Phresh Professional Carbon Filters

Phresh Filters are state of the art carbon filters that scour the air to make it clean of dust, foreign particulates, organic compounds and odours. Phresh Filters are made with the highest quality RC-48 Australian activated carbon. Australian Carbon contains unique properties that are ideal for filtering smells and foreign particles. 
Phresh Carbon Filters are professional grade, designed to meet the demands of serious hobbyists and commercial applications.

There is no specific limit to the life expectancy of RC-48 carbon and your Phresh Filter. The total life span depends on the amount of impurities absorbed by the carbon over time. The rate of air movement through the carbon bed, total air impurities and climatic conditions are the factors that determine the speed at which the porous carbon granules reach maximum capacity. 

We suggest that a Phresh Filter will last the typical user two years, based on the following:

Phresh uses only RC-48 carbon. There is a global industry standard where carbon is tested for "ID factor" and are given an "iodine number" to American ATSM standards. ID factor can simply be explained as the measurement of the amount of iodine in milligrams that can be absorbed by a single gram of activated carbon. The higher the ID factor, the higher the absorption rate. The average coal based carbon is around 500 mg/g ID. On the other hand, RC-48 carbon has a guaranteed analysis of 1050 mg/g ID.
