What I love About The MomMed S21 Pump
I think the MomMed S21 is a solid budget-friendly wearable pump that gets the job done without breaking the bank. While it’s not the most advanced wearable pump out there, it delivers impressive suction up to 280mmHg and 12 adjustable suction levels, giving you the flexibility to find what works best for your body.
I personally love that it has three pumping modes (Massage, Expression, and Auto Mode) which is nice for a budget wearable breast pump. The quiet operation (under 45dB) is another plus, letting you pump without waking up your my baby or drawing too much attention in public.
One thing I like is the customizable fit. It comes in a 27mm shield, which is a big plus for those with larger nipple sizes as well as a 24mm flange, but if those don’t work for you, additional flange sizes (17mm, 19mm, 21mm, and 24mm) are available. A good fit makes all the difference in comfort and milk output, so it’s nice to have options.
The compact, all-in-one design makes it easy to toss in your bag, and the user-friendly LED display is convenient for adjusting settings without removing the pump.
The USB-C charging is super handy, especially for on-the-go moms, and the 150-minute battery life lasts about 5-6 pumping sessions before needing a recharge.
Performance and Efficiency
Powerful Suction Force
The MomMed S21 breast pump boasts a powerful suction force of up to 280mmHg, which can be easily adjusted to suit the user’s preferences. This feature allows for a customized pumping experience, ensuring optimal milk output and shorter pumping sessions. The enhanced suction capability of the S21 efficiently stimulates milk expression, making it an excellent choice for mothers looking for a high-performing breast pump.
Modes
The S21 offers three distinct modes, each designed to serve a specific purpose in the pumping process. The Massage Mode replicates the quick and shallow sucking pattern of a newborn, making it ideal for jumpstarting milk flow. The Expression Mode, on the other hand, excels at drawing out milk efficiently, making it perfect for obtaining a more substantial milk volume in each pumping session. Finally, the Auto Mode combines the benefits of both stimulation and expression modes, adapting to the user’s pumping rhythm. This automated sequence takes the guesswork out of finding the right mode, providing a hands-free and efficient pumping experience.
Adjustable Suction Levels
The MomMed S21 breast pump comes equipped with 12 adjustable suction levels, providing users with the flexibility to fine-tune the suction strength according to their comfort and milk flow requirements. This adjustability is essential, as the highest pump setting may not always be the most effective for milk production. The S21’s wide range of suction levels ensures that users can find the perfect balance between comfort and efficiency, resulting in an optimal pumping experience.

Comfort
When it comes to pumping, comfort is a crucial factor that cannot be overlooked. Nobody wants to experience discomfort or pain while pumping. Fortunately, the MomMed S21 breast pump offers several features that contribute to a comfortable pumping experience.
Comfortable Suction Levels
The MomMed S21 breast pump comes with 12 distinct suction levels, providing the user with a wide range of options to choose from. This feature allows the user to fine-tune their settings and find the perfect suction level for both comfort and milk output. It is recommended to start with a lower suction level and gradually work up to find the most comfortable suction level that produces a good output.
Customizable Fit
The S21 breast pump comes with a default 27mm silicone breast shield combined with a 24mm flange. However, MomMed offers additional flange sizes of 17mm, 19mm, 21mm, and 24mm that can be purchased separately. This feature is especially helpful for those with larger nipple sizes who may find the default flange size too large. MomMed provides a nipple size chart to assist users in determining the correct flange size. This thoughtful feature helps users find the most suitable fit, contributing to a more comfortable and efficient pumping experience.
Quiet Operation
The MomMed S21 breast pump operates quietly, generating sound levels lower than 45dB. While it is not entirely silent, the quiet operation minimizes distractions, allowing the user to pump comfortably and confidently without worrying about waking a sleeping baby. This feature makes the S21 breast pump ideal for use at home or in public places. Although the sound of the pump may be noticeable in a tranquil office setting, it is quiet enough to provide a discreet and inconspicuous pumping experience.

User-Friendliness
As I highlight in my how to use MomMed S21 breast pump guide, the S21 is designed to be user-friendly, offering several features that make it easy and convenient to use.
