Selecting the Best Backpacking Water Filter

When choosing a water treatment method for turning not-so-good water into potable water, there are a number of things to consider. After all, not every filter or purifier is the same and they can have some pretty significant differences. The first thing that needs to be realized is that there is a difference between filters and purifiers. Filters are designed to strain out bacteria and protozoa but only actual purifiers will kill the pathogens in the water and render them harmless. This is usually done using UV light or through a chemical agent.

The filter vs. purifier debate is not the only thing to consider when choosing a backpack water treatment method, however. Whether the filter has a pre-filter is something else that needs to be considered, as well as the type of water treatment method a filter uses. Some of them are easier to use than others and some of them are more expensive than other ones. Below are some of the features you will need to consider before purchasing one of these filters.

Is a Prefilter Necessary?

Some systems come with a prefilter and some don’t, which makes some people wonder if they are even a necessary component to filter water. While water can be filtered without the need of a prefilter, the prefilter does a number of things which make it a useful feature to find on any filtration system. It removes larger particles so the filter doesn’t have to deal with it. Some of the benefits of a prefilter include:

  • It allows the filter to filter water faster
  • It improves the ability of chemical treatments to do their job
  • It’s necessary before using a UV purifier

How Much Does it Weigh?

Another thing to factor into your decision to buy a particular filter is to consider how much it weighs. Hikers traveling for long periods will most likely want to get a model that’s as small as possible.

What is the Filter Made Of?

What the filter is made out of will determine how well it eliminates certain particles and how durable the filter is while it’s being used. Some of the more common filter mediums include the following:

  • Silica Depth Filter-This filter uses sands of different grain sizes to filter particles of different sizes as the water passes through it.
  • Fiberglass-This filter is effective at removing particles but is a bit more fragile than other types of filters.
  • Ceramic-Ceramic filters are reusable but they often become clogged quite easily.
  • Hollow Fiber-This type of filter strains out pathogens using micro-tubes and is quite durable.

What is the Micron Size?

Micron size is a term that’s batted around by a number of different filters without much information being given to the consumer about what it is or why it’s important. Generally speaking, the smallest virus is around. 2 microns, so any filter with that micron size will be able to filter out viruses. Some of the newer filtration systems have a .1 micron filter size but these often tend to filter water slowly.

How much Water Does it Treat Per Minute?

Something that can vary wildly among the different filter types is the number of liters or ounces a filter can treat per minute. Some of the top filters available can treat up to 2-liters of water per minute but other models may filter a whole lot less. How much water it actually can treat per minute needs to be weighed against other factors.

How Much Water Can it Filter During Its Lifetime?

The last and most important consideration that needs to be considered is just how much use the user will get out of a particular filter. Some of the top models out there can filter 1,500 liters of water or more before they need to be replaced. Other models, however, come in stages that can be replaced as they are depleted. This extends the use of the filter and essentially allows it to be used forever – or as long as the parts can be acquired and fitted on the unit.
