Vystar Introduces New RxAir-800 Replacement Cartridge Extended Life UV-C Bulb

New RxAir400 Pro UV-C bulb replacement cartridge provides 18,000 vs 9,000 hr. use.

Worcester, MA, July 30, 2025 (GLOBE NEWSWIRE) -- With heightened concern about protection from harmful airborne viruses, Vystar Corporation鈥檚 (OTCQB: VYST)听 Germicidal Ultraviolet (UV-C) light air purification systems offers new features and options that will make it easier to treat airborne pathogens wherever you go indoors. RxAir400 is a smaller, consumer/small business-sized version of the industrial size Rx3000 FDA-certified Class II medical device UV light air purifier designed for disinfection use in hospitals. RxAir400 will now feature an ergonomic integrated handle for easier room-to-room portability, plus offer two new accessory options:

• Extended Life 18,000 Hour RxAir400 UV-C Pro bulb replacement cartridge - UV bulbs have limited life for germicidal effectiveness. RxAir units and bulb cartridges have interactive chips that communicate to alert users as the bulb approaches the end of life and needs to be replaced. RxAir 400 comes with its standard 9000 hr. UVC bulb cartridge good for approximately one year of regular use before requiring replacement. The new UVC Pro replacement cartridge has a lifespan of 18,000 hours, or approximately two years of normal use. Cartridges include free return and disposal of spent cartridges.
• Wall mount bracket 鈥� New low profile wall mount bracket makes it easier to put RxAir in an optimal location when traffic patterns and furniture layout are not conducive to floor placement. The low-profile bracket allows you to easily lift unit off the bracket to transport room to room to safely inactivate >99.9% of pathogens, reducing virus exposure risk in occupied facilities such as schools, restaurants, retail and offices.

Vystar鈥檚 new 18,000 hour cartridge is expected to be in stock in mid- to late Septmeber 鈥� just in time as students head back to school.

鈥淎 main advantage of RxAir is that it can operate safely in occupied spaces to continuously process the air up to eight times per hour, inactivating or killing the pathogens expelled as people talk, breathe, cough, sneeze or sing to help reduce risk of exposure for those in the room,鈥� stated Bryan Stone, MD, Internal Medicine and Nephrology. 鈥淲hen near people who aren鈥檛 wearing masks and may be asymptomatic, it is reassuring to have RxAir treating pathogens they may be expelling.鈥�

鈥淕iven the growing body of evidence that Coronavirus SARS CoV-2 may be transmitted through airborne means or aerosolization noted by the CDC^1,2, and hundreds of scientists worldwide^3,4,5, it is wise to address all modes of possible transmission,鈥� Dr. Stone noted. 鈥淲e strongly encourage people to wear face masks and follow other CDC recommended surface and personal disinfection practices, along with using RxAir to decrease their pathogen exposure risk as much as possible.鈥�

鈥淩xAir400鈥檚 ViraTech technology is one of the few UV light air purification technologies proven in EPA- and FDA-certified听 to inactivate more than 99.9% of airborne viruses (including multiple coronavirus strains), bacteria and other pathogens that cause pneumonia, influenza, MRSA (staph), streptococcus (strep throat), whooping cough, tuberculosis (TB), common cold, measles and a myriad of other antibiotic-resistant and viral infections,鈥� Dr. Stone explained. 鈥淗ospitals and healthcare facilities have been using ultraviolet germicidal irradiation (UVGI) with UV-C light for airborne infection control for decades because it is so effective. It also reduces concentration of volatile organic compounds and odors as well as air pollution linked to sleep disorders.鈥�

Air Purifier Demand Projected to Skyrocket

鈥檚 report in July 2020 stated, 鈥淭he enforcement of lockdown across the countries globally has led to the increased demand for air purifiers in the past couple of months. Moreover, as air purifiers are effective against various viruses, the demand in several countries is expected to witness significant growth owing to the outbreak of COVID-19. Few manufacturers are claiming that their air purifiers are an ideal option for neutralizing as well as effectively controlling the spread of coronavirus. In addition, consumers are buying air purifiers across the globe as a precautionary measure to mitigate indoor air pollution and to clean indoor air to avoid the novel coronavirus infection.鈥�

Grandview estimated that the global air purifier market size was USD $8.04 billion in 2019 and is expected to register a CAGR of 10.8% through 2027. Market Research firm Advisory & Intelligence is even more optimistic and is projecting that the global portable air purifier market will grow at a CAGR of around 42% between 2019-2025 to reach $90 billion by 2025 due to 鈥渆xponential rise in demand for clean air, owing to the rising population levels coupled with growing respiratory issue and epidemic spread across the globe鈥�

Jamie Rotman CEO of Vystar stated, 鈥渨ith 25,000 RXAIR units operating worldwide the demand for replacement cartridges has grown significantly. Residential users will change the cartridge annually, while commercial customers run the machines longer and require a cartridge change every six months providing a total market of 40,000 cartridge changes per year. The new extended life cartridge can cut that number in half, making production and sales more efficient for Vystar and the customer.鈥� The original cartridge will continue to be priced at $199 while the longer life cartridge will have some cost savings at $375. Vystar is only selling these cartridges directly or through a few select distributors like .鈥�
