Stupid things people do on the internet

Urine might not be an especially healthful or tasty beverage, but it filters out pretty much every infectious agent, so drinking urine through it should be reasonably safe, as long as you're not using urine as your only source of water.

I have nothing against the straw itself.
The point is those idiots were drinking piss, water contaminated with feline shit etc..
Vat19 commercial was even more disgusting with them drinking dirty river in a city. While stating that this straw filters it.

Oh, my mistake. The basic LifeStraw doesn't block viruses, which can be present in urine.

The LifeStraw company has other products which have different functions and confusingly similar names. The LifeStraw Family and LifeStraw Mission have finer filters to catch viruses and use hand pumps.

...and I have it wrong again. The more effective models are gravity fed.

removing chemicals from water is serious process. you don't need to do it hiking through the woods, you just need to protect yourself from dead animals and shit upstream

it's not meant to be a widespread solution to all water problems it's just supposed to be a "don't drink bacteria from shit-contaminated water" solution

Urine has too many dissolved salts to be potable. Kinda the same as drinking salt water.

If you're living in NorthAmerica you shouldn't have to worry about viruses in water sources. Of course during a flood sewage flows everywhere and there are viruses in that.

chemicals can easily be removed with activated charcoal

In a flood situation like Houston I think the best water filtration is a multi stage system as you can never be too careful.
1) sock or cloth to remove sediments and large particles
2) mesh filtration such as sawyer filter or lifestraw (meme filter BTW) this'll remove protozoa and bacteria but smaller sized viruses will get through
3) activated charcoal to remove dangerous chemicals
4) chlorine tabs or lugol's iodine drops to kill viruses
