WatertoGo v’s Lifestraw – Best Filtered Water Bottle for Travel

One of the best arguments for using a filter water bottle for travel is the resulting reduction in single-use plastic you can create. Bottled water is a huge contributor to waste, landfill and ocean plastic, especially in countries with no accessible drinking water. More than 60million plastic bottles are used a year in the US alone. That equates to about 19 bottles every second! Now imagine how many bottles are being thrown away all over the world. It is simply not sustainable.

When it comes to using a filtered water bottle in countries where the drinking water is deemed unsafe, there is an understandable level of skepticism. Drinking harmful water can have serious consequences such as viral infections and parasites. Rest assured that having sampled both of the discussed water bottles in countries where the water is not safe to drink, we are still here to tell the tale, having used only the filter to protect us. The reliability is in the science!

In this post, we will be going into detail about two leading filter water bottle manufacturers, Lifestraw and WatertoGo filtered water bottles for travel, both of whom provide a sustainable travel option to single-use plastic water bottles.

Lifestraw Go Water Filter Bottles

From the parent company of Vestergaard, comes the water filtration technology of Lifestraw. Working around the world to bring clean drinking water to local communities, Lifestraw work to provide humanitarian aid to some of the world’s most vulnerable people.

There are a wide range of products available from Lifestraw, ranging from single straws to full filtration systems, all perfect for on the go water filtration. The product we are focusing on is the Lifestraw Go bottle, a reasonably priced and very practical alternative to single-use plastic water bottles.

How it Works

Using 2-stage filtration technology consisting of a hollow-fibre microfilter, the Lifestraw Go bottle effectively removes 99.99% of bacteria, parasites, and micro-plastics. The activated carbon filter also works to remove chemicals like Chlorine and other bad tastes and odours.

Unfortunately, the filter on this bottle does not remove smaller entities such as viruses.

The filter comes as a removable entity, meaning you can still use the bottle as a refillable water bottle when there is safe drinking water available.

The Lifestraw Go bottle costs (at the time of writing) around £30GBP. The replaceable filters cost £8GBP for two carbon filters or £20GBP for the 2-stage filter.


The hollow-fibre membrane of the Lifestraw Go bottle lasts for 1000 litres of water, or roughly 6 months of travel. The carbon filter lasts 100L, or one month, however, this feature is not imperative for safe drinking water as it namely just removes bad taste.


The BPA-free bottle comes in a 650mL volume. It also comes with a handy carabiner clip to attach to the outside of your bag for easy access.


Delivery from the Lifestraw website is only available on the US mainland, however, there are a number of retailers around the world that deliver worldwide.

How Lifestraw Make a Difference

Every product that you purchase from Lifestraw goes towards providing a school child safe drinking water for a year. Lifestraw is also active in responding to global emergencies by providing safe drinking water to disaster-stricken areas around the world.

Read more about the projects that Lifestraw supports, such as the Guinea worm eradication project, over on their website.

Overall Review

We used the Lifestraw Go bottles all throughout our European adventure, making use of the filter in situations where there was no access to safe drinking water, such as on trains or on hikes. We loved the aesthetic and functionality of the bottle, as we were able to attach it to the outside of our bag for easy access. However, the nozzle of the bottle is prone to leakage as the seal wears down over time.

The lack of treatment for viruses by the filter means it is not your All-in-One drinking water source, however, for areas that are not troubled with viral contamination these bottles are perfect. There is also no information on the Lifestraw products about the recyclability of the used filters.

WatertoGo Water Filter Bottles

Water to Go is a European company that aim to reduce the environmental damage caused by the plastic water bottle crisis we are in. As well as saving on plastic consumption, over time consumers will save a lot of money from this one time purchase as well as protecting their bodies from harmful water.

WatertoGo’s vision is to simultaneously provide the entire world with safe and accessible drinking water, whilst also reducing the unsustainable amount of single-use plastic that we rely on throughout the world.

