FDA Greenlights Second Model in Kronos Advanced Technologies Inc.’s Revolutionary Air Purifiers Line


New FDA 510(k) Clearance for Model 8 Enhances Kronos’ Medical-Grade Air Purification Offerings, Expanding Deployment in Healthcare and Commercial Sectors

Los Angeles, CA , July 10, 2024 (GLOBE NEWSWIRE) — Los Angeles,CA  July 2024 (GLOBE NEWSWIRE)KRONOS ADVANCED TECHNOLOGIES, INC. (OTC MARKETS: KNOS) (“KNOS” or the “Company”), an innovation-driven product development company and creator of the patented Kronos® CORE air disinfection technology inside its advanced smart air purification devices, announced today that the U.S. Food and Drug Administration (FDA) has recently granted an additional 510(k) clearance to a flagship product, Kronos® Model 8, classifying it as a Class II Medical Device. This second FDA clearance was provided after a detailed review of the patented Model 5 device back in 2023, which utilizes patented High Voltage Field air disinfection technology proven to eliminate 99.9% of harmful airborne particles, including allergens, bacteria, fungi, and viruses, like COVID-19. This FDA clearance means our air purifiers can be deployed in hospitals and home healthcare settings to clear the air of infected bioaerosol droplets. Additionally, our products comply with all CARB regulations related to air cleaners for sale in California, and the Company’s manufacturer is registered with the State of California CARB.

Grand View Research: The global air purifier market size was estimated at USD 15.94 billion in 2023 and is expected to grow at a CAGR of 7.1% from 2024 to 2030, reaching approximately USD 25.58 billion by 2030.


Kronos can now provide schools, healthcare facilities, businesses, hotels, and government agencies with the best medical-grade air purification and air disinfection technology.

“As air quality concerns continue to rise globally, we are proud to announce that our manufacturer has been granted an additional FDA clearance for the Model 8 Air Purifier. We want to thank the FDA Team for their investigation and test results review of Kronos® CORE patented air disinfection technology,” said Greg Rubin, Interim CEO of Kronos. “We have been developing air disinfection and purification technology since 2002 and are experts in Indoor Air Quality. The recently approved FDA 510(k) clearance of the Model 8 device, powered by our patented Kronos® air disinfection technology, represents another major step forward in marketing our products to hospitals, doctors’ offices, allergy sufferers, and areas affected by natural disasters like wildfires.”

“There are only a few air purifier manufacturers on the market today that have received multiple 510(k) clearances, and this marks a significant milestone for our company and our shareholders. This certification validates the performance of the Kronos® Model 8 air disinfection technology capabilities as we prepare to manufacture our innovative products domestically and lead the air purification industry,” added Rubin.

The Model 5 and Model 8, which are our most popular models, have been rigorously tested in several credible international testing labs. Kronos® developed technology is an active filtration technology. Unlike other solutions, it generates a high voltage electric field to electrify and destroy harmful particles, collecting them on the uniquely designed, easy-to-wash collecting plates. Its 3 layers of washable filter technology equate to zero maintenance costs while eliminating up to 99.9% of harmful particles, 99.9% of PM 2.5, and 99% of chemical toxins in the air it cleans.

Traditional HEPA filter-based air filtration systems only capture larger particles such as dust or pet hair and require frequent filter changes to maintain effectiveness, drastically increasing system maintenance costs. Our technology can remove contaminants and allergens down to 14.6 nanometers (.0146 microns), which is 20 times smaller than HEPA filters – a definite market advantage.

As reported recently by CNN: A summer wave of COVID-19 has arrived in the US. COVID-19 levels have been rising in the United States for weeks as new variants drive what has become an annual summer surge. COVID-19 surveillance has been scaled back significantly since the US public health emergency ended more than a year ago — individual cases are no longer counted, and severe outcomes are based on representative samples of the population — but the data that is available is showing a consistent upward trend. Infections are probably growing in at least 38 states, according to data from the US Centers for Disease Control and Prevention. Wastewater surveillance suggests that viral activity is still relatively low, but hospitalizations and deaths are also ticking up. COVID-19 levels are especially high in the West, where viral levels are back to what they were in February, and in the South, according to the CDC. “The virus tends to replicate well and stay alive in an environment with warm and moist conditions. That fits with what we’re seeing,” said Dr. Robert Hopkins, medical director of the National Foundation for Infectious Diseases, a nonprofit public health organization. “The South and the West are steamy and hot right now.” The summer bump has become a familiar seasonal pattern, but experts warn that the coronavirus can still be quite unpredictable.

KNOS is committed to helping our customers, businesses, and government offices improve Indoor Air Quality (IAQ) and provide healthier and safer air.

Unlike any other air purifier on the market, Kronos® air purifiers use patented technology to do what other purifiers can’t — destroy airborne pollutants at the size 20 times smaller than conventional Hepa filters. These devices are the only FDA-cleared purifiers that use Kronos® technology and reach 99.98% efficiency in destroying airborne pollutants.

This additional FDA clearance comes as world health agencies increasingly recognize indoor air quality as a crucial factor in overall health and well-being. The EPA – Environmental Protection Agency has reported that indoor air can be two to five times more polluted than outdoor air, emphasizing the importance of effective air purification in homes and offices.

About Kronos Advanced Technologies Inc.

The Company was initially 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 how 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 of a 60-watt light bulb.

Kronos devices can vary 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, passing through our patented technology – replacing expensive outdated passive HEPA and other filtration-type systems. There are broad ranges of additional markets for standalone and embedded Kronos CORE technology-based devices. Examples of immediately addressable markets include schools, universities, healthcare facilities, operating rooms, manufacturing clean rooms, and the cabins of automobiles and commercial aircraft.

Kronos published research about the effectiveness of Kronos Patented technology on air disinfection (e.g., microorganism destruction) by demonstrating the high efficacy of Kronos® Technology-based air purifiers in capturing and destruction of various types of microorganisms (including Coronaviruses) 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-world 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!
