufacturers even use inferior materials to control costs.
(2) How can we prevent indoor air pollution – don’t rush to move in after buying a new house
After purchasing a new house or decoration, you should first find the indoor environmental testing department for testing the air quality. Listen to the opinions of experts, and choose the appropriate time to move in. The reason for the long-term vacancy of new houses is to allow the pollutants released by the walls, floors, furniture, etc. Let your house be fully volatilized in advance to ensure the air quality after move-in. After moving into the house, we must also ensure that there is enough fresh air in the room to effectively improve indoor air pollution.
(3)Choose an effective indoor air purification appliance to prevent indoor air pollution
We can choose air purification appliances with different functions according to different pollutions in the living room, and kitchen, such as air purifiers, range hoods, etc. An air purifier can adsorb air suspended solids, filter dust, bacteria, and viruses, and remove odors. If you put an air purifier at home, it can bring you clean air and a comfortable living environment. When turning on the purifier, it is necessary to keep the room relatively sealed.
(4)Ventilation is the most economical way to improve indoor air quality
Whether there are people in the house or not, we should ventilate as much as possible. On the one hand, it is conducive to the emission of indoor pollutants, on the other hand, it can be the release of toxic and harmful gases in decoration materials as soon as possible. Ventilation is the key measure to improving indoor air quality. Indoor air pollution diluted with fresh outdoor air will reduce the concentration. However, if the outdoor air is heavily polluted. Such as sandstorms, respirable particulate matter, or other pollutants in high concentrations. In this condition, we should make ventilation avoided.
(5)How can we prevent indoor air pollution–Place Green plants to absorb harmful gases
The green plants used to decorate the living room are a powerful tool for purifying indoor air quality. Such as hanging orchids, aloe vera, green lotus, and so on. Plants have a certain absorption capacity. In general, large-leaf and vanilla plants absorb formaldehyde better. Maybe green plants have a certain purification effect. But their purification effect also depends on the specific conditions and types of pollutants.
(6)Handle pet hair properly | indoor air pollution
Odors, pet hair, bacterial viruses. These questions bother every pet owner. If you have a pet, you should wash your hands after treating them, and don’t bring them into the bedroom. Because pet dander particles are usually larger, although they do not enter the respiratory tract, they are prone to allergies.
