Air filtration is the process of removing impurities from the air. It can be used to improve air quality in homes or create clean rooms in hospitals and research facilities. The air passes through filters that trap different types of impurities, and the level of filtration determines the cost. Air filtration systems can also be used to recirculate air in aircraft or draw in outside air for filtering.
Air filtration is a process where air is passed through a filter system to remove impurities. There are many different types of air filtration, ranging from filters used to improve the air quality within a home for the benefit of allergy sufferers to filtration systems used in biological research facilities to prevent release into the air. environment of dangerous organisms. A number of companies specialize in installing air filtration systems and manufacturing devices that can be used for air filtration.
The air can contain a wide variety of impurities that can cause health or other problems while remaining invisible to the eye. Dust, particulate matter and pollen can trigger allergic reactions, for example, and the air can carry microbes that make people sick, along with gases and chemicals that can be linked to illness. Sometimes, the air just smells bad. Air filter systems are also used for tasks such as recirculating the air in an aircraft.
In an air filter system, the air has to pass through some sort of filter that traps the impurities in the air. The design of the filter determines which impurities will be trapped, from soot to viruses. The air can either be sent through a series of filters to progressively remove as much as possible, or passed through a single large filter designed to trap major impurities. The higher the level of filtration, the more expensive the system tends to be.
An example of an air filtration system is ductwork used in laboratory facilities. This system connects to fume hoods and isolation boxes where hazardous materials are handled, drawing the air from these workstations up to the filtration system and trapping the hazardous materials before releasing the air into the environment. This type of air filtration system is designed for the safety of the public and the environment. Another example are the filtration systems used to create clean rooms with the cleanest possible air in order to protect patients in hospitals or to create a controlled environment for research.
In homes and businesses, an air filtration system can be used to improve air quality and keep people more comfortable. In this case, the goal may be to eliminate odors and large particulate matter. The system can continuously recirculate air through the structure or draw in air from outside and filter it before bringing it inside. Such systems can also be connected to heating and cooling systems to filter the air that passes through these systems.
