Fresh Air and OXIRA

 

Fresh air

The government and leading experts have highlighted the importance of fresh air as a defence against Covid 19 and airborne transmission of diseases.   Ongoing research into how Coronavirus spreads found that although distancing measures were a good first defence, the aerosol generated from various activities could travel further than first thought. This makes airborne transmission increasingly likely, especially in places with poor ventilation.

It is therefore important to have either good ventilation or a system that can provide continuous air disinfection, particularly in places of your practice that don’t have windows that can be opened to provide a good standard of ventilation.

There are several factors that make open windows as a source of ventilation not an option such as No windows to open, security, external noise and for the UK, the weather.  With increasing cost of heating, you do not want to be letting out of an open window.

There are a number of systems on the market that can filter the air of pathogens, but there are a few points that you should consider when making your purchase.

For example,

  • does the air disinfection unit have the scientific evidence to prove the product kills and deactivates all airborne pathogens?

The OXIRA is surported with 10 years of scentific validations from leading international Universities and test intutites, confirming 99.9% deactivation of not only Covid 19 but also full kill of bactira, molds and fungus.  The OXIRA has been validated inaccordance with international electrical safety and EMC

  • Can the system be used 24/7 around even the most vulnerable?

The OXIRA is designed to run on a 12v 18w power supply.  The electronics are designed to ensure that the unit can be run continuously without the risk of overheating. The low energy 12v power supply is provided with the unit to allow straight out of the box use. Both the OXIRA and the power supply are CE marked and meet the requirement for UKCA certification.

  • Can it be used and installed at ease, if any maintenance is required and whether the system is advanced enough to filter out odours from the air.

The OXIRA takes air from the room within your personal space. Passes it over a UVC Quartz Vapour Lamp of the highest quality and maximum output. The treated air is then exhausted on a plume that can reach upto 1m, dispersing the untreated air and giving a germ free zone.  It is simply plugged in directly from the box.  It is supplied with a combination stand and wall bracket so it can either be mounted on the wall or sit on a desk or counter.  The design is so compact it can fit in to a laptop bag to give protection on the more.

The OXIRA come in two families, with or without odour reduction.  The odour reduction is conducted by the generation of ozone, this gives the germicide effect of the standard unit with the additional ozone odour reduction.

The OXIRA is design to be low maintenance, the only moving part is the fan which is rated at 24month continuous use. The lamp has an optimal life of 1500hrs.  The service option allows for the to be return or exchanged following 12 months or 1200hrs to ensure maximum effectiveness.

The OXIRA are sold in over 62 countries and have been estbhished in Asia and South Americ for more then 10 years as tool to help reduce the spread of SARs, TB and Covid 19 in healthcare, hotels and offices, as well as in domsitic settings.  .

Government Guideline https://www.gov.uk/government/publications/covid-19-ventilation-of-indoor-spaces-to-stop-the-spread-of-coronavirus/ventilation-of-indoor-spaces-to-stop-the-spread-of-coronavirus-covid-19  recommend Mechanical ventilation in the home

“If your home has a mechanical ventilation system, make sure this is working and maintained in line with manufacturers’ instructions.  Set ventilation systems to bring fresh air in and not recirculate indoor air. Devices that only recirculate indoor air will not remove airborne virus from the home. You can use the boost mode (if available) to increase ventilation if someone in your household is self-isolating due to COVID-19 or if you meet people you do not live with indoors. Ventilation can also be increased by leaving extractor fans in bathrooms, toilets and kitchen areas running for longer than usual, with the door closed, after someone has been in the room.”

Such air ventilation system are large , high cost and require installation and maintenance. In many residential settings are impractical.  Bring air in from the outside, not only increases outside pollution but brings in cold air and decreasing the temperature of the house, not idea in the winter and ever-increasing heating bills.  The OXIRA takes the air within the room and removes the airborne virus and germs. By treating the air within the room, it reduces the airborne , whilst not affecting the heating.  Once the air has been treated it feels fresh and has not only covid removed but also the common cold, mold and fungus such as white and black mold.

The units are quite and the compact design allows them to positioned in any location and any room including the bedroom.

