The Platypus is a high capacity filter for groups of campers or emergency preppers. It’s a bit overkill for your average camping trip, but if you’ve got a huge family or you’re stockpiling your emergency supplies, this is a good option. It meets EPA/NSF standards and handles over 99.9% of viruses, bacteria, and protozoa. The simple gravity style filter can produce about four liters of water in about 2.5 minutes. There’s no need for a separate storage container, so you can continuously filter water as you need it. Dirty water goes in one container and moves to the clean container.
It requires suspension, so it isn’t for on-the-move use. However, for high capacity, this is a good option. It filters up to 1,500 gallons, which isn’t the highest on our list and weighs about 11 pounds.
Who it’s for: Large groups and families.
