What is the safest & healthiest water bottle to use? 

In this article, you can find 9 safe water bottle options, and you will learn how to determine if a water bottle is healthy for long-term use.

The water bottles will be divided into three categories:

  • Water bottles with purification systems or filters
  • Stainless steel water bottles
  • Other plastic-free water bottles

We will also go through some frequently asked questions, such as:

  • Which reusable bottle is the safest?
  • Which is the best water bottle?
  • What is the healthiest material for a reusable water bottle?
  • How to clean your water bottle? (3 zero waste ways)

Okay, now let’s begin!

9 Of The Safest & Healthiest Water Bottles:

1. GRAYL GeoPress purifier

GRAYL water bottles are one of my all-time favorite options when it comes to health.

GRAYL GeoPress is an incredible bottle that purifies water from viruses and bacteria.

It will remove nasty things such as pesticides, chemicals, heavy metals, and even microplastics. 

GeoPress purifier will also improve the water’s taste, smell, and clarity. It can hold 24 ounces (710 ml). It is an ideal choice if you travel (or live) in an area with undrinkable water.

The bottle is made with polypropylene. The key difference between polypropylene and plastic is that it can produce crystal clear material from polypropylene, whereas plastic material is not usually clear. 


  • GeoPress offers a zero-waste cartridge recycling program
  • Ideal for hiking and camping
  • Practical and durable
  • Different sizes
  • Non-slip surfaces
  • 10-year warranty
  • 1% of every sale goes to environmental charities


  • It is on the pricier side, and the cartridge needs to be replaced periodically

2. Brita Water Bottle

Brita is a double-wall, filtering, and insulated 20 oz stainless steel bottle.

It includes a carbon filter, which reduces chlorine, and improves the taste & odor of the water.

The filter lasts about 2-3 months; after that, you have to change it. Their stainless steel bottles should be hand-washed with mild soap.


  • Built-in carrying loop
  • One-handed push button lid
  • Keeps water cold for up to 24 hours
  • Easy to replace and insert the filter
  • Affordable filters 
  • Convenient


  • You have to change the filters every 2-3 months

3. Crazy Cap UV Bottle

The Crazy Cap UV will purify water from any water source, which makes it another great, healthy, and safe choice.

It eliminates microbes and germs with a push of a button!

The cap is easy to charge and compatible with many popular bottle brands and their sizes.

Furthermore, the cap will last you at least 500,000 water treatments. A single charge can last you a whole week.


  • 99.9% water purification
  • A self-cleaning bottle
  • Compatible with other water bottles
  • Easy to use – no need for replacement filters
  • From each purchase, they donate 5% to water.org


  • A bit pricey

4. LifeStraw Water Filter Bottle

LifeStraw purifies and removers 99.99999% of bacteria, parasites, microplastics, chlorine, organic chemicals, sand, dirt, and turbidity.

The filter will provide you with healthy drinkable water wherever you are. The bottle is extremely durable, and it also improves the taste of the water.

It can filter up to 4,000 liters of water, has a double wall, and keeps water at a cool temperature all day. 

While LifeStraw has a couple of different water bottle options made with plastic, this model is made with stainless steel (but keep in mind that the filter is still plastic).


  • For every LifeStraw product purchased, a school child in need receives safe water for an entire school year
  • It is rigorously & independently lab tested
  • Designed for long-term use
  • Ideal for hiking and camping


  • You should change the charcoal filter every 3 or so months

5. Klean Kanteen Water Bottle

Klean Kanteen uses only 3 sustainably harvested materials for their bottle:

  • bamboo (the cap)
  • stainless steel
  • and food-grade silicone

Their goal is to reduce single-use plastics, so make their products guaranteed to hold up to “whatever life throws at them”.

This model is 16 oz, lightweight SINGLE WALL, which makes it perfect for everyday hydration.

Additionally, Klean Kanteen is a CERTIFIED 1% FOR THE PLANET member and B-CORP company.


  • Lifetime warranty 
  • High-quality
  • Durable & lightweight
  • Sustainably sourced


  • It is a single wall and it won’t keep the liquid cold/warm for long (however, they also have double-walled water bottles on Amazon)

6. YETI Water Bottle

Yeti is another excellent affordable 26 oz stainless steel water bottle.

It has a very wide cap, making it easy to clean.

Yeti water bottles are double-wall vacuum isolated and made with kitchen-grade stainless steel.

The bottle is dishwasher safe, and you can pick from various sizes and shapes.

So, if this one is a bit too big for you, I recommend checking some of their other options.


  • Different sizes (kid bottles, too)
  • Affordable
  • Easy to clean
  • Keeps the liquid cold for a long time
  • Leakproof cap


  • Not ideal for walking around since it is a bit too big (you can check smaller sizes on Amazon)

7. Hydro Flask

Hydro Flask is double-walled, so it will keep your liquids cold for up to 24 hours and hot for about 6 hours. 

It has a special coating that is easy-grip & sweat-free.

If you want freezing water, put some ice cubes – do not put it in the freezer.

