Platypus GravityWorks High-Capacity Water Filter System for Camping

10 Best Camping Water Filters for Your Next Adventure

If you plan to go on an outdoor adventure any time soon, now might be the best time to invest in a good camping water filter. Water from natural sources, such as any river or streams that you encounter on your hike, may contain bacteria and other organisms that can make you sick. 

Contaminated water can cause several life-threatening diseases such as diarrhea, typhoid, dysentery, and cholera. Globally, diarrhea alone is responsible for around 485,000 deaths every year.

Editor’s Choice: Platypus GravityWorks High-Capacity Water Filter System

The Platypus water filter might take a while to filter the water, but it is the only filter that requires zero effort when it comes to the filtration process. That is why this filter is our winning pick from the list. 

Platypus GravityWork does not require you to pump the filter or suck through straws to get clean water. You can sit back and relax by the campfire while gravity works its magic and does all the work for you. It is the best water purifier for camping. 

Another convenience of the GravityWorks filter is that it can filter up to 4 liters of water in a single go. The alternatives available have a much lower capacity in comparison. So, if the volume of water is crucial to you, like it is in larger groups, then GravityWorks is the filter to go for.

A Quick Guide to Buying A Portable Water Filter

Choosing a water filter for yourself can get confusing, especially if it is your first time buying one. Before you invest in a portable water filter for yourself, there are some points that you should consider. The following is a quick guide to help you with this:

Is the Higher Price Point Justified?

Before buying, you should consider the cost associated with your hiking water filter. The items on our list range from $14 up to $65. The higher cost does not always guarantee a better-quality filter. 

For instance, the MoKo Portable Water Filter, a mid-range priced product, filters up to 660 gallons of water in its lifetime. This is impressive compared to the more expensive Katadyn Filter, which has an expected life of only 200 gallons. 

Pore Size Matters

The pore size indicates how small the particle that you want to filter out of the water is. The smaller the pore size, the better the filtration. Moko Portable Water Filter, Survivor Filter PRO, and Etekcity Water Filter Straw are the only ones on the list with a pore size of 0.01 microns. The other filters in the list have between 0.1-0.2 micron pores. 

Straw vs Pump vs Gravity

There are three basic types of water filters, and one type cannot claim to be better than the other, as it is a matter of personal preferences. If you have a smaller budget, the straw filters, such as Etekcity and Membrane Solutions filters, will be less costly. 

With that said, the cheaper alternatives do come with a catch. Once the filter on them reaches its useful life, you would have to buy the product again instead of replacing a component. 

Easy to Carry Filters

With so much moving around in your travel adventure, it makes sense to buy a filter that is easy to carry and does not have many unnecessary components attached to it. 

There is often a trade-off between the filter capacity and the associated ease of carrying it around. Filters such as the Platypus GravityWorks may have a capacity of 4 liters, but it is not exactly the most portable one on the list. On the other hand, the MSR Trailshot is a pocket-sized, lightweight filter that you can use to pump water directly into your mouth or store in a bottle. 


The pump filters may have a longer lifespan compared to the Straw ones, but on long trips pumping water can be challenging. Since the straw filters allow direct use, they are easier and faster. 

The Platypus GravityWorks Filter lets you enjoy the scenic beauty while gravity does its job. However, you should consider that this process takes longer than your basic pump or straw filter. GravityWorks takes approximately 2.4 minutes to filter one 4-liter bag of water, making it ideal for larger groups. 

The Added Burden

The last thing you would want on a lengthy hike is the added burden of a 20-ounce camping water filter. The weight of the water filter is an important consideration you need to make before buying. The design of the product and its capacity plays a huge role in its final weight. The products listed above have a wide range of weights from 2 to 16 ounces. 

A heavier hiking water filter, such as MSR MiniWorks EX Microfilter (16 ounces) would be okay for camping, but could get unmanageable for hunting or a long run in the woods. For activities that require you to always be on the go, a lighter filter such as Sawyer Products Squeeze Water Filtration System would be better suited. 

Frequently Asked Questions (FAQs)

Can a filter remove viruses from the water?

As viruses are smaller than the average pore size of water filters, they can easily pass through the filter into your drinking water. To combat viruses, you need to use a Water Purifying agent along with your water filter. 

How to clean Portable Water Filters?

Every water filter comes with a user guide that explains the cleaning and maintenance of the Water Filter. Most filters require you to simply clean them by running water over it or by backwashing (pumping water backward through the filter). However, it is crucial to let it dry first before you store it.

Which is the best portable water filter for me?

The answer to this question depends on every user’s personal preference. Feel free to compare the features of every filter and decide which one fulfills all your needs.

What do hiking water filters remove from water?

Water filters remove any large contaminants such as sediment, metals, and chlorine from the water. Most filters can also remove bacteria from the water. 

When to replace your hiking water filter?

Every filter has its own estimated life. The estimated life also depends on its frequency of use and the condition of the water that is filtered. On average, you may replace a water filter after filtering up to 500 gallons of water.
