Water Bottle with Filter Straw

Combine with a water bottle and filter straw, the 4~5 stage filter with the gravity and squeeze water filter system. It takes someplace in our backpack, and when we drink the water, we need to aspire.

According to the above information, the key to choose a lightweight water filter depends on your needs.

Depend on: Quality of Outdoor Water Source

If you only filter the tap water outdoors, which is generally clear, you don't need a filter system for particles.

If you plan to filter the water from the river,lakes or well which is sometimes not clear, you will probably need a water filter system to remove the particles.

Choosing at least 3 stages lightweight water filter, and if you want to drink pure and clean water, use 0.1 micron filter, because this filter has the capacity to remove bacteris, virus, chemical pollutants, and other particles.

Depend on: How Many People Take Part in the Traveling

If just yourself or 2 people are camping, choose the squeeze water filter, lightweight and portal to bring on your pocket or backpack, and stock normally 300-600ML water with squeeze bag.

If a group of people takespart inhiking, the gravity water filter system could meet the water needs, because it can filter 3-6L water at one time.

Finally, when you decide to buy a lightweight water filtration system, the above information will help you figure out the best one.
