Commercial Duct Cleaning

The air we breathe is a common vector for the transmission of harmful pathogens and poses a risk of causing an infection. Left uncleaned, air conditioning ducts provide a reservoir for airborne organisms to amass and multiply. The contaminated air then poses a greater risk when circulated through the building, especially in areas where immunocompromised patients are likely to be more susceptible to acquiring infection.

Risk of Infection

Hospitals are familiar with the risks of HAIs and the costs of MRSA infections. Evidence suggests MRSA bacteria and Aspergillus spores can particularly pose a risk as airborne pathogens through colonisation of ductwork. MRSA bacteria is commonly found in ‘dusty’ and inaccessible areas such as air conditioning or extraction ducts, and it has been evidenced that it can survive on surfaces or skin cells for up to 80 days, as well as being able to potentially travel the length of a ward through the air. Pseudomonas aeruginosa bio-aerosols have also been implicated as a cause of outbreaks from contaminated air-conditioning units.

With government including Mandatory HAI Surveillance on both MRSA and Pseudomonas infections, it’s vital that hospitals have a robust cleaning schedule for their air conditioning ducts and extraction systems to reduce the risk of outbreaks of HAIs.


The Most Susceptible

Whether it be in theatres or specialist areas which care for patients whose immune systems are compromised, maintaining air quality is essential in reducing the risk of transmission of infection. When these groups of patients acquire an infection, it is likely to result in a longer hospital stay, impacting the throughput of patients and bed capacity, as well as the cost of care.

In theatres, it is essential to provide safe, clean air to reduce the risk of Surgical Site Infections (SSIs). A robust schedule of duct cleaning is therefore especially beneficial to staff and patients in theatres, wards and treatment rooms, as well as specialist areas including ICU, oncology and respiratory clinics.

Did you know?

1.7m nosocomial infections occur each year, with nearly 100,000 associated deaths1

Airborne transmission is more prevalent in healthcare settings due to overburdened hospitals and the presence of immunocompromised patients²

MRSA disseminates widely throughout the ward and is commonly found in dusty, inaccessible high surfaces²

MRSA can survive on surfaces or skin scales for up to 80 days and spores of Clostridium difficile may last even longer²

Poorly maintained ventilation systems may eventually act as a source of, rather than as a defence against, aerosol/airborne infection²

How Inivos Can Help

Our duct cleaning can be delivered as both an on-call service for emergency situations, a specific area or a project, or as a scheduled managed service contract. Our work is carried out in compliance with all relevant health and safety regulations.

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 Service

We manage the project from end-to-end to ensure all stakeholders are aligned through clear communication of a complete project plan. Our teams of qualified technicians are able to operate 24 hours a day, 365 days a year to ensure rapid turnaround and minimum disturbance or disruption to the clinical schedule. This involves:

Pre-Cleaning Assessment

Our first step is to survey the ductwork and to take samples to actively assess the current the condition and implement the correct cleaning plan. This allows us to analyse the microbial growth and degree of dust contamination.

Active Cleaning

We then use the correct method to clean the ducts which may include using a rotary brush, in conjunction with an air mover, hand cleaning, air whipping or a process known as ‘wanding’.

Validated Assurance

After cleaning and disinfecting, we validate the efficacy with testing of the dust contamination and microbial growth, before providing you with a report. We also take photographs before, during and after our work to show you the results, in line with our evidence-based approach.
