Visium Far-UVC: How it Compares
Visium Far-UVC vs. Hepa Filters
HEPA filtration is a net. It captures particles that can carry bacteria and viruses, but only the ones that float into the filter. Visium Far-UVC uses a specific wavelength of ultraviolet light (222 nanometers) that continuously inactivates bacteria and viruses the instant they float through the air — across the entire room, all the time, without anyone having to do anything.
Visium Far-UVC Technology is a continuous biosecurity system that silently kills airborne germs using a special wavelength of light — while people are still in the room.
Visium Far-UVC vs. Traditional HVAC Filtration
Your HVAC system pulls air through a filter — but only the air that actually makes it to the filter gets cleaned. Imagine a crowded classroom: one kid sneezes near the window, far from any air vent. That virus-laden air can float in the breathing zone for minutes before the HVAC system ever touches it.
Visium Far-UVC fixtures sit at the ceiling and fill the whole room with a field of light that inactivates pathogens the instant they’re in the air — no waiting, no dead zones.
Visium Far-UVC vs. Traditional 254nm UVC
You’ve probably heard that UV light inactivates viruses and bacteria — that’s been true for over 100 years. The problem was it also could hurt people’s eyes and skin, so it was only used in empty rooms or unoccupied spaces.
Visium figured out how to use a specific wavelength — 222nm — that destroys viruses and bacteria but physically cannot reach the living cells in your eyes or skin. Same germ-killing power. Safe for occupied spaces. That’s the entire difference.
Visium Far-UVC vs. Portable Air Purifiers
A portable air purifier is like a vacuum for germs: it sucks in nearby air, filters it, and blows it back out. That works — but only for air that actually passes through it. The other side of the room, the corner by the window, the air someone just exhaled two feet from the purifier — none of that gets treated until it happens to drift toward the machine.
Visium mounts at the ceiling and uses light to inactivate pathogens throughout the entire room simultaneously. No spot-treatment. No dead zones. No noise.
Visium Far-UVC vs. Upper Room UVC Devices
Upper-room germicidal UV has been used since the 1930s. It works by shooting germicidal UV light upward toward the ceiling where it can’t reach people’s eyes. Air rises up through that zone, gets cleaned, and falls back down. Smart — but it depends on air actually moving up and down. Low ceilings, air conditioning, or bad airflow and the whole system underperforms.
Visium Far-UVC uses a different wavelength that’s safe for the entire room — not just the upper zone. The light goes everywhere. People can be anywhere.
