Buyer’s Guide

Before purchasing your best backpacking water filter, it is quite necessary to learn about the difference between water filtration and water purification. Also, it is essential to know about different types of backpacking water filters and purifiers to make your selection process easier. 

But from where you can find all this information? 

Therefore, to make things easier for you, we are here with a buyer’s guide to help you know about different water filters and purifiers. Also, you will be able to know about different factors that you should consider before purchasing a particular water filter. 

Difference between Water Filtration and Water Purification

We have added both the water filtration and purification units in the below list. Therefore, it is necessary to understand the difference between the two. 

There is no prominent difference between these two, and that’s why these terms confuse many people. But if we focus on a difference, then water filters have the ability to remove bacteria and protozoa whereas water purifiers filter viruses as well. 

Now, it is the time to discuss different types of water filters and purifiers.

Pump Water Filters and Purifiers

As we all know that water filters remove protozoa and bacteria from water and the water purifiers also treat viruses along with bacteria and protozoa. So, these pump filters and purifiers also work on the same principle. 

Pump water filters and purifiers are not new; they have been used in the past and still they are very effective. But after the introduction of gravity and bottle filters, these pump filters have slightly lost their value. 

They feature a hand pump through which water reaches the filter from one source and then filters out into another storage container. The one hose sucks the water with the help of hand pump and filters the water. On the other side, the second hose helps the filtered water to move into a clean water container for drinking or using.   

These pump water filters effectively remove the contaminants in no time but require elbow grease for smooth operation. But these filters require some regular maintenance. The cartridge used requires some regular cleaning to get the best output water. 

The best examples of pump water filters and purifiers are Katadyn Hiker Microfilter Water Filter and MSR Guardian Water Purifier. 

Gravity Filters

Gravity filters are best for treating a large amount of water. These filters are best for camping and hiking when you are with a group of people. 

These filters don’t use any pumping system to filter the water. Instead of this, the gravity shows its power to filter the water. 

Gravity Water Filter

If we take an example of the Platypus GravityWorks water filtration system, then it offers the fastest and easiest way of cleaning the dirty water. It can clean 4 liters of dirty water at a time in less than 2.5 minutes. 

These types of gravity filters are quite easy to use. All you need is to fill the dirty water into the dirty bag and hang it at some height. The water then flows downward through the hose into the filter and then collected into a clean reservoir for drinking. But keep in mind that you should hang the dirty water container up than the clean water reservoir to let the gravity works.   

But many hikers and campers don’t prefer these gravity filters as you have to carry a lot of stuff to filter the water in the backcountry. Also, it is not easy every time to get a place to hang the dirty water container. 

So, if carrying all the stuff like hoses, dirty bag, filtration unit, and the clean water reservoir is hard for you, then you can go for pump filters, straw filters, and even the chemical treatments are quite effective in making the water drinkable. 

Bottle Filters and Purifiers 

These bottle water filters are best for backpackers as they are versatile. You cannot only drink water straight from the bottle, but you can also store the filtered water into another container for future use. 

The single stage hollow fiber filter is used by the bottle filters. This filter is commonly used by the gravity, inline, and squeeze water filters. They are light in weight, and that’s why many hikers and cyclists prefer these bottle filters and purifiers. 

But their filtration rate is not great. You have to wait for a little time to get your filtered water out. In comparison, various pump filters filter the water at a higher rate. Other than this, you can’t say that gravity models require some efforts to filter the water when you have this bottle filter or purifier. 

Chemical Water Purifiers

Chemical water treatment is either done with the help of tablets or drops. Both these things are quite effective in purifying your water. Many people carry tablets or drops for a safer side to use them as a secondary option to filter and purify water. These chemical water purifiers take around 30 minutes to a couple of hours to purify water. 

The best chemical ingredient that many people prefer is the Chlorine dioxide. Take an example of Aquamira chlorine dioxide drops where you only need to add drops into the dirty water to make it pure. Also, the best thing about this chlorine dioxide is that it has no taste and no color. You can freely add chlorine dioxide into the water without worrying about the chemical taste or color. 

Other than chlorine dioxide, you can also use Potable Aqua Iodine tablet that is the most prevalent chemical water purification system. But one drawback of these tablets is that you have to drink the water with a chemical taste. 

