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:
- Nothing Traps Water: No valve, stopper or sealed chamber. Every piece comes apart and air-dries completely.
- Nothing Stays in the Dark: The one-piece silicone lid turns fully inside out. Every surface is out in the open.
- 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.

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.
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
"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.

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.
