OK. Basically, all fabric surfaces can be sprayed, so it can be sprayed on all kinds of masks.

Not recommended, the water-repellent agent cannot grip the skin firmly and falls off easily. In addition, although it has passed the test of being hypoallergenic and non-irritating, the water-repellent agent will produce a film on the surface of the skin, which may make some people feel uncomfortable.

When spraying, please make sure the distance between the spray bottle and your face is greater than 30 cm, so there is no danger even if you inhale a little. However, if you spray it on your face, or get it too close to your face and inhale a large amount, you will feel uncomfortable due to the irritation of isopropyl alcohol, so please avoid it. If you accidentally inhale a large amount and the discomfort persists, please take this product and seek medical attention immediately.

Won't. Taking disposable medical masks as an example, if the isopropyl alcohol component in this product is sprayed in large amounts and the mask is completely wet, it will indeed reduce the effectiveness of the electrostatic filter layer of the mask by 15 to 20%. However, in general use of this product, you only need to spray a thin layer on the surface of the mask, and the degree of infiltration of the filter material by isopropyl alcohol is very limited or even non-existent. Therefore, in our tests, the overall filtration efficiency was reduced by close to 0%, so please feel free to use it. Another reminder, even if this product is sprayed, it is not recommended to reuse the "disposable medical mask" multiple times! Because of its loose structure and reliance on electrostatic adsorption, it is recommended to replace it within five uses at most to ensure that the performance does not drop too much. Masks that do not use electrostatic filtration (such as net convection masks) are not affected.

Won't. We have sent it to the Textile Research Institute (TTRI) for testing. The surface tension of the anti-repellent agent is not strong, so it will only cover the fibers of the fabric, but will not cover the holes between the fibers, so it will not affect the breathability of the fabric. oh!

Both alcohol and hypochlorous acid water are "single sterilization" because alcohol evaporates quickly and hypochlorous acid water degrades quickly. Both are only effective for a few minutes and are ineffective after that. The antibacterial shield spray is a "long-lasting sterilization". As long as it is not damaged or removed by external forces, its antibacterial effect can last for more than 120 hours! During this period, germs that fall on or adhere to the surface will be killed by the antibacterial shield, keeping the surface sterile.

Quaternary ammonium salts are actually antibacterial agents that have been widely used for a long time. The "only three" safer ingredients for hand washing (hand disinfectant) recommended by the US FDA are: alcohol, isopropyl alcohol and quaternary ammonium salts. , and the quaternary ammonium salt is the least irritating and allergic among the three substances, and is relatively safe because it does not support combustion. Therefore, the antibacterial ingredients in many baby wipes use quaternary ammonium salts.

In addition, the U.S. Environmental Protection Agency (EPA) and Health Canada have explicitly recognized quaternary ammonium salts as effective ingredients in killing COVID-19 on their websites! However, generally the quaternary ammonium salt solution will gradually become ineffective after being removed a few times. How does net convection make the quaternary ammonium salt achieve long-term antibacterial effect? The secret lies in the "water-repellent agent" (or water-repellent agent). We use a special process to evenly blend the quaternary ammonium salt and water-repellent agent. Therefore , the anti-repellent agent can firmly grasp the fibers of the textile, and the anti-repellent agent can firmly grasp the quaternary ammonium salt , so the fibers of the textile can be sterilized for a long time! And this is where the patented technologies of Net Convection and Xunuo Biotech lie.

You can confirm by dripping some water. As long as the water-repellent ability is still there, the antibacterial power is still there!

Yes, as long as it is textile, it is suitable. For example, it can be used on collars, cuffs, helmet linings, socks, insides of cloth shoes, non-woven shopping bags, etc.!
