D Mam article on the Life straw system

[Prepper1]

Not worth the £30 imo.
it only purifies 1000 liters before dying.

The bleach tablets you can buy in the pound shops are the same chemical composition that the world health organization send to Africa for purifying their water, I checked online at w.h.o.

48 tablets per pack 1/8th tablet purifies a full bath of water about 250 liters....

I even tried drinking the water at massive over dose levels of 1 full tablet per bath full.

tastes like a swimming pool but no ill effects.
