The human body consists of 70 % water. Water is an essential part of our everyday life and how much water you need in a day depends on the conditions like temperature, altitude, humidity and the amount of physical activity one does during the day. On average, men need almost 3 liters water and women need 2.2 liters water a day. And if you’re hiking through the mountains this percentage can increase by 50.

There is water available mostly when you’re backpacking or hiking in forms of lakes, streams, snow runoffs etc., but the water contains lots of contaminates in forms of microscopic parasites and bacteria’s. To avoid all this you need best water filter treatment to clean the water of all contaminates and make it drinkable.

Features to Consider

Before making any decision there are a few things that you need to take a look at. Here is the list of few important things.


Everyone knows that why weight is an important factor while choosing a product for backpacking. You have to carry the water filter with you so need to choose a product that weighs less. Backpacking is more pleasant if there is less weight in your backpack. You need to consider that you’ll be carrying other necessary things with you too. Mostly lightest weight water filters are chemical treatments or tablets that take almost no space.

Another thing that you should know is that once you have used a filter on the ground, it’ll get heavier and to remove the traces of the water out the filter gets hard too.
So in order to avoid this, you need to use the filter overnight to remove all the water out.


Speed is a really important factor in a water filter if you don’t want to get into some serious trouble during your backpacking trip. On most backpacking trips, water source can be six miles away, that’s enough of a reason to buy a water filter that cleans water immediately. Straw filters and gravity filters are known to work quicker.


If you’re going to a place where the chance of water source being contaminated by viruses is high, then you need a water filter that eliminates viruses too. Here are a few systems that are known to remove viruses effectively:

  • Iodine treatment
  • Latest Gravity filters
  • UV light treatment systems
  • Chlorine dioxide

Most of the other water filters can eliminate bacteria and protozoa. Virus shield is usually required for international trips.

Reliability is another factor that shows how much you can depend on your product when you’re hiking  your way through the mountains. Whether you  are going to need a backup system or not. You can evaluate the reliability by the maintenance required and how easy or difficult it is.


If the water filter is easy to use that means you will save the time and the energy. If the maintenance method is complex it can take much of your time too. Chemical treatment usually doesn’t require any maintenance, which means less waiting time and it’s convenient to use.

Be wise in selecting a backpacking water filter so you stay hydrated and enjoy more time outside exploring our nation's great outdoors.

In latest water system’s convenience and less or no maintenance is trending.


You need to consider the capacity of the water filter if you plan on going with a group of people or in the case of long trips. Capacity is basically how much water can be treated through the water filter.

Pump filters are known for filtering  never-ending amount of water. Chemical treatment is expensive, but it is mostly effective for individual use.


Though the taste is not such an important factor while choosing a water filter, but there is an obvious difference between these water treatments. Chemical systems change the flavor of the water a little. Iodine is known for awful tasting but that can be avoided by using taste-neutralizing tablets. Chlorine dioxide gives a pool like taste.


Chemical and tablet treatments are usually expensive. Gravity water filter treatment and pump water filters are cost effective mostly. If you are going with a group then pump water filter is cost effective for you.

Here are a few types of water filter system that you must know about.

  • Filter straws: In this kind of water filter, you have to drink water directly through the straw as the name ‘Filter Straws’ indicates that doubles as a hollow fiber filter.
  • Pump Filters: Pump Filters are quite famous and are basically what people think first of a filter this comes to their mind. In this system, the filter in the device has a small pore through which the microorganisms are filtered by pumping the water through it.
  • Gravity Filters: In Gravity filters the water is pushed through the filter by using the force of gravity. It saves you the time and trouble of the pumping process.
  • UV light: This system uses Ultraviolet light to cleanse water, the mechanical device works more efficiently than other because it kills viruses too. Though these products work on charging batteries or chargers.
  • Tablets and Chemicals: In this treatment, chemicals or tablets are added to the water to kill the bacteria and other microorganisms. This product also has the advantage of killing viruses as well.

  • I bought the Sawyer Products Mini Water Filtration System from Amazon last year because of the raving review it was receiving. I am happy to say that the reviews did not lie. It is small and light, so it is very ideal for my backpacking adventures, and it works perfectly.

  • Thanks for the valuable input Grace and I’m pleased that the Sawyer has served you well. It’s a fine product and provides the safety you need without the hefty price tag.

  • MSR’s SweetWater Microfilter looks like something that would fit in with our upcoming camping trip and its price is within my budget too. But before I add it to my shopping list, I need to know if it comes with all the accessories like the brush, stuff sack and bottle adapter.

  • I think it comes with the bottle adapter as specified by the manufacturers. You might want to get in touch with them to inquire about the brush and stuff sack.
