The best water purifiers are reliable, easy to use, and lightweight. It enables users to quickly remove pathogens from drinking water sources and fully believe that the water is clean. From backpacking to emergencies, you will find a water purifier system that meets your needs in our top products.

Even the most pristine waters can breed diseases. Animal and human excreta carry diseases and pathogens, such as protozoa, bacteria, and even viruses. With so many water treatment options on the market, it is difficult to know what to choose. Before investing yourself, understand what makes the best water purifiers and some of the top filters on the market. Using these products can help you protect yourself from disease and discomfort in the wild.

Convenience, reliability and cost make Sawyer Squeeze the best backpack water filter overall. It is very suitable for filtering water from various wilderness sources during the journey.

The Sawyer Squeeze water filtration system is the best backpack-style water filter of my choice. It provides a lightweight system that can quickly remove bacteria, protozoa, cysts and sediments as small as 0.1 microns. It comes with two foldable bags for collecting water, a 5 x 2 inch filter, a mesh bag and a syringe for cleaning the filter. It also includes the pipes and adapters needed to make it work as a gravity filter. The system weighs only 3 ounces and almost disappears in the crowded packaging.

Using it is easy and foolproof, which is one of the reasons why I rank it so high. Just fill the water bag, screw on the filter, and squeeze. The pressure created by the squeeze forces the water through the filter and fills a liter water bottle in about 30 seconds. If needed, you can scrap the pouch and use the water bottle (the filter is screwed into many disposable water bottles). Maintenance is easy. If/when the filter becomes clogged, simply push the clean water back using the supplied syringe. The recommended cleaning method includes rinsing with a water/bleach mixture.

Overall, this is a good choice for two weeks spent in the woods or as an emergency water supply system. But it should be noted that although filters like this can prevent the growth of bacteria, they cannot eliminate viruses. In areas with a lot of water for pathogens, use this filter in combination with chemical treatment and/or boiling.

Convenience, reliability and effectiveness make Katadyn's Steripen ultra-ultraviolet water purifier my best water purifier system of choice. The generated ultraviolet light killed the smallest pathogen in the unit I evaluated.

The Katadyn Steripen Ultra Ultraviolet Water Purifier is the best water purifier system I have chosen. The UV-C light produced by Steripen destroys the ability of bacteria to make you sick and makes the water safe and fast to drink with little fuss. The package comes with Steripen, a rechargeable lithium-ion battery and a USB charging cable-everything you need to start cleaning up viruses and other pathogens. The whole thing weighs 4.94 ounces, which makes it quite lightweight. Discarding the power cord when entering the site will reduce some weight.

This is the easiest system to use. Just remove the cap, press the button, and insert Steripen into a bottle of water. Stir the water gently to make sure that the light touches the entire contents of the container, and remove the pen when the light is off. That's it. Cleaning is also very simple, just wipe it with a clean dry cloth.

Battery life is one of the few issues with this product. Steripen can kill 99.99% of protozoa (including Giardia and Cryptosporidium), bacteria, and even viruses, but only if the battery is charged. Lithium-ion batteries can usually purify up to 50 liters of water, so it should be used for most typical backpacking trips. It can be charged by any USB power source, including solar panels, battery packs, laptop computers or car chargers. Another potential problem is the transparency of water. If light cannot reach aquatic organisms, it cannot kill them, so your water source cannot be turbid. If you often encounter clear streams, then you are ready. If not, you may need to filter the water a bit to remove the sediment. Use Katadyn's FitsAll or other pre-filters to remove particles during bottling to ensure that UV rays can sterilize them. In addition, you may not want to drink coarse sand water anyway.

Affordability and reliability make drinking water iodine tablets the best water purifier for my survival. They are simple to use and are an excellent backup system in emergency situations.

Potable Aqua's iodine tablets are the first choice for the best water purifier for survival. This chemical treatment is 50 tablets in a 3 ounce bottle, which can treat a little more than 6 gallons of water. Its economy and small size make it a perfect emergency or backup purification system. Hiding a few bottles with your emergency equipment can provide you with plenty of safe drinking water when the chips are down.