Although the WatertoGo range is still only small, the products they feature are hugely useful for water filtration on the go. They produce two sizes of water bottles and use one type of replaceable filter.

How it Works

The 3-stage filter of the WatertoGo water filter bottles removes up to 99.99% of ALL microbiological contaminants in water sources. Using 1 traditional filter and 2 nano-filter technologies, these filters remove viruses, bacteria, parasites and other harmful metals and chemicals.

The filter consists of a mechanical filter that simply blocks the passage of larger contaminants, an electrical charge that acts to further reduce pore size and trap contaminants like a magnet, and activated carbon technology that traps other contaminants and reduces bad odour and taste.

The filter comes as a removable entity and is also fully recyclable, with a recyclable plastic casing protecting the compostable carbon filter.




A WatertoGo water bottle costs between £15GBP and £30GBP depending on the size you want. The replacement parts cost £10 for the small and £20 for the large.


The nanofilters on the WatertoGo filter bottles will last roughly 200L (750mL bottle) or 130L (500mL bottle), which equats to around 2-3 months of usage. The filters work out at around 5p per litre of clean drinking water.


The WatertoGo bottles come in two sizes, 750mL and 500mL. We found the larger bottle to be fantastic, as it allows you to carry a good amount of water with you at all times. Unfortunately, there is no carabiner on the outside of the water bottle for easy storage.


Although they are based in the UK, WatertoGo have a huge range of distributors all across the globe. Check out their full list of countries here, or simply shop online and bag yourself a 15% discount.

Overall Review

The WatertoGo bottles provide the all-in-one water filtration that you will need for any trip. Removing ALL dangerous bacteria, viruses and other pollutants from any source of water, they are the best way to stay safe on the road. The filters may only last a maximum of 200L, however, they are also very affordable and are completely recyclable, meaning they are very environmentally friendly.

The one improvement that can be made to the bottles is the addition of a carabiner to the outside of the bottle to allow for easy storage whilst out and about. Despite this, we would highly recommend WatertoGo as the best-filtered water bottle for travel.


Out of the two filtered water bottles, the WatertoGo bottle is the clear winner. The much superior filtration technology removes the need for any additional treatment of water, giving an all-in-one solution to clean drinking water. It is not only affordable, but it is also very environmentally friendly, with each recyclable filter treating up to 200L of water, equalling out to 5p per litre.

Despite the WatertoGo bottle being our favourite, we would still recommend adding the Lifestraw bottle to your essential travel kit if you are not interested in complete water treatment. The Lifestraw bottle is an ideal size and features great usability. The filter lasts for up to 6 months and removes larger contaminants such as bacteria and parasites.

FAQs on the Best Filter Water Bottle for Travel

What is the difference between Lifestraw and WatertoGo?

The main difference between the two brands is the level of filtration that the standard filters deliver. The nano-filtration tech in the WatertoGo bottles filters out smaller substances than the micro-filtration tech of the Lifestraw bottle. This means that the WatertoGo filters provide a better level of filtration.

Can I really trust the water filters?

It is always a nerve-wracking experience using a water filter for the first time in a country where the water is undrinkable, however, after using both Lifestraw and WatertoGo for over a month in very questionable conditions, neither of us experienced any problems. The filters really do provide clean and reliable drinking water in places where the water is otherwise undrinkable.

What filtered water bottle is the best?

In terms of environmental friendliness and all-round water filtration, WatertoGo is the clear winner out of these two filtered water bottles. It not only delivers filtration from smaller particulates, such as viruses but the spent filters are also recyclable and compostable.

    Can you use the Water to Go bottle without its filter when drinking safe tap water/water which does not need filtering? It would be great to bring just one bottle with me on my travels and presumably removing the filer when not needed would extend its life? Thanks!

    1. highlands2hammocks

      Hey Olivia! Yes you can. We use our bottles every single day and just add the filters in when we need to. Hope this helps!
