Are you looking for an air filter that can effectively remove contaminants from the air stream? If so, you may want to consider a 16x20x4 air filter with a MERV 11 rating. This type of filter is designed to provide between 80 and 85% efficiency in filtering particles between 3 and 10 microns in size, such as mold spores, anti-dust agents, and cement dust. It also offers between 50 and 65% efficiency in filtering particles between 1 and 3 microns in size, such as Legionella, lead dust, humidifier dust, carbon dust, and nebulizer droplets. Pleated air filters are more effective than non-pleated media at capturing airborne contaminants.
This is because they provide more surface area for trapping contaminants. As such, they are commonly used in food and beverage air conditioning systems, healthcare facilities, hospitality establishments, educational institutions, and industrial settings. A filter's MERV rating measures the efficiency with which it removes contaminants from the air stream based on the size of the particles it can effectively capture. It is important to note that 16x20x4 air filters with a MERV 11 rating offer less than 20% efficiency in filtering particles between 0.30 and 1 micron in size.
These include bacteria, most smoke, cores from sneezes, insecticide powder, toner for photocopiers, and face powder.
