If the filter is not used for a while and is still wet on the inside will it go bad from lack of use between trips?

I have not had that problem. I give it a good ole windmill spin or two and place it an upright position (direction of flow) put the supplied caps back on and what little water is left drains down in the cap area. Which you and dump out after about 15mins. Water tastes great no funky smells. I think the windmill spin gets most if all the water out.

These filters are traps and bacteria will breed fast in a warm, dark and damp environment. Even the holding water tank, must be disenfected during storage. I have never seen this type of filter clear or transparent too give the user some idea of its condition.

We put our filter into our house refrigerator when there will be an extended period of non use. This prevents/reduces and bacteria build up and we've never had a problem. Drain it the best you can before refrigerating.

I don't know. I use it all the time, this is my second one, couldn't really tell when it went out the water just tasted different. I haven't found a way to hook it only to cold water either.

I've personally left the filter unused for a month in summer with no problems. Apparently the charcoal which is a fundamental part of the filter not only helps with water taste but also keeps any mold or mildews from forming.

Hello and I will attempt to answer your question. I believe that there are stages of filtration and that if you clean it properly and let it dry after you've used it then you would be able to use it again. I bought mine as part of my life preservation backpack or more commonly called bug out bag. So even though I bought it some time ago it remains new in the box, life straws, survival food, flashlights, solar panels, knives, guns, bullets, and many other life-saving items. If you're just going camping I would suggest bringing ample water with you. If you're going to be backpacking in basically uncharted territory then this would be a good item to have with you. Good luck and at least know you are buying the best product on the market.

I'm sure eventually the filter might need replace, but these are meant to be rinsed and thoroughly dried, then re-used

KEEP out of water when not using,,,, if your not using it at all at the moment un wrap it , room temp room it will last for years

I do not believe you will have to replace it. The part that removes the bad stuff is a 0.1 Micron absolute hollow fiber membrane inline filter so there is nothing that will get old. Also all you have to do to clean it is back flush it. For the price it is a great filter.

Eventually the filter will need to be replaced. As long as you take care of it it last a long time.

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.

We suggest letting the filter dry as much as possible. You can then put in your refrigerator between uses to help prevent any bacterial growth. Place something under the filter in case some residual water drips out.

FYI, if you drop it hard, which is likely before end of useful life, you should replace it since the filter may be damaged. http://www.princeton.edu/~oa/manual/water.shtml

We recommend changing the filter every 6 to 8 months. However, the filter life will depend upon the environment in which it is used.

air flow through the filter is not restricted when the filter is clean. just remember to clean it every 3 to 4 days to prevent dust build-up

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.

No... this filter cannot be refilled. But you should get atleast a year and a half of use out of it. And you can pull "or" push air through it. Hope this helps....

No! You can wait for months, until it gets really dirty, or wash it after you're done each time. The water exits through the filter after each dunk, trapping any sediment in the filter. After a while, you can replace or clean the filter and reuse.

Yes you still need to replace it. Distilled water is not treated and often is able to grow more bacteria (no chlorine) so your filter can actually become a breeding ground for bacteria that are put into the air should you not replace it regularly.

The filter will need replacing at some point but that could be a year or more depending on use. If you put a coffee filter over the pickup, and if you don't don't filter muddy water the filter will last a long time. This is an excellent water filter! There is a guy on YouTube (Wooden arrows) that does a great review of this filter. Hope this was a help.

when nit's new a long time, till filter does not touch water, then after a few times it doesn't always work, and then not a long time if it does.
