In a recent article published by REHVA, the Federation of European Heating, Ventilation and Air Conditioning Associations, Peter Dyment, the Building IAQ and HVAC energy consultant for Camfil discusses Clean Indoor Air for health and sustainability.
REHVA, are dedicated to the improvement of health, comfort and energy efficiency in all buildings and communities.
Peter discusses how there is an overriding need for people to breathe clean healthy air in both residential and commercial buildings today. Many buildings may be located in polluted industrial city locations or maybe in relatively clean rural settings.
There is an increasing trend for many people to work from remote locations or from their place of residence.
Many designers and engineers advocate use of ventilation methods that utilise naturally occurring air currents in buildings. Broadly these design solutions can be grouped under the name of passive ventilation. The great attraction of these types of solution is that they have low levels of energy use but the main drawback is that they are usually unsuitable for use in locations with high levels of air pollution.
These are air filter units that combine High efficiency particulate air (HEPA) filtration to remove PM2.5 and NO2 as well other commonly experienced pollutants. These air purifiers or air cleaners if they remove just particles are used in residential situations or healthcare applications. Removing aspergillus spores to protect vulnerable children and pollen removal to prevent asthma attacks are two recent needs that have been met.
Using a standalone air purification unit that delivers clean air at point of need if often a quicker more effective IAQ solution than trying to get a large unmanageable centralised HVAC system to service a small area in a large building with air. It can also save energy if the main HVAC system can be stepped down.

Sustainable Development Manager at Camfil, Myriam Tryjefaczka, participated in the Indoor Air Quality “There is only one air: better indoor air for better health” session at Green Week, where she called upon the EU policymakers to step up and harmonise legislation on Indoor Air Quality across Europe.
This year’s Green Week, the biggest annual conference on European environmental policy, was dedicated to Air Quality, as 2013 has been designated European Year of Air. A comprehensive review of EU air policy is scheduled to take place in fall 2013.
In her presentation, Ms Tryjefaczka referred to the tangible benefits of tackling indoor air pollution in terms of health, productivity and energy efficiency given that the indoor environment, where Europeans spend 90% of their time, can be up to 50 times more polluted than outdoors. She also pointed out that ventilation systems, with adequate design and maintenance, can reduce people exposure to indoor air pollution.
Ms Tryjefaczka stressed that:
“2013 is the EU Year or Air and therefore an opportunity to create a better environment for EU citizens, not only outdoors, but also indoors”. Continue reading
Article by Peter Dyment, Energy Consultant, Camfil Farr
I am like almost any other person on this planet. My aim is to live as long as possible and keep myself in good health for as long as I can. So it came as a bit of a shock to discover that I could lose years off my life and many more years of healthy living and a good quality of life. How can this be? After all I live in modern industrial country with a high standard of living and medical care.
Modern living in cities and industrial areas turns out to be the source of the problem. Air pollution is not just on the outside, but also indoors where we work and at home. So what can I do to stop my health being damaged?
First of all I need to understand the problem. This is the gist of it. We all have to breathe air to live. The air we breathe is mainly indoor air because we spend up to 90% of our time inside buildings according to recent studies. The air inside buildings where we live and work should be clean and free from air pollution but often it turns out to carry a toxic mixture of traffic exhaust gases and fine dust particles coming in from the outside and from the inside bacteria with moulds, fungal spores and other small organic bodies and parasites.
