Are there three filters in a Ceradyn pack...

Are there three filters in a Ceradyn pack or just one? My TDK requires three filters.

There is just one filter in the pack (so replacing three of them would be pricey).


How is this different from the EXT0016?

How is this different from the EXT0016?

Essentially, they are both the same except for the inner core of their filter elements, the rest is EXACTLY the same. The Gravidyn elements have an inner core of activated charcoal inside the elements to removed bad tastes, residual chemicals in the water and odors, as opposed to the Ceradyn elements which has a rock media inner core.
