As you probably already know, if you have done research on bead filters, the beads float. The more buoyancy that the beads have, the better off we are. To increase buoyancy we have added air to each individual bead during manufacture. Why is this important? Because we want the beads to stay as close as possible to the top of the filter during backwash. We want the beads to stay afloat so they stay away from the outlet slots on the bottom laterals so as not to choke off the laterals preventing the debris from leaving the filter.
