A quality water filter is an indispensable piece of camping equipment when you’re out in the bush or camping at a site that doesn’t have potable water available. There’s also a difference between a water filter and a water purifier. Knowing which one is best for you starts with understanding the risks and identifying the type of water source you’ll be tapping into.
Without proper water filtration, there’s a high risk of contamination and water-borne pathogens in any source of natural water. Even the clearest creek can still harbor dangerous microbes like protozoa, E. coli, giardia, cholera, and even hepatitis. Just to name a few
There’s also a risk of agricultural runoff introducing chemical pollution to a water source or creating an environment in which microbes thrive. A farm miles away that allows runoff from fields and livestock to enter a river can wreak havoc in that clean-looking creek.

What To Look for in a Camping Water Filter
The best camping water filter to meet your needs must be effective enough to prevent protozoa and bacteria from infiltrating the harvested water container. It also needs to have a reasonable flow rate, and enough capacity to get you from one natural water source to the next.
Filtration Method
A high-quality camping water filter will have a mechanical filtration system of .3 microns or smaller to block physical particles and sediment. Most will also have some type of chemical filtration or treatment to neutralize or absorb microbes.
Activated charcoal water filters have microscopic nucleation sites that capture potentially harmful microbes and some chemical contaminants. However, these filters have a limited capacity and need to be replaced and will need to be replaced more frequently in areas of high microbial contamination.

Flow Rate
The ideal flow rate for a good camping water filter is around 1 litre per minute. Any slower than that, and it can take a frustratingly long time to fill a large water tank or jerry can. Anything faster than 2 to 2.5 litres per minute likely has poor physical filtration and there’s a high risk of bacteria and other small microbes remaining in the harvested water.
PRO TIP
If your camping water filter’s flow rate is noticeably slower than it should be, it’s likely a sign of a persistent clog in the filter or the purification cartridge. The wise move is to dump out any recently harvested water, and then either clean or replace the filter apparatus.

Capacity
A good camping water filter needs to have a capacity that’s equal to or greater than the amount of water you’d need to filter and purify in a single adventure. Otherwise, you’ll need to replace the cartridge or filter multiple times, meaning you’ll have to carry those replacements with you on every trip.
Portability & Weight
If you want to use your camping water filter for hiking trips or deep bush camping, then lightness is a top priority. If you’re looking for a camping water filtration system for your caravan, you want to make sure that its dimensions will fit through into the cupboard or container it will live in.
Odor & Taste Removal
Some water sources carry off-putting flavours with them even after being filtered. If this is an issue with the natural water sources in your favourite camping areas, then you might want to prioritize a water filter with activated carbon, or some other type of proactive chemical filtration built in.

LifeStraw Personal Water Filter for Hiking & Camping

LifeStraw is one of the biggest names in camping water filters. This model has a .2-micron filter which will block out 99.9% of microbes. The filter has a lifetime capacity of up to 4,000 litres.
The promotional videos you see for LifeStraw show people drinking directly from dirty puddles, which is far from the ideal way to use this camping water filter. To maximize the capacity of the filter it’s best to draw the water from a hand-dug gypsy well or from a large container after letting the water decant for several minutes.

Conclusion
The best camping water filters have filters with a tolerance of .3 microns or smaller. You should prioritize filters that have the highest lifetime capacity. This makes it easy to use them in the bush without needing to constantly replace the filter. Multi-stage camping water filters and units that have active charcoal canisters in the filter system are also handy for neutralizing odours, as well as off-putting flavours and reducing the risk of chemical contamination.
If you need a camping water filter that fits easily in your pack, then the LifeStraw might be your best option. If you need something that you can use to filter a water dispenser for your party’s campsite, but you can still bring with you in your pack for a day hike, then the Water Drop might be the best camping water filter to match your camping style.
