In view of China's air quality and PM2.5 status, German filtration expert MANN+HUMMEL has developed a new type of high-efficiency filter media and related technologies for automotive air conditioning filters. At present, new filter materials and technologies have passed laboratory standard tests and actual vehicle tests have been conducted. The test results show that air-conditioner filters using high-efficiency filter media and new technologies have reached industry-leading levels in improving filtration efficiency, and can effectively reduce PM2 in the short time after the vehicle is started and the air conditioning system is turned on. 5 concentration. This is another masterpiece created by the MANN+HUMMEL R&D team specifically for the Chinese market, setting a new industry benchmark for air conditioner filters in China.
MANN + HUMMEL developed and launched new air filter filtration technology
Due to the influence of PM2.5 , the driver's attention to the air quality in the car has been increasing. It is understood that PM2.5 refers to particles with a particle size of 2.5 microns or less in the atmosphere. Because these particles are very small, they will directly enter the respiratory tract with the respiration, accumulate in the lungs, and even infiltrate into the blood. The harmful substances they load seriously harm human health. At present, China has not yet begun to conduct universal detection of PM2.5. Only major cities such as Beijing and Shanghai can detect PM2.5. Routine monitoring programs in other regions include only inhalable particles with a particle size of less than 10 microns (PM10). ), Nitrogen dioxide and sulfur dioxide; At the same time, the test method for PM2.5 air conditioning filters has not been clearly defined and standardized. In terms of current air quality in China, it is difficult to compare the filtration performance of ordinary air-conditioning filters, and air-conditioning filters on the market currently do not provide sufficient filtration efficiency.
As one of the leaders in the filtration industry, MANN+HUMMEL believes that the automotive air-conditioner filter for the current status of PM2.5 has a filtration efficiency of at least 90% for particles with a particle size of 0.3 to 2.5 microns. Compared with existing air conditioner filters in the market, MANN+HUMMEL's new filtration technology can effectively reduce the PM2.5 concentration in the vehicle in a shorter time. MANN+HUMMEL provides PM2.5 test equipment for the owner. The PM2.5 sampling and measuring device and data analyzer are installed in the vehicle to test the filtration efficiency of the PM2.5 air conditioner filter.
"As a filter specialist who has been firmly established in the Chinese market for 17 years, MANN+HUMMEL is committed to contribute to the sustainable development of China and the construction of a better environment with professional solutions." Vice President of MANN+HUMMEL Group Mr. Josef Parzhuber, Chief Executive Officer of Asia Pacific, said: “R&D localization is crucial for MANN+HUMMEL’s development in China. We continue to upgrade the R&D level of local engineers and provide them with the most advanced R&D equipment, so that we can develop the most suitable for China. Market demand products.The newly developed new air-conditioning filter media and technology for PM2.5 is the latest achievement under our R&D localization strategy. We hope that our innovative products and technologies will help Chinese consumers create a more secure, Clean driving environment, and continue to promote the development of the latest technology in the filtration industry."
In addition to the current filtration technology for PM2.5, MANN+HUMMEL has also developed an antibacterial and anti-allergic MANN filter multi-function air conditioning filter. The test results show that the air-conditioning filter with antibacterial function has a reduction rate of more than 98% for bacteria and mold. The anti-allergic filter can effectively prevent pollen, dust mites and other allergens in the air from affecting passengers in the sensitive body. At present, MANN brand filter multi-function air-conditioning filter has been listed in China, widely used in all kinds of passenger cars.
With the in-depth development of the Chinese market, MANN+HUMMEL has continuously strengthened localized R&D measures and continued to invest in engineering and test equipment. Its China R&D center in Shanghai is equipped with high-standard laboratory and experimental equipment, including built The advanced air conditioning filtration laboratory. At the same time, MANN+HUMMEL continues to invest in simulation software and testing every year to support rapid and efficient product development.
