FAQs

While it has long been a question of when, and not if, a global pandemic would occur, the recent rapid spread of COVID-19 in our increasingly interconnected world caused global socio-economic and political unrest at an unprecedented scale. The economic cost exceeded several trillion dollars with unemployment rates not seen since the great depression. The reality of COVID-19, and fear of inevitable future outbreaks, have significantly heightened demand for new technologies for mitigating the spread of dangerous pathogens. Ultraviolet light can autonomously and continuously eradicate viruses, bacteria, fungi and allergens in occupied spaces, which is essential for containing and mitigating the [...]

Germicidal UV can be very useful in the HVAC ductwork to clean the coils and make them more efficient. However, the only air that can be cleaned in the ductwork is the air that actually circulates through it. Given the mechanical limitations of existing ductwork and the energy intensity of moving air through it, one might expect to achieve up to a few additional important equivalent air changes utilizing Germicidal UV in the ductwork. The advantage of in-room UVC like whole room Far UVC or Upper Room Germicidal UV is that it is cleaning the actual air in the room that [...]

Material limitations have historically prohibited LEDs from efficiently being able to create UV much below 260nm so there are no currently effective commercial Far UVC LED alternatives that we are aware of.  However, there are a handful of companies researching and developing Far UVC LEDs and we intend to integrate them into our products if/when they meet the performance and cost requirements for commercialization.

Since the wavelengths of UVC light are below the visible spectrum, it is unfortunately very difficult for an end-user without NIST calibrated equipment to visually tell the difference between 222nm (Far UVC), 254nm and 265nm lighting. The purple hue often emanating from UVC lights is typically from imperfections in the bulb glass.  We had actually researched and developed higher purity glass solutions which improved lamp efficiencies but ultimately decided not to commercialize them after customers indicated they preferred the light as an indicator that the fixture was on.

Germicidal UV lighting is not a cure for diseases already transmitted to humans and is not intended to be used for disinfecting people or equipment to be used in medical procedures on people. Instead, it is meant to sanitize the environments (air and surfaces) that people inhabit or come into contact with to prevent the risk of infection between people. As a result, Krypton and Lexus UVC lights are not medical devices and thus do not require FDA approval. Far UV Technologies is regulated and registered with the EPA under Establishment #96253-MO-1.  Far UV Technologies complies with all FIFRA labeling and [...]

MVP and MVP-Pro: 1 year Krypton 11 and Krypton 36: 3 years Krypton Guard and Krypton Shield: 1 year Legacy Guard: 90 days The limited warranty set forth below is given by Far UV Technologies, Inc. and applies to the Far UV Technologies fixture only.  The product when delivered to you in new condition in its original container is warranted against defects in materials and workmanship under normal use and service.  This does not include the bulb itself.  If the product is found to be defective during this warranty period Far UV Technologies will repair or exchange the unit for a new or refurbished [...]

Krypton Guard and Krypton Shield: 10,000 hours Krypton 11 and Krypton 36: 10,000 hours Upper Room Lexus Louvered and Lexus Open: 10,000 hours MVP and MVP-Pro: 5,000 hours Legacy Guard: 3,000 hours Most Kryptontm Far UVC bulbs or Lexus Upper Room GUV bulbs will last about 10,000 hours. As with any other light, you can extend the useful life in practice by simply turning it off whenever is not needed (either because the room is not occupied or if it no longer requires protection). A well-designed system will not only take into account product life but also disinfection* efficacy, safety, and [...]

Unfortunately, GUV bulbs are created with specialty lights that cannot be used with existing lighting fixtures or special adaptors. Far UV Technologies/AeroMed has over 30 years of experience in the design of reliable, efficient, and cost-effective GUV products and given the high degree of know-how needed to engineer and commercialize market-ready products and the importance for us and our component providers to provide effective solutions, we are not offering components for sale for integration into other products at this time.

Our most common commercial solutions are our Krypton-11 and Krypton-36 overhead or Lexus Upper Room lighting fixtures. They are largely set-it-and-forget-it solutions resembling oversized smoke detectors, which continuously and autonomously disinfect a given area of surfaces and/or the air above them. They would typically be installed in your highest traffic – highest risk often occupied areas. The Krypton-11 is best used with ceiling heights below 10 feet (3 meters) and the Krypton-36 is best utilized with ceiling heights 10+ feet. Lexus Upper Room GUV typically requires 9+ ceilings. The Krypton Shield is a compact collapsible mobile floor lamp that is about the size of a [...]

The area of coverage depends on your room dimensions, the user risk profile and the solutions chosen. The lights can provide protection for up to or over 1,000 square feet of space, more often targeting a higher degree of protection with 200-400 square feet per fixture. Even a single light can materially reduce the viral load of almost any space. As a result, GUV lighting can fit into most budgets. The higher the ceiling, the wider the coverage (but the weaker the light – think of shining a flashlight on a wall, and how the beam spreads and dissipates as you [...]
