The air and surfaces around us are full of pathogens

Dangerous bacteria and viruses linger in the air and on surfaces in everyday spaces — from hospitals and classrooms to offices and locker rooms. Traditional cleaning methods leave gaps, and most air filters don’t neutralize what they trap.

The air and surfaces around us are full of pathogens

Dangerous bacteria and viruses linger in the air and on surfaces in everyday spaces — from hospitals and classrooms to offices and locker rooms. Traditional cleaning methods leave gaps, and most air filters don’t neutralize what they trap.

Conventional cleaning methods are not enough

Manual cleaning, HEPA filters, and chemical sprays have limitations — especially between cleanings. These legacy methods can’t continuously disinfect occupied spaces without disrupting people or workflows.

Visium Far UV for healthcare facilities

Drug-resistant pathogens pose an an ever-growing risk

Pathogens are only getting stronger. In particular, airborne transmission plays a major role in the spread of illnesses like COVID-19 and the flu. In healthcare environments, infection-causing pathogens linger on surfaces, creating a constant threat to patients.

Esherichia coli

Certain strains of E. coli can cause severe foodborne illness, kidney failure, or even death. It’s especially dangerous to young children, the elderly, and immunocompromised individuals, often spreading through contaminated food, water, or contact surfaces.

Staphylococcus aureus (MRSA)

MRSA is a drug-resistant superbug that causes serious skin, bloodstream, and surgical site infections. It’s highly contagious and difficult to treat, posing a major risk in healthcare settings. Infections can rapidly become life-threatening if not properly managed.

Respiratory syncytial virus (RSV)

RSV is a major cause of lower respiratory infections in infants, the elderly, and immunocompromised people. This virus can lead to bronchiolitis, pneumonia, and hospitalization, with serious outcomes in high-risk groups.

Human coronavirus

Human coronaviruses, including strains like SARS-CoV-2, can cause severe respiratory illness, pneumonia, and death. They spread rapidly through droplets and contaminated surfaces, with outbreaks leading to global health crises.

Influenza A (H1N1)

H1N1 is a widespread and highly contagious influenza virus capable of causing severe respiratory illness and global pandemics. It can lead to pneumonia, organ failure, or death, particularly in young children, the elderly, and those with weakened immune systems

Scientific Research

Visium Far-UVC fixtures kill or deactivate numerous pathogens, but all pathogens react differently to UVC light. Click here for our library of scientific papers about UVC light.

Norovirus surrogate

Norovirus surrogates mimic the behavior of highly contagious noroviruses, which cause intense vomiting, diarrhea, and dehydration. These viruses are extremely persistent on surfaces and require minimal exposure to infect, making them a leading cause of foodborne outbreaks.

Candida auris

Candida auris is a multidrug-resistant fungus that can cause deadly bloodstream infections. It spreads easily in hospitals, survives on surfaces for weeks, and resists standard disinfectants, posing a severe threat to vulnerable patients and healthcare infrastructure.
