A recent publication from King’s College London and the UK Health Alliance has revealed that…
“Seven in 10 hospitals and health centres are in inner London areas blighted by illegal levels of toxic air”
The analysis found that 577 of these establishments were in areas where nitrogen dioxide levels breached EU guidelines. In addition, all 800 facilities were in areas where the pm10 particulate matter was above the World Health Organisation limit.
This toxic air seeps into hospitals and healthcare facilities, as the biggest contributor to inside air pollution is outside air pollution. Outside air is polluted by vehicle emissions, power generation and tobacco smoke. These harmful pollutants seep into buildings through windows, doors and other permeable areas.
Ventilation and air conditioning equipment used in many commercial properties bring ‘fresh air’ into the building. However, the pollution levels mean the outside air is not always ‘fresh’.
In order to ensure harmful pollutants are not brought inside the building, there is a need for the air to be filtered first. Highly polluted areas such as London and other large cities will require higher grade filtration, which may need to be cleaned or replaced more frequently.
Indoor air quality can be significantly improved by introducing a heating, ventilation and air conditioning (HVAC) system that has built in high efficiency air purification. Advanced air purification systems, such as The Ingenious® Air High Efficiency Purification System, will use a combination of technologies to:
- Remove up to 96.3% of microscopic particles and airborne allergens as small as 0.3 microns.
- Destroy airborne bacteria, viruses and volatile organic compounds (VOCs).
- Reduce VOC chemical fumes and odours by up to 90% or more.
