Product review (3 stars): Correct size and fit..... But
They are the correct size and fit nice and snug. But I did not like how the charcoal was loosely placed in the plastic housing. A lot of open/empty space, plus some of the charcoal grains fell out of the plastic housing. I would have expected a tighter packed charcoal system with fiber/cloth wrapping inside the housing. But they work and I will be using them for as long as I can.
