Backed by Science & Leading Specialists

PureSip is built to eliminate the hidden mold in your toddler's sippy cup.

In 2016 the U.S. Consumer Product Safety Commission recalled 3.1 million sippy cups because mold grew inside the valve. There were 3,066 reports of mold and 68 reports of children with diarrhea, vomiting or other symptoms. Sippy cup makers' own patents admit those valve parts are "difficult if not impossible" for the dishwasher to reach.

PureSip is different. It's not a better valve. It has no valve at all.

Why It Works:

  1. Nothing Traps Water: No valve, stopper or sealed chamber. Every piece comes apart and air-dries completely.
  2. Nothing Stays in the Dark: The one-piece silicone lid turns fully inside out. Every surface is out in the open.
  3. Nothing for Residue to Cling To: Medical-grade 316 steel is non-porous and doesn't scratch like plastic, so milk can't sink in and feed mold.

No damp. No dark. No residue. A mold-free design, with zero plastic and zero microplastics.

✓Mold-Free Design

No Hidden Valve. Nothing for Mold to Grow In.

Other sippy cups hide a rubber valve inside the lid where mold grows unseen. PureSip has none. It's just a steel cup, two silicone lids and a straw, and every piece comes apart in seconds.

Every piece of PureSip comes apart, no hidden valve

Mold Has Nowhere to Start

Mold needs trapped water, darkness and leftover milk. PureSip takes away all three.

✔No trapped water: every piece air-dries completely

✔No dark hiding spots: the lid turns fully inside out

✔No residue: smooth 316 steel milk can't sink into

How PureSip keeps mold out

"The Only Toddler Cup I Recommend to Parents"

Dr.Natasha Collins | Pediatrician

"I've seen what grows inside the valves of 'spill-proof' sippy cups, and most parents have no idea it's there. PureSip is the only toddler cup I now recommend. There's no hidden valve for mold to grow in, every piece comes apart so parents can see it's clean, and it's medical-grade steel and silicone with zero plastic. This is what safe looks like."

Why 11,000+ Parents Threw Out Their Sippy Cups

Every "spill-proof" sippy cup hides a little rubber valve inside the lid. It stays wet, it stays dark, and milk sits in it all day. It's the perfect place for mold to grow, right where your child's mouth touches.

Most moms don't find it until the valve pops loose. "I thought I was cleaning it well."

What mold can do to a toddler:

❌ Stomach upset, nausea and vomiting
❌ Diarrhea
❌ Infections in kids whose immune systems can't fight it off
❌ A body that's always fighting something

The viral story behind the 2016 recall? A dad broke open his son's cup because his little boy was always sick. The valve was full of mold.

You can't control every germ at daycare. You can control what your toddler drinks from 10 times a day.

Finally, A Cup With Nothing to Hide

PureSip has no hidden valve, no stopper and no sealed chamber. Just a steel cup, a sippy lid, a straw lid and a straw, and every piece comes apart in seconds.

The cup is medical-grade 316 stainless steel, the same steel surgeons use for implants. The lids are medical-grade silicone, made from sand, not petroleum.

Zero hidden mold. Zero plastic. Zero microplastics. Zero lead.

☑ Mold-Free Design: No Hidden Valves
☑ Every Piece Comes Apart & Turns Inside Out
☑ Medical-Grade 316 Stainless Steel
☑ Medical-Grade Silicone Lids
☑ No Lead, No Rust, No Metallic Taste
☑ Dishwasher Safe

If you can see it, you can clean it.

How PureSip Keeps Mold Out

Mold needs three things: trapped moisture, darkness and leftover milk. A valve cup gives it all three. PureSip takes every one away.

1. Nothing traps water. No valve or sealed chamber, so every piece air-dries completely.
2. Nothing stays in the dark. The lid turns fully inside out. Every surface is in the open.
3. Nothing for residue to cling to. Non-porous 316 steel doesn't scratch, so milk can't sink in.

Still leak-proof and spill-proof. The seal comes from tight-fitting silicone, not a hidden mechanism. Throw it, drop it, bang it on the highchair. The lid stays sealed.

One Cup From 6 Months to 3 Years

PureSip comes with both lids included — adapting to every stage of your toddler's development.

SIPPY MODE (6+ months)
Where it all starts. First sips on their own.

