Why do you need a portable water filter?

According to WebMD, a 150-pound person needs 75 to 150 ounces of water per day. This requirement can increase if you are living in a hot climate or physically demanding activity such as backpacking and hiking. If you are a hiker or a backpacker, an outdoor enthusiast or love going on camping, you would want to carry your own drinking water. 150 ounces roughly translates to 1.17 gallons which are equal to 3.785 liters. One liter of water weighs close to one kilogram, so 150 ounces is equal to 4.43 liters and will weigh 4.43 kilograms (about 9 pounds). That is a sizeable weight for one person to carry, and if you are the mule in the group or you are out for more than a couple of days, you may have to carry much more than that. That is precisely why most of us do not prefer to carry enough water.

Mostly, while camping you can come across water sources in the form of rivers, lakes, ponds or you can find water collected in shallow beds. The problem with these sources of water is that they cannot be considered safe for direct consumption. You can run the risk of water contamination. Many disease-causing organisms-bacteria, protozoa and sometimes viruses can contaminate these water sources.

Boiling water is one of the most foolproof ways to make water safe for drinking. But boiling water is a time-consuming process and you cannot set up a stove anywhere and start boiling your water. Moreover, after boiling, you will have to wait for the water to cool before you can consume it or transfer it to your carry bottle.
Due to these reasons, a portable water purification system is a must carry if you are serious about your health and well-being. If you have water sources available around the trail or near your campground, carrying a portable water purification system is much easier than carrying all that load of water you will need.

Water Filters vs. water Purifiers

Before we look at the factors to consider while picking the best water filters, let us look at how water filters differ from water purifiers.
Water filters are primarily meant to remove dissolved impurities, bacteria such as E.coli and Salmonella and protozoa such as Cryptosporidium. They do this by passing the water through microscopic pores with a size of as little as 0.2 microns. Water filters do not provide protection against viruses such as rotavirus and Hepatitis A virus. Bacteria and protozoa are the most common pathogens that you would find in water in the US and Canada. So a water filter is sufficient to carry in these regions.
Water purifiers go one step further by providing protection against viruses as well. They do it by using UV or similar mechanisms that eliminate these viruses. Water purifiers are also generally costlier when compared to filters. If you intend to travel around the world, you should consider getting a water purifier instead of just a water filter.
So as discussed above, unless you are globetrotting, a water filter should be your choice while exploring the outdoors in the US or Canada.

How to pick the best portable water filter?

When picking a portable water filter system, we need to look at the following criteria to arrive at a decision,

  • Type of the water filter system
  • Ease of use
  • Filtering capacity
  • Time to filter
  • Portability
  • Maintenance

Portable water filters are of three different types,

  • Pump filters
  • Gravity filters
  • Filter straws

Apart from this, there are two other water purifying water systems

  • Chemical based water purifiers
  • electronic water purifiers

What are pump based water filters?

Pump based water filters are the most common type of filters that are used for water filtering. These filters operate by pumping water through a filter which has a very small pore size, small enough to not allow bacteria and protozoa to move through it.

These filters can allow you to pump and filter an endless amount of water. Pump filters are a good choice when you want to have clean water for multiple days for a single person or a group. The filter used in pump filters is a generic ceramic piece infused with carbon or silver.

Cleaning these filter is very easy, it can be scrubbed clean to remove any blockage or can be boiled and dried to clear them. These filters have pore sizes of 0.2 microns which is more than enough to filter most bacteria and protozoa.

What are the advantages and disadvantages of portable pump water filters?

Pros
  • Can filter water very quickly, averaging 1 litre per minute
  • Easy to clean, most filters just require removing the filter and scrubbing them. On some of these, the hose can be rerouted so that the filter can be back-flushed
  • Can filter a large amount of water before the filter needs to be changed. Most of the units can filter anywhere between 500 to 50000 litres
Cons
  • Costly than the other options
  • Heavier and bulkier compared to other options

What are Gravity water filters?

These type of filters use gravity to push water through a filter from one bag to another resulting in filtered water, ready for consumption. This mechanism eliminates the need for a pump to filter the water. They are fast, easy and effortless. Their filter mechanism is similar to a pump but without the manual pumping. You hang one bag on an elevated platform like a tree branch or hold it high while gravity pushes water through a filter into another bag used for collecting the filtered water. You can also collect the water into a drinking bottle. Generally, a glass or hollow fiber filter is used.

Gravity filters are compact and are lighter than a pump filter. Generally, their filters do not last that long, but using the clearest water possible helps increase their longevity.

What are the advantages and disadvantages of portable gravity water filters?

Pros
  • Can filter water relatively fast, averaging half to one litre per minute
  • Not as heavy compared to pump filters and are easier to carry
  • Easy to clean, just reversing the water flow can clear the filter

What are Water filter straws?

Straw filters are compact, inexpensive and simple to use personal water filters that have become popular among outdoor lovers in the past decade.

As the name suggests, such filters consist of a cylindrical plastic or steel tube, which is about 1 inch in diameter. One end of the straw is put in the water and the other end can be used to suck water through the mouthpiece. And if you do not want to suck the water directly, you can fill up the water bottle or bladder with filtered water.

Such filters generally have two (activated carbon filter, followed by a hollow membrane) or three stages (additional pre-filter) of filtration and can last anywhere between 1000 to 1500 liters for Lifestraw and Etekcity to 350,000 liters for Sawyer filters. The filters are not replaceable, so once the flow from the straw stops, you would have to discard it and get a new one.
