Today we’re diving into the pump that seems to be everywhere: the Momcozy M5.
I wanted to review the Momcozy M5 because it is currently the bestselling wearable breast pump on Amazon.
The thing I genuinely appreciate about Momcozy is that they take user feedback on board, meaning the models evolve over time.
I’ve noticed some key improvements in the M5 over the past year, most obviously the addition of an inbuilt timer and an upgraded LED screen.
The M5 is positioned as a more budget-friendly wearable option from Momcozy, but it still retains many of the premium features the brand is known for.
Key Takeaways
- The Momcozy M5 wearable breast pump offers strong suction, quiet performance, and smart upgrades like an LED timer and micro-vibration mixed mode.
- Its hard shell travel case and four flange sizes make it highly beginner-friendly and ideal for on-the-go moms.
- The 105 degree flange angle and DoubleFit seal enhance comfort and milk flow, though proper assembly is essential to avoid leaks.
- With 120 minutes of battery life and discreet pumping under 50 dB, it’s excellent for work, meetings, and travel.
- A practical, budget-friendly choice for moms wanting premium features without the premium price.
Momcozy M5 Wearable Breast Pump Overview and First Impressions
My first impression? The packaging is absolutely stunning, and I would say it goes above and beyond any other wearable breast pump I’ve ever used.
The M5 comes nestled inside a sleek travel bag, which is then inside a smaller box, which is inside the outer box, very secure.
I love that it includes a hard shell case. If you’re a mom who travels a lot, you know you usually just have to throw pumps into your diaper bag, but this case keeps everything organized and safe. It’s truly genius product design that supports moms.
Momcozy definitely doesn’t skimp on accessories. In the box, you get the actual pumps, two charging cables (meaning you can charge both motors at the same time), extra valves for replacement, and the user manual.
Crucially, the M5 includes a nipple measuring tool, which goes all the way from 11 mm up to 26 mm. This is super helpful because you just place it on your nipple, and it helps you determine the correct flange size.
They also provide four flange sizing options right out of the box. The standard flange size is 24 mm. The package also includes 17 mm, 19 mm, and 21 mm flange inserts.
I love that Momcozy includes all four sizes with the pump so you can get started straight away with the correct fit, that makes a big difference.
Momcozy M5 Wearable Breast Pump Design and Ergonomics
The M5 is really lightweight, weighing in at just 230 grams. For work video calls or meetings, discretion is key.
I’ve found the M5 to be very quiet, operating under 50 decibels. I honestly don’t even know if you can hear it when it’s running on a lower suction level, making it one of the most silent wearable pumps I have ever used.
This is perfect if you are in an actual online meeting. The pump I have is in the quill gray color, which you can see on the buttons. I like how simple and discreet this is.
In terms of fit and comfort, the M5 has a 105 degree flange angle. This is designed to mimic a baby’s mouth positioning, aiding in comfort and overall milk flow.
The flange is a soft silicone material that lines a hard flange tunnel. It utilizes the Momcozy DoubleFit seal, which helps create a secure fit for better suction.
I do want to point out one thing: compared to some push-in models, with the M5, you need to lift the lip of the seal up and push down to ensure a proper fit.
If it’s not done properly, it can lead to leaks or wear and tear, so just be mindful of that assembly step.
Momcozy M5 Wearable Breast Pump Operation and Performance
The Momcozy M5 has up to 200 mmHg suction strength, making it a powerful wearable breast pump. It offers nine different suction levels.
The pump has four buttons: power, plus, minus, and a reverse button. The reverse button is interesting because it instantly returns the suction level from a higher setting (like 8 or 9) back down to level one.
It features three primary modes, which I think any good pump should have:
- Stimulation Mode: Quick suckling actions to initiate let-down.
- Expression Mode: Longer, drawn-out suctions to efficiently remove breast milk after let-down.
- Mixed Mode: A combination pattern of the shorter and longer suctions.
I particularly love the mixed mode feature on the M5 because it includes micro-vibration technology. There is a slight vibration in the pump designed to help loosen up milk ducts and draw out milk more efficiently.
I am thrilled about the small, but essential, upgrades Momcozy made to the LED screen. It now clearly shows the suction level, the battery usage, and, most importantly, includes an inbuilt timer that displays the session duration in minutes.
This is a huge win for me, as you always want to know your session time and you never want to run out of battery mid-pump.
Battery life is solid, offering a 120-minute runtime off a single charge. It uses USB-C charging, which is quick, taking about 2 hours to reach a full charge.
The pump automatically shuts off after 30 minutes of continuous use, which is pretty standard for most pumps.
Momcozy M5 Wearable Breast Pump Capacity and Maintenance
The milk collector holds 160 ml, or about 5.4 oz. However, Momcozy recommends only filling it to about 120 ml (4 oz) to help prevent spilling.
Once you’ve collected your milk, the pouring process is very simple and spill-proof. The cup has a convenient opening spout, so you can pour the milk out without removing the entire lid. I find this process clean and efficient.
Regarding cleaning and maintenance, the manual has been updated. The updated manual states: “Do not use pump parts in a microwave or UV sterilizer,” and that parts should not be exposed to anything above 110°C.
Since the boiling point of water is 100°C, my interpretation is that if your sterilizer operates at 100°C or slightly under 110°C, the M5 can still be used for sterilization. This is a big plus because I know many moms rely on sterilizers.
Momcozy M5 Wearable Breast Pump Final Verdict
Overall, I am a huge fan of the Momcozy M5. It is such a great option, especially because it’s a budget-friendly way to get the advanced features Momcozy is known for.
It offers simplicity while providing crucial functionality like the mixed mode with micro-vibration, the 105-degree comfort angle, and those invaluable updated features like the inbuilt timer and upgraded LED screen.
The fact that it comes with a beautiful hard shell case and all those extra flanges is just smart product design that truly supports moms.
