1. Low-temperature asymmetric plasma. The low-temperature asymmetric plasma module forms an asymmetric plasma electric field through high-voltage, high-frequency pulse discharge, which causes a large amount of plasma in the air to collide step by step. It produces electrochemical reactions and rapidly degrades toxic and harmful gases, living viruses, bacteria, etc., so as to efficiently kill viruses, sterilize, remove odors, smoke, and dust, and produce non-toxic and hazardous substances. It is called the most advanced environmental and health science in the 21st century. High and new technology worth looking forward to. It can coexist with man and machine, purify at the same time without the need for personnel to leave; energy saving and consumption reduction, can save 80% of the electric energy compared with the same period; lifelong no disassembly and washing. It has the ability to quickly eliminate viruses, super purification ability, efficiently eliminate odors, eliminate static electricity, and increase oxygen content.
2. Chemical preparations. The main product is air freshener (car perfume). Its product is cheap, but it can only cover up some peculiar smells. In addition, complex chemical reactions occur under the action of sunlight, which become new pollution in the car, and it is impossible to eliminate harmful gases.
3. Chemical decomposition. The main working principle is the ionizer ozone generator, which is inexpensive and has more functions than fresheners. It can increase the number of negative ions in the air and reduce the solid dust in the air. It has a sterilization effect but has little effect on decomposing harmful gases such as formaldehyde. The ozone generator produces a
Clean Room Project and large amount of high-concentration ozone, which may kill human white blood cells while killing some viruses and bacteria, which may cause cancer. Negative ions are easy to absorb dust and adhere to the ceiling of the inner wall of the car, causing the interior of the car to be particularly shallow The colored car will gradually become gray-black.
4. Adsorption and volatilization. It is a purifier using Chinese herbal medicine as a medium. It is inexpensive and has a certain antibacterial function. However, Chinese herbal medicines basically cannot purify in a solid state. The use of Chinese herbal medicine in the purifier is only a small amount. After reaching saturation, it will not sterilize and easily become bacteria. The replacement filter element involves the difficulty of harmless disposal.
5. Adsorption. Activated carbon filter can absorb certain bacteria, dust and harmful gas in a short time. It is low in price. It can filter certain bacteria and dust. It has adsorption function, but it has no selective adsorption. The adsorption rate of water is 45%, generally one month. After it can reach saturation, it needs to be replaced. Cannot be recycled. After reaching saturation, not only can it not be sterilized, but it can easily become a multiplication body of bacteria. The replaced filter element also involves the difficulty of harmless disposal.
