Airocide GCS-25 UVC air purification system. Retail price €3,965. Very effective — stops sniffles, Kankaanpää

The Airocide GCS-25 UVC air purification system uses technology developed by NASA. It employs a reaction chamber filled with small catalysts and UV lamps that, by stimulating a highly reactive surface, split water molecules and form a surface-bound hydroxyl radical.

As a result, all micro-organisms that come into contact with the Airocide GCS-25 UVC system are oxidised immediately. It not only radically removes ethylene gas, but has also been clinically proven to destroy volatile organic compounds (VOCs), viruses, bacteria, fungi, mould, whole-grain dust and carbon.

The Airocide GCS-25 UVC system is widely used in homes, properties, businesses, food storage facilities and healthcare settings. It is also classed by the FDA as a Class II, Class B medical device.

The Airocide GCS-25 UVC air purification system is an industrial solution for fresh air in even the most demanding environments. It can be used in hospitals, healthcare facilities, diagnostic centres, private clinics, patient waiting areas, intensive care units (ICUs), etc., where air is required to be as free as possible from pathogenic micro-organisms.

It is well known that hospital areas such as intensive care units (ICUs), operating theatres, transplant units, haematology wards, etc., have special requirements for sterile air with minimal bacteria. This is achieved by the Airocide system technology, which reduces airborne microbial load (bacteria, viruses, fungi).

Additionally, on-site air sterilisation is needed for wineries (keeps winery mould away without chemicals), vegetable, fruit and flower storage (keeps ethylene to a minimum, slowing ripening) and gyms (neutralises organic matter and reduces unpleasant odours).

Airocide GCS-25 specifications: Air purification capacity: 34 m³/h Length: 465 mm Width: 525 mm Depth: 115 mm Weight: 8.34 kg Noise: 42 dB Voltage: 100–240 V AC Current: 1.0 A Frequency: 50/60 Hz Power: 73 W Colour: White Maximum room area: 85 m² External material: Thermoset plastic

Airocide GCS-25 UVC operation: All Airocide UVC air purification system variants operate photocatalytically without filters, so there are no filters to replace. The device irradiates a surface coated with a titanium dioxide catalyst with UV light, which stimulates water vapour molecules in the air and splits them into OH• and H+ ions. These highly reactive ions oxidise all organic matter in their vicinity. All this occurs within the device’s reaction chamber so that free radicals do not endanger people around the unit in a fully enclosed space. Airocide GCS-25 UVC sterilises at: 34 m³/h

A new, unopened unit costs about €4,000 online.
