variety of monitors available – wall or desk mounted – which monitor and record all the vital elements of IAQ, including VOC, CO2, relative humidity and temperature. Where improvement is required, and where adequate systems are not already built into the fabric/ design of the building, or are out-dated, there are some straightforward and cost- effective retro-fit solutions:
Humidity control is achievable as stand-alone units or positioned above a false ceiling to regulate levels. Scientific evidence has proven that maintaining relative humidity between 40% and 60%
will significantly reduce the transmission of airborne viruses, she continues.
Stand-alone room filtration units can also provide fresh, clean air by trapping 99.99% of ultra-fine particles using HEPA filtration. This removes particles up to 0,003 microns, captures chemical pollutants (VOCs) using activated carbon filters, and can be completed with an app to allow condition monitoring and remote control.
She further explains that heat recovery units allow fresh air into a building whilst being filtered and recovering the heat from the extracted, stale air and can be extremely efficient.
“Provision for air movement, filtration and humidity all greatly improve Indoor air quality. Monitoring and recording
of these values is critical to establishing, and maintaining, a healthy air quality.
“As each building varies in its requirements due to location, usage, existing infrastructure etc, we do recommend consulting
a specialist who can advise
on the right solutions for your specific environment,” Ms Stone concludes.
