Lesson learned: always read the package before you throw down the cash! I hope you didnt pay more than $40 for that filter, otherwise return it if you can.
Always read the filter specifications, it really will make a difference.
For your filter, it would only protect you from what it says, bacteria like giardia. it would be good if you found a clean body of water out in the woods, like on a camping trip.
But certainly not suitable for water with signs of chemicals in it, bodies of water next to a farm, city pools, and decadent murky puddles of horseshit soup.
There are filters out there that can block viruses, and maybe even chemicals, but they are more expensive. if your willing to pay for convenience, go for it. Otherwise, with your filter, avoid chemically contaminated water, and boil what you filter from your device to kill any straggler bacterium and viruses. And your set!
