In a comprehensive research study published in the February 2010 issue of the American Journal of Infection Control, it was shown that IQAir systems reduced airborne infection rates of invasive aspergillosis by over 50%, which is a highly statistically significant result. The research also concludes that the cost of procuring IQAir systems will be offset many times by the decreases in patient infections.
The study entitled “The impact of portable high-efficiency particulate air filters on the incidence of invasive aspergillosis in a large acute tertiary-care hospital” was conducted by a team of doctors and scientists led by Dr Zakir-Hussain Abdul Salam from the Epidemiology Unit and Infection Control Unit at Singapore General Hospital, the largest acute tertiary-care teaching hospital in Singapore. The data was collected over a 2.5 year period. In total, 48 IQAir units featuring HyperHEPA filter technology were installed in selected wards, including renal medicine, hematology, cardiothoracic surgery, nephrology, medical oncology and otolaryngology.
Not only does this study show that IQAir HyperHEPA systems are a very effective and powerful tool for hospital infection control, but also that the investment in IQAir will enable hospitals to realise substantial cost savings by reducing infection rates. To quote directly from the study text:
“Compared with patients without IA [invasive apergillosis], patients with IA have an average excess duration of hospitalization of 12.3 days and an excess cost of $ 51’779. Thus, the deployment of [IQAir] portable HEPA units is a very cost-effective strategy.”
In view of the fact that invasive aspergillosis is often fatal, with mortality rates ranging from 30% to 95%, costing vast amounts to treat, IQAir systems can help save lives as well as costs, thus making it the intelligent and validated choice for airborne infection control in hospitals.

For over 40 years, IQAir has been at the cutting edge of indoor air purification. Started by two German brothers in the the early 60s, IQ Air is today an international, Swiss-based industry leader in the field of high-efficiency air purification. When clean, healthy indoor air is of the essence, IQAir is able to provide air cleaning solutions which are highly effective and yet affordable. IQAir’s innovative strength stems from its own R&D and manufacturing. This rare approach, by today’s standards, has led to products which set new standards in performance, style and quality.
