Understanding EN13779 and how to improve your indoor air quality – Presentation

A recent report by Campaign for Clean Air in London (CAL) highlighted the lack of understanding among senior managers and others that few buildings comply with indoor air quality standard EN: 13779.  Buildings may have mechanical ventilation, air conditioning and/or air filtration or none of these and few buildings comply with indoor air quality standard EN:13779.


In London for example many Local Authorities do not know if their buildings comply and many Local Authorities do not know about compliance in their schools and that significant opportunity exists to improve indoor air quality and reduce energy costs.

So what can I do?

Ask Camfil Farr for an ‘Opportunity Assessment’ this will help you:

  • 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

Follow this simple checklist:

  • 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 on-going filter efficiency
  • Regularly maintain the system and establish operating practices

 Finally you should ask Camfil Farr to certify your building as complying with EN 13779.

New high-tech centre in Sweden enhances Camfil Farr’s global R&D capability

In Sweden, we recently inaugurated one of the largest R&D centres in the world for the development of air filters, clean air solutions and filter production technology.  The new facility – the Tech Centre – is located 70 km south of Stockholm in the Baltic coastal town of Trosa.

Simon Birkett (center) founder and Director of Clean Air in London takes a closer look at one of the test rigs during the guided tour. From the left David Moulton (Camfil UK), Isto Salonen (Camfil Finland) and Peter Dyment (Camfil UK) to the right.

The centre develops products with the latest laboratory and research equipment to meet a growing global need for air filtration solutions that safeguard health, satisfy stricter energy efficiency and sustainability standards, and meet emerging needs for high-tech filtration using the latest nano-fibre technology. The latter includes researching new polymer technology for developing new and more effective filter material, including hybrid media. Air filtration experts at the centre also analyse air quality and how it impacts human health and production processes.

The opening ceremony in Trosa, held in late October, was hosted by Anders Freyschuss, Managing Director of Camfil Sweden and Anders Sundvik, Camfil Farr’s Vice President for R&D. Per Westerberg, Speaker of the Swedish Riksdag, inaugurated the centre. Camfil Farr’s Road Show trailer was also on location in Trosa for the event. This unique travelling mobile lab and exhibition has been touring Europe to spread knowledge about the importance of filtration and filters, and the benefits for IAQ and health – all in line with Camfil Farr’s vision to make clean air a human right.

New report reveals ignorance over indoor air quality in public buildings

Air filtration in public buildings in London –   Many local authorities are in the dark when it comes to knowing if their buildings use regularly maintained air filters that comply with indoor air quality standard EN 13779, particularly schools, according to a new report from Clean Air in London (CAL).

Indoor Air Quality in Offices

In the report, the cross-party campaigning group claims that indoor air quality (IAQ) can often be worse than outdoor (or ambient) air quality, due to the many sources of pollution that exist within buildings and homes. CAL is therefore campaigning to build public understanding of indoor air quality, initially in London, with support from us here at Camfil Farr.

The report examines the issue of air filtration in public buildings in London.  It includes the results of an Environment Information Regulations request to local, regional and central Government bodies asking ‘which buildings owned, occupied or managed by the Local Authority use regularly maintained air filters that comply fully with European guideline EN 13779 e.g. offices and schools’.  The responses received are analysed and ranked.

The Greater London Authority Group (GLA Group) demonstrated detailed knowledge of its buildings.  However, CAL was surprised to discover that only eight of 15 buildings in Transport for London’s ‘Head Office Portfolio’ were due to comply fully with EN 13779 by April 2012 with seven others in 2012/2013 and many more having no expected compliance date. CAL has also been surprised to discover a big difference among the 33 local authorities in London in terms of how much they know about indoor air quality standards in their buildings. Some have been able to provide quite detailed information on compliant buildings whilst others seem to have little idea of which buildings comply with EN 13779.  Many local authorities have told CAL they do not know about compliance with EN 13779 in some or all of their schools because they are independently managed.
