Is this membrane shipped "dry" or is it a "wet" pack? I understand that if it's dry it can be stored indefinitely as long as it's in the sealed pack.

Gary, yes it is packed dry so it can be stored for a long time if necessary.

Hi....it is totally sealed. This is a heavy duty apparatus. It's well worth the $.

The supplier says it has a one year shelf life, officially, but is usually fine for a much longer period of time if kept in a cool, dry place. Make sure your seal is in tact upon arrival and if it isn't, let them know, they will replace it. There is no expiration date on the container that I have, though. They are very good at communicating in a timely manner, so if you contact them, you can expect a prompt reply and quick resolution to any concerns.

Sure. I keep some in a container and keep the rest in the bag it comes in. It is resealable. It gonna get messy in the transfer too. this stuff is very fine.

I took it out of the bag and put it in jars. I've stayed sealed, you get a long time out of it.

It has an indefinite shelf life as long as you keep moisture out and the bag sealed as tight as possible.

I've had it for a few months now and, from what i can see, there is no difference between when i bought it and today. You just need to store it in a 'cool dry place' and thats it. Also, i'm not even halfway through the bottle yet so i would expect to it to last to the end of this year.

From my experience, and what I've read online, it's shelf life is indefinite as long as you don't get it wet.

When I called Katadyn with the same question, I was told that as long as the packaging was intact and no moisture was getting to the tablet, the product was viable for a really long time. Considering how well those tablets are sealed, I concluded that I didn't need to worry about shelf life. Also, a tablet can get crushed in the packet and still be fine.

I believe the literature packed with the product says "indefinite" -- like forever -- as long as it remains sealed. For accurate testing, leave the packet open but not in a damp or drafty area for about 48 hours. For a couple months I forgot to start the test on a Thursday morning so I could take it to the post office on Saturday. But as long as it was sealed, it was fine.

what is the shelf life of a toner if it is packed air tight which are the way they are usually shipped???

Good questionBased on my experience these packets should last at least a year - as long as they are stored in a cool DRY space. One of the shipments I got had clearly been exposed to too much moisture and the powder in most of the packets was all caked together in a hard mass.

I've had mine over a year... no problems. Each cartridge is packed in a sealed plastic "bag" that it seems to me would greatly increase shelf life and prevent drying out... but they are also not "open" until you insert them into the machine so I suspect the shelf life is fairly long.

I would say forever? Its air tight and vacuum sealed... my "stash" is always fresh and sticky

Yes it is totally sealed, waterproof where u can submerge it in water. My tank is larger than what it is rated for and works perfect.

It stays very fresh for a long time, as long as you keep the bag tightly closed. I fold it a couple times and clip it. Or you can put it on an air tight container, but I think it stays better in the foil bag that it comes in!!
