Review: Exactly what was needed. - Fit perfectly in my 3.0 model. Holds water unlike the unit it replaced. This has a green core, stay outdoors away from, or replace, with this unit to breath life into your cigars! Thank you for this r replacement. Works 1000% better.
Review: FOAM REPLACEMENT - The old green foam does not last long. The new white sponge foam is not very functional. Poor replacement so I purchased a brick of green florist foam on desertcart and cut off a section that would fit inside the plastic cartridge which I carefully cut open along the glued seam with a utility knife. The cartridge works great and now it’s very easy to replace the foam when needed at a very cheap cost. After replacing the green foam the cartridge snaps back together. No need to keep buying cartridges that don’t last. Now the cartridge is EVERLASTING PROBLEM SOLVED!!!!!!!

### ⭐ Don't stay wet
*by C***S on December 23, 2025*

Not sure what is happening, but the cartridges don't seem to hold water anymore. I used the first 2 cartridges that came with the Oasis for a couple of years. They would work for about a week before I would switch them. The last 2 I ordered in the past couple of months either don't absorb or don't stay wet more than a day or two. I am wondering if the sponges were just old when I got them.
