Managing the high levels of dust and particulate matter during construction and renovation works can be challenging. Airborne particles can contaminate adjoining areas but can also cause health issues by triggering respiratory problems, asthma and allergy symptoms. Professional construction air purifiers can be an effective way to control airborne contamination on and near construction sites.
Several widely used building materials emit particles in their dust when cut which is harmful when inhaled. These operations cannot be avoided during construction or renovation works, but they can be filtered to avoid potential harm to workers and building users:
Construction workers have a high risk of developing respiratory diseases because many common construction tasks can create high dust levels. Over 500 construction workers are believed to die from exposure to silica dust every year. It only takes a very small amount of the very fine respirable silica dust to create a health hazard. Recognizing that very small, respirable silica particles are hazardous, HSE guidelines require construction employers to keep worker exposures at or below an Exposure Level of 0.1 mg/m3.
Construction and renovation works in healthcare environments require particularly careful management, as the Aspergillus mould spores present in all buildings can cause serious problems for those with weakened immune systems.
Where construction is adjacent to, or near to, oncology or transplant units, even more, care is needed. Despite negative pressure and sealing the work area, a backstop is often required, with mobile high-performance construction air cleaners adopted within each treatment area. These units maintain clean air with sufficient air changes, ensuring any bacteria, viruses or particulates are effectively filtered.

Airborne contamination by ultra-fine particulates can be challenging to control, particularly in an environment where high dust quantities are present.
Large dust falling onto surfaces rapidly means more cleaning is required, but it is the small, airborne particles which can be inhaled and cause problems for construction workers. The common respirator masks used simply are not efficient enough to capture these small particles which pass directly through the mask.
Legal limits on air pollution guidelines involve particulate – dust and airborne particles, gases and chemicals, all of which can be present in a wide range of construction and renovation activities. The combination of particulate, chemicals and gases from a range of paints, varnishes and building materials can pose a significant problem for building operators. The use of standalone mobile construction air cleaning units with a combination of filtration media can address all of these categories simply and effectively.
