I’ve tried SO many plastic free water bottles, and today I’m sharing my fave non-toxic ones for microplastic-free hydration. The best non toxic water bottles and mugs typically use 18/8 food-grade stainless steel, borosilicate glass, or pure Grade 1 titanium and are free of BPA, BPS, lead, cadmium, phthalates, heavy metals and harmful coatings.

For those who want to cut to the chase, the best everyday reusable water bottle is Taima Titanium, the best water bottle with straw is Klean Kanteen, the best travel mug is Koyasu Ti-Zero, the best kids water bottle is Hydro Flask and the best non toxic coffee mug is CURVd.

I’m breaking down what to look for and avoid, plus my brutally honest reviews on each one I tried, so you can find the best one for YOU.

Why You Should Switch to a Non-Toxic Water Bottle

There are so many water bottles and travel tumblers flooding the market, and most are made with lead, plastic and chemical coatings. They can leech microplastics and heavy metals into your drink while coming into contact with hot water or coffee daily. Who wants to knowingly consume anything harmful in any amount? There’s nobody policing or verifying what reusable water bottles are actually made of, so be sure to pick trustworthy or third party tested brands.

Popular water bottle brands like Stanley, Simple Modern, Yeti, HydroJug, and Corkcicle use lead in the construction of their bottles. You’ve even gotta watch out for BPA-free plastic, since they can contain alternative hormone disruptors like BPS or BPF. Brands that prioritize non-toxic construction include Klean Kateen, Owala and Hydro Flask.

How to Pick the Right Water Bottle

Here’s the factors you should consider when choosing a reusable water bottle.

1. Material

The best three water bottle materials are borosilicate glass, stainless steel and aerospace-grade titanium. Keep in mind the interior materials, lid and straw are what matter more than the body exterior. Genuine 18/8 stainless steel is the gold standard because it’s the most thoroughly tested, longest-established food-safe metal for drinkware with decades of use, FDA food-contact history, and affordable pricing. If not properly manufactured or coated though, lead can leach into you drink.

Glass is an inert, truly non-toxic material with no chance of aluminum or plastic linings leeching harmful materials into your drink. Many reputable brands now third party test their glass for lead and heavy metals.

Last but not least, titanium, which is my top pick & recommendation because it’s naturally sterile so no bacteria buildup or fungi growth, it’s the most biocompatible metal on earth so 100% safe for the human body, it’s insanely light (50% lighter than steel), a lot more durable than steel and glass, handles both hot, cold, acidic and carbonated drinks and has no flavor transfer or aftertaste. But you need to watch out for the cheap ones that are actually steel or an alloy with just a titanium coating, and opt for reputable brands.

2. Insulation

Double wall and vacuum insulated will keep hot drinks hot and cold drinks cold for longer, but if you don’t need that then a single wall would work fine.

3. Straw and mouthpiece

If you need a straw or mouthpiece, check the materials used and if they’re dishwasher safe to see if they fit your lifestyle.

4. Dishwasher Safe

If you’re not into hand cleaning, then check if the bottle and lid are dishwasher safe. Most people’s water bottles have a gross amount of bacteria. Reusable water bottles without complicated lids and spouts are much easier to keep clean. I hate to admit it, but I’m lazy when it comes to cleaning my water bottle so the ones without straw and mouthpieces are my preferred.

5. Protective sleeve or carry loop

Depending on whether this is for at-home use, gym, work or outdoor adventures matters, you’ll want a tumbler that’s easy and safe to carry. Check that glass water bottles are wrapped in silicone to prevent shattering. Decide if you’ll need a carry loop or travel sleeve.

The absolute safest travel tumblers and water bottles are:

• Third party tested by independent labs and verified to free of heavy metals and harmful substances (one brand I love even tests annually!)
• Completely plastic free or use BPA-free, BPS-free and BPF-free materials
• No plastic linings or mixed metal linings
• No coatings