STRAW MODE (12+ months)
As they grow. Mess-free and confident.

CUP MODE (18+ months)
When they're ready. Full transition to open cup.

Unlike plastic that cracks, stains, and gets chewed up — stainless steel lasts forever. This cup will still look new when your toddler outgrows it.

The Purity of Glass. Without the Shatter Risk.

Glass is pure — but toddlers drop things. One drop on tile and you're rushing to the ER.

And most daycares ban glass entirely — forcing you back to plastic anyway.

PureSip gives you the purity of glass without the danger. Medical-grade steel is functionally indestructible. Drop it, throw it — it survives. Your child stays safe.

Daycare-approved everywhere. Your protection doesn't stop at the front door.

Trustpilot reviews

Why Thousands of Parents Made the Switch: Excellent 4.8 / 5

  • "Mold nightmare is over."

    Found disgusting mold in our 'clean' sippy cup. How long had she been drinking that? PureSip shows you everything. If you can see it, you can clean it. Will be buying more as gifts.

    Betty K. · Cleveland

  • "Hygiene I can trust."

    The hidden mold in plastic valves traumatized me. PureSip's simple design means nowhere for nastiness to hide. Actually hygienic.

    Heather L. · Miami

  • "See what you're cleaning."

    Other cups have so many hidden crevices. Mold central. PureSip inverts completely. I can see and scrub every surface. Game changer.

    One Cup. 3 Years. Zero Replacements.

    Most families replace plastic cups every few months — chewed up, cracked, stained, or moldy.

    At $10-15 each, that's $100+ over 3 years on cups that grow mold and shed plastic the entire time.

    PureSip lasts from 6 months to 3+ years. One purchase. Zero microplastics. Zero replacements.

    The durability means it survives multiple kids. Hand it down — medical-grade steel doesn't wear out.

    The real question isn't whether you can afford PureSip — it's whether you can afford to keep using plastic.

    60-Day Risk-Free Guarantee

    Try PureSip for 60 days. Watch your toddler drink happily. Check every surface after each wash and see it's actually clean.

    If you're not 100% satisfied — for any reason — return it for a full refund. No questions asked.

    We're a US-based company with real customer support. We've got you covered.

    Frequently Asked Questions

    Is PureSip mold-free?

    Yes. It's a mold-free design: no hidden valve, stopper or sealed chamber where mold can grow. Every piece comes apart and turns inside out, so you can see it's clean.

    What if I don't like it?

    You're covered by our 60-day money-back guarantee. Full refund, no questions asked.

    What's the capacity?

    8 oz / 237 ml

    What ages is PureSip designed for?

    PureSip is designed for toddlers 6 months to 3+ years. Start with the sippy lid, transition to straw, then open cup.

    Is it really leak-proof?

    Yes, from a tight medical-grade silicone seal, not a hidden valve that breeds mold. Every part inverts for cleaning.

    Is it dishwasher safe?

    Yes. Steel handles heat without shedding — unlike plastic.

    Does the straw need cleaning?

    Yes, like any straw, rinse and brush it. PureSip's straw pulls straight out with no weighted joints or sealed sections, so a brush reaches all the way through.

    Is the silicone safe?

    Yes. Medical-grade silicone is made from sand, not petroleum. It's used in heart valves.

    Is there any lead?

    Zero. PureSip is forged, not soldered — no hidden lead solder dots like the recalled cups.

    Does it have a metallic taste?

    No. 316 medical-grade steel doesn't corrode or leach like cheaper 304 steel. Water tastes like water.

    What's your return policy?

    We offer a 60-Day Risk-Free Trial. Use it for 60 nights — send it back for a full refund. No questions asked. No shipping it overseas. We're a US-based company with real customer support.

    I found black stuff inside the valve of our old cup and immediately ordered something different. I had been washing that thing every single night. With this one I can turn the lid inside out and actually check it. That was the whole reason I bought it.

    We use it for milk so cleaning was my biggest thing. The lid comes off, turns inside out, and I can wash both sides. Still clean the straw separately obviously but its all pretty straightforward.

    I was that mom saying “but I wash them every day.” Then I found mold in a piece I didn’t even realize came out. I’m much more particular now. I like that PureSip lets me look at the lid properly instead of guessing what’s inside.
