Ann Arbor-based TusStar and Chinese nanotechnology company Neatrition have received U.S. Nelson Lab approval for their NMV95+ mask products featuring a nano-scale surface in both a new headband design and the existing over-the-ear style.
In addition to a viral filtration efficiency of 99.8 percent reported through U.S. Nelson Lab tests, the NMV95+ products passed a N95 sample test in National Institute for Occupational Safety and Health (NIOSH) labs and are moving ahead through the final quality assurance process.
The middle melt-blown material in the NMV95 mask is said to provide a filtration rate of more than 95 percent and the droplet repellent top layer can block 90 percent of small particles and water droplets. Because of this, the NMV95 masks can last 10 times longer than regular N95 mask.
The companies say the products are designed with soft-sewn stretch knit ties and carefully crafted inner mask design to provide a comfortable fit that is easy to wear for long stretches and is exceptionally breathable while shielding users from respiratory droplets and other particulate matter during the current COVID-19 crisis and beyond.
A new Neatrition anti-fog glass cloth also has been introduced for mask users who wear glasses or goggles. The product is reported to be very popular in hospitals in Wuhan, China and Italy. A single application of the cloth can make glasses or goggles free of fog for 24 hours of use and the cloths can be reused at least 100 times. Currently the first 50 mask purchasers can get $9 worth anti-fog cloths free by applying coupon code antifog50 with their online order.
Neatrition worked with Tsinghua University, a major research university in Beijing, to develop and create these new nano medical masks. They are made in labs in China and overseen by academic researchers to ensure clean standards and a top-of-the-line product.
“The nano-scale top layer structures are similar to a shark skin,” says Frank Ni, president of TusStar. “Shark skin has those micro nano sharp teeth that make them much cleaner than whales. With U.S. Nelson Lab and NIOSH N95 certification test approval we are ready to move forward with the next innovation of this breakthrough product.”
TusStar is donating 10 masks to Henry Ford Hospital in Detroit for every 100 sold. The first delivery of masks was made on May 29.
