Because of it, this product has one of the fastest flow rates. Another thing that makes it a great choice is its capacity. It is rated to 100,000 gallons. And for its price, the box includes a 16-ounce reusable squeeze pouch, 7-inch drinking straw, and a cleaning plunger.

3. Etekcity Portable Water Filter Filtration Straw Purifier Survival Gear

Even more, the filter will remove rust, silt, worms, and other large contaminants. Additionally, chlorine, heavy metal ions, THMs and VOCs will all be out of your water.

A high-performance glass fiber filter, a ceramic pre-filter that can be tailored individually according to the cloudiness of the water, and active charcoal for eliminating odor.

The filter does a fair job and can be used with water of all kinds. For instance, rivers, lakes, ponds, creeks, mud puddles, and third world tap water. Most contaminants will be removed. The straw has a 0.1-micron purifier and can eliminate up to 99.999% of bacteria and parasites. The straw can connect to any 28mm water bottle. The lifespan of the filter is about 400 gallons.

The Importance Of Portable Water Filters!

So here you are in an outdoor situation trying to drink some fresh, healthy water. You won’t have any other choice but to go for this filthy, contaminated puddle unless you carry a portable water filter around. It can come in a number of shapes and forms but the upsides are common to all. You simply have to become familiar with the best reasons to buy a portable water filter.

The Most Distinguished Benefits Of Using A Backpack Water Purifier

  • BACKPACKING WATER PURIFIERIt can be a lifesaver – any portable water filter used during camping might come in handy in the direst of situations. However, this isn’t true only for people who are into survival. No sir, any family having an outing can benefit from a small water filter in their bag. The fact that such a device removes so many contaminants from dirty water is vital. Whenever you need a sip of water, you just reach for your carry-around filter and you are good to go. People out there in the wild truly see this as a magical invention

 

  • Instant filtration – no matter which type of portable water filter you choose, you will always have fresh water instantly. These filters are composed in such a way that as water passes through the media, it instantly comes cleansed on the other end. There is, of course, at least some sort of delay and reduction in the water flow but this is all negligible.

 

  • The price isn’t huge – while there are certain products which might hit the 3-digit price tag, most filters in this class are fairly cheap. Since such a device is crucial to any survival kit, you can’t expect the price to be very high. In fact, if you go through any list of the most important items to a survival kit, you will notice that most things are inexpensive.

 

  • Small in size – one of the biggest advantages of portable drinking water filters is their size. They are designed to be easy to carry and to be tucked away without any effort. Yes, this is not weaponry we are talking about but concealed carry is exceptionally easy when we talk about portable water filtration. Most products fit in little backpack compartments or in small pouches. Some people even have them in their pocket although we do not recommend that. Even the bulkier filters with tubes and containers can be folded in such a way that will make your life in the wild pretty easy.

 

  • Easily replaceable – You don’t have any big installation to think about here. There’s no huge set of components that require building in or sealing to a wall. Even simpler domestic filtration systems regardless of type require some sort of installation or maintenance. You don’t have that here. Everything is used on the go and when its life expires, you simply replace it. After all, we already clarified that the price of a portable water filter is close to the one of a **replacement filter for a decent water filter pitcher**.

 

  • Relatively long life – even though you will have to toss it when it dies, the portable water filter will give you plenty of clean water. The average lifespan of one of these units is about 200-300 gallons of water. A single person should be able to last almost one whole year if they drink water in the wilderness every single day. After all, the daily dose is about 1 gallon of water per person. Now if you go camping with your family, you will either need to get more filters at the same time or simply replace your existing one more often than expected.

And Let’s Not Forget That There Are Also Downsides

This is not to discourage you from buying a pocket water filter. In fact, many people prefer spending extra money in order to get some portable purification systems used by the military. As we all know, this is a sign of quality. In any case, there are still drawbacks and here are some of them:

  • Not effective against many contaminants – in all fairness, portable water filters typically specialize in removing only certain threats from filthy water. There’s hardly a product out there which will take care of sediment, heavy metals, and viruses at the same time. Such properties are typical for way more complex and advanced devices such as the finest reverse osmosis water systems.
  • It’s not great if you venture with others – little filters are more or less designated for a single person use. Even though hygiene is not a top priority during an outing, we still cannot neglect the fact that it is not recommended for people to drink from the same mouthpiece.
  • You almost always need a spare one – it is hard to keep track of how much life the filter has left. During the first days after a purchase, you won’t have such worries but what happens when you’ve been using your little filtration buddy for 8 months? It can stop being effective any second and you might be stuck without any water to drink out there. Carrying 2 portable water filters for travel is perhaps the smartest thing to do in this case.
  • Hard to clean – yes, filters are not designed to be cleaned although some users will advise you to go for it. In this case, you can only hope to blow some dirt back through the filter with your mouth. That’s all you can do in order to prevent any buildup and prolong the life of the media.

