Product review (5 stars): Exact Replacement
This is the first time I have replaced the PermaWick element in my Hunter Humidifier. My original one was dropping a lot of aluminum every time I handled it during cleaning. This filter fit right into the carrier frame. There are no instructions with the filter so the only issue was determining which end of the filter goes to the top. Apparently there is a proper direction for the "louvers" in the element to carry the water. The black stripe or mark should be facing up. I also found that I needed to rinse out the humidifier after a day or two because the water in the base was discolored which I assume is from the new element. Other than that it seems to work fine. I even think that the unit is putting moisture into the air more quickly as the unit is shutting down more frequently.
