    • Improving your indoor air quality C L E A N A I R S O L U T I O N S Simon Birkett, Founder and Director, Clean Air in London www.cleanairinlondon.org www.twitter.com/CleanAirLondonClean air solutions
    • Lack of understanding C L E A N A I R S O L U T I O N S • Buildings may have mechanical ventilation, air conditioning and/or air filtration or none of these • Lack of understanding among senior managers and others • Few buildings comply with indoor air quality standard EN : 13779 – Some local authorities (LAs) in London have detailed information about their buildings – Other LAs do not know if their buildings comply – Many LAs do not know about compliance in their schools – Only eight of 15 TfL head office buildings by April 2012 • Significant opportunity to improve indoor air quality and reduce energy costsClean air solutions
    • Some practical issues C L E A N A I R S O L U T I O N S • Need gas filtration and two-stage particle filters in the most-polluted places • Gas filters vary in type, quality and efficiency • Glass fibre, bag filters can maintain performance and reduce energy loss because they provide a solid barrier and offer much higher surface air i.e. less resistance • Synthetic air filters may rely on electrostatic charge initially but lose their charge and efficiency over time • Ultraviolet light may tackle bugs but not particles or gases • Statutory requirement to inspect air conditioning systems at least every five yearsClean air solutions
    • Air filter groups and classes C L E A N A I R S O L U T I O N SGroup Filter class Example of use Average collection Average efficiency Average arrestance efficiency for the for 0.4 mm particles of dust % most penetrating % particle size (MPPS) %Coarse G4 Warehouses Over 90Medium M5 Protection of 40-59 ventilation systems M6 60-79Fine F7 Schools 80-89 (min 35) F8 Laboratories 90-94 (min 55) F9 Healthcare 95 and above (min 70)Efficiency particulate E10 Precision tooling 85filters E11 95 E12 99.5High efficiency H13 and H14 Operating theatres Over 99.95particulate filtersUltra low penetration U15, U16 and U17 Space craft Over 99.9995air filters Clean air solutions

    • Ask Camfil Farr for an ‘Opportunity Assessment’ C L E A N A I R S O L U T I O N S • Understand the system condition of your Air Handling Unit (AHU) • Request a report at no cost that proposes an itemised solution • Choose the best solution using low energy air filters • Give your existing AHU plant a new and efficient lease of life • Reduce running costs and get peace of mind Clean air solutions
    • Simple checklist C L E A N A I R S O L U T I O N S • Use easy access mountings and ensure seals are effective • Use low energy glass fibre bag filters, with high surface area, rather than synthetic or ultraviolet type filters to extend life and reduce energy cost • Use carbon filters to reduce gaseous pollutants • Consider upgrading fans as current ones may be energy inefficient • Clean cooling coils and heat exchangers • Clean air handling units and duct systems • Use pressure gauges to monitor ongoing filter efficiency • Regularly maintain the system and establish operating practices Ask Camfil Farr to certify your building as complying with EN 13779Clean air solutions
    • We can protect ourselves from air pollution C L E A N A I R S O L U T I O N Sfor up to 90% of the time If your office has a mechanical ventilation system or air conditioning (i.e. it is likely to contain the necessary ducting) please ask your employer: “Does our ventilation system include regularly maintained air filters that comply with European guideline EN 13779 and, if not, why not?” Any questions: visit www.camfilfarr.co.uk or call 01706 238 000 Photo of soot particles in air filter Photo: Lennart NilssonClean air solutions
    • 9 C L E A N A I R S O L U T I O N S Sustainable product range • Improved energy efficiency through product Life Cycle Assessment and product Eco-design • Our most energy efficient filters account for 60% of air filters for ventilation systems in buildings sales • Significant contribution to technical standards improvement : EN779:2012 now requires minimum efficiency for fine filters performance.Clean air solutions
