There was no expiration date (I think that is what you are referring to) on the box. We used it already and it was perfect!

There is an expiration date. I used a different brand once and made sure I got this one again. It also looks different

3M puts an expiration date on these filters. The date is a few years out. But, there's nothing in this filter that's going to really expire. It just filters out particles. After opening, it should be stored in a clean location. I leave mine to air out for a while before placing into a plastic bag, so moisture isn't trapped inside the filter.

I couldn't find an expiration neither on box nor vacuum sealed packet. Hmmm.

It depends on when it was bottled, maybe you can ask seller about the expiration date.

I don't see expiration date, but I do see the packaging has copyright ©2012. I can tell you when it runs out if you want.

I can't say that it ever occurred to me that it could expire. It's a good thing to know. Sorry

Not on mine; I have turned it every which way and don't find any expiration date. And yes, it is very, very effective!

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

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.

The expiration varies. They last well over a year however. Be sure to store in a suitable location. Hope that helps.

I asssume the expiration date of the cartridge is as medicines. If you keep your cartridge sealed until you are ready to use there is no problema at all. I´ve seen the dates but always used before expiration date.

I've never noticed an expiration date on it. I can tell you that with the small amount that I use each time, mine lasts well over a year and still works great.

I don't remember looking for/or wondering about an expiration date; my product never had a chance to expire, I used it all up!
