Advantages Or The Benefits Of Buying A Backpacking Water Filter 

Here are a few benefits that you will get for buying a backpacking water filter.

  1. The water filter removes the impurities and wild pollutants like dust, mud, stones, and leaves.
  2. They let you drink clean, refreshing, and dirt-free water.
  3. On the other hand, the backpacking water filters make the drinking water free from bacteria, protozoa, and sometimes viruses.

  7. Besides, the water filters give you the taste of the water from various sources like ponds, lakes, waterfalls, streams, and more.

What Are The Things To Look At Before Buying The Backpacking Water Filter?  

1. Ease Of Use

Drinking water is an essential thing that people do many times a day. Even when you are backpacking in the backcountry or some other places, you need water to survive. Hence, it is necessary to have a water filter that is easy to use. When you have water filters that are hard to use, it might be frustrating for you. That is the reason why we always give priority to simple water filters.

2. Pore Size

In general, the pore size is the length of the small spaces or the openings in a filter. To measure pore size, you have to use a micron scale. When the pore is small in size, it can prevent even the tiniest particles. As per CDC guidelines, to remove protozoa, the pore size should be 1 micron or less. Bacteria, on the other hand, need 0.3-micron pore size. For blocking viruses, it needs to be about 0.02 micron. Many backpacking water filters on our list come with a pore size between 0.1 to 0.2 micron. Hence, they can wipe out bacteria and protozoa.

3. Quality and durability

Always select the water filters that use premium quality materials. If you choose low-quality water filters, there are high chances that they might stop filtering water in the middle of your tour. To avoid that kind of situation it is better to buy a good enough water filter that is quite durable. The more durability, the more it will last longer.

4. Filtering Viruses

It is rare for water filters to remove viruses. Mostly, the water filters can remove several types of protozoa, bacteria, and even micro-particles but not viruses. If you want to explore some less known places, it is better to pick the water filters that remove viruses. No one knows what kind of things water sources those hidden places have.

5. Flow Rate

The flow rate reveals at what speed the water filtering system can filter the water. You can measure it in terms of liters per minute. The water filters with 1.75 liters per minute flow rate can clean 4 liters of water within a few minutes. You have to remember that the straw and squeeze water filters do not have any flow rate because it depends on your suction power. When you are traveling in groups, it is better to choose the water filters with a high flow rate so that every member can have water. Moreover, they will save plenty of time.

6. Weight

The backpacking water filters are available in various sizes, shapes, and weights. Some are as light as a ball, and a few are too heavy to carry. The weight and heaviness of the water filtering system depend on the type of water filter. For example, the water filtering tablets weigh less than one ounce, while the gravity water filters weigh more than 6 ounces. We recommend that you choose the water filters that weigh between two to five ounces.

7. Type of water filter

The backpacking water filters are available in various types like pump water filters, gravity water filters, straw water filters, individual water filters, and many more. You can select the water filter as your wish considering a few things like the flow rate, maintenance, and more.

8. Filter Maintenance

The main motive of water filters is to eliminate the impurities or contaminants from the water. Hence, it makes sense that they need proper maintenance or cleaning to work properly. It is necessary to clean the built-up particles to use the water filter. In general, you can clean the gravity and straw water filters by backflushing the air or water. For some types of water filters, you need a back syringe to maintain them. We suggest that you buy the water filters with less maintenance which saves both your effort and time.

9. Cost

Of course, the money you are ready to spend on the water filter is of absolute priority. When you are stuck with less budget, you pick among the affordable water filters, which are quite good. More usage of technologies and quality materials will always improve the total price of the water filter. Hence, consider and make a list of what features are necessary for your backpacking journey. It is better to avoid spending on the features that you are never going to use.

Bottom Line 

We tested hundreds of backpacking water filters which are small, compact, and are good enough to use for backpacking or hiking. We took many water filters into the backpacking field to test them in various conditions and water bodies ranging from dirty ponds to clean water streams. And the above six products stand the best throughout our testing. But our top pick is Platypus GravityWorks High-Capacity Water Filter System.
