We have published an informative White Paper highlighting the opportunities that arise from choosing effective air filtration systems within non-domestic buildings. To find out how the indoor air quality within your organisation can be improved whilst delivering significant energy savings, download the White Paper here.
Many multi-site organisations and Estates Departments at larger organisations are committed to developing and implementing energy plans, involving strategy and policy on energy and sustainability. One of the main aims of these plans is to strive to balance the key principles, those of sustainability, financial viability, environmental enhancement and social responsibility.
We can demonstrate through a number of high profile installations, how air filters directly influence energy consumption within air handling units that heat, cool and clean the air of approximately 200,000 air conditioned buildings in the UK.
The White Paper, called ‘Quick wins for energy savings in buildings: Choosing low energy air filters for both optimised energy performance and indoor air quality’ addresses the challenge that all industry sectors are facing when it comes to the energy efficiency of their building stock.
The Federation of European Heating, Ventilating and Air-Conditioning Associations have estimated that within the EU alone there is a potential annual saving of 5TWh available by switching to Low Energy Air Filters. This would equate up to £500 million energy saving in the UK.

Another European EU funded study confirms that previous WHO air pollution limits set for PM2.5 and related Nitrogen dioxode NO2 are too high and now need to be lowered for health reasons.
This latest study led by Dr Rob Beelen, from Utrecht University in the Netherlands estimates that for every increase of 5 micrograms per cubic metre in annual exposure to fine-particle air pollution PM2.5, the risk of dying from resulting exposure rises by 7%. PM2.5 stands for particulate matter 2.5 microns and below in size and is usually comprised almost entirely of toxic traffic emissions.
In large cities such as London the annual mean values for PM2.5 are typically in the range 15 to 25 micrograms per cubic metre and sometimes even more at busy road junctions. Simple arithmetic indicates increased risk of dying at 14% to 28% above a base level of 5 micrograms per cubic metre.
The world health organisation says there is no safe level of exposure to PM2.5 pollution. Exposure results in raised levels of heart and lung disease in the population.
The Kings College air quality website now has an interactive website that enables anybody living in London to enter their work or home post code and get a personal colour coded map to show annual levels of PM2.5 fine combustion particulates and associated gas phase pollution such as Nitrogen Dioxide. An example is shown below for the City area of London.

Post written by Dr Chris Ecob, Global Business Manager for Molecular Filtration, Camfil Group:
The leading organisation responsible for cataloguing chemicals – the CAS Registry (Chemical Abstract Service) – has more than 73 million unique chemicals in their database and is adding new items at the rate of 15,000 every day. Many of these chemicals never pre-existed in nature and have been created by man in the industrial era. Some chemicals only exist as gases in the air.
However, all chemicals, including those that are normally liquids or solids, have to varying degrees the ability to evaporate and become airborne in their molecular form. It is an inescapable fact therefore that all around the globe, there are more chemicals in the air than ever before.
Categorising molecules by impact
Airborne molecules may be categorised according to their impact on humans and our world. Responsibility for smell or odour is perhaps the most obvious.
The receptor cells in the nose and the human brain are capable of detecting and characterising many different odour types. Some molecules are classified as irritants. In addition to creating an odour response, they stimulate an involuntary and negative reaction from the body. The classic example is activation of the tear ducts when chopping onions. Continue reading
