Shelf Life Of Membrane Still In Packaging?

[Keitha333]

Wondering if anyone knows if the 400 gpd Membrane Solutions membranes I purchased this year will still be good next year if left in the packaging unused/unopened. We had a bummer of a season here in the part of Minnesota where I live and I didn't get enough sap to warrant using them. Thanks

I am in the same boat with new unopened membranes, so I too am interested in the answer.

I believe that membranes have a preservative on them. This is why they need to be rinsed before first use. I assume this preservative should give them a somewhat indefinite shelf life. I have some that I bought a year ago that I am keeping in reserve for when my current ones start passing sugar.

As long as they were in a sealed package (and thus never used) and never frozen they should be fine.

I just heard back from the company and they said it should be fine just store them in a cool dry place.

Good to know.
