There are a lot of \u2018false claims\u2019 being made to drive demand for indoor air quality solutions in the face of the Covid-19 crisis, warns Nathan Wood from the Building Engineering Services Association<\/a> (BESA)<\/h2>\n

According to the BESA there are a lot of false claims being made for different air quality technologies with the potential to help tackle the transmission of Covid-19<\/a>.<\/p>\n

Nathan Wood said there would be greater chance of success if more technology providers collaborated to produce full system solutions.<\/p>\n

\u201cWe really need to cut out the BS,\u201d said Wood, who is chair of BESA\u2019s health & wellbeing in buildings group.<\/p>\n

\u201cRebranding an old product and giving it a new filter is not innovation. There is a lot of responsibility on the HVAC sector<\/a> at the moment and we have to be careful about what claims are being made.\u201d<\/p>\n

Wood said that people were spending an average of 90% of their time indoors before the pandemic struck \u2013 and estimated that figure could well now be as high as 98% (mostly at home) placing even more pressure on the industry to deliver robust indoor air quality (IAQ) solutions.<\/p>\n

\u2018Misinformation doing the rounds\u2019<\/h3>\n

\u201cThere is more to this than simply getting the right amount of air into a room,\u201d Wood told a recent BESA Covid-19 update webinar.<\/p>\n

\u201cThe direction of the airflow is critical for IAQ.\u201d<\/p>\n

He added that employers needed to give more thought to employees\u2019 working conditions at home.<\/p>\n

\u201cIf you ask someone to work from home that doesn\u2019t mean you can then just forget about your responsibility for their health and wellbeing,\u201d he said.<\/p>\n

Peter Dyment of filter manufacturer Camfil<\/a> told the webinar that there was \u201clots of misinformation doing the rounds\u201d. This included a claim that HEPA filters were not capable of capturing Covid-19 particles, which he said was \u201ccategorically untrue\u201d.<\/p>\n

The virus particles measure between 0.12 and 0.16 microns, which is well within the HEPA range \u2013 and the droplets inside which they are transmitted are even larger. He also advised the industry to make sure it was only using filters that were tested to the relevant industry standards.<\/p>\n

Hillary Spicer of E-CO<\/a> added that ultra-violet technology could play an important part in neutralising virus particles in the airstream. He said it was routinely fitted to air conditioning and ventilation systems in the US, but most of Europe had been \u201cslow and backward\u201d in the adoption of this approach.<\/p>\n

\u201cThere is no silver bullet \u2013 in many cases you will need to combine technologies to get the right outcome,\u201d he told the BESA webinar.<\/p>\n
