Your Chiller is designed so that you only need one Chiller to carry all the breastmilk that you'll likely to produce in a 20-hour period.
Using the inner chamber for storing up to 12 ounces (360ML) is super easy and just requires a few ice cubes in the outer chamber while you pump directly into the inner chamber (and upper cup if you are double pumping).
To DOUBLE your storage capacity, you will use the inner chamber for your ice (instead of putting ice in the bigger, outer chamber).  Using this method, you can store up to 24 ounces (720ML)!  You just need to remember to keep your hands clean if you touch the inner chamber and always set your inner chamber on a clean surface (the inside of your upturned up is perfect for this).  You can pump directly into the outer chamber by reattaching the connector.
All of the parts lingo can be a little confusing but a quick look at our user guide shows you all the easy storage method.  Moms using the double capacity method add ice to the inner chamber after 10 hours to ensure safe chilling over super very long or very hot days.
CONVENIENCE OF TWO CHILLERS and a BOTTLE WARMER!
But sometimes you could really use the convenience of two chillers. For some moms, they want one Chiller to chill the milk and the other to store it.  And it is always nice to have one to grab if the other is in the dishwasher! Not to mention - your Chiller is also a bottle warmer - mind blowing, we know!
That’s why we have created warmer/chiller duo - to give you two great Chillers for much less money! As a mama, you're juggling everything at once and sometimes we might forget to pop the dishwasher on or may not even have time to wash you Chiller. Having two Chillers gives you even more flexibility!
