Is there a shelf life for this if it's unused?

Shelf life on the filter is 2 years if kept in a cool dark area. 3 years if kept at these proper conditions and the unit hasn't been dropped or damage. Damage may cause the filter not to collect all of the bacteria and hazards of water collection. I have put mine in a mylar sealead bag with all air vacumed out. This may extend the shelf life. It's worth the try due to the cost. That is just my way of thinking.

the package says it has a3 year shelf life but they never had it on the shelf long enough to see how long a life it has. but I would assume because it's all plastic pieces and everything it would last for a while more than three years

From the company: "LifeStraw personal does not have a shelf life. The LifeStraw Family is rated for 3 years after use."

On the next packaging run, the shelf life comment will be removed. A short shelf life was stated on original packaging as the product was designed for the high temperatures and stress of the African environment. Stored in our homes here in the USA, there's nothing to cause the product to degrade or expire. Direct and constant sunlight will cause any plastic to eventually degrade, which is why the lifespan statement was developed. If you use it for camping and periodically use and store it, it's a good idea to flush it with tap water and allow it to dry before storing.

The package states 2-3 year shelf life depending on conditions. My personal belief is that it will last much longer as long as it is stored in a climate controlled environment... But that's just what I think.

It doesn't need to be refrigerated. I am not sure of the shelf life, but I believe it has an expiration date.

If it is used, it is not listed on the packaging. Best to ask the manufacturer.

I'm not sure of the shelf life, but I am sure if you order it 2-3 weeks ahead of his birthday, like I did it will be fine. Just don't store it in a humid area.

I did not see a "use by" date on any of mine. I can say I'm confident that as long as I store it dry it should be practically indefinite. I have sealed my spares in food saver vacuum sealed bags and will use them with confidence any time in the future when opened. A used filter MUST be completely dry before storage so the two I use I do not expect to last any longer than my other filters (i.e. pump or gravity fed). A food saver vacuum sealer is really a small investment for long term storage requirements.

The shelf life is indefinite. It is inert and refrigeration would not add or detract from it's shelf life.

I don't have an exact amount of time for its shelf life. But in my opinion, it lasts long enough to be satisfactory, whether in a drawer or whether it's been used to glue something. Nothing, as we know, lasts forever.

There is no expiration date listed on the container or in the use/storage directions.

I don't know if there is an expiration. I'm not an expert. If I were you, I would use it as long as it's not separated into fluid and goo.

I really don't know. But I've had a bottle on the shelf unopened for as long as 2 years before I needed it, and it worked fine.

Not exactly sure about shelf life. I don't remember seeing any kind of expiration on the package, so the manufacturer must think it's indefinite. I do know that after a couple of seasons on the bike, they become less effective. You can add more slime, or replace them. What do you mean by having it on hand, anyway? These tubes are heavy and bulky, even when deflated, so I would not recommend carrying a spare while riding.

Yes Definitely when not in use just put back into its original bag reseal it and it should last sometimes up to three months I've had mine I think six months and three of them are still good that have been opened and in jars with material.

Hi everybody! Shelf life is 12 months unopened and six months after opening if stored under cool and dark conditions. I keep it in the original box on my vanity and it's good for a long time.

I just checked. Nowhere on either the box or on the individual cans does it have any kind of a date. No "Use by" or other freshness dates. As long as it is unopened and sealed in the can, it is safe to assume it will last indefinitely (or at least many years) like any other canned goods. After you open it perhaps like paint it might dry out over a period of time but you can check it monthly if you have to.

There is no known shelf life for this product. It should last indefinitely.

It has a long shelf life if unopened. After opening it's recommended to refrigerate and use in three days. My experience when ordering from Amazon is expiration dates almost a year out.

I don't know the shelf life, but yes it needs to be refrigerated after openiing.
