IQAir stand-alone air cleaner reduces risk of MRSA contamination
An IQAir Cleanroom H13™ air purifier can significantly reduce MRSA contamination in patient isolation rooms, according to a study conducted by the Department of Biology at Nottingham City Hospital (U.K.).
Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterial infection that is highly resistant to antibiotics and thus difficult to treat. Hospitals, nursing homes, gyms, and even pediatric nurseries are at elevated risk of the spread of MRSA infections. According to the Centers for Disease Control, MRSA in healthcare settings typically causes severe and life-threatening infections, including bloodstream infections, surgical site infections and even pneumonia. Outside of hospitals and other healthcare settings the condition often appears as a skin infection.
In the Nottingham City Hospital study, the researchers measured surface contamination in rooms without air filtration in comparison to rooms with the IQAir Cleanroom H13 operating at various airflow rates. A strong association was noted between air filtration rates and the mean number of MRSA "colony-forming units" on surfaces in the room. The study concluded: "Placing IQAir portable HEPA-filtration units within MRSA isolation rooms can significantly reduce the contamination of environmental surfaces with MRSA." The study was published in the Journal of Hospital Infection and is available online at www.sciencedirect.com.
Reduction of airborne contaminants
The reduction of airborne contaminants is a vital ingredient for environmental control in medical laboratories. While contaminants on surfaces can be reduced with surface cleaning and disinfection procedures, the air in a medical laboratory benefits from medical-grade air filtration of a wide variety of airborne pathogens and contaminants.
Important factors in air filtration for laboratories
Two key factors to consider in developing effective air cleaning for medical laboratories are the filtration efficiency for the relevant contaminants and the system airflow in relation to the room size. IQAir follows this two-step approach in selecting the right air cleaning system for a particular laboratory. First, IQAir determines whether the contaminants of concern are particulate, gaseous or both in nature. If gaseous pollutants need to be removed, IQAir selects the appropriate gas-phase removal media technology. Then IQAir determines how many times per hour the air cleaner is required to clean the air in the laboratory in order to produce the desired air quality improvement.
Medical laboratories in hospitals, clinics and other facilities choose IQAir for its advanced air cleaning expertise and superior filtration technologies. Throughout the world, IQAir is a leading supplier of compact air cleaning systems and HVAC system filter upgrades. IQAir’s Cleanroom™ Series of air purifiers were designed specifically for the needs of laboratories dealing with microorganisms, If gaseous pollutants are also of concern, the GCX Series offers targeted control for most laboratory applications.
Proven effective even for particles smaller than 0.3 microns
One important difference between IQAir and many other air cleaning systems is its proven filtration efficiency, both for particles as well as for gaseous pollutants. While standard HEPA filters are designed to stop particles only down to 0.3 microns in diameter, IQAir HyperHEPA® filtration is proven to filter particles down to 0.003 microns, the smallest particles that exist. That is critical when you consider that most viruses, for example, are smaller than 0.3 microns in diameter.
That’s just one of the reasons why the Hong Kong Hospital Authority chose IQAir to help combat the spread of the deadly SARS virus.. At a typical size of 0.08 microns, the SARS virus is well below the 0.3 micron and larger efficiency range at which other manufacturers test . But IQAir’s HyperHEPA filtration is highly effective against the tiny virus, filtering more than 99.5 percent of all particles down to 0.003 microns.
