This new system claims to filter more bacteria and virus better than any other portable/carryable bottle,
it's "Ultra Filtration" What's the point of drinking water if it's got bacteria or virus in it.
Until recently you've had to use chemicals (pills/power/other) in conjunction with the bottle filters to
have very safe, clean water. Many people don't use the chemicals and take chances,
and many get sick or worst.
They've had problems finding a way to get it as close to 100% safe/pure as possible; that's easy to use,
lasts long, is portable and is reliable. They do have base camp systems that can do it but they are
not portable, and they take longer to filter.
Also nalgene bottles are bad for you too!

their saying now.
So yes you can get nalgene bottles with charcoal filters and such like your links but they are not as good.
