Parents smiling with their baby

For new parents · formula feeding

Your formula is only as clean as the water you mix it with.

Every bottle you make up is mostly tap water. Babies drink an enormous amount for their size, and their systems are still developing, so they have the least tolerance for what's in it. Boiling kills the germs, but it doesn't remove PFAS, microplastics or lead.

The routine you already have down

You sterilise everything that touches the bottle. Not what goes in it.

By week two you've got the whole ritual memorised, half of it done one-handed at 3am. Look how careful you already are.

Your bottle-making routine

  • Sterilise the bottles & teats
  • Boil the kettle
  • Cool to the right temperature
  • Level, correct scoops
  • Wash your hands first
  • Check the use-by on the tin
? What's actually in the water Untracked

Every step protects against germs. Not one of them touches the chemicals dissolved in the water itself.

The thing boiling can't fix

Boiling was never the whole answer.

Boiling kills bacteria, and that matters. But heat does nothing to the contaminants that worry parents most, and infants are the group least able to cope with them.

  • PFAS ("forever chemicals") aren't removed by boiling, and official guidance flags developmental effects in infants and children as a concern.
  • Lead can leach from older pipes and fittings, and there is no safe level for a baby. Boiling can actually concentrate it.
  • Microplastics pass straight through the kettle, and have now been detected in human blood and tissue.
  • Babies are uniquely exposed. They drink far more water per kilo than adults, through organs that are still maturing.
🍼

Council water is treated to be safe, and for most of us it's fine. What it isn't required to remove is PFAS, microplastics or lead.

For a newborn on an all-liquid diet, those are exactly the things worth taking off the table.

Before you reach for the obvious answer

Bottled water and jug filters feel safer. They're not the fix.

  • Bottled water is one of the biggest sources of microplastics there is, and some have mineral levels that aren't suitable for making up formula.
  • Supermarket jug filters mostly improve taste and chlorine. Most don't reliably remove PFAS, lead or fluoride.
  • Boiling alone handles bacteria, but leaves forever chemicals, lead and microplastics right where they were.
💡

Removing PFAS, lead and microplastics takes real, multi-stage filtration, not a plastic jug.

The easy options were never built for the contaminants that matter most to a baby.

The Waters Co difference

Start every bottle with water you can actually trust.

The BIO 1000 runs your tap water through 15 stages, removing 99% of PFAS along with lead, microplastics, chlorine and more, and holds it in a hand-blown glass reservoir with a BPA-free build. You filter first, then prepare bottles exactly as your formula tin and child health nurse advise.

  • 99% removal of PFAS, plus lead, microplastics, fluoride, chlorine & bacteria in one pass.
  • Hand-blown glass reservoir, BPA / BPB / BPS-free build, no plastic sitting in your baby's water.
  • Adds 60+ trace minerals back, so the water enriches rather than just strips.
  • Filter first, then follow your usual prep, it's a step before the bottle, never a replacement for safe preparation.

What comes out

The things you've been staring at the tap wondering about.

99%

PFAS forever chemicals

Flagged for developmental effects in infants and children.

Lead & heavy metals

Can leach from older pipes. No safe level for a baby.

Microplastics

Boiling doesn't touch them. This filters them out.

🍷

Glass reservoir

BPA / BPB / BPS-free. No plastic in your baby's water.

Chlorine & fluoride

Added at the treatment plant, filtered back out at your bench.

+60

Minerals added back

Bio-organic trace minerals your water is usually missing.

You have zero spare minutes. We know.

On the bench in minutes. No plumbing, no power.

Step one

Sit it on your kitchen bench

Three pieces, assembled by hand in a couple of minutes. It's gravity-fed and just 7kg, with no drilling, no electrician, no cupboard rearranging.

Step two

Fill the top with tap water

Gravity draws it down through all 15 stages into the glass reservoir. Keep it topped up so there's always filtered water ready for the next feed.

Step three

Filter, then make up bottles as normal

Draw from the reservoir and prepare exactly as your tin directs. One filter set lasts up to 4 years, covering bottles now and sippy cups later.

🍷

Glass, not plastic

BPA / BPB / BPS-free build.

Lasts up to 4 years

12,000L filter life, ~3c a litre.

"We're formula feeding and I kept thinking about what was in the water going into every bottle. Boiling never sat right with me because I knew it didn't remove the chemicals. This gave me back some calm on the night feeds."

"Our house is older and I was worried about lead in the pipes. Knowing the heavy metals are filtered out before it goes anywhere near the formula was the whole reason we bought it. Simple to use too."

"Bought it the week we brought her home. It sits on the bench, we filter, then make up bottles the way the tin says. The one baby thing that was genuinely easy to sort."

Honest answers

The questions new parents ask us.

Do I still need to boil the water for formula?

Yes. Always prepare formula exactly as the tin and your child health nurse advise, which usually means boiled water cooled to the right temperature. Filtering happens first, so you're simply boiling and mixing with cleaner water to start with. The BIO 1000 is a step before preparation, never a replacement for it.

Isn't bottled water safer for making up bottles?

Not necessarily. Bottled water is a major source of microplastics, and some bottled waters have mineral levels that aren't ideal for infant formula. Filtered, re-mineralised tap water lets you avoid the plastic and follow standard preparation with water you can trust.

We have older plumbing. What about lead?

The BIO 1000 filters heavy metals including lead, which can leach from older pipes and fittings. Because there's no safe level of lead for a baby, this is one of the most common reasons parents filter specifically for bottle-making.

Will it strip out minerals my baby needs?

No. Rather than stripping the water bare, the BIO 1000 re-mineralises it, adding back 60+ trace minerals. Your baby's nutrition comes from the formula itself; the filter simply cleans the water you mix it with, and you follow the tin's instructions as normal.

Is our tap water actually unsafe, then?

For most people it's treated to be safe and is fine. What council treatment isn't required to remove is PFAS, microplastics and lead from older plumbing, and infants are the most sensitive to those. That's why many parents choose to filter for the bottle years specifically, rather than out of alarm.
