If your filter bottle can’t filter viruses, your water isn’t clean
Outdoor water contains viruses that most filter bottles do not filter. The same lake that you drink from animals drink from. And poo in. Common waterborne viruses found in outdoor water include Norovirus and Hepatitis A. Most portable water filters promise clean water but do little to filter viruses from your drinking water. Water with viruses floating in it is not clean water. The best water filter for hiking, camping and backpacking is a water purification bottle that can remove all dangers, including dangerous viruses. Water-to-Go water purifier bottles are lab-proven to filter viruses.
