HEPA Filter Replacement
The Risk of Infection
When heating, ventilation, and air conditioning (HVAC) systems are equipped with high efficiency particulate air (HEPA) filters, they can easily over time collect and trap hair, skin cells, debris and dust therefore, acting as a reservoir and food source for a wide a variety of microbes such as methicillin-resistant Staphylococcus aureus (MRSA), Pseudomonas aeruginosa, and aspergillus mould. The contaminated air then can circulate throughout the hospital premises, possessing a high risk to staff, visitors and patients, especially the most vulnerable such as the elderly and immunosuppressed patients. In order to improve air quality and minimise transmission of harmful microbes, HEPA filters that have been installed for more than 6 months must be replaced. As part of an infection prevention and control strategy, it is essential to ensure HEPA filters remain performance-efficient and able to keep consistency of pressure within hospital rooms as well as maintaining high level of filtration.
Did you know?
More than one third of all nosocomial infections possibly involve airborne transmission1
Contaminated air with microbes and particulates can cause respiratory tract complications such as pneumonia2
The risk of a leaking HEPA filter has already been reported showing a correlation between increased microbiological counts and leaking HEPA filters3
Poorly maintained ventilation systems may eventually act as a source of, rather than as a defence against, aerosol/airborne infection4
How Inivos Can Help
Our HEPA filter replacement service can be delivered as both an on-call service for emergency situations, a specific area or project, or as a scheduled managed service contract. Our work is carried out in compliance with all relevant health and safety regulations5. This enables us to reduce the risk of a patient acquiring an infection whilst in hospital, by reducing the number of reservoirs available for dangerous pathogens to multiply in.
Our highly-trained mobile technicians provide the full service including replacing of HEPA filters and providing a certificate of the filter specification and date of replacement and can be used in conjunction with our other services including filter integrity testing and AHU cleaning. Through our managed 24-hour on-call helpline a fast turnaround on all services can be achieved minimising clinical downtime.
Pre-Replacement Risk Assessment
We perform all the required risk assessments such as isolation of filter and condition assessment to ensure we deliver our service safely.
Our qualified technician will effectively and safely remove your worn, dirty and over-used filters and will replace them with new filters that have been tested to the new ISO 16890 standard.
After replacing HEPA filters, we assess the newly installed filters and provide certification for the changed filter. We can also provide a maintenance contract for replacement of your HEPA filters to give you assurance of the efficacy of your filters.
