Chest Vs Upright-Which One to Choose?

You can store breast milk in both types of freezers whether it is chest or upright. These both type of freezers has its own pros and cons.

Chest freezers stand horizontally on your floor. They are deep compared to upright freezers.

The temperature in the chest freezers stays consistent for longer even during the blackout.

In the chest freezer, air doesn’t circulate much which helps to prevent freezer burn than uprights.

They are more energy-efficient, having more storage capacity, and are inexpensive than upright freezers.

But it’s actually difficult to find the breast milk bag/container you need in the chest freezer without rearranging and searching.

There is bending, lifting, and moving is needed to find the items you are searching for. It also covers more floor space.

On the other hand, upright freezers are like refrigerators. They sit vertically on the floor, so take up lesser floor space, thus useful for small houses.

They hold the items on the different shelves and compartments like refrigerators. So, they are easy to organize.

You can easily access and store the breast milk in the upright freezer.

But uprights are noisier than chest freezers. The cold air easily discharges through it every time you open the freezer door.

So, if you have small storage space, want fridge-like access, and having steady power then an upright freezer might be a better option for you.
