- Long Lasting Reservoir - Kozii does not require that you measure or add water with each use.
- Easy to Use Timer - Simple, intuitive interface lets you know how much time is left before the meal is ready.
- Auto Shutoff - When the time is up, the warmer shuts off and completely removes the heat source from the bottle. This means no overheated bottles because your busy schedule prevented you from taking the bottle out on time!
- Universal Warming Chamber - Kozii can safely accommodate breast milk, formula, storage bags (frozen or thawed), liner bottles, plastic, glass, food jars, you name it!
- High Power Heater - Kozii's high power heater means less time is wasted warming up the water bath, and more time is devoted to warming your baby's meal at a safe, low temperature.
Growing concerns about nutrient damage, hot spots, and plastic containers that release dangerous chemicals have underscored the importance of warming meals without exposing bags and bottles to dangerous steam, hot or boiling water, or the microwave.
SAFEHeat makes the warming process safer and faster by changing the fundamental mechanism used to transfer heat to the bottle or bag. A circulating bath of warm water improves warming efficiency, allowing the use of lower temperature water without compromising warming speed. The thermostatically controlled water bath is maintained at the temperature of warm tap water, but warms a bottle as quickly as warmers that reach boiling temperatures. The result is a warmer that is fast and safe for use with any type of bottle or bag, and designed for the needs of breast milk.
SAFEHeat ensures that the contents of the warmer are brought to the same temperature every time as easily as possible. A simple, easy to read timer allows the user to set the desired warming time by simply turning the knob.
When the time is up, the warming stops completely, eliminating the risk of overheating if the bottle or bag is left in Kozii for longer than intended.
The Kiinde Kozii Breast Milk and Bottle Warmer is an ecologically friendly way to prepare a meal for your child. Kozii enables you to prepare breast milk in the most efficient and environmentally responsible manner. A common strategy for thawing/warming breast milk is to leave the bottle/bag under a running tap of warm water. This is extremely wasteful and inefficient, as most of the heat, and all the water, literally goes down the drain.
Kozii recirculates water, ensuring that no water or energy is wasted in the process. Patent pending SAFEHeat technology delivers faster warming times and no risk of overheating, unlike running water or steam warmers.
| 1. | ![]() | Insert the bag, bottle or food container in the warmer. |

Warming time depends on what type of bottle, how much milk is in the bottle, what the starting temperature is (room temperature, fridge temperature, or frozen).
It is very important that you follow the filling instructions carefully, and only add water until the water level touches the word "FULL" in the bottom of the warming chamber. The water will circulate up into the chamber during warming. Proper filling ensures that the water level will drop after warming, making sure there is no residual heating after shut off.

Excellent product!
Great Warmer!
The Kiinde works very quickly, but doesn’t overheat and is extremely simple to use. Just place the bottle in, turn the dial and you’re set. In a couple minutes the bottle is just the right temperature and the baby formula is ready. I recommend this product to any mother.

Excellent Warmer
I would strongly recommend the Kiinde Kozii. This has been one of my best baby purchases, worth every penny!
Best for Breastmilk!
I also love that it has a water reservoir, so I don’t have to add water before every use. Overall a great safe and convenient bottle warmer. Highly recommended!
Great time saver.
You can take frozen milk or formula and it will thaw quickly without overheating. It may seem a little pricey, but after using it a few times I see that it is well worth the cost.
I would definitely recommend this product to my family and friends.
Good Deal. Safe. Simple.
I also love that it is easy to use. You can fill it with water, turn the timing knob to the time you want and you don't have to worry about a mess because it won't overflow. My other warmers always seemed to make a mess.
Overall, I'd say that this is a well-made warmer that is worth every penny.
What a fantastic warmer!
It is easily the best item I've purchased as a new mother. I would strongly recommend this warmer to any friend or family member. It does exactly what it's supposed to do: warm bottles, baby food jars, breast milk bags and more!
