Plastic baby bottles shed 1.6 million microplastic particles into your baby's milk every single day. These particles are made from petroleum-based polymers containing BPA, BPS, BPF, phthalates, and other endocrine-disrupting compounds. When you heat formula to the recommended 70°C, particle release increases by 55-fold. As your baby drinks, these microscopic plastic fragments - 1,000 times smaller than human hair width - are absorbed through their digestive system.

Here's the proof: A 2020 Trinity College Dublin study published in Nature Food (https://www.nature.com/articles/s43016-020-00171-y) tested plastic bottles under normal use conditions and found they release up to 16.2 million particles per liter.

The consequences are alarming. These particles cross the blood-brain barrier during critical neural development. They accumulate in organs. They've been found in 100% of infant stool samples at concentrations 10 times higher than in adults. Your baby consumes approximately 584 million plastic particles in their first year from bottles alone.

Even "BPA-free" bottles are deceptive - manufacturers simply replaced BPA with BPS and BPF, which cause similar hormone disruption. Recent studies link microplastic exposure to developmental delays, immune system dysfunction, and metabolic disorders.

Beyond health impacts, plastic bottles require replacement every 3-4 months as they degrade, scratch, and harbor bacteria. This creates unnecessary expense and waste - the average baby goes through 12-15 plastic bottles in their first two years.

The solution is simple: eliminate plastic entirely. Stainless steel physically cannot shed particles due to its crystalline atomic structure. It's the same material used safely in surgical instruments and medical implants for decades.

100% food-grade 304 stainless steel body with a medical-grade silicone nipple. Zero plastic components anywhere - even the collar is steel. The silicone is made from silicon (sand) + oxygen, not petroleum like plastic

The EverPure bottle is constructed from 100% food-grade 304 stainless steel - the exact same grade used in surgical instruments and medical implants. This means absolutely ZERO plastic anywhere in the bottle. While other brands claim to be "plastic-free" but hide plastic in their collars, valves, or vents, we've eliminated every trace of plastic from every component. Even our collar is pure stainless steel.

Why stainless steel? It's physically impossible for steel to shed particles. Unlike plastic's carbon-based polymer chains that constantly break down, steel has a crystalline atomic structure where atoms are permanently locked in place. No shedding means no microplastics, no BPA, no BPS, no BPF, no phthalates - zero chemical exposure, period. Steel is completely inert, meaning it doesn't react with milk, formula, or anything else your baby consumes.

The nipple is made from 100% medical-grade silicone - and this distinction matters. Silicone is NOT plastic. While plastic is made from petroleum (fossil fuels), silicone is made from silicon (derived from sand/quartz) combined with oxygen. It's essentially flexible glass. The silicon-oxygen bonds in silicone are 50% stronger than the carbon bonds in plastic, making it incredibly stable.

Medical-grade silicone is so safe it's used for heart valves and brain shunts that stay inside the human body for decades. Studies have shown ZERO particle detection from silicone even after years of use. When silicone eventually breaks down (after many years), it returns to sand, water, and carbon dioxide - not microplastics or toxic chemicals.

The result: Your baby gets pure milk and nothing else. No particles crossing the blood-brain barrier, no hormone disruption during critical development, no accumulation in organs. Just the safest possible feeding experience.

We're the only bottle with ZERO plastic anywhere. Other "steel" bottles hide plastic in collars, valves, or vents. Our steel collar design eliminates all plastic exposure. Third-party tested for heavy metals. No lead solder dots.

While both glass and steel are plastic-free, glass poses a serious safety hazard that many parents overlook until it's too late. Glass bottles can shatter from a simple drop - whether from a high chair, changing table, or even just slipping from tired hands during a 3 AM feeding. The result? Razor-sharp shards around your baby, in the diaper bag, or worse - invisible micro-fragments in the milk if the bottle cracks without fully breaking.

This isn't a hypothetical risk. Parents report horror stories of bottles breaking mid-feeding, during transport, or when older siblings knock them over. Even "shatter-resistant" glass can break under the right conditions. That's why most daycares and childcare facilities ban glass bottles entirely - the liability is too high. One accident could mean sharp glass near multiple children.

Stainless steel eliminates this danger completely. It's literally unbreakable - survives 1,000+ drops from any height. No cracks, no chips, no hidden fractures that could fail later. You can toss it in a diaper bag without wrapping it, let your baby hold it without fear, and never worry about midnight accidents when you're exhausted.

Steel is also 40% lighter than glass, making it easier for tired parents to hold during long feeding sessions and safer when babies start holding their own bottles. Glass becomes a projectile when thrown by a frustrated baby - steel just bounces.

The bottom line: Steel gives you all the purity of glass (zero plastic, zero chemicals) with none of the danger. It's the only material that's both completely non-toxic AND completely safe for real-world use with babies. No parent should have to choose between their baby's chemical safety and physical safety - with steel, you get both.
