The Solution to Pollutants

The Camfil Group is a world leader in the development and production of air filters and clean air solutions. We manufacture and supply products that satisfy all the demands at airports to control particulate and molecular pollutants. These products also satisfy the recommendations of EN13779.

The European standard EN 13779:2007 focuses on achieving a comfortable and healthy indoor environment in all seasons with acceptable installation and running costs. It is now a national standard in all countries. It specifies the required filter performance in a system to achieve good Indoor Air Quality (IAQ) taking into consideration the outdoor air.

The Solution to PollutantsVarious solutions are available depending on the extent of the pollution problem. Molecular filtration may be applied in either the fresh air make-up or recirculation air systems.

Solutions for makeup air are preferred since the principal sources of pollutant are external. These tend to be more heavy duty and reflect the high pollutant concentrations and one-pass operation. Solutions for recirculation applications reflect lower ambient concentrations and multi-pass operation. Continue reading

Misconceptions about air pollution – Air quality is better than it was

Founder & Director of Clean Air London, Simon Birkett recently wrote an article for Environmental Health News on the Misconceptions about air pollution.

The piece contains a series of cartoons which the campaign group Clean Air in London commissioned to address the capital’s environmental challenges. Beautifully crafted by Andy Davey (@DaveyCartoons), the cartoons address matters such as London smog, wood burning, the tube, cycling and taxis.

The first misconception mentioned within the article ’12 Misconceptions about air pollution’  is that ‘air quality is better than it was’.

Air quality is better than it wasThe Facts:
Visible coal smoke disappeared after the Clean Air Act and has been replaced by diesel exhaust and other largely invisible particles and gases. During this time, the certainty and scale of the health effects of air pollution have rocketed upwards while public understanding has remained where it was 30 years ago for smoking.

60 year anniversary for the Clean Air Act for City of London Corporation

Saturday 5th July will mark the 60th anniversary for the Clean Air Act which was put in place by the City of London Corporation to try and tackle the vast amount of air pollution.

The Clean Air Act is legislation that regulates how fuels are burnt in homes, commercial premises and smaller industrial operations.

Clean Air Act

It mainly focusses on the use of solid fuels, e.g. coal and wood. Implementation and enforcement of the Act is carried out by local authorities, this is the boroughs in London and district or unitary authorities elsewhere in England.

The Act introduced a number of measures to reduce air pollution, especially by introducing ‘smoke control areas’ in some towns and cities in which only smokeless fuels could be burned. By shifting homes’ sources of heat towards cleaner coals, electricity, and gas, it reduced the amount of smoke pollution and sulphur dioxide from household fires. Reinforcing these changes, the Act also included measures to relocate power stations away from cities, and for the height of some chimneys to be increased. The launch of the Clean Air Act was an important milestone in the development of a legal framework to protect the environment.

The Clean Air Act was introduced in response to the problem of coal smoke smogs, including the famous ‘Great Smog’ that caused the early deaths of 4,075 Londoners in 1952.

Air pollution in our biggest cities is much worse than most of us have realised.  It averages well over twice World Health Organisation (WHO) guidelines and legal limits near many of London’s busiest roads.  Mayor Johnson has estimated some 4,300 premature deaths in London in 2008 were attributable to long-term exposure to dangerous airborne particles alone.
