What is a HEPA air scrubber used for? Remediation Mould spores are disturbed and become airborne during remediation. They must be filtered out of the air or they can settle and create a larger mould problem. Hospital Remediation Cleaning Construction dust can contaminate high-risk areas. Cleanroom standards suggest that a HEPA rated air scrubber can be used during the cleaning process to filter any contaminants which are made airborne while cleaning surfaces. Fire and Smoke Damage Cleaning A carbon filter can be placed inside an air scrubber which is used to filter out any smoke odours at the property. Industrial construction sites with concrete dust It is important to be breathing healthy air when cleaning a property post-construction. Using a HEPA rated air scrubber will provide some protection for the health of on-site occupants/staff. What is HEPA? In all of the above applications, it is necessary to “scrub” the air to remove particles that may be hazardous to your health. It may also be necessary for some construction or mould remediation sites, to reduce the contamination in the air to help prevent cross-contamination. Air scrubbers can also be used as negative air machines. Air can be exhausted out of a room and vented outside. This reduces the risk of the contamination in the affected area from escaping and causing cross-contamination to other rooms within the premises.