Straw Filters     

Straw filters are also handy and common between hikers, mountain bike riders, and long-distance backpackers. The best thing about these straw filters is that you can directly suck the water from ponds, lakes, and water streams. There is no need to carry water with you or make some efforts like the other water filters and purifiers. Also, they are light in weight and less expensive as compared to the gravity and pump filters. But these straws are not for everyone as you can’t store water with the help of them. Also, it is risky to only depend on the straw filter when you are miles away from your home. 

Ultraviolet Water Purifiers

The last type of water filters and purifiers include the UV water purifiers. They use ultraviolet rays to remove viruses, bacteria, and protozoa. It is quite an effective way of treating water to make it safe for drinking. 

Since these water purifiers go directly into the non-filtered water, therefore, it is necessary to dip it into clear water. Also, these purifiers are not capable of eliminating the organic matter. Other than this, a UV water purifier needs batteries to continue working. Therefore, you must have to keep batteries with you when going outdoors. 

As, we have discussed all the types of water filters and purifiers, so it is the time to look into various factors that need your consideration before purchasing your ideal backpacking water filter according to your needs. 

Factors to consider before purchasing backpacking water filters

Filter Life

The life span of a cartridge that your filter uses is the most important thing to consider. Many people don’t focus on the filter life, thus spend more money on replacing the cartridges. So, it is crucial to consider this factor. 

But different types of water filters feature different cartridges having a different life span. Here we take an example of Sawyer Squeeze which can treat up to 1 million gallons of water without a need of replacing the cartridges. Also, the best thing about the Sawyer Squeeze is that the company hasn’t worked in making the replacement cartridges for it. See, how much trust they have on their product. 

But other than the Sawyer Squeeze some water filters have a life span of 15000 liters of water whereas some filter cartridges need replacement just before reaching 1000 liters. 

Here, it is important to note that some water filters and purifiers are less expensive and their cartridges also come with a shorter life span. So, these filters will make you pay more in the long run as compared to those filters that are expensive but have great cartridge life span. Therefore, it is necessary to go for the right filter by keeping this thing in mind.     

Weight of the product

Backpackers always prefer compact and lightweight water filters and purification units so that they can easily fit inside their bags without making the bags heavier. There are many filtration units that are light in weight, but there are also some effective systems that are bulky and heavier. So, it depends on you how much weight of a filter you can easily afford in your bag. 

If we talk about the lightest option, then it is the chemical water purifiers that come in both the droplets and tablets. These drops or tablets weigh nothing; also they will take very less space in the pockets of your bags. Aquamira chlorine dioxide droplets only weigh 3 ounces whereas Potable Aqua Iodine tablets then they come weighing 6 ounces in case of the neutralizer tablets. Also, if we talk about filters, then Sawyer Squeeze water filter is only of 3.2 ounces. Also, Katadyn BeFree Water Filter, LifeStraw Water filter, and SteriPen Ultra are of 2.3, 2, and 4.8 ounces respectively.      

Pump and gravity filters carry more weight than the other types of filters and purifiers. Also, they take more space in the bags. If you are traveling with a group of people and you have multiple bags along with you, then you can go for these filter types. Platypus GravityWorks filter and the MSR Guardian are the perfect examples of heavy filter systems. 

But there are some filters that are neither heavier nor lightest. 

Flow Rate

Before purchasing a particular model or type of water filter, the flow rate is also important to consider. The flow rate of the filter always matters no matter whether you are purchasing a unit that works at homes or looking for a backpacking water filter. 

Different filter models offer different flow rates. Some produce good amount of filtered water in less time whereas some are not efficient enough to produce an adequate amount of water in a minute. 

MS Guardian filter and purifier top the list as it can deliver 2.5 liters of water in a minute. Other than this, gravity filter like Platypus GravityWorks can fill a clean container up to 1.75 liters in one minute. There are also different filters that offer a slower flow rate than others. But it is better to go for a filter system that can filter out water in a large amount and in less time. 

Also, if we talk about the chemical treatments, then there are different chemicals that can purify water between 15 and 30 minutes. 

But here one thing you should keep in mind is that most of the times, the flow rate fails to match the listed number by the manufacturers. So, it is necessary to make sure that whether your chosen product can offer you the same flow rate as its written. 

Pore Size

Pore size is measured in micron that refers to how effective your filter cartridge is to block the particles present in the flowing or still water. Different filters and purifiers come with different pore sizes, so it is always better to go for a filter that features smaller and tiny openings. Protozoa and bacteria can be easily blocked with the help of 0.1 or 0.2-micron pore size. But to prevent viruses, you must have a unit that can both filter and purify water such as the MSR Guardian.
