Yet studies have shown that the air quality inside many hospitals is poor. Studies also show that cleaner indoor air aids patient recovery and decreases physiological stress. As a result, hospital administrators might need to implement an air filtration strategy to combat the problem.

Hospitals, as well as nursing homes, dental offices and fertility clinics, must be a bastion of cleanliness and health. Critical equipment must also be protected from harmful substances that can interfere with their operation. Energy savings and flexible air filtration systems for operating theatres are also a high priority these days.

These goals are only achievable with a filtration system that is effective at removing even the smallest pollutants from the air. Air filtration from Camfil can hold the key to meeting these critical challenges.

Many hospitals also provide specialisation in order to offer better patient care. This applies for infectious disease units, oncology units or haematology units. In these units, highly skilled staff must deal with highly sensitive patients who require either extreme patient protection or specific nurse and doctor protection.

To address the issue and find the right air filtration solutions, it’s important to understand the major causes of poor air quality inside healthcare facilities.

Sick patients at healthcare facilities can unfortunately contribute to air quality that is less than ideal. Coughs can contaminate the air and surfaces within a hospital room or lab. Open wounds or infections can transfer viruses and bacteria from patients’ bodies onto surfaces such as bedpans, mugs, plates, silverware, bedding and other materials. Once these materials are disturbed, those contaminants become airborne.

Many public hospitals in large urban areas were constructed many years ago, when innovations in ducts and vents were not as highly advanced as they are today. As a result, the air drawn into the hospital may not be properly filtered through the outdated ductwork. So, common pollutants such as dust mites, dirt, pollen and airborne bacteria can more readily circulate through the vents.



Moisture presents a particular problem in ductwork. It often leads to problems such as mould and spores, not to mention the risk of salmonella and nosocomial infections, which can grow into a major health issue beyond compromised air quality alone.

Much of the air that circulates through a hospital is drawn in from the outside. The indoor air quality in many health facilities therefore largely depends on the outside air quality. Dangerous vehicle exhaust fumes and odours can pose a threat by entering the building via the HVAC system.

For more than 50 years, Camfil has been an industry leader in the design and manufacturing of air filtration systems that are innovative, functional and health affirming. Camfil places a high value on the efficiency of its products, and through rigid testing, has developed solutions to the most complex clean-air problems facing the world.
