Filter media made of micro-glass and cellulose are two of the most common types used in a variety of situations. They have different properties that make them suitable for different applications.
Micro glass media is composed of tiny and uniform inorganic glass fibers. This provides a high dirt-holding capacity and a very fine filtration rating for micro glass media. It is a good choice for applications where chemicals and solvents are present because of the resistance of micro glass media. However, the cost of micro-glass media is higher than that of cellulose and can result in a greater pressure drop.
Cellulose media is made from organic cellulose fibers that are larger and more irregular in size than glass fibers. This results in cellulose media having a lower dirt-holding capacity and a coarser filtration rating. Nonetheless, cellulose media is less costly than micro glass media and exhibits a lower pressure drop. Cellulose media is also more absorbent than micro glass media, making it a good choice for applications where fluids need to be absorbed.
Below is a table that summarizes the key differences between micro glass media and cellulose media:
The optimal filter media selection for a particular application will be contingent upon the specific requirements of that application. For example, if a high dirt holding capacity and a very fine filtration rating are required, then micro glass media would be a good option. Nevertheless, cellulose media would be a better choice if cost and pressure drop are important considerations.
Ultimately, the most effective approach to determining the ideal filter media for your endeavor is to consult a specialist in the field of filtration.
