What type of filter is commonly used in hospitals for air purification?

In hospital environments, air quality is of utmost importance to prevent infections and ensure patient safety. HEPA filters are widely recognized for their effectiveness in capturing very small particles, including bacteria, viruses, pet dander, dust mites, and pollen. The acronym HEPA stands for High-Efficiency Particulate Air, and these filters are capable of trapping at least 99.97% of particles that are 0.3 microns in size. This makes them particularly effective in healthcare settings where the air must be as clean as possible to reduce the risk of airborne contaminants and infections.

The use of HEPA filters in hospitals is often mandated by health regulations, as they provide a strong barrier against pathogens. Their efficiency in filtering out microscopic particles significantly contributes to infection control and enhances the overall atmosphere in medical facilities. Other types of filters, while beneficial in certain contexts, do not achieve the same level of filtration efficacy required in sensitive environments like hospitals.
