Buying Guide for the Best Portable Water Purifier

Your next outdoor family trip can be made hassle-free and more enjoyable. Now that you have read about your options for the best portable water purifier, you just need to make some considerations before a final decision. These filters are easy to install and carry along, providing more space for other important stuff in your backpack. Here are a few factors to keep in mind for a long term outdoor water purification solution.


Each portable water filter comes with varying storage capacity from as low as 30 ounces up to 1 or 2 gallons of water. You need to calculate the amount of clean water you and your family will need in an outdoor location. Additionally, some of the filters need to be attached to a storage unit, depending upon their output rate.

Portable filter bottles do not need any extra storage unit, but they have a low output fitting an individual’s need. If you need water for a group of people, look for a filter that can filter two or more gallons of water in one go. The addition of a large gravity bag will be helpful in the storage of water.


Most of the portable filters come with two to three filtration stages to purify water. These filters are capable of filtering particles as small as 0.01 microns. The filtered water should be free from any bacteria, viruses, pathogens, or staph to ensure you have clean water. All of these microorganisms are responsible for various stomach and breathing diseases. So, look for a system that can completely remove them!

The third filtration process is the activated carbon filter that absorbs all the particulate impurities. It will also help in the removal of any odor or metallic taste from the water. It is scientifically proven that chemicals like lead and mercury are harmful to our health. Make sure your portable water purifier can remove such chemical impurities.

Flow Rate

You cannot spend hours and hours being thirsty while waiting for your supply of clean drinking water. Make sure you go for a portable purifier that has a high rate of flow. This will ensure that a large volume of water is filtered in one go. You can take along a portable water bottle or container to store a large amount of water after filtration.

Try to avoid filter bottles that have less suction and a lower flow rate. You can find portable purifiers that can filter up to a gallon of water in just ten minutes. Just find a large enough storage tank to keep the purified water.


While you are camping outside, you need to make sure the filter that you have brought along is sturdy enough to sustain outdoor use. Additionally, the medical-grade filter parts will ensure the cleanliness and hygiene of water. Look for a filter that has a BPA-free durable inner and outer construction. Along with non-toxic material, make sure the material will last you a long time with the least amount of tear.

You can choose from material like Polysulfone, a fiber membrane filter for inner material. The outer material should be scratch and wear-resistant like ABS shell material, which is as strong as a car bumper or Tritan. The material should not disintegrate in composition after a while and contaminate the water supply. Some carbon filters become powdery after a few months of use. Look for a high-quality carbon filter so that it does not need to be replaced too soon.


Any water filter requires some amount of cleaning and maintenance after purifying a few gallons of water. The filtering units of the purifiers entrap the physical impurities that are present in water. You will need to periodically clean the filter using suction cups or by the method of backwashing with clean water. Look for a filter that has easy maintaining steps.

The carbon filter also needs cleaning and replacement after a stipulated time. Make sure you have at least three to six months of constant use before you need to replace it. The maintenance is also dependent on the composition of water. So, find out about the water that you will be filtering and what kind of physical and chemical impurities it has.
