what is the shelf life of this filter before use?

Our 2nd stage antibacterial activated carbon filter (GAC) actually has a infinite shelf life. It will keep its pore structure and, hence, its absorption characteristics until the activated carbon is put in contact with compounds that can be absorbed. But the special 1st stage hollow fiber ultra filtration membrane tubes have a 2 year natural life span, so overall the H20 Survival Straw has a 2 year shelf life. We recommend keeping it dry and in the sealed bag it comes in until you are ready to use it. After first use it is recommended that the filter be maintained by back flushing it out with the included plunger. After it dries out, it should be stored in the sealed pouch as detailed in the accompanied users manual. By caring for it this way you should expect to get a minimum of 1 years full use,after 1st use.

It is undetermined. The filters that come with the system have a ceramic exterior, and inside the filters you have activated carbon beads. The housing of the system is totally stainless steel with a few plastic pieces. The shelf life of all the materials would be well in excess of over 100 years. With that in mind, it is undetermined how long the shelf life could be.

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 work in the lab thats why i can check the quality of my water from this filter. In my community this filter can last for 4 years. By the way I have a pre filter connected to this unit. The life of the filter is subjective to the water quality and your usage. Take an optional water quality testing.

I've been using mine for 6 months and haven't washed the filter yet...oops. It hasn't seemed to need it though.

It depends on the quality of the water being filtered. If the water is murky, the filters will need to be cleaned more often and may last only one year. If the water is clear, the filters may last up to four years.

I don't see a date. It is a charcoal filter however, so I'd imagine that as long as you kept it sealed up air-tight that it would remade good for a very long time.

Yes, but only 1 if I recall correctly. A single filter should last about 3 months.

I read that the shelf life is 1 year after the time of manufacture. There should be a "Best By" date stamped on the canister.

I bought a spare filter with it in December 2012 but have yet to use it. Note that I use the device daily n live in a especially polluted place.

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 would assume that if you have the prefilter and a chemical filter, you'd be good to go. I can only assume that the chemical portion does not have a shelf life, otherwise they'd have stated so. I've used mine only briefly, and am well satisfied. It's been used where there's a hint of sulfuric acid mist (anodizing) and it has been up to the task.

The pre-filters seem to last about 4-6 months. We have dogs and that may affect filter life, although they may be on an automatic countdown timer.

We used it right away so can't tell you about shelf life. I suggest contacting the company. Sorry.

I have had mine for a little over a year with no wear and tear. I wouldn't be surprised if the filter lasts for another 2 years. I put it through its paces, using it every other day for a few mins and for extended periods while cleaning once a month.

I don't have the product literature in front of me, but usually these things can go 3 months or so before the filter is changed out, especially if the water is kept clean. Filter longevity will depend on your water and how much stuff the pets might drag into it.

From amazon I think I've read 1 year, from another website that sells the same filter I've read 1-2 I guess it depends how much you use it. Hope this helps!
