Best Reusable Filter Water Bottles

Welcome to week 1 of the JuneOcean Challenge, 30 days with 30 ways to help save our oceans! Each week I am taking one of the ways and going into an indepth article right here on Ocean Pancake. However, for daily updates and information join the Ocean Pancake facebook group where you can share your ideas and eco knowledge!


Before departing on my grand adventure to the Comoros, which you can read about here, one of the top things on my to do list was to purchase a sturdy waterbottle which would survive travel to the distant, middle of nowhere location my new job was in.  Moheli Island, is the smallest of the three Comoros Islands with some 35,000 inhabitants and 24h power exclusively at Laka Lodge thanks to the beauty of solar energy. I chose to get myself a pretty, blue, insulated hydroflask. Highly recommended if you do not need a filter. Here at Laka Lodge, the eco resort I work as a Scuba Diving Instructor at, depends on UV filter technology to ensure all our customers have clean drinking water.. Plastic Free!

Oh also, in case you are new here, plastic is my nemesis and I try and encourage everyone and anyone to decrease their use of plastic. Why? Just a quick overview

  • 38 billion plastic water bottles end up in landfill every year
  • That one bottle can take over 400 years to degrade
  • Just about every marine animal is in danger from injesting or becoming entangled in plastic

I have written up many posts about plastic waste management, quick and easy alternatives to plastic, how to travel plastic free, how to upcycle tshirts into bags, my favourite plastic free beauty products and how I helped rescue turtles from plastic and a full free guide to living plastic free!

I even sell ” Plastic is the Killer ” Tshirts to raise awareness and raise money for the Plastic Free fund to help clean beaches and oceans.

Why Chose a Filtered Water Bottle?

Recommending people a water bottle is the first step I take when trying to move them away from single use plastic, however some of the common complaints I received included :

  • 1. ” Tap water is acidic, while bottled is alkalinic” If you have no idea why this might be important, you can check out the post I made all about acidity and alkalinity in our bodies.
  • 2. ” What if I am travelling to an under developed country with unsafe water”

These are the two overwhelming reasons people want filtered water : to ensure it’s safe, healthy and tasty to drink.

I therefore wanted to tackle the question of the best reusable filtered water bottles, whether it may be from improving the taste of tap water, purifying chemicals found in pipes or truly drinking from potentially polluted sources.

Disclaimer* The only water bottle I have used myself out of the following ones is the BRITA water bottle, as I purchasaed one for my boyfriend to help him transition to a single use plastic free life. The other information is based from the internet, other reviews etc. I would love the opportunity to try them all! One day.

Lets start from the most hard core of the water filters, and work our way down to the basic, every day use ones.

Best Drinks from Anywhere Filters

Filters Bacteria, Viruses, Dirt and Heavy Metals.

1. Life Straw 2 Stage Filtration


I’m sure we are all familiar with Life Straw, as their marketing in the past couple of years has shown them helping thousands of people in areas with poor quality water. They also make a huge range of water bottles, all worth checking out for the perfect fit.

Removes 99.999999% of waterborne bacteria (>LOG 8 reduction), including E-Coli. Removes 99.999% of waterborne protozoan parasites (>LOG 5 reduction), including Giardia & Cryptosporidium. Removes 99.999% of microplastics

The starting cost is 35$, with additional filters coming in at 15$, requiring to be changed every 4000 liters.

I also love that for every Lifestraw bottle purchased, clean water is donated to people in need!

While the Life Straw Go is designed for hikers and similar Chemicals, salt water, heavy metals and viruses will not be removed. You would need to invest in the LifeStraw Mission and LifeStraw Family 1.0 to remove 99.9999% of viruses!

2. Seychelles Filter Water Bottle


At a reasonable price of 39$, the Seychelles water filter bottle is able to eliminate 99.999% of bacteria and viruses!

They are also focused on removing radioactive contaminants from the water. So for those chernobyl enthusiastics, or doomsday preparators, or simply nuclear connoisseurs this is the perfect filter bottle at a reasonable price range.

The replacement filters carry the bulk of the cost, ending up being around 25$ from the original 30-35$. From all the searching I have done, this truly seems to be the best price for go-anywhere filter!

