Clean air is a human right

Take a breath

Breathing air is essential for life. It is the very first thing we do when we are born. This is an instinct and naturally we expect the air to be clean but we do not instinctively question the quality of the air that we breathe.
However, in recent years the scientific community and global media are increasingly reporting on the links between human health and poor air quality.
Many national bodies and world organizations are addressing this problem. As the health and economic impacts become more apparent they endeavor to set new standards and raise awareness.
It is our responsibility to support these global initiatives that will allow you to Take a Breath with total confidence. Our mission with the Take a Breath campaign is to create interest, provide information and raise awareness about indoor and outdoor air pollution.

So Take a Breath and dive with us under the surface of “Air Quality”.

Interesting questions answered in an in depth yet understandable way.

PM1 Tracker

Make the Invisible visible


For over 50 years Camfil has lead the way, striving to tackle air pollution and improve Indoor Air Quality in the quest to make clean air a human right.

Unlike dirty water, air pollution is not visible and therefore we are often unaware of how good or bad our indoor air quality is.

With the new innovative PM1 Tracker, Camfil is making the invisible, visible. Now, through this handheld device, you will be able to see your Indoor Air Quality within minutes.


Sit back, take a breath and join our ISO16890 educational webinar


ISO16890, a new global standard for testing and classification of air filters was recently approved for imminent release.  This landmark development will provide significant benefits for designers, specifiers, purchasers and users of air filters in ventilation systems.

  • PM1toPM10

    Let’s compare PM1 to PM2,5 and PM10

    PM1 means all particulate matter with size smaller than 1 micron (a thousandth of a millimetre). The body has some natural defences against PM10 and PM2.5, such as nasal hairs and mucous membranes but not against PM1. These smaller PM1 particles can contribute to respiratory problems and other serious diseases.
  • dance

    Transparency, equality and opportunities

    The standard will provide a level playing field for filter manufacturers. It will be easier to compare competing products. This will, at one end of the scale drive product innovation and customer value and at the other end of the scale serve to eliminate some of the very poor performance products from the market place.

    Schoolchildren benefit from better air

    Schoolchildren can benefit from better indoor air quality and have improved  “reading test” results by 13%.
  • sickleave_infographics

    Improved air quality reduces sick leave

    Improving indoor air quality reduced sick leave rate by 39% and costs by 44%, according to a study in Australia.
  • ultrafine

    Ultrafine metallic particles have been found in the human brain

    06 September 2016, Researchers at Lancaster, Oxford and Manchester universities report a possible link between ultrafine (<0.1μm) metallic particles that have been found in the human brain to onset of Alzheimer’s disease. The metallic particles appear to have been exposed to high temperature (fused) and the suspected source of the particles is diesel engine emissions.
  • 4th_infographics

    Air pollution, the 4th highest threat to human health

    Air pollution is the fourth highest risk factor for premature death worldwide and by far the leading environmental risk factor.
  • PM1isSmaller

    PM1 is smaller than 1,000th of a millimeter

    Particulate matter (PM) pollution is often reported in terms of PM10 (all particles with effective size < 10μm) and PM2.5 (all particles with effective size < 2.5 μm). However, the scientific and medical communities are increasingly reporting that the most harmful particles to human health are the smaller PM1 fraction (< 1μm). To be even more precise, it is the so called ultrafine (<0.1μm) and nano particles (< 0.05 μm) that have the greatest negative impact on human health.
  • weight_infographics

    We breathe more than 15 kg air/day

    Humans eat 1kg of food each day, drink 2,5 kg of fluids and breathe more than 15kg of air per day. We take care about the food we eat and the water that we drink but rarely do we consider the air we breath
  • building_infographics

    The indoor environment can be up to 50 times more polluted

    Airborne particles enter our buildings through ventilation systems and open doors and windows. In fact, the action of the ventilation system combined with indoor sources of pollution can mean that in many cases indoor air is up to 50 times more polluted than outdoors.
  • Globe

    ISO16890 – the standard for air filters

    It is highly significant that this standard has global applicability. As if to reinforce that point the approval decision was 100% positive from all voting countries. Until now, there was no such standard. In the Americas, ASHRAE standard 52.2 dominated, in Europe EN779 was dominant and in Asia and the Middle East both standards were used side by side. The standard will eliminate confusion and prevent invalid attempts to cross-reference results from the different existing test methods.
  • face_infographics

    More than 25 million particles with each breath

    In highly polluted areas we breathe more than 25 million particles with each breath
  • hands

    Encourage global trade

    Global applicability will remove a barrier to international trade. After all, it is not unusual in the case of a major construction project that the design engineers, the constructors and the project location are all in different countries.
  • dartboard

    Eliminating confusion

    The new standard delivers benefits for specifiers and users of filters as well as for the air filter industry. The standard is more intuitive, the filter testing procedure and the classification system are better aligned with real world air pollution.
  • indoors_infographics

    We spend up to 90% of our life indoors

    We spend up to 90% of our life indoors. This means that indoor air pollution can substantially influence our health.
  • mutagenic

    PM1 shown to carry mutagenic chemicals into buildings

    Polycyclic aromatic hydrocarbons are a group of more than 100 different chemicals that are released from burning coal, oil, gasoline, trash, tobacco, wood or other organic substances. Widespread in urban environments, PAHs are well known for their mutagenicity – their capacity to cause mutations and damage DNA – and their carcinogenicity – their ability to cause cancer. PAHs can exist as free particles, or in the molecular form. However, many are present condensed onto the surface of PM1 particles. Exhaust emissions from cars and trucks are one of the major outdoor sources and PAHs can infiltrate the indoor air environment through ventilation systems to mix with other PAHs from indoor activities like cooking, heating, smoking and candle burning.

    Up to 5.5 million lives could be saved – every year

    There are 5.5 million premature deaths – around the world each year due to air pollution
  • exhausts

    Exhausts contain billions of very fine harmful particles

    Emissions from diesel exhausts have changed, some years ago diesel exhaust was characterised by black sooty smoke. Today, major advances in engine technology mean that emissions from diesel engines appear to be considerably cleaner than they used to be, to the point of being virtually undetectable. In reality however, the “clean air” contains billions of harmful ultrafine and nano-particles, all of which are totally invisible.
  • Aminimumof50

    A minimum of 50% ePMl filter efficiency

    One of the mast significant advantages is that the new procedure requires that filter efficiency be measured against the fine particle fraction PMl. This is important, because the medical and scientific communities are increasingly reporting that it is the PMl fraction that is mast hazardous to human health. Camfil strongly recommend the use of ePMl rated filters to reduce indoor air pollution and improve human health. According to the test protocol, filter efficiency must be measured both when the filter is unused and again when any electrostatic charge, which could artificially enhance performance has been removed from the filter. Both these results must exceed 50% efficiency for the filter to be rated as an ePMl device.
