Access to clean water is vital if you want to stay safe in the great outdoors. A camping water filter will remove waterborne bacteria, protozoa, and viruses and also reduce chemical odors and toxins.

Affordable, compact, and incredibly useful, these water filters can be an absolute lifesaver while you are away from home.

Things To Consider With Camping Water Filters

Because not all water filters are the same, you should consider the following before you buy:


Water Filter Type

There are some really fancy water filters available that promise to turn even the murkiest of river water into something that is clean and safe to drink.

When you are camping, you don’t need whistles and bells, but you do need an effective, reliable filter that’s compact enough to carry around with you. The most popular types of filters for camping are:

  • Straw Filters — These can be used to drink directly from the water source, and they feature a built-in element that filters all the nasties out of the water before it hits your lips. They are lightweight, easy to use, and great for solo trips, but they can be difficult to clean between uses.
  • Pump Filters — These require you to physically pump water from the source in order for it to pass through the filter to provide you with clean, fresh drinking water. An excellent choice for adventures where water may be scarce, the pump function allows you to extract water from puddles and shallow water sources.
  • Gravity Filters — These types of filters need to be hung up high and can get heavy when full, but they offer effective filtration on the go. You simply need to fill the reservoir and wait for it to filter through. Most models come with 2 separate reservoir bags, one for clean and one for dirty water, and with a built-in filter, they can be very effective at removing bacteria and dangerous chemicals from the water.

Flow Rate

The flow rate refers to how fast the water will flow through the filter, and this is usually measured in liters per minute.

A fast flow rate ensures quick and easy access to clean water when you need it the most, although most filters have a flow rate of around 1 liter per minute, which is more than acceptable, even in extreme conditions.


Water Filter Size

Your water filter will need to be small enough to fit in your pocket, backpack, or kit bag. Straw-style filters are long and cylindrical and can be slipped easily slip inside side pockets, pump filters can be a little bit bigger, and gravity filters require reservoirs to work efficiently.

Hot Tip: Generally speaking, larger filters tend to be better quality and will provide you with more water, but plenty of smaller models out there will more than do the job you require when there is no clean drinking water close at hand.

Frequently Asked Questions

How do you filter water when camping?

You can use chlorine or iodine tablets to filter water at a basic level when you’re camping. These tablets can be added to a bottle of water to purify the contents. While tablets are space-saving, a water filter will offer a better way to filter and purify your drink water. They can also handle much more water, and some even have handle pumps.

Are Brita filters good for camping?

Brita water filters aren’t ideal for camping as their primary purpose is to remove sediment and chemicals from hard water rather than filtering unclean water that you’ll come across in the wild.

Is it safe to drink campground water?

Don’t assume that all campground water is drinkable as you don’t know the source. If in doubt, it’s best to use a camping water filter to remove any bacteria or viruses.

How do I choose a camping water filter?

There are several factors to consider when choosing a camping water filter. Firstly, you need to consider what type of filter you need and where you will use it. Straw filters and pumps are great for when water is scarce, and gravity filters are best for when you aren’t on the move as much. It would be best to consider the flow rate and how big and heavy it is to carry.
