What to Do With Your Old Breast Pump

Medically Reviewed by Michelle Roth, BA, IBCLC
Wondering what to do with your old breast pump when you're finished pumping?

Now that you’ve hung up your breast-pumping boots, what do you do with the pump? Breast pumps are expensive, so it’d be a shame for them to find their final resting place in a landfill.

So what can you do with it then? If you’re thinking about expanding your family in the near future, you can put in storage. As long as it’s in good working condition, it should be able to serve you when the time comes.

Where does that leave those of us who are done having babies? Well, you can shove it into a corner somewhere — or you can find a better use for it.

In this article, we’ll be sharing some of the ways you can dispose of your used breast pump. However, what you choose to do with it is entirely up to you.

Why Open vs Closed System Matters

Breast pumps come in a variety of shapes, capacities, and prices, but there are really two major differences to look out for. The pump will either be a closed system breast pump or an open-system breast pump.

These differences will determine what you’re able to do with your pump once you’re done using it.

Closed System Breast Pump

These pumps have built-in barriers that completely separate the motor and the collection kit. No milk or air can get inside the motor, which essentially keeps mold, bacteria, and viruses at bay. They’re also easier to clean and sanitize.

Closed-system pumps are considered safe and can be used by more than one mom since there’s no possibility of cross-contamination. This means that there are more options for disposal as well.

Open-system Breast Pump

With an open-system breast pump, there’s no barrier between the motor and the collection kit. Breast milk can unintentionally find its way through the tubing and into the motor. Since the inside of the pump is dark, moist, and warm, it’s only a matter of time before mold starts to grow.

As you can see, the greatest drawback with this design is sanitization. It’s not entirely possible to thoroughly clean or sanitize all the parts of the pump. And it’s not only mold that you should worry about. Harmful bacteria and viruses can also find a home in open-system pumps.

If you own an open-system breast pump, it’s critical to ensure it’s cleaned well after every use, especially the parts that come into direct contact with the breasts or breast milk. Some parts, on some machines, can be directly placed into the dishwasher, others will need to be cleaned by hand.

Double-check with the manufacturer as to what’s required for your exact pump model — you definitely don’t want to ruin your go-to gadget during a cleaning session.

After cleaning, sanitizing is also a good idea.

Open-system pumps are designed for use by a single person only. Sharing or passing on the pump to another mom when you’re done nursing is highly discouraged.

Today, there’s so much information available online and in print on the potential dangers of sharing an open-system breast pump. Because of this, you’ll find many women shying away from accepting or purchasing a used one.

If you’d like to know what system your pump uses, check online or give the manufacturer a call. You can also consult an International Board Certified Lactation Consultant (IBCLC) for more information.

What To Do With An Old Breast Pump

Here are three useful things that you can actually do with your old breast pump. Keep in mind that disposal options differ between open and closed systems, but not to worry, we cover that, and more, below.

1. Recycle the Pump

For the environmentally-conscious mom, this is a more satisfying option. Recycling doesn’t just make us feel good, it helps reduce the amount of waste we put out into the environment. Electronic waste is particularly harmful as it can emit toxins that are hazardous to the land and the underground water we use (1).

Several breast pump manufacturers, including Medela and Hygeia, have effective breast pump recycling programs. Reach out to your brand’s manufacturer and find out if they accept used breast pumps for recycling (2).

It’s worth noting that pump manufacturers will only accept their own pumps. It is unlikely that they’ll recycle a pump manufactured by a different company.

Alternatively, you can search for a local appliance recycling center that will accept the pump. This might be a more convenient option than shipping it back to your manufacturer of choice.

Since recycling doesn’t involve the pump being used again, this might be the best option if you have an open-system pump.

2. Donate to Charity

Breast pumps, more often than not, cost a lot of money and are unaffordable for many mothers. If your closed-system pump is in good working condition, you could consider donating it. Perhaps a member of your family or a friend needs one.

If not, be on the lookout for someone who needs a pump. You can reach out to your local charitable organizations to see if they need breast pumps. You can also go online and find a women’s shelter or a charity that accepts used closed system pumps.

While you are looking, clean and sanitize the pump one last time, pack it, and keep it ready for send-off. There will be a grateful mom out there somewhere.

Remember, only closed system breast pumps (and not the accessories) can be donated due to the health issues mentioned above. You will find that many organizations already know this and will tell you as much.

3. Re-Sell the Pump

Let’s face it, baby stuff is expensive. That’s why I’m all for selling whatever is no longer needed, especially if it’s in good condition. If you want to recoup some of your expenses, selling the pump may be a viable option.

Again, I need to point out that you should only sell a closed-system breast pump, due to health reasons. Online local buy/sell sites such as Craigslist and VarageSale are good places to do this. Let other ads inspire you to create a great ad for your pump.

You could also check out mommy and kid-focused secondhand shops in your area that sell accessories and supplies. If all else fails, search Facebook for local mommy groups — you may be surprised at what you can sell (or buy!) on there.

4. What About the Pump Kit and Accessories?

Breast pump accessories should not be shared or sold. This is because they come into contact with the mother’s milk and can potentially pass on diseases from an infected mother.

“Clean-looking” accessories may carry yeast infections which are hard to get rid of. They may also bear other pathogens like hepatitis and cytomegalovirus which can be easily transferred to another mother.

Be sure to throw out any used accessories such as breast shields, backflow protectors, teats, cap valves, and sealing discs.

Feeling a tinge of guilt about throwing all the stuff out? Check with your local recycling center to see if there is anything they can take. Anything that they don’t accept should find its way to the trash bin.

Should I Use an Old Breast Pump?

The decision to use a secondhand breast pump will vary from one mother to the next. Should you choose to use an old breast pump, here are some things to keep in mind.

1. Choose a Breast Pump That Poses No Contamination Risk

This point is worth mentioning one more time. Both your health and your child’s health are at risk if you share an open-system pump from another mother (3).

If someone gifts you a used pump, do your research to find out if it has an open or closed system. The same principle applies when you’re buying one from an online platform.

Don’t let anyone kid you – no amount of sterilization will completely sanitize an open-system breast pump. The emotional stress and physical pain you or your baby could undergo treating a potential disease won’t be worth the purchase.

2. Motor Strength

The breast pump stimulates milk production from your breast in a similar way to your child suckling. On average, a mom will use the pump two to three times a day, over several months. As with everything else, frequent use can cause the motor to slow down.

A slow pump will not stimulate milk production as powerfully as a new one, so you may need to spend a lot more time pumping milk. If this happens, you could find yourself reaching for formula earlier than you had anticipated.

The older the pump, and the more babies it’s been used to pump for, the more likely it will lose suction over time.

3. Ease of Transportation

This is especially important for moms who travel a lot or find themselves moving around frequently. Make sure the used pump you’re getting is lightweight and easy to transport. Bulky breast pumps are inconvenient for a regular traveler and occupy too much space.

Pass It On

There’s much you can do with a used breast pump, aside from throwing it away. Depending on if it’s an open or closed system, we’ve laid the options out for you, from recycling to donating to re-selling.

Do keep in mind that open-system pumps pose health risks and should never be shared under any circumstances.
