From "Kangfeng Information Dynamics"
On December 14, 2020, AOP-KF® solid alkali mask passed the latest ISO18184:2019 authoritative certification test. It has become the world's first mask that is proven to be effective against the new coronavirus with an inactivation rate of 99.31% and can be reused many times. This is a landmark event of my country's medical protective masks. It is another leading achievement of our country in the world's fight against the new crown virus epidemic.

▲KANGFENG AOP-KF® SOLID ALKALI MASK
The AOP-KF® solid alkali mask is independently developed by Shenzhen Kangfeng Environmental Technology Development Co., Ltd., and uses the world-class breakthrough technology AOP-KF® solid alkali. AOP-KF® solid alkali masks have also passed the inspection and identification reports of many countries such as Europe, Japan, South Africa, etc. The AOP-KF® solid alkali masks have an inactivation rate of up to 99% in killing viruses, bacteria and fungi, and the use time is up to 7 days. It can not only kill bacteria and viruses including new coronavirus, H1N1 influenza virus, Staphylococcus aureus, coliform, respiratory syncytial virus, hemolytic streptococcus, etc., but also relieve respiratory diseases such as rhinitis, bronchitis, and asthma.
CHOOSE ANTI-VIRUS MASK, ISO 18184:2019 CERTIFICATION TO FIND OUT
ISO 18184:2019 certification is currently the latest and most authoritative international textile antiviral test standard. It is used to test the antiviral and antibacterial activity of textiles. It is the highest standard for testing whether protective mask products are of high quality. The ISO 18184:2019 testing method is also an authoritative testing method suitable for medical-grade products. Passing this testing method means high-quality assurance of medical-grade products. In the report on December 14th, it has been confirmed that AOP-KF® solid alkali masks have an inactivation rate of up to 99.31% against the new coronavirus, marking the success of this technology in the field of textile anti-virus.

It is worth noting that Shenzhen Kangfeng Environmental Technology Development Co., Ltd., which develops and produces AOP-KF® solid alkali technology, is also my country’s 2020 "Antibacterial and Antiviral Mask" standard (T/CSTE 0011-2020), "Medical and similar uses The drafting unit of multiple respiratory safety industry standards, including the "Classification of Sterilization Performance of Air Disinfectants and Purifiers" (T/GIEHA 021-2020).
HOW EXACTLY DOES AOP-KF® SOLID BASE KILL THE NEW CORONAVIRUS?
AOP-KF® solid alkali can regenerate high-concentration gas-phase hydroxyl radicals in situ, and achieve efficient sterilization and detoxification through catalytic oxidation. If the new coronavirus is attached to the mask, it will be oxidized and killed after contact with the solid alkali, and its replication will be blocked, avoiding secondary pollution, and it is a safe and efficient new anti-virus method.

▲THE USER WEARS KANGFENG AOP-KF® SOLID ALKALI MASK
The AOP-KF® solid alkali mask itself has antibacterial and antiviral effects. The contact of this protective mask with the mask during use will not cause the spread of the virus, so no complicated disinfection treatment is required. Under the condition of maintaining normal virus filtration and inactivation performance, the disinfection function of the mask can be used repeatedly for at least 7 days. This function has passed the sterility test on 7th, 2020 in South Africa.
In the 7-day sterility test, the mask was used normally for 8 hours a day, and the inside and outside of the mask were sampled for testing. The test results were all aseptic growth.

At the same time, AOP-KF® solid alkali masks are environmentally friendly and are not affected by indoor and outdoor, weather, temperature and humidity, and can maintain their strong anti-virus and antibacterial properties for a long time in low temperature and hot weather. In terms of comfort, the mask material is special to avoid the sultry sensation caused by breathing resistance and cause discomfort to the human body.
WHERE DID THE PATENTED AOP-KF® SOLID ALKALI TECHNOLOGY FOR KILLING THE NEW CORONAVIRUS COME FROM?
AOP-KF® solid alkali is researched and developed by a team of scientists from Shenzhen Kangfeng Environmental Technology Development Co., Ltd. focusing on the field of respiratory safety research. The technology has obtained Chinese and American invention patents. AOP-KF® solid alkali mask has obtained many certifications such as EU CE certification and US FDA certification.
The quality of Kangfeng series products, including AOP-KF® solid alkali masks, is leading international standards for aldehyde and bacteria removal. Kangfeng medical products have been widely used in the field of micro-environment air purification and disinfection in major tertiary hospitals in China. Kangfeng has entered the subdivisions of households, vehicles, cold chain cold storage, etc., and continues to promote the upgrading of products and technologies.
It is reported that Shenzhen Kangfeng Environmental Technology Development Co., Ltd. has provided safety and epidemic prevention guarantees for the indoor training venues of the 2022 Beijing Winter Olympics.
AOP-KF® solid alkali masks have achieved an inactivation rate of 99.31% of the new crown virus, ensuring the safety of people's breathing, and fully cooperating to win this epidemic prevention war.
