Understanding Hepa filters
An appropriately specified Hepa filter can be used in mechanically ventilated spaces and recirculating systems to practically remove small airborne particulates. CIBSE Journal technical editor Tim Dwyer looks at what must be considered when integrating them into HVAC systems
Clear guidance: TR40 Best practice for exhaust ventilation
The risk of death and illness because of exposure to hazardous substances in the workplace can be cut by following the best practice guidance in ILEVE and BESA’s new TR40 publication. Alex Smith summarises the guidance aimed at the safe design and installation of local exhaust ventilation
Calculating Covid-19 risk according to activity and indoor space
