Of every 100 hospitalized patients, 7 in developed and 10 in developing countries will acquire at least one healthcare-associated infection, according to WHO. Healthcare-associated infections (HAI) are a huge cost for health care systems worldwide. It is estimated that in Europe alone, 16 million extra days of hospital stays and 37 000 unnecessary deaths yearly are due to HAI. Yearly financial losses are estimated to be at least 7 billion euros in Europe alone.
Micro-organisms or dust particles carrying infectious agents can remain airborne for an indefinite time when they are small enough. Current fiber filter (HEPA) based systems are not sufficient to prevent airborne transmission. Specialized air decontamination procedures are required to control infections. Premium air quality prevents HAIs and is an investment that will pay itself back.
