Pura Kiki 9 oz Baby Bottle

What we like and what concerns us

Good

• Same short stainless-and-silicone fluid path as the 5 oz, in a larger size
• Pura states compatibility with most standard warmers and sterilizers
• Silicone tops are interchangeable across Pura’s line

Caution

• Construction and testing statements are Pura’s own; no independent teardown or lab report was found
• Pura’s historical lead-solder issue concerned insulated bottles; no independent test of a non-insulated Pura bottle was found

What the evidence shows

• Pura Stainless (MADE SAFE certified products collection) MADE SAFE

  The collection page lists "Kiki Infant Bottle" among Pura products with MADE SAFE certification. It shows no capacity, SKU, test data, method or detection limits, and no certification date (the year given is when the page was viewed). It is a product-line listing and does not state that the 9 oz bottle was checked for particle release, migration or absence of solder.

  Certification record. About the same product line, not this exact item.

These are independent sources we located and read. Manufacturer statements are not counted as evidence. How we weigh sources

Product identity

SKUs and UPCs come from Pura’s product data feed. Pura’s catalog numbers this 9 oz bottle with a K11 prefix.

What touches the liquid

The body material is only one part of this product. Each part below is listed with what the maker says it is made of, and whether it reaches milk, formula or water.

Construction, coatings and base

Stainless recalls involved specific products with accessible solder or a base that could detach. They don't show that stainless cups in general contain lead. What we record is whether the maker states no solder, and whether anyone independent has confirmed it.

Heat, sterilizing and dishwasher

Pura’s care page says to boil the stainless steel and silicone top components for 5 minutes (it does not address boiling the body separately), that the bottles are top-rack dishwasher safe and electric-sterilizer safe, and not to use microwave sterilizers on metal parts or put stainless bottles in a microwave. It states “Never give a child liquid at a temperature above 99°F / 37°C” and gives warming steps for non-insulated bottles. It does not say whether the hot water the CDC calls for with higher-risk infants can be poured into the bottle, so follow the CDC guidance and ask your pediatrician.

Formula preparation: The CDC says very hot water, about 158°F / 70°C, is needed to kill germs when a baby is younger than 2 months, was born prematurely or has a weakened immune system. Standard preparation otherwise follows the formula maker's instructions. Never use a microwave, and bottles must be clean and sanitized. Pathogen control for higher-risk infants takes priority over any concern about particle release, so this page never suggests cooler water for those babies. CDC, Infant Formula Preparation and Storage.

Cleanability

Four components are listed: bottle, natural-vent nipple, sleeve and travel cover. Pura says to clean with a bottle brush and to remove the metal ring of a silicone collar to clean under it. The stainless body is opaque, and Pura gives no drying guidance.

We show the facts and not a score. A CPSC recall in 2016 tied mold to an opaque, removable valve that held moisture, so hidden or narrow wet passages are worth checking on any cup.

What was tested, and what is only a claim

Independent testing of this exact product

None found as of September 30, 2026. That is missing evidence, not a finding against the product. Where a laboratory report is published, we will show the lab, method, batch, analyte, result, unit and detection limits, and we will never write a non-detect as zero.

What the manufacturer states

• BPA, BPS, phthalates, lead: 'BPA-free. BPS-free. PP-free. Phthalate-free. Lead free.' Manufacturer disclosure Pura Stainless
• Plastic: Pura states '100% Plastic-Free' with no plastic contact points. Manufacturer disclosure Pura Stainless
• Pura states its bottles and components were independently tested by 'a leading global testing lab' for BPA, lead, phthalates, nitrosamines, cadmium and PVC with no detectable levels. Manufacturer testing claim Lab not named. No report, method or detection limit is published. Pura Stainless

Background evidence about the materials (not this product)

These studies tested generic products, not this exact one. They show what is possible, and they don't show that this product releases anything or causes harm.

• Stainless steel: Prefer single-wall stainless with no solder, no interior coating and no painted surface where liquid can reach, and treat the no-solder point as a construction fact to verify. Evidence for stainless steel
• Silicone: Silicone is practical and often preferred for nipples and soft interfaces. Findings on generic silicone are background and do not establish exposure or harm from any one product. Evidence for silicone

Certifications, and their scope

History that bears on this evidence

• Pura’s insulated bottles and lead solder. Insulated Pura bottles only. It does not describe the non-insulated bottle reviewed here. Pura states that insulated bottles it made before 2017 could have a solder material containing lead, that it has used a certified lead-free solder in insulated bottles since 2017, and that its standard non-insulated bottles use no solder. A lead-testing advocate, Tamara Rubin, reports XRF screening that found a lead-containing sealing dot on the bottom of insulated Kiki bottles bought through at least January 2018, including one labelled MADE SAFE Certified, and says the issue is not relevant to Pura’s non-insulated bottles. Her account is not a regulator’s finding, gives no numeric results, and no CPSC recall of Pura bottles was found.

• What a MADE SAFE listing does and does not show. All Pura products that carry the listing. The MADE SAFE listing pages show that a product is listed as certified. They do not show test data, methods, batches or detection limits, and they do not say whether solder or base construction was assessed, so the listing cannot on its own verify a construction statement.

Recalls and legal history

No recall of this exact product was located in the sources reviewed. A recall elsewhere in the category does not apply to it.

We searched the CPSC recall database by brand on September 30, 2026. For Pura Stainless: No bottle or cup recall. The only Pura recall found is a fragrance diffuser unrelated to bottles. CPSC recall service

• Green Sprouts, CPSC 23-711: The stainless-cup lead recalls involved other brands' solder or base construction, not this bottle.

What we still don't know

• Exact-SKU metal migration was not found
• Which capacities MADE SAFE's line-level listing covers was not confirmed
• No independent test of a non-insulated Pura bottle was found, and Pura’s historical lead-solder issue concerned insulated bottles.

What would change our verdict

• An independent laboratory report or teardown for this exact bottle
• Evidence of solder, a coating or a plastic part in the fluid path

Price

Prices and stock change often. Price and retailer availability play no part in the verdict.

Independent study Published April 16, 2026. Accessed September 30, 2026. Tested migration of 35 siloxanes from 30 silicone food-contact products into food simulants under worst-case conditions and modelled exposure. Cyclic siloxanes exceeded proposed limits in several samples, particularly for children; D4 and D5 showed negligible risk while D3 raised potential concern, and 14 low-molecular-weight siloxanes (including D6 and L12) exceeded the threshold of toxicological concern across all age groups in the modelled scenarios.
