TLDR: Skip the cooler, skip the shared gross fridge. Get a Breastmilk Chiller.
A question as old as time - how do I store my breastmilk at work without using a shared fridge (ick) or a short-lived cooler and freeze packs?!
Thankfully, storage options have finally caught up to the life of a modern, working mom!
So, can you safely store milk at work without a fridge?
Yes…and easily!
According to milk storage guidelines, freshly pumped milk can be kept:
-
At room temperature for 4 hours (or up to 8 if pumped in a clean environment)
-
In a cooler or Chiller for 24 hours
The key is finding the option that gives you reliable storage while NOT adding to your stress during the workday. You want to pump, store, and go about your day.
The options include…
-
The shared work fridge: could give someone the ick factor
-
A mini fridge: can be pricey and space-consuming. Can also have unreliable temps
-
A cooler with ice packs: inconsistent cooling, low capacity, not a long chilling time
-
And last but certainly not least….a Breastmilk Chiller.
The best way to store milk at work - no fridge, no cords, no prep
A breastmilk chiller is the easiest, most modern solution for storing breastmilk at work without needing all the extra gadgets and prep that other options require. A Chiller is designed to…
-
Chill milk for hours (often much longer than a standard cooler)
-
Chill a large amount of milk
-
Allow you to pump directly into it, eliminating the need for extra bottles and bags.
PLUS, the good ones only need ice ;) which can be refilled anytime, anywhere!

We made the OG+ for exactly this reason. Because we were so over the outdated options that have held women back for decades.
Our Chiller:
-
Keeps breastmilk cold for up to 24 hours
-
Stores up to 28oz
-
Compatible with major breast pumps
-
Doubles as a bottle warmer
-
Looks like a normal bottle and can be kept in your bag or at your desk
So you can pump, store, and move on with your day - without overthinking it! There’s many other reasons why our Chiller tops the rest, but the capacity, storage time and materials used are top-notch.

General tips for cleaning pumping gear safely at work
Cleaning your gear between sessions is also another factor of pumping at work - but don’t worry, it can be simple!
-
Clean the pump parts in between sessions, either by using our portable washbasin bag, pump wipes, or cleaning sprays.
-
Clean your parts thoroughly at the end of the day with soap and water in a separate basin.
And that’s how it’s done, moms! Pumping shouldn’t hold you back from doing your job or living your life!
