10 Reviews: Best Portable Water Filter Straw (Sep 2023)

With a 0.1-millimeter hollow fiber membrane, the Waterdrop water filter straw efficiently removes most of the hazardous chemicals from water. High-grade coconut shell-activated carbon fiber enhances odor and flavor, assures water safety, and provides a pleasant drinking experience. No need to worry about drinking from rivers or lakes or glaciers, as long as they’re clean. The detachable, double-sided cap may be used in a variety of ways. Many water filter functions may be accomplished with one Waterdrop water filter straw. Drinking water may be filtered by attaching a water bag to a water bottle. It’s important to have enough water on hand for all of your outdoor activities: hiking, camping, foreign travel, and disaster preparation (earthquakes and tornadoes).

Great water filters, also at a great price. If possible I will always buy Waterdrop Filter.

It has a hollow fiber membrane that is 0.1 microns thick, which can effectively remove harmful substances and bacteria from water. The use of high-grade coconut shell-activated carbon fiber improves odor and taste, makes water safe, and makes drinking water more enjoyable. Connects to water bags or water bottles so that you can drink clean water. The extra syringe doesn’t need to be used to backwash, so there is no need for it. It doesn’t have a lot of extra parts and takes up less space, so you get pure water with the most ease and comfort. All of your water needs could be met by the filter straw, which could be used for hiking, camping, and traveling. With a small frame but a lot of filtering power, the straw can provide up to 100,000 gallons of safe drinking water.

It has a high flow rate and barely weighs 2oz. Its straw construction is great for filtering water from streams, lakes, ponds, and other polluted sources, making it the best survival item for hiking, camping, ultralight backpacking, hunting, travel, scouting, and emergency preparation. A LifeStraw, an important component of any survivalist gear lineup, is missing from no catastrophe kit or bugout bag. Unlike many similar filters on the market today, LifeStraw has met EPA standards for water filtration in independent testing and removes a minimum of 99.9999 percent of waterborne bacteria, and exceeds EPA standards for water filters.

The quality of this is great. Really easy to use. The directions are clear and it’s compact enough for traveling.

Sawyer’s lightest and most versatile personal water filtration system is the Sawyer MINI Water Filter, which is small, lightweight, and high-performance. It’s great for camping with kids and traveling to places where tap and bottled water can’t be trusted. The Sawyer MINI water filter fits in the palm of your hand and weighs just 2 ounces, making it ideal for ultralight backpacking as well as emergency preparedness. This 16-ounce squeeze pouch is durable and folds up when it’s empty, so it won’t take up space in your bag.

This is the first small portable water filter I have used. So far so good. I have only filter tap water but I will try it when I go hiking. I would buy this again. It's super easy to use. I bought it because of Richie's review.

The LifeStraw Mission is a gravity-powered water purifier that uses an award-winning technology that doesn’t need chemicals, batteries, or moving parts to make water clean. 99% of bacteria, 99% of protozoa, and 99% of viruses can be removed by this straw. The Mission water purifier has a large capacity that can provide clean water for a lot of people. It’s great for camping, hunting, and other group or family activities, as well as disaster and emergency survival kits. If there are any lakes or ponds near where the reservoir is going to be built, they can fill it up and hang it from a tree or other strong thing.

We seriously LOVE this product. It did everything we were hoping on our 10 day Bowron Lakes trip and we drank from everything - cold mountain streams, small shallow lakes, deep cold lakes, silty rivers & even marshy areas. We were healthy and happy with the taste everyday. [...]

You may use this survival gear to swiftly and easily collect drinking water. An essential item for hiking, camping, and backpacking is a water filter straw. Only 2.65 ounces, 6.7 inches long, and 1.1 inches in diameter, this straw filter is the lightest on the market. For outdoor activities, this survival gear takes up little room and is simple to stow in your backpack, fits in your hand, or hangs around your neck. Simply plug the hiking water filter into a water source or connect it to a water bottle or hydration pack and you’re ready to go. To prolong the life of the straw, just blow out the straw after each usage.

It’s nice quality and really portable. I’ve tested water quality and it passed in removal of solids and harmful bacteria.

As a tiny, lightweight, and easy-to-use water filter for outdoor leisure that delivers good filtration and won’t break your wallet, this is the one for you! Additionally, the package includes a Sawyer squeeze bag that may be filled with water for future use. This pocket-sized water filter is easy to carry along, weighing just 2 ounces. Using it as a straw to sip straight from a source of freshwater is an option. An inline water filter that may be added to the 16-ounce squeeze bag is supplied. Drinking is now much more convenient as a result of this. Drinking on the move is also an option. To use, just place the filter on top of the refillable bag and screw it on. Alternatively, you may suck on the straw and sip from a bottle of water. When not in use, the pouch may be compactly stored in your travel bag thanks to its roll-up design.

Best portable filter you can get. This is by far the go-to of the backpacking, camping, bushcraft, hiking, survival communities. Better than Life Straw (which I have also used) because you can screw this into your standard bottles and backpack squeeze bags. And, it comes with an attachable straw, so you can use it like a Life Straw anyway.

Works great for a portable filter, there are a few styles out there, but if you're looking for compact, this fits the description

In the event of an emergency, the Etekcity camping water filter straw is an excellent choice. Using the filter extension, portable water storage, and prefiltration, you may safely consume up to 1,500 liters of water from practically any lake, river, spring, well, or even precipitation. 480ML of water may be stored in the Foldable Water Pouch. When camping, you may easily attach it to your backpack using a D-type hook. All heavy metal ions, including arsenic, lead, and mercury, are removed by the Etekcity Personal Water Filter.

This is a quality, high-tech portable water filter. It is competitive with much more expensive models. It uses replaceable pre-filters, carbon, then filter tubes to produce clean, good tasting water. [...]