3. Aquamira Bottle


Starting at 29$, this is the cheapest bottle which removes parasites, bacterias and lead. It can filter 375 Liters. Can be updated to eliminate viruses with the red line filter. 12$ for basic replacement filter, or 40$ for upgraded filter.

The Frontier Flow is certified to EPA standards to remove bacteria, and parasites and NSF/ANSI-372 for lead free content.

This bottle gives a lot of flexibility in the way to use it, it’s proudly made in the USA so a good option for those American buyers to buy local!

If however, you are going to a potentially radioactive or nuclear destination, this last water bottle in the hard core filter range might be for you:


4. GRAYL  Bottle


This water bottle has a heavy-duty filter which is equipped to remove disease-causing microorganisms and make any potential water drinkable.

” The world’s most efficient and convenient purifier bottle makes safe, clean drinking water from virtually any fresh water source in the world — in only 15 seconds. “

With a steep upfront price of 60$, replacement filters are around 25$ and need to be replaced every 300 uses or 151 litres of water.

Removes 99.9999% of viruses (e.g. Hepatitis A, SARS, Rotavirus); 99.9999% of disease-causing bacteria (e.g. E. coli, Salmonella, Cholera); and 99.999% of protozoan cysts (e.g. Giardia, Cryptosporidium)

Basic Water Filters

Now, if you are a little bit less of an avid adventurer, and just want a water bottle to make your water taste nice. Here are some of the cheaper, more basic options.

  1. Brita Water Bottle

I absolutely adore this company, not only do they carry an enormous range of portable and at home products, they also have great customer service. The price is also extremely reasonable starting at 12$. Replacement water filters are at

Innovative BRITA MicroDisc Technology for up to four weeks of great tasting water


2. KOR Nava BPA Free Bottle


The KOR Nova bottle, is a reasonably priced 22$ with replacement filters requiring changing every month. It says, the 22$ include 1 Coconut Filter. Coconunt filter? Whats that? 2 new filters cost 14$.

Includes 1 Coconut Filter

This filter got me curious, so I did some more digging. One of the questions on their frequently asked page is :

Can the activated carbon filter be replaced? Or are considered disposable?

The entire filter must be replaced when it has reached the end of its useful life. We have been very careful avoid excess material in the design of the filter. Apart from coconut carbon, the filter contains only two other ingredients: a small amount of polyethylene binder and a small silicon plug (about the size of your pinky fingernail).

So, that’s a positive fact about their filters, however I am still curious about the coconut part. (Especially since I live in a coconut filled island)

So here we go, what is the filter made of?

Nava’s filter consists of small rod (about 2″ 3/4 long) made from densely packed activated carbon granules. The manufacturing process starts with coconut shells that are heated to high temperatures, which converts them into activated carbon. The carbonized shells are then ground into granules of uniform size, mixed with a small amount of polyethylene binder and formed into rods that are heated until solid. A small silicon cap is attached to the end of each rod to help optimize water flow and cushion the filter during use.

3. Bobble Classic

bobble water bottles

While this water bottle has shown up all over my research, I personally would not chose it due to the lack of carrying mechanism. I love hanging my water bottle off the outside of my backpack to maximise packing efficiency.

I will however say that the Bobble has an adorable design, and it’s many colours definitely grab attention. Which colour would you pick? Let me know down below. It costs 12$ and replacement water filters are 16$ for a two pack. The replacable carbon filter boasts to be able to handle 150 liters of water!

Bobble also has some fantastic insulated designs. Which I would consider purchasing.


So here we are! The list of the best filtered water bottles out there! Unfortunately they are all made out of plastic, but thankfully using one and reusing it many times significantly decreases our reliance on single use plastic bottles. So the next time you are travelling to an uknown water destination, just like wanting to avoid food poisoning in asia, you can have your handy filtered water bottle to bring along with you!

Lets have happy turtles, lets quit plastic!

So help the environment, your health by investing in any of these water bottles. Do you have personal experiences with any of these? Or others I forgot to mention? Let me know down below in the comments!
