After 2 years of field use,I wanna show you my preferred water filter for quick,clean drinking water while hiking. It's both a 20oz bottle plus filter. It's simple,no moving parts. You can die from severe dehydration but even being super thirsty while hiking can cut your adventure short. I've used the sawyer,lifestraw,Renevo and hydroblu straws. I've found it difficult and a pain at times needing to get my face 6" away from a water source,they also can't fill a container to save for later.
