Kronos Patent Pending Graphene Masks Revealed by Independent Lab as World’s Most Effective Providing 99.9% Viral and Bacterial Filtration Efficacy

Parkersburg, Feb. 15, 2022 (GLOBE NEWSWIRE) — Kronos Advanced Technologies, Inc. (OTC: KNOS), revenue-generating product development and production company that has significantly changed the way indoor air is filtered and disinfected, announces test results from Nelson Labs demonstrating significantly enhanced bacterial filtration efficiency (BFE) and viral filtration efficiency (VFE). As the COVID-19 pandemic wanes, the use of facemasks has become commonplace, if not endemic. The performance of medical facemasks is assessed using Bacterial Filtration Efficiency (BFE) tests and Viral Filtration Efficiency (VFE) tests.

Kronos’ designed and the U.S. manufactured 5-ply graphene face masks remove 99.9% of bacteria and virus particles compared to the common and far less efficacious ASTM level 3 mask. (ASTM Level 3 is the FDA’s highest rating for medical and surgical face masks). The Kronos face mask is the only 5-ply graphene mask known to be manufactured in the USA.

With BFE and VFE levels over 99.9%, the Company believes that these are the highest filtration efficiency numbers for any face masks in the market. All test method acceptance criteria were met. Testing was performed in compliance with US FDA good manufacturing practice (GMP) regulations 21 CFR Parts 210, 211, and 820.

While the 2019 pandemic appears to be degrading into endemic status, mask-wearing has likely become a permanent way of life for many and will likely continue into common, if not mandatory, use by the food industry, adding to the common use pre-pandemic of doctors, nurses, and hospital workers. Furthermore, the world will likely stock up on the best masks in order to be ready for a new covid-19 strain or unrelated pandemic feared to emerge in the near future.

In a recent MAYO CLINIC article, entitled, How well do face masks protect against COVID-19? “Get answers to your questions about face masks, including how to use them properly,” it stated:

“Can face masks help slow the spread of the virus that causes coronavirus disease 2019 (COVID-19)? Yes. Face masks combined with other preventive measures, such as getting vaccinated, frequent hand-washing, and physical distancing, can help slow the spread of the virus that causes COVID-19.”

The U.S. Centers for Disease Control and Prevention (CDC) recommends masks for the general public. If you’re fully vaccinated and are in an area with a high number of new COVID-19 cases, the CDC recommends wearing a mask indoors in public and outdoors in crowded areas or when you are in close contact with unvaccinated people. People who haven’t been fully vaccinated should wear face masks indoors and outdoors where there is a high risk of COVID-19 transmissions, such as crowded events or large gatherings.

The CDC says that you should wear the most protective mask possible that you’ll wear regularly and that fits. Prior to Kronos’ new product, KN95s and medical masks provided the next highest level of protection.

Centers for Disease Control (CDC) and Prevention still recommends that masks be worn in areas of substantial or high transmission and in educational settings, regardless of vaccination status.

“We’re not quite there yet,” CDC Director Dr. Rochelle Walensky told radio station WYPR this week. The CDC “still recommends that all schools encourage students to wear well-fitting masks consistently and while indoors. And that’s consistent with our guidance that still also recommends that people mask in public indoor settings in areas of high or substantial transmission.”

Nationwide, nearly 99% of U.S. counties are still reporting high community transmission.

“We owe it to our children to make sure that they can safely stay in school. Right now, that includes masking. We’ve seen outbreaks that have occurred in communities where students were not masked in schools and had to close. … And much of our guidance is based on the amount of community transmission,” Walensky added.

Recently, 11 states have announced changes to their statewide masking policies, with some governors moving to end universal indoor and outdoor mask mandates, while others have lifted statewide face-covering requirements for schools.

The Transportation Security Administration (TSA) is extending the face mask requirement for individuals across all transportation networks throughout the United States, including at airports, on board commercial aircraft, on over-the-road buses, and on a commuter bus and rail systems through March 18, 2022.

A poll by Washington Post conducted in July 2021 found that 67% of respondents intend to wear masks whenever they’re sick, and 43% plan to wear masks in crowded places even after COVID-19.

“Our goal is to provide the best available protective face masks on the market for those in higher exposure risk environments with the best technology available – and our Kronos® graphene technology achieves this not only as of the highest protection properties but also by completely reducing the number of viable bacteria and virus particles that are able to pass through the mask materials to Zero,” commented Michael Rubinov, Kronos CEO.

About Kronos Advanced Technologies, Inc.

Kronos is focused on next-generation wellness consumer electronics products and PPE solutions. The Company was founded in 2002 and funded by the U.S. military to develop electrostatic air movers. Eventually, the Company moved into the consumer air purification business. It began operations as a product development company that invented and significantly changed the way air is moved, filtered, and sterilized. Historically, Kronos has focused on developing, marketing, and selling the Company’s proprietary air movement and purification technology. Serving the Indoor Air Quality (IAQ) market, Kronos technology uses state-of-the-art high voltage patented processes without the use of traditional porous HEPA filters. Kronos-based products move air silently, filter, sterilize, and purify the air while dramatically reducing energy consumption to half a 60-watt light bulb. Kronos devices can be variable in shape or size and, therefore, have the potential to be scaled-down for air purification in cars or scaled-up in size for industrial and hazardous gas destruction. The technology is currently being implemented in multiple standalone products for businesses, homes, and vehicles of all types to move, sterilize, and filter air, including removing allergens down to 14.6 nanometers by the passing of air through our patented technology. In addition, there are broad ranges of additional markets for standalone and embedded Kronos CORE technology-based devices. Immediately addressable markets are schools, universities, healthcare facilities, operating rooms, manufacturing clean rooms, and automobiles and commercial aircraft cabins.

The Company supports, which encourages people to make positive change while it helps others to breathe safe air by donating air purifiers locally and nationwide through campaigns that make an impact.

Kronos published research about the effectiveness of Kronos Patented technology on air disinfection n (e.g., microorganism destruction) by demonstrating the high efficacy of Kronos® Technology-based air purifiers in capturing and destroying various types of microorganisms (including Corona Viruses) in different environmental settings back in 2008. Results of this research showed that Electrostatic Air Filtration and Purification systems based on Kronos technology demonstrated high capturing and destruction efficiency for different types of microorganisms, bacteria, and viruses, and can be successfully used for disinfection of air in real word environmental settings, including hospital facilities both with and without the presence of people.

BusinessWeek called Kronos air purifiers “VIRUS KILLER” in 2005.

Kronos is the first publicly traded Company that accepts Dogecoin as a form of payment for its products, as well as other cryptocurrencies.

Recently, the Company filed for a provisional patent involving an innovative protective face mask with antimicrobial and anti-cellphone radiation protection features. The Company is planning to file additional patents to improve its existing technology as well as enter into new market segments but will continue to market air purifiers and other consumer products. The Company is an exclusive distributor and licensee of the latest generation of air purifiers based on the Company’s CORE technologies. The Company markets its products as Airdog® and KRONOS® brands. All Kronos products come with Kronos Promise -Your Satisfaction is Guaranteed!

Company offices are located in Parkersburg, WV.