They have different sizes, including 18, 21, and 24 oz.


  • Easy to clean
  • Well isolated – keeps the water cold for up to 24 hours 
  • Doesn’t sweat
  • Durable and easy to carry due to the handle
  • A lifetime warranty 


  • The lifetime warranty does not cover scratches 

8. Love Glass Water Bottle

Love Mandala Water bottle is 16.9 oz (500ml), made with recycled glass, stainless steel, ceramic & silicone lid. 

The bottle is chemical-free, leak-proof, durable, and lightweight.

Love Bottle donates 5% of every purchase to Global Water, which helps bring safe drinking water to those who need it.


  • Leakproof, scratch-resistant, and dishwasher safe
  • A wide range of different designs


  • Not as strong as other materials
  • Not ideal for hikes or more rough outdoor activities

9. Nomader Collapsible Water Bottle

This silicone leak-proof reusable bottle has a great design and is ideal for travelers.

It is toxin-free and made with BPA-free silicone.

Once unrolled, it retains its shape, making it easy to grip, drink from, or clean. The fluid capacity is 22 oz.

The best way to clean it is with warm soapy water.


  • Secured leak-free cap
  • Lifetime warranty
  • Freezable & heat resistant
  • 100% non-toxic materials
  • Great for hikes and traveling


  • A bit hard to fold
  • If the water is too long in the bottle, it may have an odd taste


Which reusable bottle is the safest?

Glass and stainless steel water bottles are the safest options. After that, it’s – silicon and aluminum. Lastly, it is a reusable plastic bottle.

Which is the best water bottle?

There isn’t a “best” one. The main differences between these water bottles are the specifications, design, size, materials, and ethics of the companies. 

  • The most environmentally friendly and ethical water bottle: Klean Kanteen and GRAYL.
  • The cheapest water bottle: Nomader Collapsible Water Bottle & Love Water Bottle.
  • The healthiest water bottle: Purifying bottles like GRAYL, CrazyCap & Brita.
  • The best travel water bottle: GRAYL or Nomader Collapsible Water Bottle.
  • The best water bottle for kids: 12 oz YETI.
  • The best to keep the water cold: Hydro Flask, or YETI.
  • The best bottle that doesn’t change the water taste: Love Water Bottle and the purifying bottles – GRAYL, Brita, Crazy Cap.

Each water bottle brand may have different pros and cons, depending on what you are looking for. 

What is the healthiest and the best material for a reusable water bottle?

Stainless steel is the best material; it is durable, chemical-free, toxin-free, long-lasting, isolated, light, odorless, and taste resistant. Glass is another great option, since it doesn’t get affected by any flavor, giving it a “purity of taste” benefit; however, it isn’t as durable as stainless steel.

What Is The Healthiest Water Bottle To Use? - Almost Zero Waste

How to clean your water bottle for everyday use?

For everyday washes:

  • Use warm, soapy water and fill the bottle halfway.
  • Place the cap and give it a good shake.
  • Remove the cap and empty the bottle.
  • If you have a brush, use it to reach the bottom of the container.
  • Once done, scrub, and wash the water bottle in warm water until you remove all the soap bubbles.
  • Wash the exterior of the bottle as well. Let it dry thoroughly.

How to deep-clean your water bottle, once in a while?

You can deep-clean your water bottle with distilled white vinegar or baking soda.

Option 1 – With vinegar:

  • Fill your bottle with equal parts of distilled white vinegar water.
  • Put on the cap and give it a few shakes before letting it sit throughout the night.
  • The next day, be sure to rinse out the water bottle and the lid thoroughly with warm water. Let it dry.

Option 2 – With baking soda:

  • Mix 2-3 tablespoons of baking soda with warm water to form a scrubbing paste. 
  • Dip the bristles of a long brush in the paste. Then start scrubbing the inside of the bottle. This works great if there are some stains you want to remove. Repeat until stains disappear.
  • Remove the paste with warm, soapy water and leave the bottle dry.

Side notes:

Do not use bleach or chlorine to clean your water bottle. Those chemicals may ruin the material and rust the stainless steel.

Additionally, if you order anything from Amazon, it is best to first contact their customer service, and ask them if it will be possible to ship future orders in 100% recyclable, plastic-free packaging. 

Sum up

As you can see, there are amazing, reusable, and safe water bottle brands, for different needs.

Do you have another recommendation, or do you have a different water bottle?

  1. Hey, great article, thanks! What are your thoughts on the Frank Green water bottles? On the website they say they are ‘durable stainless steel and ceramic lined as well as being bpa free, fda & eu approved.’ Have you used them/heard? I thought ceramic has the potential to be toxic.

    1. Hi Hannah, glad you like the article! I haven’t heard of them, but I checked their bottles, and they seem alright. 🙂 My favorite water bottles are from Grayl; I own one and I think they are a fantastic option.

  2. I love a Takeya bottle. Seems to have all the benefits one would want, various sizes proven to stay cold 24 AND hot for 12. I’ve noticed that several reviewers do ‘y mention it.
