About Waterdrop Gravity Water Filter Straw, Camping Water Filtration System
Overall Feedback:
80% positive
79% praised for its long-lasting durability, while 21% experienced a shorter lifespan
The filter system worked flawlessly when we used it with fresh water from the glacier-fed lake with seven people.
I returned the product because of a major flaw in its design for use as a titular gravity filter. The straw clean-side opening was not conveniently aligned to the storage container.
After just one fill, the filter started to clog and came to a slight drip after the 3rd bag. Backwashing didn't solve the issue.
I had difficulty using the tube clip due to my age and lack of nimbleness.

I found the product easy to use and compact. It also enhanced the flavor.
The filter is easy to use, packs up small, and improves the flavor of our water.
I suggest removing air from the filter when connecting it with a gravity bag to ensure smooth water flow.

76% liked its lightweight and compact design
Having this filtration system prevents me from carrying extra bottles of water, which would be too heavy. It makes it easier for me to refill my water containers.
Having this filtration system prevents me from carrying extra bottles of water, which would be too heavy.
I suggest putting the straw and hose in the bag to reduce carry weight.
82% praised for its fast water flow rate, while 18% found it slow
I can fill the water tote with 3.5L of water and the filtration process is quick.
Attaching the line and filter after filling the bag to 1.5 gallon mark makes it easy to use.
The filter has a slow flow rate.
To ensure smooth water flow when using a gravity bag, remove air from the filter. Otherwise, the water flow will be slow and in droplets.
I tested the puribag on very muddy water from a local park and it was amazing. It removed all the dirt/junk from the water and collected it at the bottom of the bag.
