June 10, 2022 | By

We tested the best backpacking water filters and purifiers for your next trip into the great outdoors.

You dont need much to have a successful backpacking trip. Yes, youll need some gear . But most importantly, youll need a way to get clean, safe water while on the trail.

Before we explain in depth how each water filter works, here are a few things that will help you through this guide. There are many different methods of filtering water. The most common methods are through a cartridge or tube, with either activated carbon, UV light, or chemicals.

Filters also come in different styles: straw-style, pump filters, gravity filters, and UV or tablet treatments. They all make water safe to drink but differ slightly in size, durability, and price.

Weve spoken to thru-hikers, put many of these to the test, and read hundreds of customer reviews to find out which water filters on the market are truly the best.

Best Overall Water Filter: Sawyer Squeeze

This water filter system is the gold standard for many thru-hikers and backpackers across the globe. The Sawyer Squeeze filters down to 0.1 microns, making it effective against bacteria and protozoa .

What customers said: The Sawyer Squeeze has over 1,000 five-star ratings. Top feedback from customers includes the ultralight trail weight, the ease of use , and the durability over time.

How Do I Clean A Gravity Water Filter

Three main components need to be cleaned: The hang bags, hose, and filter. All three of these need to be clean for the water to be properly filtered.

One great way to clean the system is backflushing. This is when you use clean water and run it in the opposite direction through the filtering system. When the water runs the other way, it can clean the filter from the bigger chunks that can get stuck. The Platypus GravityWorks system includes a plunger syringe that is filled with clean water and pushed back through the filter from the clean waterside.

To fully clean the filter, clean it out with water and a little bit of bleach to kill any remaining pathogens.

Taking A Family Break From Modern Life Make Sure Your Camping Equipment Is Up To The Job

Modern life can be all-consuming and getting back to nature offers the perfect antidote, but before you head off-grid make sure you have a portable water filter you can trust. Concerns about screen time, a poor diet, too much time indoors, school pressures and the environment, in general, can prove overwhelming for parents.

The immense pressure no doubt helps to account for the popularity of family camping holidays, woodland breaks and the rise in ‘off-grid getaways.’ Getting back to nature is a chance to get away from it all, reconnect with your children and tear them away from their screens.

When planning your escape though, having the right equipment will make a difference. Do you really want to go camping and end up driving out to the nearest convenience stall to stock up on drinks or plastic bottles of water? Or can you be sure about the quality of the water you will have access to onsite?

Everything You Need To Know About Gravity Water Filter

The Gravity Water Filter is a purification method with outstanding benefits and abilities but is not that well-recognized or acknowledged. Especially that there are tons of competitors out there, who are in the same line of business that aims to one-up the other through functionalities and customer satisfaction. However, the Gravity Water Filter is not to be underestimated because it has highly beneficial features to consumers.

We live now in an era wherein everything is made possible. The modernization and development of technologies and machines have skyrocketed throughout the years. This had left us all in awe about how certain things come together and result in something greater than we cannot easily grasp or understand and leave us feeling surprised.

One of the examples that can surprise us with its greatness is the Gravity Water Filter. This article will discuss its different features, how it is helpful to its consumers, how it works, and the best Gravity Water Filter to choose.

Do Gravity Filters Remove Bacteria

The type and quality of your gravity water filter will determine exactly what can be filtered out. The lower-level gravity water filters will focus on chlorine and physical pieces being filtered out. Once you go for the more expensive and high-quality filters, you will be able to filter out more contaminants.

RELATED ARTICLE: How to Purify Water When Backpacking

Water contaminants include many things such as bacteria, protozoa, pesticides, heavy metals, and more. For example, if you look at the Platypus GravityWorks, it removes 99.9999% of bacteria. In addition, it removes 99.9% of protozoa, including giardia, cryptosporidium, E. coli, salmonella, and cholera. No filter removes 100%, so this is about as good as it can get.

Again, removing bacteria is not something that happens with every gravity water filter. But, it is very important to consider bacteria. According to the Minnesota Department of Health, water with bacteria and other pathogens can make you sick. Also, you cannot test the water every time before you drink it. This is where a gravity water filter can come in and save the day.

What Is A Gravity Water Filter

DIY Backpacking Ultralight Gravity Fed Water Filter

Gravity water filters dont rely on water pressure to push water through a filter. Instead, they use gravity hence their name to slowly filter water and gradually remove contaminants. This often means that a gravity fed water filter can do a much more thorough job of filtering water, by giving it longer exposure to filter media.

Platypus Gravity Water Filter Best Overall

The GravityWorks water filter system from Platypus is an all-in-one system that includes the dirty water and clean water bags, as well as the filter and hose to connect them. It weighs 11 ounces in total, which is a bit heavy for this type of system. But were willing to carry a few extra ounces, for the extra ounces that these reservoirs provide. They can each hold four liters of water, so youll be able to collect and filter over a gallon of water at a time.

This filter removes over 99% of bacteria and protozoa, making it a great choice for use on trails. With a flow rate of 1.75 liters per minute, it wont slow you down when youre trying to make miles. You also wont have to replace the in-line filter often since it lasts for 1,500 gallons. In our testing, it turned murky water crystal-clear, and it passed the taste test even when the original source smelled less than pleasant. Overall, we love the fast filtration, large capacity, and clean water it produces, which is why it has earned the top position on our list.

Main Types Of Filters For Camping

The Pump – The standard camping filter uses a pump system to draw water from the source. The pump forces the water through a micro-filter and then the clean water comes out a tube that can be placed in a container or cooking pot.

Gravity-Fed Bag – Another type of water filter for camping is gravity-fed. You fill a pouch with the source water and elevate it or hang it from a tree, allowing gravity to pull the water down through a filter that removes 99.99% of bacteria and protozoa.

The Straw – The other main type of camping filter uses a straw and filtration media. One type of straw filter you place directly in the stream or source water and suck. Water is drawn up through the filtration media providing safe drinking water. You can also get a straw water filter bottle, which is usually more convenient. Both straw type filters are designed for personal use and cannot provide water to fill other containers.

What Are The Benefits Of A Gravity Water Filter

Backpacking Tips – Sawyer Mini Gravity Water Filter

The biggest benefits of a gravity fed water filter relate to convenience, performance, and portability. Simply put, gravity water filters dont require a lot of effort from you.

You can basically fill up the reservoir and let it do its thing. When you come back in half an hour or so youll have clean water ready for drinking and other uses. Contrast that to the filters that require you to turn a crank or work a pump.

Performance wise, its almost impossible to beat a gravity filter. High-end filter elements are capable of removing tremendous amounts of chemical, heavy metal, bacterial, and virus based contaminants.

They can take water that would have seriously sickened your family and make it into pure, clean tasting drinking water.

The last big benefit is how portable they are.

While there are inline filters that provide similar levels of performance and convenience to a gravity filter, theyre all permanent units that require professional installation.

You definitely cant bring them with you if you go out for a longer camping trip and need to set up a basecamp. You also cant use them outside your home if you want to have some water while enjoying the outdoors, as an example.
