NO.1 EUSTON SQUARE, LONDON –AIR QUALITY CASE STUDYTHIS CASE STUDY LOOKS AT THE AIR QUALITY BEING EXPERIENCED ON A DAILY BASIS IN LONDON BY PEOPLE WORKING AND TRAVELLING ABOUT LONDON.
It looks at how a combination of a standalone CamCleaner City air purifier, effective air filtration and a well sealed building envelope can deliver clean, healthy, Indoor Air Quality.
In general terms the main health hazard comes from exposure to traffic pollution. Fine combustion particles and gases in a toxic mix that can be inhaled by people and are classed as a Group1 (highest level) carcinogen by the World Health Organisation.
No:1 Euston Square, London is close to Euston station it is good for business and transport links of all types. Unfortunately transport such as trains buses and taxis produce this air pollution.
There are other outside sources such as the much publicised recent southern UK air pollution incident involving desert dust and also volcanic events causing disruption to air transport because of airborne particles.
Clearly these fine particles can sometimes travel in concentrated plumes over long distances and stay airborne almost indefinitely. This also applies to traffic air pollution particles and gases thatcan stay in the air and react producing chemical smog.

CAMCLEANER CITY
Local sourced city air pollution from traffic, in the City of London for example, is classed as PM2.5 combustion particulate and the accompanying gas Nitrogen dioxide NO2 pose the main health threat to people living and working in London unless they smoke.
These two pollutants go together and high PM2.5 concentrations in areas with traffic inevitably means high levels of NO2 and the Euston Road near the station is one of the most traffic laden and therefore polluted roads in London. It was decided to measure airborne particle levels in key locations such as in the office, in the associated corridor outside the office, and close to the main entrance of the office building. The results show the particulate air pollution level was measured at in the range 0.3 to 0.5 microns dia. which is a particle size range that can easily make deep lung penetration and cause health problems.
One this day the outdoor particle concentration level as can be seen by the red curve in Graph 1 was mainly in the range 80 - 90 million particles per m3 of air which is about over a twenty times higher concentration than the 3 - 5 million particles that would be expected in the air in a cleaner rural village location outside London. Clearly the air in our cities can no longer to assumed to be clean and healthy.
The beneficial effects of a well sealed building envelope and effective air filtration in the air conditioning system can be seen from the results of the red curve in graph 2 above. Further reductions were made shown by the blue curve (measured from the centre of the room) down from value of about 12.5 million particles per m3 reducing by almost half (44%) down to about 7 million particles per m3 in the office with people present during test. This was achieved by use of a standalone air purifier known as the CamCleaner City. The air is constantly being cleaned so it

THE RESULTS IN GRAPH 1 SHOW THE PARTICULATE AIR POLLUTION LEVEL WAS MEASURED AT IN THE RANGE 0.3 TO 0.5 MICRONS DIA. WHICH IS A PARTICLE SIZE RANGE THAT CAN EASILY MAKE DEEP LUNG PENETRATION AND CAUSE HEALTH PROBLEMS.

feels better to breathe and no longer has health issues.This air purifier is inconspicuous and effective. It runs quietly in the background and recirculates the clean purified air with almost silent running performance that consumes little energy. The green curve in Graph2 shows that close to the CamCleaner City particles are almost totally removed from the air.
This unit also contains high efficiency molecular gas filtration that can remove NO2 and a range of indoor sourced air gas pollutants. This is a solution that delivers clean purified air at point of need and can be used in a residential or home office application as well as commercial settings.
Camfil offers a structured and logical range of solutions to deliver Clean Healthy Indoor Air Quality including the City check IAQ test kit for indoor gases. Find out more and see case studies on:
