Could the filter be stored and how long? I would like to send my friends more than one so he can change every 6 months

The filters contain mostly activated charcoal - there should not be any adverse effects to storing them for any period of time. I have also not seen a "best by" date on the box.

I just installed one and the certificate was dated June 2008 and I bought it within the last year .. When I pulled the cap I heard a hiss .. so I am guessing it may be back filled with an inert gas .. Along with them being sealed in plastic and yes .. mostly carbon .. I cut one apart after 6 months of usage .. and saw nothing unusual and no mold or anything like that .. I plan on calling 3M and asking the question when I have time .. I will update this post when I get an answer.

I truthfully do not know. I do know that I do not change mine every 6 months. I would think that they last a long time as I have not seen any date on them.

I would not see why they could not be stored.There is no expiration date on the filters themselves, so they should last forever, I would think.

I don't believe there is anything in the filter that would prevent long term storage. I have stored them for over a year with no problem.

As far as I know they can be stored. I have them sent from Amazon on an auto shipment every 6 months.

What is your question? I can't understand why these filters would expire after two or three years if you have not installed them.Perhaps the expiration applies if they've been installed and water has run through them. If you install and let them sit there for three years I can then understand having to change them after two/three year; even if they just sat there unused.

I didn't see a expiration date on the box. So I'm not sure if they have a "use by date". We use the filtered water and ice often (2 people in the household). They last about 6 months. And the savings on the purchase price for 2 filters was not substantial enough to buy more than one at a time. Besides, I always need something from Amazon to add a water filter to the order.

Depends how much water you drink. I guesstimate 2 months. You can get filters on Amazon or Ebay.

I don't know if they can be used more than once, but I wouldn't recommend it. The whole purpose of the filter is to remove taste contaminants in your house water. I suspect that if you used them more than the recommended two months per filter, that it would reduce its effectiveness. Try it and do a taste test. Maybe the rest of us have been dupped into discarding a perfectly good filter !

If memory serves me correctly the manufacturer suggests changing them at a six month interval. I would imagine that would be driven by two things, the capacity of the filter to do just that - filter, and I'm guessing here but perhaps the propensity of contaminants (e.g. mold) to grow on any surface that has become moist. Keep in mind that I am speculating on the second driver. So, if you have a typical family (which I'm sure is what the time frame is based on) I'd suggest changing the filter at Thanksgiving and July 4th, which are easily remembered dates and approximately six months apart. I happen to live by myself so I tend to change mine when I remember (I really should write it down, perhaps on the back of the mirror of the medicine cabinet) but let it go for longer than six months. I can say that I have never noticed a problem. I've had mine for at least four years. And yes I mean the filter head, not an individual filter cartridge. Hope that helps you Jenna.

I believe they're only supposed to last 6 months. Our initial filter lasted that long.

I'd say the two-month time on each filter applies if you're using it a lot, say 5 liters a day. Otherwise, you can keep it for 3-4 months.

They may last up to like 3-6 months, just depends on how much you use the bottle. The filters can be bought right on amazon but I found then at Walmart to be a little cheaper.

The packaging suggested use for 40 hours, or 30 days after opening the sealed plastic wrapping, whichever comes first. My experience was that there was no visible change in the filter during this time. I got a marker and wrote the date on the filter so that I would know when to replace them.

I have read on a reliable site, that the black filters will last indefinitely. However, they said if the filters are going to be stored for long periods of time, put them in a re-sealable plastic bag, so that the filters do not absorb any air born contaminates. Jim Imel

The company that installed my new system said that this filter would last one year. But when they came out to do an inspection after one year, the guy said that I should have changed the filter earlier. I now change the filter every six months. So far, that seems to be about the right amount of time.

I have used it four times in a row. Had to get new filter because of mold growing on it after six months in refrigerator, stored on water. Instructions say to store in water.

There is not. What is basically a reusable sticker comes with it to tell you when you changed it last and when it needs to be changed next. I stuck mine to the fridge which reminds me I should change the filter soon.

Trust me, change it every 30 days if you want the water to be fresh. If you forget to change it for 3 months, it will smell funny and won't be filtering properly. If you have ever noticed a water bowl getting a little slippery inside, think of what a filter after 90 days in water would be like. I got rid of my fresh flow because there were too many crevices that I couldn't get clean enough and it wasn't as fresh as changing out the water in a bowl everyday.

I got them here on amazon. You'd be surprised how long the filters last. I see 10 clue st a day on average and a filter will last me a out a month.

Not by visually inspecting the filter disc, its appearance doesn't change over time. There is a date wheel built into the top of the can, set it to the day of the month you first use it and change filter every 2 months on that day.
