I recenty bought some 'Life Straw Personal Water Filters' for my bug out
However I heard that they can't completely clean your water
Instead you should use KMnO4 to do a complete clean up
Can someone help me out and tell me how I can combine the two things
The Lifestraw seems very self contained and I dont want to break it open
Should I knock up my own secondary filter with the KMnO4 or just add it to the water source?
KMnO4 sounds kinda toxic
Cheers
