Why the Use of UVC Germicidal

Why UVC Germicidal

Watch the video for a quick summary of the effectiveness of UVC disinfection lamps.

Basic principles are:

The law of convection moves air from the lower half of the room to the upper half over 20 air exchanges.

A UVC germicidal lamp is placed at ceiling height and emits a narrow band of light that covers the entire ceiling, capturing 100% of the air.

Its patented design ensures that no UVC light is directed downwards, allowing normal activities to take place.

Why our UVC Luminaires are Safe

LABORATORY UV FILTERS

Through our patented design, our prism and louvre ensure that a narrow beam of UVC light is safely emitted, covering the entire ceiling.

No light is emitted downwards from the ceiling.

Tested at the Institute for Light Science and Technology

University of Pretoria, South Africa

UVC LIGHT

99.9% effective in breaking down the DNA & RNA of Viruses and Bacteria

AIR CYCLE

Over 20 air cycles per hour moving from lower half to the upper half - through law of convection

AIR CAPTURED

100% of the air is captured as the air moves upwards to ceiling height

SAFE

Placed at ceiling height a narrow band of light is emitted, with no light shines downwards

ECONOMICAL

Rooms normal HVAC systems can function providing hot and cool air that does not escape, that saves energy

Some Common Question about UVC

Listed below are some of the answers provided in the use

of UVC Germicidal Luminaires

How does UVC light kill or inactivate germs in the air?

UVC light penetrates the cell walls of microorganisms and disrupts their genetic material, preventing them from reproducing or functioning. This renders them harmless and effectively inactivates pathogens in the air that could otherwise cause illness

What types of pathogens can UVC air purification eliminate?

UVC germicidal systems are effective against a wide range of airborne microorganisms, including: Viruses (e.g., influenza, SARS-CoV-2) Bacteria (e.g., E. coli, tuberculosis) Mold spores and fungi This makes them especially valuable in healthcare, commercial, and residential environments.

What is UVC germicidal technology in air purification?

UVC germicidal technology uses ultraviolet light at a wavelength of 254 nanometers (UVC) to destroy the DNA or RNA of microorganisms like bacteria, viruses, and mold spores. When installed in air purifiers, UVC lamps help neutralize airborne pathogens as air passes through the system.
Do UVC air purifiers require maintenance or replacement parts?

Yes, UVC lamps lose intensity over time, even if they still light up. Most manufacturers recommend replacing UVC bulbs every 9 to 12 months to ensure optimal germicidal performance. Regular cleaning of the air purifier’s internal components also helps maintain efficiency.
Is UVC air purification safe for humans and pets?

Yes, when properly enclosed within an air purification system, UVC light is safe. The UVC lamps are typically shielded so that the radiation doesn’t escape into the living space, eliminating any risk of skin or eye exposure.
Can UVC light eliminate the COVID-19 virus from the air?

Yes, studies have shown that UVC light can inactivate SARS-CoV-2, the virus that causes COVID-19. UVC radiation disrupts the virus's RNA, preventing it from replicating and causing infection. When used in air purification systems, UVC light helps reduce airborne viral load, lowering the risk of transmission.
Does UVC work instantly to kill viruses and bacteria in the air?

UVC light begins working immediately upon exposure, but its effectiveness depends on exposure time, light intensity, and air speed. In air purification systems, the air is typically exposed to UVC light long enough to achieve high kill rates of viruses and bacteria in a single pass.
How effective is UVC in killing airborne bacteria?

UVC is highly effective at destroying a broad range of airborne bacteria, including Staphylococcus aureus, E. coli, and Mycobacterium tuberculosis. It damages bacterial DNA, making them non-viable and unable to reproduce, which prevents infections from spreading through the air.
Is UVC germicidal technology proven and safe for long-term use in occupied spaces?

Yes, when used in sealed or ducted air purification systems, UVC light is safe and proven for continuous operation in occupied areas. The germicidal light stays contained inside the unit, ensuring people are not exposed to harmful UV radiation while still benefiting from cleaner, pathogen-reduced air.
Is UVC a substitute for other COVID-19 prevention methods?

No, UVC is an additional layer of protection, not a replacement. While it helps reduce airborne virus particles, it should be used alongside other safety measures like ventilation, hand hygiene, and masking—especially in shared or high-risk indoor spaces.
