How to choose a water bottle with filter
Think about where you'll use it and how much you want to carry. For Australian creeks and tanks, a filter that removes bacteria, protozoa and microplastics is a solid choice. For overseas travel or water you're unsure about, look for a purifier that also lists viruses. Not sure whether to choose a bottle or a stand-alone filter? Our guide to water filter bottles vs portable filters explains the difference.
Sawyer Micro Squeeze 750 ml: light and long-lasting
The Sawyer Micro Squeeze with a Cnoc Premium 750 ml pouch is one of the lightest ways to carry a filter and a bottle in one kit. Weighing just 96 g with the filter, it uses a 0.1 micron hollow-fibre membrane that is listed as removing 99.99999% of bacteria, 99.9999% of protozoa (including Giardia and Cryptosporidium) and 100% of microplastics. Sawyer lists the filter life as up to 100,000 US gallons.
- What's in the kit: the Micro Squeeze filter, a Cnoc Premium 750 ml pouch, a cleaning coupling and a cleaning plunger.
- Use: drink straight from the filter or squeeze the water into another bottle.

Katadyn BeFree Soft Flask: fast flow, better taste
If you're sick of slow filters, the Katadyn BeFree Activated Carbon Filter Soft Flask is worth a look. It has a two-stage filter: a 0.1 micron EZClean hollow-fibre membrane (listed up to 1,000 L) that handles protozoa, bacteria and microplastics, followed by a replaceable activated carbon stage (listed up to 200 L) that improves taste and odour. Flow is listed at up to 2 L/min.

It holds 710 ml, weighs 450 g and is listed as removing 99.99% of viruses, 99.9999% of bacteria and 99.99% of protozoan cysts. It also uses activated carbon to reduce chemicals, pesticides and odours, and lists lead, arsenic and chromium among the heavy metals it removes.
- Standards: independently tested against NSF/ANSI Protocols 42 and 53, and the page also references the EPA guide standard for microbiological purifiers.
- Cartridge life: 350 cycles, or 250 L. Replace it when press time reaches about 25 seconds.
