FAQ

WHAT IS THE DIFFERENCE BETWEEN FILTER CARTRIDGES AND CARBON CARTRIDGES?

PURPOSE OF FILTER CARTRIDGES
Filter cartridges, such as Flo King Poly-Spun Disposables and Magnum Reusables, primarily remove dirt, particulates and other solids visible to the naked eye. These cartridges will not remove dissolved metals or organic impurities unseen by the naked eye.

See this link for Poly-Spun filter cartridge details.

And this link for reusable filter cartridge information.

Micron Rating: Filter cartridges are supplied according to micron rating. Lower micron ratings are designed to capture smaller particles, but also reduce the flow rate of the pump because the filter fibers are more dense.

PURPOSE OF CARBON CARTRIDGES
Carbon Cartridges remove organic contaminants. Sources of organic contamination include brightener breakdown products in plating solutions, drag-in of organic contaminants (such as surfactants from cleaner tanks or small amounts of oil), and deterioration of maskants and photoresists. Many of these organic impurities cannot be seen by the human eye. Some can make the solution cloudy. See this link for carbon cartridge details.

No Micron Rating: Carbon cartridges are not rated according to micron. The carbon itself has the capability to remove sub-micron organic particles (not visible to the naked eye).

There is, however, a 5-micron reusable filter blanket that surrounds the carbon inside the Flo King carbon cartridge.
