Medical air purifiers use high-efficiency filters that include HEPA, ULPA, and ASHRAE filters for particulates, bacteria, and some viruses. Ultrafine particles, smaller than 0.3 microns, can accumulate deep in the lungs and cause increased health effects. Medical HEPA filters are thick, pleated mechanical air filters that capture 99.97% of unwanted air particles. The folds create a barrier of fibers that are randomly arranged and used to trap contaminants such as dust and dirt.
Particles are trapped in three ways: diffusion, interception or impact. When the particles, usually gaseous, are smaller than 0.1 microns in size, they collide with each other and delay passage through the filter. This is considered diffusion and is essential for an intercept or impact with gas particles to occur. Interception occurs when particles adhere to the fibers of the HEPA filter. Impaction occurs when larger particles become embedded in fibers.
A filter that captures only 50% of the particles could be certified as suitable for medical use. The decision depends on the FDA. Hospitals must use large air distribution systems that incorporate MERV 8 prefilters and MERV 14 final filters. Air purifiers are generally known to disinfect air by absorbing contaminants and allowing only clean, fresh air to circulate in a space. However, medical air purifiers to remove dust and other contaminants can remove 99.7% of airborne particulates, resulting in better air quality and numerous health benefits.
Medical air purifiers recycle harmful air to create clean air that helps reduce the risk of future health problems. Smart Air is a certified B company that is committed to combating the myths used by large companies to increase the price of clean air. A medical grade air purifier from Australia with advanced technology that maximizes air filtration in health facilities and also works as an air purifier for COVID 19 hospital use.
What Does This Mean For You?When you have a Sans air purifier in your indoor area, you can be sure that the air you breathe is safe, clean, and pure, especially when you consider that this filter works in conjunction with three other layers. The UV-C light neutralizes these pathogens so that (a) they don't come back out of the air purifier and (b) they can't grow on the filters. Most advanced filters have a replacement icon, and when the icon light comes on, it's an indication to check or replace the air filter.
HEPAor HEPA type filters are MERV 9-12 rated, which means that they can only filter airborne particles that are one to three microns in diameter.
The Euromate PAS 3300: An Australian Air Purifier For Medical UseThe Euromate PAS 3300 is an Australian air purifier for medical use that has a HEPA filter to remove pollutants from space.
A medical air purifier is specifically designed with HEPA filters to remove particulate matter from hospitals, clinics, daycare centers, and other health centers. Smart Air is a B-Corp-certified social enterprise that offers simple and practical air purifiers and provides free education to protect people from harm from air pollution.