Features To Look For

There’s no secret that people want to be conscious with their finances and when you upgrade your survival kit you always want to be mindful. It would be awful if you bought a product that doesn’t meet your needs and this is why we want to open your eyes. Here we will mention all the more important specs and characteristics that you might want from your portable water filter.

Size

portable water filter reviewsIsn’t that the most important characteristic of these things? While some might argue that effectiveness matter more, we can tell you that if you can’t carry the filter with you it doesn’t matter how good it is. In that sense, check the proportions and the flexibility of your filter.

For instance, straw filters are typically foldable and they are as big as a small pipe. These products are easy to tuck away and can be whipped out at any given time. Some bottle filters are very inconvenient to carry in a small bag because they are essentially…bottles. On the other hand, there are those bottle filters which combine a straw filter and a bag. They are easily folded and you can carry them around seamlessly.

The size of the pump filters is not the biggest problem as much as all the parts that you have to also have. These filters come with a hose and a tube, the body of the unit is bulkier because water is stored there. So in case, your bag is tight, you might want to look for other portable water filters for camping.

Weight

This is the other spec related to the physical characteristics of portable filters. Weight is somewhat linked to size but not necessarily. Even if a unit is light, it might still require a little bit more space. Your best bet here again are the straw filters and the bottle filters that come with a clean bag.

Convenience

Who says that convenience doesn’t matter in a survival situation? Of course, it does, because you want to go through your routine quickly. This means that you have to be able to quickly whip out your portable water filter and use it.

In that sense, the ones that have a number of parts needing to be assembled will require more time. In some situations, this can be quite the hassle especially when you have to act quickly. Filters with hoses and screws are harder to unfold and they also have plenty of parts that you might end up losing.

This goes to show us that most portable filtration systems for any type of disaster relief are best if they are constructed simply.

Speed and Capacity

Performance matters and in the case of carry-around water filters, speed has to be impeccable. Other systems such as household reverse osmosis filters will take a lot of time to produce moderate amounts of water. In our case here, though, we want something that handles relatively little volumes of filthy water and converts it to a drinkable one instantly.

This is why opting for a straw portable filter is among the top choices. It is true that some little filters work faster than others so make sure to check the specs before you make your purchase. Of course, for family camping, you might not need a very quick filter.

Capacity is the other aspect as it will determine the filter’s life. It goes without saying that the longer you can use a certain product the better. But you want to see the ratio between long life and effectiveness. This means that if your filter barely filters out any filth from your water the long lifespan won’t do you any good.

Price

The initial price of the unit is not the only argument for or against buying it. At the end of the day, you might end up overpaying for a certain filter but it might be incredibly useful to you. In that sense, the price is justified.

Furthermore, you want to check the eventual expenses for replacement filters as well. Calculate the total amount you will spend on maintaining your portable filter over 2 years for example. If you don’t like the number, then look for other options.

 

The Most Popular Types Of Portable Filters

While all portable water filters essentially do the same thing, there are some key differences between the various types. You need to be familiar with them in order to make the right choice. Here are some highlighted properties of these filters.

Pump Filters

Size is not optimal here. Pump filters are among the more complex purification products for your outing. You basically have a hose and a tank for clean water. Once you connect the whole thing together, that’s when you can start obtaining fresh water.

On the downside, you will need to vigorously pump the water from the puddle or the stream in hopes to fill a relatively small tank. The filtration method may vary as these products are large enough to accommodate filters with different properties.

For instance, you might have an activated carbon filter in there, a ceramic one or even a fiber filter. This is an advantage because it allows you to select the most appropriate filter for the water you want to cleanse.

Straw Filters

best portable water filterThese are the ultimate and most popular portable water filters out there. They are basically plastic pipes which you either dip in the filthy water source itself or in some sort of a jug. Whatever the case, the filtration happens right away and that’s the biggest advantage.

You cannot expect a very thorough cleansing of your water, though. While there will be an improvement in taste and odor, some particles might still make it through. These filters are also easy to clog. Some buildup will occur over time but that’s to be expected. The life of straw filters might be shorter than the others’.

Gravity Filters

The mechanism here is a rather simple one. The product features a container and then the filter is situated below it. Thanks to the gravity, the water passes down through the filter. Some quick drawbacks to mention here are the slow speed of filtration and the likely contamination of your fresh water.

The latter occurs when the filter is not sealed tightly and the water bypasses the filter. There are also a number of parts to be assembled here and that’s sometimes a turnoff to many people.

Bottle Filters

These are like small water filter pitchers. You essentially have a bottle which has a filter right at the neck. The functionality here is good because these filters will rid you of both heavy metals and viruses.

A slight knock on bottle filters is the fact that they are bulkier and often require more space in your backpack. Be careful not to break your bottle because the filter will be useless. Some bottle filters are also made of foldable plastic rendering them unbreakable.
