Is there a portable water filter product (for backpacking), like the following two...
MSR AutoFlow Gravity Filter by MSR, which seems to filter relatively large volumes of water (~4 Liters) quickly (~1.75 Liters/Minute) and is portable (299 Grams), but does not seem to filter fluoride and chlorine.
Seychelle 28 Ounce Flip Top Water Bottle with Advanced Filter, which seems to filter fluoride and chlorine and is very portable, but does not seem to filter large volumes of water at a time, it requires sucking with one's mouth through a straw, and it is energy-consuming, it is time-consuming.
...but a product that is a blend between the two and/or shares its good features?
- filters fluoride and chlorine.
- filters quickly (~1.75 Liters/Minute)
- filters easily (does not require sucking with one's mouth) - a pump is acceptable, gravity is better.
- filters relatively large volumes of water (~4 Liters)
- is portable (< 1 pound)
I'm looking for a clean water solution for when backpacking through city and nature for varying lengths of time. I've read mixed reports about the purpose/effect of fluoridated water for/on human health, and I want to be able to filter out the fluoride.
