Delivering sustainable long-term Resilience, Confidence and Advantage


People spend most of their lives at home, but households can be the source of most illnesses due to the transmission of viruses between family members or occupants.

When microorganisms are brought into the home, they can become airborne when exhaled in a person’s breath or they can settle on clothing and other fabrics in the house. However, they can become airborne if they are disturbed after settling on a surface and some microorganisms, including COVID-19, are able to stay in the air for several hours if there is no effective air redistribution and disinfection system in place.

Older residential buildings

Older residential buildings struggle with the concentration of microbes, mainly as they only have limited ventilation rates, often from just windows (0.2-0.3ACH/window if conditions are correct), which are not always that effective at decontaminating the air in buildings. But nevertheless, windows are better than nothing.

Some old and larger types of residential buildings, such as care homes, have separate heating and cooling systems in place, which are only used intermittently. Others have recirculated HVAC systems that are pathogen spreaders rather than mitigators. This use pattern and lack of adequate ventilation lead to a greater concentration of microbes within older and communal residential building types, such as care homes. This explains why infections are rife across the sector.

  • Our solution: Upper Room GUV systems or Medical Grade HEPA Filter devices – Our active air disinfection systems will disrupt the stagnant air and disinfect and redistribute inert clean air in the home.

Newer residential buildings

Newer residential buildings often have air distribution systems built into them, but these systems often have limited air filtration installed in the system. This leads to a large number of microbes remaining airborne and being transmitted from one area to another.

  • Our solution: In-duct GUV devices in HVAC systems – Our technologies, when applied with a filtering system, are able to remove nearly all microbes from the air as they circulate through the air distribution system. Our technology can also disinfect or even sterilise key components of the air distribution systems, meaning that they do not harbour any harmful microbes.

Apartments and shared accommodation

Apartment type buildings can vary massively in terms of their size, occupancy, and many other factors, such as their ventilation systems.

Many apartments have their own individual air distribution systems, however, apartments can have high concentrations of microbes due to more people coming through hallways and sharing common areas and so, bringing potentially harmful microbes into the apartment building.

If apartments share a common HVAC system, infected air could be recirculated to other apartments. Therefore, each apartment needs to have its own air distribution and disinfection technology in place, in order to stop the transmission of harmful microbes around the building.

Our residential solutions

  • Better ventilation air flows, distribution and filtration.
  • In-duct GUV devices in HVAC systems – One way to counteract the spreading of disease is with efficient air circulation systems, which will be fitted with UV-C devices in order to kill any airborne microbes while the air is recirculated through it.
  • Upper Room GUV systems – these are ideal for buildings without a pre-existing HVAC system. These systems, when correctly specified, will be able to massively reduce the transmission rate of COVID-19.
  • Portable HEPA Filters & Medical Grade Filters – easy to use, “plug and play” devices that can be moved from room to room, if needs be.
