Hi. want to know how long do these canisters last. What is the expiry period for these canisters?

We usually buy 48 at a time. It takes quite a while (at least a year) to get through them and we have never had any issues.

I bought my 24 pack probably over 2 years ago & it still works. I've never had any problems with these chargers since I started making whipped cream in the late 90s!

I'm not sure...my canister says 11.0. The exp date is 7/2015. Sorry I'm not much help!!

I asked the manufacturer this same question. They said as long as the filter passes the blue dye test, then it is still good to use. Filter life is not a matter of time, but rather media integrity. They would not predict a shelf life related to time. Said "always test the Cannister using some blue dye in the water, before using for drinking purposes". I have a canister over two years old that is still good.

I see no expiration date on my bag of 250 packets. I am no expert, but I do not see why they would ever expire - they are in foil packets (that should keep any moisture out) and they are just salts that I think should last forever. Plus, it is the best deal on them by such a big margin, I would get then that way even if I was not sure I would use them up.

I have purchased these for the past 2 years and each time the expirations have been at least 1 year out. You can buy them, see the dates and then send them back if you need to! I have never had an issue with this.

I am sure they have an expiry date on them. You would suspect they would give you a year. Try to contact them.

Not sure about expiration dates, but they work fine and last long - even if left in a drawer for weeks at a time. Great buy, especially if you think how expensive they can be over the counter in a retail store.

Not sure on expiration. None on the container. I think the key is to keep the snug fitting lid on it - especially in dry environments. I made my purchase monthes ago and it is doing fine although I use it regularly.

I would say a few weeks, depending where you put them. If you have them in a rather air-tight container, they last a very long time...if there is air exchange, they obviously won't last as long. I like them a lot but I did have one go bad on me...when I was re-charging...for some odd reason, the balls turned black...rendering that one useless...the others that were in the same condition and were heated for the same time did just fine...

I don't know. I usually use mine within a month or so and they are fine. They are individually wrapped in a "vacuum" type package so I am guessing they have a long shelf life.

They seem to last a long time. I'm working on a supply I received over a year ago. They are in a covered canister and seem to do fine.

The bag(s) we got had almost a year and a half shelf life..but..kept cool..they will last much longer. We have bought these in 6 pound bags SEVERAL times.

Hi - I no longer have the can since I used it up. But I have a similar product made by Dow Chemical called "Great Stuff." On the bottom of the can it says "best if used by May 2114." I have used maybe have of it. Apparently, they can expire, but have a rather long shelf life. That is about the best that I can answer you. I used the Fill Seal for ventilation on my roof because it is, I believe, a little more flexible than "Great Stuff." Hope this helps.

I don't recall Alan expiration date, but i didn't look. I'd say for freshness sake I'd use them asap, but they're vacuum sealed so they should last a while if not opened.

I don't expiration is an issue. I have never had a problem with them. They work great.

Don't know specifically, but they last a long time, we use ours every day and only change the canister maybe once a month or so.
