Product review (4 stars): No issues so far
This replacement filter, structurally, appears to be equal to the OEM filter which came with the unit. It has a dust filter wrapped around the main "wick" , but it is not blue. I would have given this filter 5 stars, but it is still in the "trial" stage. We have very high mineral content in our ground water, and the OEM filter got real crusty over time. I suspect that this filter will perform at least as well as the original.
