Mechanical and electronic air filters – the backbone of defense against airborne sickness

When you work in healthcare, you get used to extra precautions as part of the job. Wearing personal protective equipment, or PPE, goes beyond gloves – sometimes, it requires a full isolation suit, complete with a hood, facemask and banded sleeves to render yourself airtight. All this effort could be to simply stock a supply room in the O.R., but you can’t take any chances and risk spreading germs! While the hospital is always loaded with the ill and injured, the heating and air conditioning system is one of the hospital’s best defenses against the spread of airborne illnesses. As far as filtration goes, the hospital’s HVAC system is equipped with standard air filters, mechanical air filters, and even electronic air filters – all working side by side to ensure the cleanest possible air is available to visitors and patients. While the standard air filters work to trap dust and dirt in the office environments of the hospital, the mechanical air filters are put to use in the sterile environments as a means to trap even the smallest dirt and dust particles. However, that isn’t guaranteed to be enough either, which is why the electronic air filters are put to use as well! These electronic filters ionize particles as they pass through the filter, which causes them to stick to a charged plate in the filter as well. This kind of filter is most expensive due to upfront and utility costs, but it’s the absolute best defense against any possible contaminants in the air. Like I said, the healthcare industry is built on the ability to treat injuries, reduce recovery time and discharge patients at their proper health. It’s hard to accomplish such a task if the hospital is circulating air filled with irritants and bacteria!