 

Ventilation in the workplace and non-domestic settings

Ventilation should be considered alongside other control measures to reduce the risk of COVID-19 transmission within your workplace or public indoor space. It is important to identify and deal with areas that are not well ventilated. The more people occupying an area that is poorly ventilated, and the longer they remain in it, the greater the risk of spread of COVID-19.  Control measures such as avoiding certain activities or gatherings, restricting or reducing the duration of activities, providing ventilation breaks during or between room usage should be considered alongside ventilation for reducing the risk of airborne transmission.

Any actions to improve ventilation should not compromise other aspects of safety and security (for example, avoid propping open fire doors), and should consider other consequences such as health and wellbeing impacts from thermal discomfort.

The OXIRA allows for each desk or workstation to have its own personal space of germ-free air. The compact design can easily fit any desk or work space.  By having more than one units, the overall infection risk for the complete office will be reduced.  Wall mounted OXIRA in the corners of the room, or booths ensure that all areas are treated.  It has been shown that the OXIRA increase the wellbeing of the complete office, reducing the risk of covid and other airborne infections such as the common cold.

The Health and Safety Executive provides advice on working safely and ventilation and air conditioning.

Make sure mechanical ventilation systems are maintained in line with manufacturers’ instructions. Set ventilation systems to using a fresh air supply and not recirculating indoor air, where possible. Assessing the requirement and performance of ventilation systems in many environments requires engineering expertise. In addition, ventilation design may be specific to the setting. For some existing and older buildings, ventilation systems may not have been designed to meet current standards and additional mitigations may be needed. If you are unsure, seek the advice of your heating, ventilation and air conditioning (HVAC) engineer or adviser.

Detailed ventilation guidance for workplaces and public buildings during the pandemic is provided by the Chartered Institution of Building Services Engineers (CIBSE).

 

In many builds and office fresh air drawn in from out side is not possible.  Air conditioning units have the added risk of fungus and molds and worst case airborne infections such a legionnaires design, if not maintained.  The OXIRA treat the air without any chemical or water based cooling , therefore reduce the risk of adding the infection rate within the office.  The human traffic of staff opening and closing doors enable the air movement without the need of external forced air. The OXIRA can be used in any environment or age of building that has a mains power supply.  The Ozone units can be used to reduce odours and mold freshening up stale air.

Ventilation in vehicles

Like buildings, enclosed vehicles including cars, vans, and buses can also be high-risk for spreading COVID-19. It is important that vehicles are well ventilated to help reduce the risk of spreading COVID-19.

When operating or travelling in vehicles:

  • switch ventilation systems on while people are in the vehicle – set to drawing fresh air in, not recirculating air
  • to improve ventilation, windows can also be opened (partially if it’s cold) – heating can be left on to keep the vehicle warm
  • for vehicles that carry different passengers, such as taxis, clear the air between different passengers or at the journey end so the vehicle is aired before anyone else gets in
  • opening doors where it is safe to do so will help to change the air quickly – opening windows fully can also help to clear the air in the vehicle

Further guidance on safer transport for operators and taxis and private hire vehicles is available. The Health and Safety Executive also has advice on ventilation in vehicles.

 

The government guidelines suggest open windows and drawing air from outside the vehicle.  It also suggests that the air should be clear between passengers. This is not always practical, especially for a busy taxi driver. The OXIRA can run via the 12v supply within the vehicle via the cigarette lighter or hardwired. By having the OXIRA running it treats the air, continuously reducing the risk for both driver and passenger.  With the added advantage of not needing to have open windows and giving a fresh air feel within the vehicle with increasing the pollution from outside.

Balancing ventilation with keeping workplace temperatures comfortable

Providing adequate ventilation does not mean people have to work in an uncomfortably chilly or cold workplace.

There are simple steps you can take to make sure your workplace is adequately ventilated without being too cold:

  • windows and doors partially open can still provide acceptable ventilation while keeping the workplace comfortable. Opening higher-level windows will probably create fewer draughts.
  • if the area is cold you could relax dress codes so people can wear extra layers and warmer clothing

You should only use fan convector heaters if the area is well ventilated.

The government guidelines suggest the best approach to reduce the risk of covid inside is open the windows, and if it is cold wear more cloths, if the covid does not get you high heating bills and hypothermia may.

The OXIRA does not require open windows, wearing etc cloths or turning up the heating.  It takes the air in your room and makes it safe.  The OXIRA is quite enough to have running in a bedroom or next to your chair in your sitting room or office.  The 12v power supply ensures minimal running costs.
