Buying Guide for Water Filter Straws

As we promised earlier, we are here with a detailed buying guide containing all the major factors you should consider before purchasing a water filter straw. The market is full of all types and sizes of filter straws, but you have to choose what’s best depending on your requirements. Let us have a look at the things to keep in mind when you are up for the search for the best water filter straw.

Research Thoroughly

The most important thing to start off the journey to find the best filter is to up your research game. You can choose one of the two recommended ways. However, it is preferable to try out both for refined research.


Tip! Try to look out for the right thing by yourself because no one can understand your needs better than yourself.

Surf the internet and search for the top-selling brands and products that fit your requirements. You can also visit the market to have a close look at how these filters look. Compare both online and market rates to make a decision.


If you are always busy, you won’t want to get stuck in the research for the best quality filter. However, you will still want the best. In such cases, you can ask your trusted acquaintances, friends, and relatives to help you out. Ask them about their experience with the straw filters they are using.

It is always a good idea to buy the product people are already using and have good remarks about it.

Do You Need A Filter Or Purifier?

This is something that most of you don’t know until now. Most of the straw filters are just filters and not purifiers. It means that your straw filter will probably filter out all the harmful contaminants from the water, but won’t purify it the way you expect.

It is always a better idea to reconsider what you are really searching for. A regular filter straw will remove all types of bacteria and improves the odor and taste of the water. However, a purifier will also remove viruses from the water along with all the other particles that a filter removes. 

Major Features

The following are the major features that you need to check while finalizing your deal. It is important that the below-detailed features match your requirements.  


Check the compatibility level of your filter straw.

Do You Know! The good ones have a thread on one end of the straw so that you can easily connect it with a water bottle or drinking pouch.

This allows you to keep a stock of clean water along with you while you are on your way. You will also have to put less effort into sucking water every time you feel thirsty.


Most of the filter straws come with a complete kit so that you feel more convenient in filtering lake or river water.

Make sure that the filter you are considering buying has a storage bag, squeeze water pouch, and cleaning syringes so that cleaning, using, and carrying it will be easier. 

Micron Rating

The micron rating of a filter straw ranges between 5 microns and 0.01 micron. The smaller the micron size is the better it is for the straw to filter out the tiniest particles from contaminated water.

Bacteria and viruses can be as small as 0.2 micron that is why a small micron pore size is always recommended. 

Weight And Size 

You are looking for a water straw for a reason that they are small and easily fit in a palm. So, you must get what you are looking for.

An average filter straw weighs from 1 to 8 ounces and the size varies from 6 to 9 inches. You should choose what suits you best. 


The price of the product you are choosing makes a lot of difference in quality and durability. This is a fact that most of the filter straws are cost-friendly. They don’t go beyond the range of $10-$30.

However, if you are struggling with the bargain of a costly water filter, make sure that its functions, filter capacity, and life are as advanced as its price. Don’t go for too cheap filters because they will remove just a few contaminants.

Filter Life

Just like any other water filter, filter straws also have a life expectancy that varies according to their features and functions. These filters don’t need replacements because they expire.

Important Fact! The best of water filter straws have a shelf life of 5 years and some of them don’t have an expiration date at all.

If you are someone who cannot sit still in the house without having an outdoor adventure every month, you should look for filter straws with a longer lifespan and a sturdy design. 

Filter Capacity

The flow rate of a filter determines how much water it can filter. However, with straw filters, it depends on the filter life.

There are some filters that can filter 100,000 gallons of water with no expiration date, and some will offer some four to 5 thousand liter water for a year or two. Choose your filter wisely!


  • What Are Filter Straws?

Filter straws are a type of portable filters. These filters are small, lightweight any easy to carry. The filter straws provide direct suction from lake or river water as it filters the water while you are sucking it through the filter. 

  • How Do They Work?

The working mechanism of a water filter straw largely depends on the technology that it features. Most of the filter straws use activated carbon to absorb and block sediments, and other particulates in the filter.

However, many others use the UH hollow fiber membrane or a pre-filer. The advanced ones have all three or more than three stages of filtration that helps remove bacteria, protozoa, viruses, chemicals, sediments, silt, cysts, and other waterborne worm eggs.

The straw filters rely on your suction ability. You have to suck water through the filter because there are no suction pumps in these filters. 

  • How long can a filter straw last?

The longevity of a filter straw depends on the manufacturer’s warranty as well as its capacity. The best filter straw can last for 5 years easily. 

  • How to clean a water filter straw?

You will find the method to clean and maintain your water filter straw on the manufacturer’s instruction manual. However, you can use back-flushing or a cleaning syringe to clean it. 

  • Does a filter straw remove viruses?

No, not all the filter straws are designed with such advanced technology to remove viruses, but if your straw works as a purifier, there are chances of virus removal as well. 

  • Can all the filter straws be used with a water bottle?

Not all the filter straws have a connecting thread at the other end. If you need a filter straw to attach your water bottle as well, make sure you read the features of the product before buying. 


Finding the best filter straw is now the easiest thing to do!
