Product review (3 stars): Works as intended
The basic design has been modified from a pleated paper 'filter' to some sort of a honey comb design. I was able to get a full season out of the previous design by rinsing them out every few weeks. Don'the know about the longevity of this design but they work fine.
Lowes has another brand on their shelf for $10 made the same way that are interchangeable.
