Is It Safe to Use a Used Breast Pump?

It depends on the type of pump. Some pumps are designed for multiple users, while others are made for single use only.

Hospital-grade pumps (often rented through a provider) are built for multiple users. These pumps are designed with a closed system and strong internal barriers to prevent cross-contamination between users. These are generally safe to rent or reuse — as long as you get a new accessory kit (tubing, bottles, flanges, etc.).

Personal-use pumps, on the other hand, are typically designed for one person only. Even if you replace the accessories, there’s still a risk of milk or moisture getting into the motor if the pump doesn’t have a sealed, closed system. This can lead to mold or bacteria growth that isn’t visible from the outside — and it’s not something you want near your milk.

What’s a “Closed System” Pump — and Why Does It Matter?

A closed system pump has a barrier that prevents milk from flowing into the motor or tubing. This helps keep things more hygienic and makes the pump easier to clean and safer to share or reuse.

If you’re considering a used pump, always make sure it’s a closed system model. If you’re unsure, reach out to the manufacturer or ask a specialist (like our team at Matriarch).

Risks of Buying a Used Pump from an Unknown Source

Buying a pump secondhand from someone you don’t know — like through an online marketplace or garage sale — comes with risks:

• You don’t know how the pump was cared for or cleaned.
• The suction strength may have weakened over time.
• There may be hidden mold or bacteria.
• The warranty is likely void, and if it stops working, you’re out of luck.
  

If cost is a concern (which it often is), there are safe, affordable options — and you may be able to get a brand-new pump through your insurance, at no cost to you.

Can I Share a Pump with a Friend or Family Member?

It’s tempting, especially if the pump is barely used. If it’s a hospital-grade or certified multi-user pump with a closed system, and you get a new set of personal-use accessories, it can be safe to share.

If it’s a personal-use pump, it’s best not to take the risk, even if it looks clean or was barely used. The potential for contamination isn’t worth it.

Things to Consider Before Buying a Pump (New or Used):

• Is it a closed or open system?
  A closed system is safer, easier to clean, and better suited for reuse.
  
• How old is the pump?
  Pumps have a limited lifespan. Most manufacturers rate them for a certain number of hours or sessions. A worn-out motor can reduce suction and output.
  
• Are parts easily replaceable?
  Make sure you can still get tubing, flanges, bottles, and other accessories.
  
• Is there a warranty?
  Buying new typically gives you warranty protection in case something goes wrong.
  

Final Thoughts

If you’re considering buying or borrowing a used pump, make sure you’re choosing a closed-system, multi-user model — and always get new pump parts. When in doubt, reach out to a professional who can help you assess whether it’s safe.
