“Fantastic water bottle/fantastic price”

“I use this product while backpacking, just fill the bottle in the nearest stream or pond! It was the prefered filter on the trip. Everyone else wanted me to squeeze the water from my bottle into theirs...no Iodine tast like the Hiker Pro filter. I also use it for drinking waster at home because my city water is disgusting. When traveling I take it along so I don't have to buy bottled water. Only one problem, I dropped it and the filter broke...where do I buy replacement filers?”
