10% of sunlight is made of Ultra Violet rays, of which only about 3-4% penetrate the atmosphere to reach the surface of the earth.

UV-C (100-380nm wavelength) has germicidal properties; 254nm is known to have the strongest germicidal effect. When absorbed by DNA and RNA in viruses and bacteria, UV-C deactivates them, rendering them unable to reproduce. The deactivated microbes are harmless.

UV-C (GERMICIDAL UV) >> 254nm is the MOST EFFECTIVE wavelength for sanitisation.

The OXIRA SENTRY, NOCTURNE and XN all work using the same technology – ultraviolet irradiation. Air is sucked into the unit, the ultraviolet light treats the air, and then expelled out.

With the SENTRY and NOCTURNE model, the UVC used is at 254nm wavelength, which deactivates the cells of viruses, bacteria, yeasts and fungi from the air.

With the XN model, the UVC used is at 185nm wavelength, which is also germicidal, but more importantly generates a steady stream of ozone which is effective in reducing odor by neutralising airborne bacteria, fungi, moulds and other substances such as VOC and formaldehyde.

The distance between the UVC source and the microbes are the determining factors of neutralization power, which is why OXIRA units are designed to be small so that the air passing through the OXIRA units will be at the closest range from the UVC light source for the most efficient neutralisation effect.

UV-C protects you, your family and friends, your staff and clients from pathogens and allergens, including viruses, bacteria and fungi (including mould and yeast).

UV-C rays have been scientifically proven to effectively kill 99.99% of the above microbes. This can effectively reduce airborne transmission of pathogens such as influenza, measles, coronavirus, chickenpox, tuberculosis, and triggers of asthma or airborne allergies.

We use one of the most powerful and reliable UV tubes available in the global market. We have partnered with leading German company to bring you the world’s best quartz lamps. Each OXIRA unit contains one UV tube which has operation life of 15,000 hours. 15,000 hours is equivalent to 20 months of continuous 24/7 operation, or 41 months if operated 12 hours a day.

Moulds are fungus and are very common in humid regions like Hong Kong… especially in outdoor air.

UV-C and ozone are both very efficient in killing… and how tough they are. All OXIRA models are efficient in reducing moulds but XN is relatively more efficient because it generates ozone which will actively spread to even the darkest corners to attack the mould fungus.

OXIRA is one of the very few UV-C Air Neutralizers that are laboratory proven worldwide to effectively reduce 99.99% of airborne coronavirus.

You can expect higher performance with the use of 254nm UV-C and its special reflector coating that boosts UV-C intensity by over 50%.

OXIRA units have been designed specifically for the healthcare industry where safety, simplicity and durability are of paramount importance.

Global Lab test results have shown that the OXIRA unit complies with international safety standards and is SAFE to use.

OXIRA Certifications

OXIRA’s airflow is NOT ADJUSTABLE because it is preset at an air flow speed for OPTIMUM UV-C EXPOSURE to ensure the most effective killing of airborne pathogens in a single passing.

Only the XN model generates Ozone. The amount of ozone produced by the XN model is significantly low meeting international safety standards that give customers peace of mind.

The XN model has two actions: It kills germs and deodorises the air without any chemicals. It is extremely safe to use.

The Nocturne and Sentry models do not generate any ozone.

Most odours in our daily lives are generated from bacteria and moulds. OXIRA’s germicidal power will remove such odours.

OXIRA is most effective if placed close to person or the crowd you intend to protect for close range protection. OXIRA units are designed small so that you could distribute multiple units in business premises for simultaneous protection at different spots of the room. Adequate internal air circulation will also help ensure the performance of OXIRA units. Doctors around the world understand that face masks cannot completely block the tiniest virus particles such as coronavirus and influenza, which is why doctors usually place OXIRA on the desk between them and their patients, so that OXIRA can provide them with continuous and close range protection. As OXIRA can be powered by powerpacks since late 2021, OXIRA has probably become the world’s only professional portable air purifier. You can bring your own OXIRA unit and place it on the dining table when you dine out or when you take a long-haul trip for your most effective protection.