LED Display
The S21 is equipped with a small LED display that provides clear and intuitive information during operation. The display allows users to easily navigate through the different pumping modes and adjust the suction levels according to their preference. The curved angle of the screen makes it easy to see while it is in the bra without the need to reposition it. However, the LED screen light remains on for the entire pumping session, which may distract from its discreetness.
Customizable Pumping Settings
The S21 breast pump offers customizable pumping settings to suit specific needs. With 12 adjustable suction levels and 3 pumping modes (Stimulation/Expression/Auto), users can tailor the pumping experience to their comfort and milk flow requirements. The pump has only 3 buttons, making it very user-friendly in terms of operation.
Timer
The MomMed S21 comes with a built-in timer, making it easy to track pumping sessions.
Accessories
The S21 breast pump comes equipped with several accessories, including a convenient bra adjustment buckle feature that allows users to easily adapt the pump’s size to fit their existing bras. This eliminates the need to purchase new bras dedicated to pumping sessions. Users also get disposable milk storage bags, two charging cables, replacement diaphragms and duckbill valves, 24mm flange inserts, dust bags for the pumps, and an informative breastfeeding manual.

Collection Container
Cup Capacity
The MomMed S21 wearable pump has a roomy container capacity of 6 oz, offering ample space for storing expressed breast milk. While it can accommodate up to 6 oz, it’s advisable to pump within 4 oz for optimal efficiency. The large container is especially beneficial for mothers who need to express a substantial amount of milk during each pumping session or prefer to pump less frequently throughout the day.
Pouring Made Easy
The S21 breast pump has an easy-to-pour spout on the collection container, ensuring that users can pump without any worries about spilling a single drop of precious breast milk.
Transparent Design
The cups on the S21 breast pump are completely clear, allowing users to see the milk expression. However, when wearing the pump in the bra, users are unable to see the cups and how their expression is tracking. This means that to monitor the amount of milk being expressed at any given moment, users need to pull down their bra or interrupt their pumping session and remove the pump.
Assembly
The all-in-one design of the S21 breast pump is straightforward, with only 5 parts to the pump, making it extremely easy to disassemble and reassemble. However, some users have found that because there is no clip to hold the pump motor in place, it becomes loose over time. The silicone diaphragms need to be replaced every 4-6 months dependent on use, but there are 2 spare silicone diaphragms that come in the pack.
Portability And Battery Life
Portability
The MomMed S21 breast pump is a great option for mothers who are always on the go. It is designed with portability in mind and has a compact all-in-one design that is lightweight and easy to carry around. The pump’s wireless feature allows mothers to pump discreetly and comfortably wherever they are without worrying about being near an electrical outlet.
To add to its portability, the S21 comes with two silky soft, velvet protection bags that can easily fit into a handbag or diaper bag. This makes it easy for mothers to carry the pump around with them wherever they go.
Battery Life
The S21 breast pump offers a usage time of 150 minutes on a single charge, which is enough to support 5-6 pumping sessions. While this battery life may not be as impressive as other wearable breast pumps on the market, it is ample for a wearable breast pump.
Mothers who are planning to pump full-time may want to consider the battery life and recharge it throughout the day. However, for those who are using it on the go, the battery life is more than sufficient.
USB-C Type Charging
The MomMed S21 breast pump uses USB-C type charging, which makes it easy to charge the pump on the go. The pump fully charges within just 2.5 hours, which is not particularly fast, but it is convenient for mothers who are always on the go.
Mothers can charge the pump from their car or even their work computer, making it easy to keep the pump charged and ready for use. The USB charging ensures that mothers can easily find compatible charging cables and adapters, adding to the pump’s portability and convenience.
Auto Shut-Off Feature
The MomMed S21 breast pump comes with a 30-minute auto shut-off feature, which is a great option to have on any portable breast pump. This safety feature not only conserves battery life but also gives mothers peace of mind, knowing that the pump will automatically power down to prevent any potential issues from extended use.
