Why We Like The Guardian Gravity Water Purifier
The Guardian Gravity Water Purifier keeps us safely hydrated on our backcountry treks and while traveling abroad. The high-flow system filters up to 1 liter in 2 minutes, providing 10 liters of drinkable water by the time we've figured out where the smell in our hostel dorm is coming from. It's us. The smell is us.

Bag leaked, flow rate seems slow
- Familiarity:
- I've used it several times
I purchased this right away as I own the Guardian pump version and not having to pump water would be awesome. I feel like the flow rate was very slow, likely due to water having to travel through a much tighter membrane in the purifier cartridge. The main problem was the bag leaked water out of the outlet and I was attempting to test it indoors. They show people using it in all sorts of places, but if you have a leaky bag that will be tough. I repeatedly contacted MSR support and never received a call back. It would have been nice if they were responsive.
