2. Royal Berkey Gravity-Fed Water Filter

It measures 23 inches tall and 9 inches in diameter which is enough space for water for 2-4 people a day. The powerful purification system purifies and filters water by removing over 99% of viruses, pathogenic bacteria, protozoa, and trihalomethanes. It doesn’t stop there as it also removes inorganic minerals, heavy metals, and even pharmaceutical drugs although, you may not find those out in the woods as bears and squirrel usually stay clean.

Each filter works for 6,000 gallons of water before you need to change. This equals out to about 2 cents cost per gallon. Hello, affordable health! As the system does not require electricity, tools, or plumbing to operate. The system requires cleaning which can frustrate out on a campsite and annoying based on the high price.

3. Membrane Solutions Straw Water Filter Survival Filtration Portable

As water tastes so different based on location means it’s a very personal preference and not everyone will agree on flavor.

6. Survivor Filter PRO X Electric Water Filter

While the other portable water filtration systems on the list do not use any electricity, this one does and it may be exactly what you are looking for. The Survivor Filter Pro X comes with a mid-range price making this an excellent option for people on tighter budgets who want to get out in nature and enjoy clean water.

Because the filter uses electricity, this means no pumping, pressing, sucking, or any other action is needed except to press a button. Yep, that’s it you press a button with the hose in the water and the other side connected to a water bag and wait. You even get a few options for power. Connect to a traditional outlet, a power bank, a solar panel, or use AA batteries if you run out of power. It also provides 17 ounces of water per minute for fast, healthy water.

The portable device is small enough to fit into any space you need except maybe your pants pocket. It comes with a convenient back-washing syringe for easy cleaning even in the wild.

Each filter has three filtration stages to clean up water. Stage 1 includes a pre-filter, carbon filter, and an internal ultrafilter to clear away the rest of the contaminants in water. The filter cleans out bacteria and staph, protozoa, parasites, and viruses as well as reducing heavy metals for clean water. The only issue with this filter is it may not be the best option for those without access to power for extended periods of time, but it’s great for shorter camping trips!

7. Sawyer Products PointOne Squeeze Water Filter System

With the Sawyer Water Filter System we head back into manual labor territory, but don’t worry you just have to squeeze a little to get your clean water. This model is lightweight and extremely portable with a 0.1 absolute micron hollow fiber membrane inner water filter. This filter comes with several filter options including pouches and a faucet adapter but we are specifically looking at the three personal pouches.

The company claims the highest level of filtration on the market as it removes over 99% of bacteria, and protozoa, and 100% of micro-plastics. It comes with a built-in and removable push/pull cap to spray water into your mouth or bottle from the pouch. You can also attach it to a standard threaded water bottle.

When not in use, you can roll up the pouches to fit in any space you need such as a backpack or storage container.

Finally, you can clean this bottle and reuse it almost indefinitely without ever having to buy or replace another filter. When the water flow begins to reduce, clean it out by back-washing to restore the filter flow rate. Beyond a few customers receiving defective units, most customers love this filtration system.

8. BOTTLED JOY Water Filter

The Bottled Joy Water Filter is another portable straw-like device with two stages of filtration. No matter where you go, this filter will serve up safe, drinkable water whether from a lake, stream, or river. It’s a great addition to your backpack for camping, hiking, or even for emergency preparedness. Though, do not use this in the ocean as the salt can destroy the filter.

Also, doe not use this on chemically polluted water as this can damage the filter too. Otherwise, you have a premium filter for water. Stage one uses advanced fiber membranes to collect and remove micro-plastics down to 0.1 microns and reduces turbidity too. The second stage uses the standard activated carbon filter to reduce odor, chlorine, and bad tastes.

You need to use the included syringe to draw up the first 17 ounces to active the straw. Pair the straw with a bottle for added functionality. One filter will last for 400, 17 ounce (or 3 months before you need to replace the filter depending on use) uses to keep you hydrated without the need to carry around expensive water bottles.

Customers love this easy-to-use filtration system. The economical product comes in at the lowest price but does not filter out as much bacteria or viral contaminants as the other brands. This is maybe an entry-level filtration system mainly for cloudy or odor-filled water. Consider a more advanced option for extreme water conditions.

9. CrazyCap Deep UV Light Water Filter Cap

One of the neatest technologies around is the Crazy Cap Water Filter. Not only is this portable but also extremely useful for camping and hiking as it can clean any smaller surface using UV light technology. Bacteria, viruses, and microbial’s disappear with the click of a button.

Tap the button on the cap twice to activate the normal mode to clean your water in one minute. For extra dirty water, tap the button on the top five times and to activate crazy mode and completely eliminate all microbes in two minutes. This cap can also sanitize other items like headphones or phones. It has a 7-day battery life on one charge and goes with you where ever you go. It’s not the best option for camping trips longer than seven days unless you bring an additional power supply to charge the cap.

Next, the bottle fits more cola top styled insulated bottles by major brands to clean those too. You can only use this cap on stainless steel bottles as you do not want to degrade plastic. This means you can use an insulated bottle for cold water! Do not use this filter though if you wish to reduce sediments as it works specifically for killing viral and bacterial issues.

This bottle cap can save you thousands of dollars as it can handle half a million treatments in its lifetime. Includes a charger, an extra gasket, wipes, and a manual. As it’s a UV light, it cleans itself too for added value. Mind you, this cap does not include the bottle but you can probably use bottles you already own.

10. LifeStraw Personal Water Filter

The last set of filters are the economical LifeStraw set of three filters. This is the brand most people think of when they think portable water straw and for good reason, the brand has a great track record. The three-pack works for multiple people on the go while hiking, camping, or just to keep in case of an emergency drinking needs from dirty water locations.

Each Life Straw filters up to 1,000 gallons of water for long life before they need to toss out the straw for a new one. These straws also remove over 99% of bacteria including e-coli, campylobacter, vibrio cholera, pseudomonas aeruginosa, shigella, and salmonella. You can also expect 99.9% removal of protozoa, giardia lamblia (or beaver fever, cryptosporidium parvum, and entamoeba histolytic.

Dirty water enters the bottom of the straw and goes through a hollow fiber membrane to trap pathogens and get them out of your water safely. The straw ways only 2 ounces making it lightweight and easy to pack anywhere you need. You can even pack all three in case you lose one or break one and the affordable price makes this possible.

Now for the minor issues. Do not use this for chemical toxins, seawater, or urine as these filters will not remove contaminants from these sources. Also, the straw is breakable, so pack with care and use a soft case for this with foam if possible or if it will be packed in with heavy items. Finally, sucking on any filtered straw takes extra work to get the water out of the filter.

How much water should I drink while out hiking or camping?

You need roughly two cups of water per hour for each adult when out camping or hiking. One of the fastest ways to get sick when out in the woods is by dehydration. If you only bring one necessity when hiking it should be water as humans can only live three days without water.
