Importance of Water Filtration While On-The-Go

The importance of having access to safe, tasty drinking is something that cannot be understated. People need clean water to bathe, clean, drink, and cook with. The lack of clean water can lead to serious health issues and in some cases, death. Currently, over 840 million people lack access to clean water around the world. Here are some additional reasons why a handy water filter straw will benefit someone:

Taste – Obviously you want your water safe to drink, but the quality of water can taste different from one water source to the next. Using a water filter straw to filter your water means a crisp, clean tasting water that has less contaminants overall.

Peace of Mind – You can’t ever be sure what contaminants are in a water source, especially if you’re hiking, doing something outdoors, or just in an unfamiliar area. A water filter straw is easy to use, and, in most cases, you can drink straight from the water source. The filter cleans the water and what gets to you is safe, refreshing water.

Safety – At the very least contaminated water makes you sick and at the most it could kill you. Even if you think the water is safe, it may not be. Using a water filter straw removes as much as 99% of waterborne types of bacteria and in some cases, it will remove protozoan parasites. Having the proper water filtration system can mean the difference between good health and unnecessary sickness.

How do Water Filter Straws Work?

Water filter straws are considered a more basic filtration system compared to filtered water bottles and water filters. 

Not only are they compact and lightweight, but they are also reusable. 

The majority of water filter straws are fitted with carbon filters. These help to remove protozoan cysts or harmful bacteria that can be found in a freshwater source. They also help to make water safe to drink, whether you are drinking directly from the water source or a bottle containing unfiltered water.

Along with the carbon filter, you will find many of these straws, including a hollow fiber membrane. This helps to remove any further bacteria from the water you drink. The membrane catches the bacteria in porous tubes, allowing the filtered water to pass through. 

Also, you will find that the majority of water filter straws contain a prefilter. This feature helps to remove larger particles from the water, such as mud and silt. Not only does it help to further clean the water, but it also helps to protect both the carbon and the hollow fiber membrane filters inside the straw.

Unlike a regular water filter that often uses a pump system, with a water filter straw you need to pull the water through it yourself. Unfortunately, you may find drinking from it can prove quite tiring, but since it is such a simple system to use, no prior experience is needed. 

Key Considerations when Buying Such Equipment

Do Your Research

Before you purchase a water filter straw, make sure that you do your research. This way you’ll be able to discover the kind of bacteria, parasites, and viruses that the water you may have to drink contains. 

When it comes to water filter straws, you should choose ones that aren’t only portable but are also easy to use and can protect you against any kind of bacteria found in the area where you are traveling. 

Look At The Micron Rating 

Most water filter straws come with a micron rating of between 5 and .01 microns. This number tells you the size of particles or organisms that will get blocked by the straw filters. 

Ideally, choose one with as low a micron rating as possible. This will help to ensure that more viruses and bacteria will be caught by the filter. Some bacteria found in water can measure as little as .02 microns. So opting for straws with a .02 micron or less rating will help to prevent such from passing through the filter.

How Long Will It Last

As with other water filtration systems, the lifespan of water filter straws is measured by how many gallons of water they can filter before becoming ineffective. 

Most straws you can filter anywhere between 20 and 100,000 gallons of water before they become ineffective. This is because most come with several different filters. It is important to note that one filter inside may expire faster than another. So make sure to make a note of what kinds of filters the straws you are buying include. 

How We Chose

Despite the fact that there are many options out there for water filter straws, we wanted to give you the best overall products. This is how we did it.

Filtration Technology – At Water Filter Data, we strive to pick products that will actually benefit you and keep you safer. When it comes to filtration technology, not all water filter straws are made equally. We used as many as we could to get a feel for the process. We also took into account where these water filter straws could be used and the rate of contaminants each straw is able to filter out.

Brand Recognition – Most companies will tell you that their product is the best, but that’s not always true. We focused on brands that have a reputation for supplying quality products. We considered products that we’d want to use ourselves and factored in user reviews to choose the most quality products available.

Quality – If you’re an outdoor enthusiast or survivalist you’re going to want something dependable. We considered how long each filter lasts and how much it will cost for you to replace them.

Price – Many of the top water filter straws are in the same price range and none of them are overly expensive. That said, we considered the price of the overall unit and we factored in what it would cost to replace it.

Maintenance and Durability

The straw is directly subjected to contaminated water, sometimes as sedimented as lake water. The tiny filter pores of these small filtration devices can easily clog up. Keeping this in mind, we have only selected products that have an easy maintenance routine and last through multiple uses. 

Filtration Speed

A good filtration speed allows you to filter out a large amount of water quickly which is great when you’re camping or hiking. Most products that we reviewed have a high filtration rate despite small pores that trap almost every type of contaminant. 

Quality of Taste

While you may not travel with a water test kit, you can certainly tell the difference through taste. Clean and pure water is tasteless. The straw filters listed above will not only filter out the contaminants but also enhance its taste in an instant. 


If you’re looking for a water filter straw, it’s obvious you’re shopping for one for outdoor use. Whether it’s regular travelling or camping, it needs to be portable to be convenient to use. That’s why we’ve ensured that all the products we listed come in compact, travel-friendly designs.
