HEPA filtration technology doesn’t get the attention that it deserves. And when it does get consideration, that focus is generally on asthma, allergies and other conditions affected by poor indoor air quality. But hospitals all around the globe are using HEPA. So there must be more to it. And there is; for example, a recent study published in one of the world's leading medical journals showed how HEPA filtration thwarts the spread of invasive aspergillosis (IA). Aspergillosis is a ubiquitous mold, but most species of aspergillosis are not harmful to humans. However, there are some species, such as Aspergillus fumigatus and Aspergillus Niger, which can cause a broad spectrum of fatal diseases in people.
When these diseases occur, the mortality rate is extremely high. And if the aspergillosis mold is present, it spreads through the air we breathe infecting the susceptible quickly, efficiently and lethally. You may have never heard of IA, and thus might think that such an event is rare, and indeed, they are, usually.
But many hospitals deal with situations that are highly susceptible to aspergillosis infections: organ transplants, blood diseases and immunosuppressive therapy. Hospitals also often host environments that promote formation of the mold: maintenance, renovation and construction. So combined, this can be a lethal combination, and hospitals must take preventative steps from allowing those IA infections to occur at all.
In hospitals where an aspergillosis outbreak has occurred, the mortality rate in affected patients has generally been 95-percent or higher. That is an astonishing figure. A modern hospital should simply not have a mortality rate that high ever for any reason. Yet according to the study performed by Dr. Zakir-Hussain Abdul Salam, hospitals were able to use portable IQAir HEPA air purifiers to reduce IA infections by as much as 50-percent. And in hospitals that took preventive measures, they were able to prevent the IA infections from ever occurring.
So why is this research important? Well, IA infections are becoming increasingly more prevalent, which is something that the study focused on. The mold itself is no more prevalent than it has ever been. But what is happening is that we now have more advanced medical procedures, the byproduct of which is susceptibility to IA, and therefore more patients at risk. As these numbers rise, it is becoming increasingly important for hospitals to stem the tide, which is why so many are turning to HEPA products.
So how does HEPA air filtration work? Well, far simpler than you might expect based on the dangerous nature of IA. HEPA air filters comprise of dense glass fibers that trap the pollutants and contaminants as air passes through them. The trapping occurs several ways, and once trapped, the particles remain that way, which is why we must change the air filters regularly.
Comprehensive air filtration systems also use other filter mediums in addition to HEPA, but HEPA is the most important component. If HEPA technology is the choice of hospitals to prevent deadly infections, then it is little wonder why so many people are turning to it to protect their families. A HEPA air purifier will be one of the best investments you ever make: Your children will breathe easier, sleep better and be less susceptible to asthma and other allergy conditions.
