Nearly a quarter of a century after deeming diesel exhaust “probably” carcinogenic, the International Agency for Research on Cancer (IARC) has concluded that sufficient evidence now exists that it does indeed cause cancer in humans. The announcement — made by the IARC on June 13 — puts a spotlight on technologies and products that can safely remove dangerous diesel exhaust particles from the air. Chief among them: cutting-edge air filters that can keep indoor environments — where people spend up to 90 percent of their time — safe.

The IARC, part of the World Health Organization (WHO), based its conclusion on a review of a large study performed by the National Cancer Institute and the National Institute for Occupational Safety and Health, two U.S. government agencies deeply involved in the fight against cancer. The announcement is significant, as position statements from the WHO and other influential health organisations often lead to new government policy and legislation, having a great impact on the lives of people around the world.

While much research still needs to be performed on the relationship between diesel exhaust and cancer, one thing is certain: proper air filtration, effective at keeping diesel exhaust particles out of the indoor air, is essential.

In recent years, great progress has been made in dramatically improving the efficiency and effectiveness of both residential and commercial air filters. While many businesses, homes, hospitals, manufacturers, and office buildings still use traditionally designed air filters — which can quickly degrade in use — those that have switched to more innovative designs have been able to see not only better air filtration, but at reduced energy, maintenance and replacement costs.

Indeed, air filters from Camfil Farr — the world’s leading provider of clean air solutions — have been shown to effectively and consistently remove and trap particles associated with diesel exhaust from the air, reducing human exposure. In side-by-side testing, the Camfil Farr filters, which use an innovative fine fibre media, have demonstrated that they can do a better job than traditionally designed filters in removing the particles — and do so for a longer period of time, with less energy needed to push the flow of air through the filter. This efficiency is maintained even when exposed to diesel. The result: people are protected — and that protection continues even as the air filters continue to operate over time.

Diesel exhaust may be dangerous, but with the right air filters, the risks can be reduced — and people kept safe.  When was the last time you checked the effectiveness of the air filters in your buildings?