What to Avoid

• Polycarbonate (#7) or PVC (#3) plastic: polycarbonate is made with BPA and PVC often contains phthalates.
• “BPA-free” plastic if you want zero chance of toxic exposure: many BPA free models just swap in BPS or BPF, similar endocrine-disrupting chemicals. Even BPA-free Tritan plastic can leach chemicals into your drink.
• Unlined or poorly lined aluminum: raw aluminum can leach into acidic drinks and older linings used BPA-based epoxy.
• Cheap or non-18/8 “stainless steel”: corrodes faster and sheds more nickel/chromium than genuine 18/8 (304-grade).
• Cheap titanium tumblers: Most “titanium” mugs use coatings or mixed metal lining.
• Unspecified plastic or silicone lids, straws, and gaskets: one investigation found microplastic-shedding straws and hidden lead solder dots on some bottle bottoms.
• Antimicrobial nanosilver coatings: regulated as a pesticide by the EPA
• Imported lead-glazed ceramic mugs: glazes can leach lead, especially with acidic drinks, heat, or wear.
• Repeated dishwashing of powder-coated or epoxy-lined bottles: can degrade those coatings over time, even if labeled dishwasher-safe.

I tried Koyasu Ti-Zero Pure Titanium Cup (Best for all drinks)

Koyasu makes the only aerospace-grade 100% pure titanium travel tumbler on the market that’s double-wall vacuum insulated and made without microplastics, coatings, paint or plastic liners. No mystery materials, ever. Ti-Zero Pure Titanium Cup is biocompatible, avoids bacteria buildup and fungi growth, naturally resistant to corrosion and rust, hypoallergenic, chemically inert, and BPA-free by nature with nothing ever leeching into your drink over time. It is THE lightest travel mug I’ve ever owned, which makes it so pleasant and convenient to carry around and I can confirm it’s actually leakproof. It has a versatile dual sip lid with two ways to drink: flip the tab up to sip through the mouthpiece and removable straw, or tilt to drink from the spout. The cup comes with a silicone straw you can attach underneath the lid to sip from the tab, and a fabric strap attached for easy carrying. The crystallized matte texture on the outside makes the body easy to grip and gives off mad aura.

Ti-Zero keeps drinks hot or cold without condensation, and can handle carbonated, tea, fruit and acidic drinks (lemon water for instance) since titanium doesn’t corrode. Fits in my car’s cup holder and keeps my drinks warm for at least 4 hours. This has jostled around my bag upside down and topsy turvy, and I can confirm it’s completely leak free. My drinks have a very clean, untainted taste. Overall, Koyasu is amazing for on the go hydration if you want something light, sturdy, leak proof, able to handle any type of drink, and truly non-toxic. I also have their Ti-Zen which is a smaller 12oz tumbler just for coffee and comes with its own travel sleeve.

Price: $89.99
Materials: 100% pure Grade 1 titanium body and Food-Grade Silicone and Polypropylene lid
What I love: truly non-toxic titanium tumbler for water, coffee, tea, fruit, carbonated drinks, dual sip, secure lid, totally leakproof, double wall vacuum insulated, extremely light

I Tried Taima 100% Pure Titanium Bottle

Taima Titanium makes a single-walled 100% pure titanium water bottle that’s naturally sterile so bacteria will not grow, BPA-free, biocompatible, doesn’t absorb any odors or transfer flavors and is ultra lightweight. It looks like a chic thermos and has even got a tea filter basket inside, which was a pleasant surprise because I didn’t find any mention of that on their website. The size of this makes it practical as an everyday water bottle but not for large capacity hydration. The insulation is fantastic even though it’s single-walled and it keeps my hot drinks warm for more than 6 hours. When I use it to keep my water cool out in 100 degree heat in the desert, it keeps it ice cold for the first few hours and still is a mild cool six hours later. Very impressed. There’s no tab, spout or straw to this which may be a good or bad thing for you, but one thing’s for sure – it’s very easy to keep clean. love the simplicity of this travel bottle and the sleek, minimalistic look. The main downside to Taima’s is there’s no handle or included sleeve, so it can only be held by its body.

