The Best Backpacking Water Filter For Backcountry & Thru-hiking Use

Whether you are backpacking or hiking, it’s vital that you have access to clean water during your travels. As you can imagine, a lot of physical exercise will mean that you become dehydrated quickly, and so you will need to replenish that lost water from your body.

Instead of lugging around several bottles of water with you or opting for a Camelbak, a water filter makes it easy to ensure that places like lakes, rivers, and streams can provide you with guaranteed clean drinking water.

While many sources of water are clean, it’s impossible to tell for sure just by looking at it. With that in mind, it’s crucial you have the best backpacking water filter with you on your travels to eliminate any doubt. The trouble is, how do you know which are the best ones on the market?

To help you choose the right one, we’ve carried out three water filter reviews suitable for hikers and backpackers just like you! The ones we reviewed are the Survivor Filter PRO, Katadyn Hiker Pro, and MSR MiniWorks EX.

1. Survivor Filter PRO – Cheap and good for occasional use

The Survivor Filter PRO features triple filtration: two cleanable membrane ultrafilters (hollow-fiber) that are capable of filtering down to 0.01 microns, plus a replaceable carbon filter for filtering larger particles.

Independently tested by Intertek Labs in Columbus, Ohio (with the results publicly available to view online), the Survivor Filter PRO can remove up to 99.9% of viruses, staph, and bacteria from the water. According to the manufacturer, it can also reduce any heavy metal content in water by as much as 99.5% for mercury and 93% for lead – something they say exceeds EPA standards for water filters.

It can filter up to 500 ml of water per minute and comes in a compact size at just 6.5 inches (16.5 cm) long. The Survivor Filter PRO can be used in three different ways: direct from source, pumped into the cup, or pumped into a portable hydration device.

Real-world tests have shown that the Survivor Filter PRO works well not just in lakes, rivers, and streams, but also ponds and other bodies of water that are inhabited by local wildlife. Having said that, it cannot be used with water sources that are mixed with chemicals like chlorine.

Pros:

  • It weighs just 10.5 ounces (300 grams) and is less than 7 inches long
  • Filters out viruses, staph, bacteria, giardia, protozoa and water parasites
  • Replacement filters are readily available, cost around 10% of the filter’s price
  • Comes with a handy carry case that takes up little space in a backpack
  • The ultrafilters are good for 100,000 liters of water and can be easily cleaned

Cons:

  • Can be slow to filter water at just 17 ounces of water per minute
  • The pump handle feels like it could easily break in extreme cold weather conditions
  • The included cup isn’t that big
  • Filters can sometimes get clogged up too quickly
  • Only really suitable for infrequent hiking and backpacking trips (i.e. 1-3 times a year)

The Survivor Filter PRO is the cheapest of all three filters reviewed, and in some ways that shows through the quality of some of its components. Having said that, the manufacturer does offer a lifetime warranty in case any parts get damaged because of manufacturing defects.

Overall, it’s a reliable water filter for the odd hike each year. But, some people might find the filtering speed and build quality of the Survivor Filter PRO an issue if they need to use it on a regular basis.

 

2. Katadyn Hiker Pro Microfilter – Good value for money but doesn’t filter viruses

An 11-ounce water filter, the Katadyn Hiker Pro is the mid-range product of the three filters reviewed here. Each active carbon cartridge used with the product can filter approximately 300 gallons or 1,150 liters of water and claims to remove all sediment, particles, and microorganisms from fresh water sources.

Included is a 0.2-micron glass fiber pre-filter, and it can easily attach to hydration packs that have 1/4” drink tubes. It also works well with water bottles too. The Katadyn Hiker Pro boasts a filtration rate of one quart/liter per minute, equivalent to around 48 pump strokes.

The Katadyn Hiker Pro claims to remove bacteria, protozoa, cysts, and algae from any fresh water source. However, it cannot remove viruses like the Survivor Filter PRO due to the larger 0.2-micron filter.

Pros:

  • A mid-range water filter that comes in a compact form
  • Features a quick-connect system, making it easy to attach and remove hoses
  • Includes a cleanable filter screen that extends the cartridge life
  • Can pump enough water for 6-8 people in just 10 minutes
  • Sports a robust design that takes up little space in a backpack

Cons:

  • Replacement cartridges cost more than half the price of a new Katadyn Hiker Pro
  • The inlet port can easily break when removing the plastic hose
  • Can be time-consuming to disassemble and clean after use

The Katadyn Hiker Pro Microfilter is a mid-range water filtration system from a well-known brand. It has a better overall build quality than the Survivor Filter PRO, but replacement cartridges are expensive, and it doesn’t filter out water-borne viruses.

3. MSR MiniWorks EX – the best overall product on test

The higher-end of the three products reviewed is the MSR MiniWorks EX. Developed as a premium product, the manufacturer states that it got engineered for heavy use and utilizes the Marathon EX carbon/ceramic filter element.

With a flow rate of 1 liter per minute, the MSR MiniWorks EX weighs 1 pound or 456 grams. Although it’s the heaviest of the three filters featured, it also serves as a measure of robustness and reliability.

It features a 0.2-micron ceramic/carbon filter and is effective against protozoa, bacteria, chemicals and toxins such as chlorine, and other particulate matter. The MSR MiniWorks EX meets NSF Protocol P231 for removal of bacteria (99.9999%) and protozoa (99.9%) in poor-quality water.

Because it’s a premium product, it’s also the most expensive of the three filters reviewed. Still, when you need to use a water filter in demanding environments, it pays to use the best products on the market.

Pros:

  • A well-built filter with a cartridge that is good for approximately 2,000 liters of water
  • Can be cleaned without the need for any additional tools
  • The carbon core eliminates any unpleasant odors and tastes from filtered water
  • Can also be used with water affected by pesticides

Cons:

  • It’s the most expensive of the three water filters reviewed
  • It cannot filter out viruses
  • Replacement cartridges cost 50% of the price of a new MSR MiniWorks EX
  • Air intake valve needs adjusting before each use

The MSR MiniWorks EX is ideal for hikers and backpackers that need a dependable and compact water filtration system. It’s a little heavier than the other two filters featured but is designed to work well for those that need to frequently filter water.

So which is the best backpacking water filter of these three?

Each of the products in these three water filter reviews is aimed squarely at particular segments of the market.

The Survivor Filter PRO is the cheapest product and has independent testing to back up its claims, but the main downside is the build quality. Still for occasional use or emergencies only this could be a good option.

Meanwhile, the Katadyn Hiker Pro is a mid-range product that offers better construction quality and is quicker to filter water. However, care must get taken when removing the inlet hose, or the port will get broken off. Overall a good product but not the best on test.

Last, but not least, the MSR MiniWorks EX offers exceptional build quality and is popular with those that go on many backpacking and camping trips. Better construction does come at a price but nonetheless this is the best backpacking water filter on test and will last if maintained.

  • The Survivor Filter PRO is ideal for infrequent use and is extremely affordable
  • The Katadyn Hiker Pro is a mid-range product that offers good value for money and can be used a handful of times each year but care must be taken when using
  • The MSR MiniWorks EX is a premium filter designed for pro hikers and those that frequently go backpacking that don’t mind paying a little extra for a higher quality item
