Although all air scrubbers perform the same task, they do not all work in the same way. Traditionally, carbon or charcoal based filters absorb pollutants as they move through the filter. This type of carbon filter system can be effective but there are drawbacks. For example, because the filter merely traps pollutants it becomes a hazard by the time its lifespan has passed. Disposing of the these contaminated filters can be a problem. Purafil air scrubbers use an innovative media in their filter developed by Purafil that eliminates these types of problems.

Purafil air filtration media does not absorb pollutants. Instead, the granules in a Purafil air filter are designed to react to specific gaseous pollutants and use a process known as chemisorption, or gas-phase filtration, to convert the contaminants into harmless compounds. When a Purafil filter needs to be replaced, it is not a trap filled with dangerous chemicals but a harmless piece of refuse that can be safely handled and thrown away without special precautions. This alone makes the Purafil air filtration media superior to carbon and charcoal systems.

Chemical filtration has even more advantages. Purafil has created a wide range of media granules each of which reacts to a specific pollutant. After a needs analysis, custom media mixes can be created to deal with a facility's unique environment, and may be used to control corrison. Equipment can also be made to order to maximize efficiency. The Purafil media is also well suited for wastewater odor control and other specialized tasks.

Purafil air cleaning systems, and our industrial air filters can be found in office buildings, foundries, power plants and many other facilities in a wide variety of industries. The efficiency and safety of the chemical filtration system used by Purafil is ideal for extreme circumstances and you will find Purafil products in cleanrooms, hospitals and even museums.