The average pumping session is 15-20 minutes long, so the 30-minute auto shut-off feature is more than sufficient. Mothers can use the pump without worrying about overusing it, and the pump will power down automatically after 30 minutes.
Hygiene And Cleaning
Maintaining proper hygiene and cleanliness is crucial when using a breast pump, and the MomMed S21 is designed to simplify and enhance the cleaning process. Here are some features that make the MomMed S21 a great choice for maintaining optimal hygiene:
Closed System Design
The MomMed S21 features a closed system design that ensures breast milk remains isolated from the tubing and motor during pumping. This feature plays a crucial role in maintaining the hygiene and cleanliness of the breast pump, as it effectively prevents any potential contamination or bacteria buildup in the pump’s internal components. The closed system design also helps to prevent milk leakages, making the MomMed S21 a reliable and efficient pump.
BPA-Free And Food-Grade Materials
The MomMed S21 is made from premium materials, including food grade silicone and is BPA free. This ensures that the breast pump is safe for both the mother and baby, and that no harmful chemicals will be present in the breast milk.
Cleaning
The cleaning process for the MomMed S21 is designed to be simple and hassle-free. After each use, the detachable parts can be placed into the dishwasher for easy cleaning. Alternatively, you can rinse them in warm, soapy water, followed by a thorough rinse with clean water. Cleaning all the components that come into contact with breast milk is crucial to prevent the growth of bacteria and ensure optimal hygiene.
Regular Maintenance
Regular maintenance is crucial for ensuring the hygiene and efficiency of your breast pump during each pumping session. The MomMed S21 comes with a manual that provides transparency on the regular replacement of parts. Silicone breast shields need to be replaced every 4 to 6 months, silicone diaphragms need to be replaced every 4 to 6 months, and duckbill valves need to be replaced every 1.5 to 2 months. MomMed has supplied a year’s worth of replacement pump parts in their pack, making it easy and convenient for mothers to maintain their breast pump.
In conclusion, the MomMed S21 is a great choice for mothers who want a breast pump that is easy to clean and maintain, while also ensuring optimal hygiene and safety for both mother and baby.

Overall, the MomMed S21 offers excellent value for money and is a great option for moms who want an affordable, all-in-one wearable breast pump.
What I Wish Was Different
While the MomMed S21 has its advantages, it also has some drawbacks that should be taken into consideration. Here are some of the downsides to the MomMed S21 breast pump:
- Battery Life: The S21’s battery life lasts for only 150 minutes or 5-6 pumping sessions. This may not be sufficient for mothers who pump frequently or exclusively, and could result in interruptions during pumping sessions.
- LED Light Stays On: The LED screen emits a relatively low light, but it stays on for the entire pumping session. This can make the pump less discrete in certain settings.
- Lack of Advanced Features: The S21 lacks certain advanced features that are offered by more expensive breast pumps. For example, it does not have Bluetooth connectivity, mobile app integration, or more sophisticated pumping modes like vibration.
It is important to consider these downsides when deciding whether the MomMed S21 is the right breast pump for you.
The Verdict
The MomMed S21 Double Wearable Breast Pump is a great option for budget-conscious mothers who want a portable and hands-free pumping experience. Its lightweight design and quiet operation make it discreet and easy to use, while its adjustable suction levels and multiple pumping modes provide versatility and customization options.
The pump’s hospital-grade suction power, closed system design, and BPA-free and food-grade materials ensure hygiene and safety for the mother and baby. The generous container capacity also adds to its practicality.
However, the battery life of 150 minutes or up to 5-6 pumping sessions may be limiting for some users, and the LED light that stays on may be inconvenient. Additionally, the larger flange size may not be suitable for all users, and the lack of high-end features such as a tracking app or Bluetooth connectivity may be a drawback.
Overall, I think the MomMed S21 is a well-rounded and efficient breast pump that offers exceptional affordability, convenience, and practicality for breastfeeding mothers. Its easy-to-clean design with minimal parts and dishwasher safe, BPA-free silicone parts, along with its range of accessories including 24mm flanges, storage bags, nipple sizing chart, and bra adjustment buckle, make it a friendly and user-friendly option.
