Portable insulin fridge buying guide

Insulin is life-critical (and expensive), which is why it’s important to have a reliable method of storing your insulin.

We’ll cover some of the things you should look for in a portable insulin fridge below, including advice on storing insulin and tips on prolonging the life of your insulin fridge.

Do you need to refrigerate insulin?

Absolutely, yes! You will need to refrigerate insulin.

Insulin is full of proteins that can go bad if they become too hot or cold or are exposed to too much sunlight. Storing insulin incorrectly can lead to it spoiling, just like food does, albeit at a slower pace.

Insulin that is not being used should be stored in the refrigerator at 36°F to 46°F (2°C to 8°C), a safe distance away from the back and top of the refrigerator where cooling elements may cause the temperature to approach freezing.

Insulin pens and vials that are “in use’ can be kept at room temperatures at a maximum of 80°F (30 °C). People do this because injecting cold insulin can sometimes be slightly painful.

How long will insulin last unrefrigerated?

As a general rule, insulin that isn’t refrigerated will last up to a maximum of 28 days at room temperature.

However, this depends on the exact type of insulin and how it’s stored, so always check with the manufacturer and try to minimize the time when your insulin is outside the fridge.

It’s better to be safe than sorry. Warm environments will make the proteins in insulin break down, so always be cautious.

Should you store insulin in a mini fridge or a standard refrigerator?

It’s best to keep your vials in a designated place instead of keeping them alongside food and drinks.

Opting for storing your insulin in a specific mini fridge has several advantages:

Managing temperature control

Compressors inside mini-fridges are smaller than ones in regular refrigerators, but they still work just as efficiently.

A mini-fridge compressor doesn’t need to handle all of the stress and foot traffic that a standard fridge does, so managing its interior temperature is a lot easier to do.

A dedicated insulin fridge will typically be better at maintaining a constant temperature than a regular fridge, which often has near-freezing temperatures at the back of the fridge where the cooling elements are.

Fewer spills

Only those with diabetes will be opening and closing the insulin fridge, which means that there are fewer chances of spills occurring.

If you store your insulin in the kitchen fridge, there’s always a risk of someone reaching for something on a high shelf, then knocking over your insulin.

Using a mini-fridge is a good way to avoid spills occurring, especially if you have younger children.

Traveling with an insulin fridge

Because of the unpredictable temperature conditions in the hold of the plane and during baggage handling, you shouldn’t pack your insulin and diabetic supplies in your checked luggage. Always pack your medical supplies in your carry-on.

This means that you should try to fit your insulin fridge in your carry-on as well, if you are keeping your insulin in the fridge during the flight.

All the insulin fridges in this review, except the Cooluli mini-fridge, are TSA-approved, so you can go through airport security checks with them.

Tips on prolonging your insulin fridge’s lifespan

If you have decided to purchase a dedicated insulin fridge, you may be worried about the device breaking down and damaging your insulin.

Here are a few tips you can do to keep your mini-fridge in good condition and lower the chance of it failing later on.

Tend to the compressor

The majority of mini-fridges are equipped with a compressor, though you may find some that are thermoelectric.

If your insulin fridge uses a compressor, this component is responsible for producing cold air. If dust builds up on the compressor, this can lead to overheating.

Overheating means the fridge needs more power to run, which costs more money and will struggle to deliver the previous temperatures that you set your mini-fridge to.

To avoid this occurring, all you need to do is clean the compressor frequently.

Regular cleaning will avoid the machine undergoing mechanical stress, keeping your insulin cool and safe from pathogens.

Air circulation

Keep your mini-fridge in a location that has lots of air circulating behind it. You can place the model near a wall, but make sure that there are at least six inches of space between it.

Your fridge’s compressor is likely to be located inside the back of the fridge near the base, though some models may have a detachable vent that covers it.

Six inches of space will avoid the compressor building up stress and overheating.

Use a fan

If it’s very hot, you can help to cool down your compressor by aiming a little desk fan in the direction of the fridge.

Position it so that the air flows behind the cooler.

Examine the gasket

Your fridge’s gasket will look like a rubber seal that is fixed inside the door. It will lie against the opening frame located on the cover.

If your gasket is broken or torn, this can lead to cool air leaking from your mini-fridge.

If this occurs, the machine will waste more energy attempting to fix the internal temperature.

Gaskets are affordable and aren’t that complicated to install. You can do this yourself by removing the old gasket from the crevice, then popping the newer one in place.

Frequently Asked Questions

Should insulin pens go in the fridge?

Yes, unopened insulin pens should be stored in the fridge.

Pens that are in use can be stored outside the fridge (you usually bring them along with you wherever you go), as long as you are careful to not get them too hot or cold.

How can I tell if my insulin has gone bad?

Good insulin will look like water, as it will be clear and color-free. If you notice that your insulin looks murky, has strands within, or develops lumps, it will have spoiled.

You should be able to notice spoiled insulin with your naked eye. If you’re doubtful, never use suspicious-looking insulin, as this can be dangerous. Throw it away and obtain a new vial/pen from your fridge.
