Camping water filters: Bunnings vs outdoor specialist – what to buy
Searching for a water filter Bunnings stocks is a natural first step. It's a one-stop shop for the weekend, and plenty of campers grab their gear there. But when the water in your bladder is the only thing between you and a bad stomach bug, it pays to know what you're buying. In this comparison guide, we explain what to look for in a camping water filter, how a hardware store and an outdoor specialist differ, and which gravity systems we'd recommend.

Bunnings vs an outdoor specialist
Bunnings is great for hardware, tools and general camping basics, and it's easy to pop in on the way to a trip. Its range of camping gear, including any water filter Bunnings carries, can vary from store to store and over time, so check what's on the shelf before you rely on it.
An outdoor specialist like PAST Outdoors focuses on one thing: gear for people who spend time outside. That usually means:
- A deeper range of filters, purifiers and spare parts, so you can compare options side by side.
- Product details you can check, such as filter pore size, what the filter removes and how long it lasts.
- Advice from people who use the gear on real trips, not just stock it.
Whichever shop you buy from, the checklist below is the same.
What to look for in a camping water filter
- What it removes. Look for a listed pore size (0.1 micron is common) and clear claims for bacteria, protozoa and microplastics. Viruses are a separate question, since most filters don't list them.
- How it works. Squeeze filters are light, while a gravity water filter does the work for you. For groups and base camps, gravity wins.
- Capacity and lifespan. A bigger bladder means fewer refills, and a listed filter life tells you what it'll cost over time.
- Maintenance. Check how it's cleaned and whether spare parts are available.
Why a gravity water filter suits camping
A gravity water filter is the easiest way to filter water at camp. You fill a bladder at the creek, tank or tap, hang it from a tree or awning, and let gravity push the water through the filter. There's no pumping or squeezing, which makes it ideal for families, groups and caravan trips. The trade-off is that gravity systems are bulkier than a pocket-sized squeeze filter, so we'd pick them for camp rather than for a fast and light day walk.

The kit includes a cleaning plunger, a cleaning coupling and a gravity hose with adapters, and the MINI accepts a push-pull cap so you can turn the flow on and off.
Best for: groups on a budget. Keep in mind: it doesn't list virus removal. Read our Sawyer Mini vs Micro Squeeze vs Squeeze guide to see how the Sawyer range compares.

Frequently asked questions
Does Bunnings sell camping water filters?
Bunnings stocks a range of camping gear, but what's available can vary by store. Check the product details for pore size and what the filter removes before you buy, and compare it with a specialist range like ours.
What is the best camping water filter?
It depends on your trip. For groups and camp, a gravity system like the Sawyer Gravity or LifeStraw Peak Gravity is hard to beat. For solo hiking, a lighter squeeze filter is usually a better fit.

You fill a bladder with water, hang it up high, and gravity pulls the water through the filter and down a hose. There's no pumping or squeezing.
Do camping water filters remove viruses?
Viruses aren't listed on the product pages for the Sawyer Gravity or the LifeStraw Peak Gravity systems. If virus protection matters, add purification tablets or use a purifier.

The LifeStraw Peak Gravity 8L filters up to 8 litres at a time, which suits families, caravans and base camps. The Sawyer Gravity is a budget-friendly option with a 1-gallon bladder.
