UV222™
Safe and Effective Far-UVC Lamp
The UV222 lamp offers a safe and effective solution for improving air and surface decontamination in various environments. It enhances indoor air quality by significantly reducing pathogens and is engineered to be safe for human presence during operation, providing a reliable option for maintaining stringent cleanliness standards across multiple facilities.
Far-UVC rapidly inactivates many common airborne and surface pathogens such as viruses, bacteria, mold, spores, fungi, and even antibiotic-resistant bacteria like MRSA.
UV222 harnesses this game-changing technology, offering a highly effective solution for surface and air disinfection. It can be used in all spaces and is safe to use in the presence of people, making it an essential tool to prevent the spread of existing and emerging viruses and other potential infections.

Introducing Mercury-Free Far-UVC Technology with KrCl Lamps
UV Medico is proud to introduce an advanced disinfection technology: mercury-free, 222 nm Krypton-Chloride (KrCl) excimer lamps. These innovative lamps offer a safe, sustainable alternative to traditional mercury-based systems, aligning with modern environmental and health standards. Ideal for cleanroom environments, KrCl lamps assure high-level disinfection efficacy without compromising human or ecological safety.
Combatting Mold with Advanced Far-UVC Solutions
Mold spores can compromise indoor air quality, triggering a range of health issues from severe allergic reactions to life-threatening infections, particularly in hospital environments. Our latest research reveals that intermittent, low-dose applications of UV222 are surprisingly effective in halting mold growth, ensuring cleaner air while maintaining safe environments for human presence. This innovative approach not only aligns with real-world usage but also opens new frontiers for maintaining health standards in medical facilities and beyond.