The treatment is very simple. Put two tablets into a quart-sized water bottle and wait 35 minutes. Iodine kills bacteria, viruses and Giardia when it dissolves. You can easily dispose of more water by adding an appropriate number of tablets. Because the bottle is so small, you can fit your best backpack or backpack without lowering its weight.

Almost everything has shortcomings, and these water purification tablets are no exception. In an emergency, the waiting time for drinking water can be as long as 35 minutes. Pills change the taste of drinking water and sometimes change color. If your sense of taste is particularly sensitive, you can pick up the taste neutralizing tablets sold by Potable Aqua to restore the natural taste, smell and color.

Potable Aqua's iodine tablets are used by military and emergency aid organizations around the world because they are cheap and convenient to purify water. Even if you already have a major water filtration or purification system, a bottle or two of this water is cheap insurance in remote areas or in emergency situations. 

My experience in water filtration and purification comes from many years in remote areas, where I walked and paddled hundreds of miles in a leisurely way and as a guide. The leadership team used the remote areas and waterways of Maine and New Hampshire as the wilderness coach of the Appalachian Mountains Club to illustrate the importance of having a powerful water filtration system. I had to purify drinking water from all imaginable sources to ensure that myself and my participants have a safe and enjoyable field experience. When looking for the best water filter, I used the following criteria to evaluate the product:

When buying the best water purifiers and filters, there are many factors to consider, including the source of water you draw and the pathogens you need to guard against. Please consider the following before buying:

When choosing a filter or purifier, the amount of water you need is a key consideration. Do you need one in case your packaged water runs out, or do you want to filter for multiple days? Gravity and squeezable filtration systems are the favorites of many people who spend days in remote areas without access to clean drinking water; however, these systems are often bulky and require packaging and cleaning many components. For those seeking emergency water treatment, a small, packable straw or emergency chemical treatment may be the best choice.

The prices of water purifiers and filtration systems vary depending on the model you choose. The cheapest option is usually chemical treatment. These also tend to be the smallest, which is why it is often taken on travel as an emergency and/or backup purification system. UV purifiers are usually the most expensive, but they are small and convenient. Water filtration systems—including straws, pumps, gravity, and squeezing—are in the mid-priced category.

Another consideration is the type of water source you will encounter and the speed at which the water is purified. The squeeze and straw system can easily fill turbulent mountain streams and rivers, and it can be filtered into your mouth or water bottle almost immediately. The pump and gravity filtration system are very suitable for still water and large groups/large capacity needs. Finally, the UV system is very convenient because it can be decontaminated almost immediately and has a packageable size.

No water purifier is 100% effective against pathogens and diseases, but most water purifiers do an excellent job of eliminating the most common water threats in the wild. Water filtration can remove particles and most bacteria and protozoa, while water purifiers such as ultraviolet and chemical treatment can also treat viruses. If your water source is heavily contaminated, consider using multiple product combinations to make it most effective.

will not. Generally speaking, a water filter can protect you from protozoa and bacteria, but it cannot filter out tiny viruses. Water purification systems, such as ultraviolet light and chemical treatment, can also kill viruses.

Filtration systems (such as Sawyer Squeeze) are sufficient in remote areas of the United States and Canada, where the main concern is the spread of microorganisms through animal feces in the water. Viruses are more commonly spread through human feces, so if you are taking water from areas with heavy traffic, choose a purification system like Katadyn Steripen.

Yes! To purify your water, boil the water for three minutes. This effectively kills all pathogens. The challenge may be that it requires the use of stoves and the use of fuel.

The most suitable water purifier for outdoor activities will vary according to your needs and the water sources you may encounter. In view of the various situations I have encountered, Sawyer Squeeze is my best backpack and camping water filter choice. It is affordable, reliable, easy to use, and provides you with delicious filtered water.
