Smog is an unsolvable national problem every winter. We can use air purifiers indoors, but we can’t wear gas masks when going out. Generally, medical Masks don't work at all in smog. A design team called GUTS AIR has designed a wearable air purification mask that weighs only 90 grams in response to the increasingly serious smog.
The mask has three layers of filtration: water-based non-woven fabric, high-density electrostatic non-woven fabric, and ultra-fine composite fiber. It has been professionally tested and certified by NELSON in the United States to effectively filter out particles above 0.076 mm. Contains nano-zinc antibacterial agent, and the sterilization rate reaches 99% according to SGS standards. The built-in high-efficiency negative ion generator can make the concentration of negative ions in the mask reach 2 million/cubic centimeter. The unique design similar to the human heart valve greatly improves the air purification capacity and also avoids re-inhalation of exhaled CO2. The mask is ergonomically designed to fit perfectly on the face and is very comfortable to wear. The mask has a built-in 200MAH lithium polymer battery, which is charged using the USB interface and can be used continuously for 4 hours after being fully charged.
Currently, the product is crowdfunding on JD.com http://z.jd.com/project/details/2899.html