Price: $99.95 for the 500ml bottle (17oz)
Materials: 100% pure titanium
What I love: made from 100% pure Grade 1 titanium, simple, elegant and super lightweight
What I don’t love: only comes in a thermos flask form in one size

I tried Pura Stainless Water Bottle

Pura is a true MVP in the water bottle world and makes their certified non toxic water bottles from 18/8 food-service grade (304) stainless steel with no interior lining, coating, or plastic components anywhere in the body, caps, or sleeves. The caps, sleeves, and straws are all medical-grade silicone instead of plastic. It’s also the only reusable water bottle line to hold MADE SAFE Certification, on top of FDA, CPSIA, and EU safety certifications, and the company backs the design with more than 15 patents and on-site manufacturing inspections. They’re fantastic for travel! Pura’s lineup covers the entire gamut of life stages with a system of interchangeable parts: Kiki infant bottles (5oz, 7oz, 9oz) for babies, Kiki sippy and straw bottles (9oz, 11oz) for toddlers, and Sport Mini and Big Mouth Sport bottles (11oz–22oz) for kids and adults, plus insulated lunch containers. Because the cap and sleeve system is interchangeable across sizes, a bottle can transition from an infant bottle to a sippy cup to a straw bottle as a kid grows, without buying an entirely new product each time.

I tried Keepcup Longplay Boba Cup

Keepcup makes the best non toxic iced coffee cup made of glass and third-party lab tested annually for BPA, BPS, BPF, phthalates (including DEHP), lead, cadmium, and other high concern substances. I love their Cold Cup Longplay Boba for my iced coffee, smoothie and organic matcha drinks when I’m out and about. My cold drinks actually stay cold longer, and if there’s ice, the ice melts slower. It’s very versatile, and I like using it at home as a regular glass cup too. I find this to be a very hefty and medium heavy cup, but the silicone sleeve makes it easier to grip. It’s so convenient during summer when I buy iced coffee outside and want to avoid the plastic cups and straws they use. Coffee and matcha shops simply pour directly from their jug into mine. It has a wide straw (so those boba balls don’t get stuck!) plus a press-fit lid with spillproof valve. Fits perfectly in my car’s cup holder. Keepcup has a very fun range of water bottles, travel mugs and even iced coffee cups for on the go drinking without the toxins and microplastics. Their Cork and Longplay versions are tempered glass with a cork or silicone band, the Thermal is 18/8 electropolished stainless steel, and the Original is a clear Tritan plastic (50% recycled).

Price: $21–$34 depending on the model (Original from $21, Thermal from $30, Cork from $31, Longplay from $33)
Materials: Tempered glass cup, silicone band and gasket, co-polyester sleeve, straw and straw lid. Phthalate, BPA and BPS free. 
What I love: best iced drinks cup with a straw big enough for boba
What I don’t love: Need to handle carefully because glass isn’t shatterproof and lid isn’t very secure

I tried Owala FreeSip Water Bottle

Owala’s makes their FreeSip bottles using 18/8 food-grade stainless steel with double-wall vacuum insulation, two-way spout and the whole line is BPA free, lead free and phthalate-free. They’re made of triple-layered, vacuum-insulated stainless steel, leakproof, dishwasher safe and entirely BPA, lead, and phthalate free. What sets Owala apart is the FreeSip lid, which combines a push-button straw opening with a wide-mouth swig spout. The tradeoff is the spouts and straws have crevices that can be hard to clean. I find that it’s not too heavy and easy to grip and hold onto (or I can hold onto the ring cap). Owala has a textured powder-coated finish for easier grip. The main downside to Owala’s water bottle is it can’t be used for hot drinks or carbonated drinks. While dishwasher safe, they strongly recommend handwashing.

Price range: $29.99-$34.99
Materials: Body is 18/8 food-grade stainless steel, Lid is food-safe, BPA-, BPS-, and phthalate-free polypropylene, straw and gasket is food-grade silicone and plastic. All components are BPA, lead, and phthalate free.
What I love: the two way spout for sips or chugs
What I don’t love: can’t use hot or carbonated drinks

I tried Klean Kateen 32oz TKWide with Twist Cap (best large capacity)

Klean Kateen’s 32oz TKWide with Twist Cap is the largest water bottle I own and their Twist Cap and stainless steel straw makes them the best in the game in my opinion. Klean Kateen is an OG name in the water bottle / tumbler world and widely trusted for their commitment to creating safe products. They’re made with 18/8 stainless steel, and most lines use about 90% certified post-consumer recycled steel that are third-party verified by Intertek. I love taking this on long hikes.

Klean Kanten’s leakproof Twist Cap with built-in reusable stainless steel straw with food-grade silicone tip is what sets them apart. The straw tip automatically comes out by gently twisting the cap, so it’s contactless, requires little effort and great for those without finger strength. I especially appreciated this while I had a finger injury from a dog bite and found it difficult to open lids that required force. All parts are completely dishwasher safe.

