Odd question, but its on my mind. If i pee into a bowl, and use the filter on that, will it taste like water or pee?

Salt and urea, along with various other substances your body is trying to eliminate, will remain in the filtered urine so it will still taste like pee (whatever that tastes like.) In a desperate survival situation, many people have resorted to drinking their urine. That is ok up to a point. As your dehydration increases, your urine will become increasingly concentrated (dark and even viscous.) It's best to drink urine early in your survival situation since it will be less concentrated and consequently less toxic. That way you are conserving what water you do have longer. Of course, most people will completely exhaust their water supply before they resort to drinking urine. However, drinking highly concentrated urine is probably worse than not drinking it at all. Also, urine is actually sterile inside your bladder but not as it flows through your urethra. Happy drinking!

I am a bit confused... Does the shelf life of 5 years begin after first use? Or 5 years even if unused? Does it have a manufactured date on it? If we don't use them do we need to replace them every 5 years?

5 years from manufacture date which is supposed to be printed on the packaging . Last ones I bought from Amazon were expired but the manufacture and expiration date had been removed from the packaging . I contacted lifestraw and according to the batch #,they mistakenly left, they were 7 years out of date . If you go to your local caming or sporting goods store you will see they clearly DO come with a manufacture,expiration date and batch # . Remember you get what you pay for and trying to save a few dollars purchasing from sellers that arent exactly honest and sold you a unuseable,expired product isnt a good deal in the end. If it doesnt have a date you can find on the packaging then its most likely been removed and either out of date or close to .

Can you use it with sea water the LifeStraw

No, the Life Straw does not remove salt from ocean water. You can buy desalinators on Amazon for around $250- $300 that can make drinkable water from salt water. Unfortunately, Life Straws cannot remove salt or dangerous chemicals from contaminated water.

It says UP TO 1000 liters, since you're not measuring your water and it depends on how bad the water is, how do you know when it has reached its limt?

Take a 1 liter jar, fill it with water, now draw out the water using the straw a mouthful at a time. Count how many mouthfuls you get from a liter of water. Multiply. that by 1,000. Men, women and children will have different figures.
