Which industries Use Commercial Air Filters ?

Our filters serve numerous applications such as hospitals and health care facilities, bio-tech and electronics manufacturers, gas turbine power plants, clean room facilities, museums, schools and universities, commercial and government buildings, industrial manufacturers and many others. There aren’t many locations that wouldn’t benefit from the application of air filtration because clean air is clean living.

When deciding if it’s absolutely necessary however, there are a few questions you should ask yourself. Is your destination near any industrial polluting plants? Are the products or machinery in your building susceptible to damage from particulates? Is there any children or elderly in your building? Do your customers or tenants complain about a lack of air quality? These are all basic examples of industry traits that would make air filtration imperative.

Where filters are truly relied upon are places such as:

Hospitals: The highest priority for filtration in hospitals should be maintaining clean and healthy air for its patients and staff. Providing an environment using competent air filtration equips patients, staff and visitors with an added degree of protection from airborne microorganisms that can cause infection, disease and even death.

Education: A classroom environment requires quality air filtration. Protection against atmospheric particulate matter which consists of microscopically small solid/liquid particles suspended in the air that can penetrate the respiratory system and damage students lungs over time.

Hospitality industry: most air pollutants comes from foot traffic, open and closing doors, visitors carrying particulates from around the globe and the production of food. These impurities include bacteria, fungus, atmospheric dust etc.

What is a HEPA Filter?

High-efficiency particulate arrestance (HEPA) is a type of air filter. When a Filter meets HEPA grade requirements they have several possible applications including clean rooms, medical facilities, aircraft and homes. The filter must appease certain standards of productivity set by the United States Department of Energy. To qualify as HEPA by US government standards, an air filter must remove (from the air that passes through) 99.97% of particles that have a size of 0.3 µm.
HEPA filters are composed of a mat of randomly arranged fibers. The fibers are typically composed of fiberglass and possess diameters between 0.5 and 2.0 micrometers. Key factors affecting its functions are fiber diameter, filter thickness, and face velocity. These particles are trapped (they stick to a fiber) through a combination of the following three mechanisms:

Interception: Where particles following a line of flow in the air stream come within one radius of a fiber and adhere to it.

Impaction: Where larger particles are unable to avoid fibers by following the curving contours of the air stream and are forced to embed in one of them directly; this effect increases with diminishing fiber separation and higher air flow velocity.

Diffusion: An enhancing mechanism that is a result of the collision with gas molecules by the smallest particles, especially those below 0.1 µm in diameter, which are thereby impeded and delayed in their path through the filter; this behavior is similar to Brownian motion and raises the probability that a particle will be stopped by either of the two mechanisms above; this mechanism becomes dominant at lower air flow velocities.
