Final answer:
The removal of 99.9% of airborne particulate matter larger than 0.3 micrometers can be accomplished with a HEPA filter, which is capable of capturing a wide range of particles including dust, dirt, and biological contaminants. HEPA filters are used in both medical settings and homes to provide cleaner air.
Step-by-step explanation:
The removal of 99.9% of airborne particulate matter larger than 0.3 micrometers in size can be accomplished with a HEPA filter. HEPA stands for high-efficiency particulate air filter, which is designed with an effective pore size that can capture a wide array of particles including dust, dirt, viral particles, and bacteria as air passes through, thereby removing them from the air one breathes. These filters are commonly used in various settings, including medical facilities and homes, to ensure a cleaner air environment.
In clinical or laboratory settings, HEPA filtration is commonly used in clean rooms, isolation rooms, and to protect equipment such as biological safety cabinets from contamination. Other settings where HEPA filters are valuable include homes and offices to reduce the presence of allergens, irritants, and pollutants in the breathing air.
Moreover, electrostatic precipitators are another type of air cleaning device that uses electrical charges to remove particles from the air, though they are more commonly used industrially.