The only downside is the 32oz is very wide and not convenient to hold by the body but there is a sturdy, steel carry loop. I love that Klean Kateen is a certified B Corp, Climate Neutral Certified since 2020, and a 1% for the Planet member.

Price: $46.95
Materials: food-grade 18/8 stainless steel, silicone (for the straw tips and extenders), and BPA-free plastic for the main cap structure and swivel carry loop
What I love: large size holds lots of water, twist up spout and plastic-free stainless steel straw
What I don’t love: very bulky

I tried Lifefactory Glass Water Bottle with Active Cap

Lifefactory is a fantastic glass water bottle option that’s budget friendly. They’re wrapped in a silicone sleeve with a wide mouth opening and ring holder. Lifefactory is truly non-toxic, BPA-free, phthalate-free, lead-free, and dishwasher safe. All the materials are made in the US, the glass is made in France and the product is assembled in the US. Just know that the glass can still crack if it lands wrong on a spot the sleeve doesn’t cover, and it feels heavier than a steel or titanium bottle. This is a straightforward, no-frills glass water bottle that’s great for the gym, but not my favorite for travel since it’s heavy and not shatterproof.

Price range: $19.99-$24.99
Materials: Glass, Polypropylene Active Flip Cap, silicone sleeve
What I love: glass doesn’t transfer taste and made in the USA
What I don’t love: heavy, glass isn’t shatterproof and only a wide mouth opening to drink from

I tried Hydroflask Micro Hydro (best for kids)

Hydroflask makes a mini water bottle for those who only need something small or a kid’s tumbler (over 12 years old). This is a super compact, portable 6.7oz flask that’s light and easy to carry around, fit into a pocket, clip onto a bag with its removable strap, and just hold overall. It’s double-wall vacuum insulated, leakproof, dishwasher safe and keeps drinks cold or hot. It’s especially convenient when you want to take wine, espresso or creamer to go or when you know you’ll need a small amount of hydration. For elderly folks or people without much hand strength, this is also a more convenient option. One thing to note is there’s no mouthpiece, just a lid.

Price: $22.95
Materials: pro-grade stainless steel and BPA free materials

I tried Full Circle (budget)

Full Circle’s is a simple, no-frills stainless steel bottle that’s very budget friendly. This is a stainless steel bottle with a BPA-free Tritan mouthpiece and straw, double-wall vacuum insulated to keep drinks cold for hours without condensation. It’s got a wide mouth for easy filling and cleaning, a carry loop, and fits standard cup holders. It feels medium weight, not as light as titanium but not super heavy or bulky either and just overall has a minimalistic non-distracting look to it. I like how sturdy it feels and the mouthpiece is convenient to sip water from though it requires a bit of effort to move it up and down.

Price: $25.00
Materials: stainless steel with a BPA-free Tritan mouthpiece and straw
What I love: affordable and mouthpiece means no spills while drinking
What I don’t love: not perfect in terms of materials

Non Toxic Coffee Mug for Everyday: Curvd

Curvd is the best lead-free, cadmium-free non-toxic ceramic coffee mug I’ve tried so far that’s third party tested and verified. It’s made from kiln-fired stoneware ceramic, 100% chemical-free, dishwasher and microwave safe. There’s no heavy metals in the clay, glaze or color pigments used. I love that it has a big, easy-to-hold handle that fits all four fingers. There’s no taste transfer to my coffee or tea and zero after taste. Coffee snobs will appreciate this. Curvd’s nontoxic mugs are not mass manufactured so there’s a limited selection available, but they have 12oz and 16oz mugs in several colors.

Price: $25 for 12 oz mug

A Note on Cleaning

It’s a little pointless to swap to a non-toxic water bottle if it’s going to end up full of bacteria, I’m just sayin! A recent study showed 87% of reusable water bottles contain harmful bacteria like E. coli. Lab tests show they can even harbor 40,000 times more bacteria than a typical toilet seat. On top of that, nearly 15% of Americans clean their water bottles only a few times per month. Be sure to clean all parts of your water bottle daily! I included a more detailed tumbler cleaning FAQ at the bottom of this post.
