Let's dive into a detailed Momcozy breast pump models comparison.
Newest Model - Momcozy Air 1
Momcozy Air 1
The Momcozy Air 1 was crafted for one primary purpose: ultimate discretion. It is the thinnest, most premium wearable pump we've ever designed, made for the mom who needs to pump absolutely anywhere without a second thought. It's the pump that is truly "in-bra, under the radar".
Design, Flange, and Milk Collector
The slim profile of the Air 1 is its defining feature, allowing it to be worn under clothing almost invisibly. But its design is about more than just aesthetics. We integrated a transparent top-view window, which solves one of the biggest challenges of wearable pumps: nipple alignment. You can look down and ensure perfect placement every time, optimizing efficiency and preventing discomfort.
The flanges are made from an incredibly soft 50A silicone, designed to gently conform to all breast shapes and sizes for a secure, comfortable, and leak-free fit.
Motor, Suction, Modes, and Pumping Settings
The Air 1 is as smart as it is sleek. It features an ultra-quiet motor that operates at less than 45dB, so you can pump confidently in a silent room or on a work call. It integrates fully with the Momcozy app, allowing you to switch modes, track sessions in real-time, and even get notifications when the collector is full.
Perhaps its most convenient feature is the wireless charging case. This case doesn't just store your pumps; it charges them. A single charge of the case can provide up to 15 pumping sessions or 5 days of use, effectively eliminating cord clutter from your daily routine.
What is Momcozy Air 1 best suitable for?
The Air 1 is the ideal choice for the busy, modern mom who prioritizes discretion. This is for the executive pumping in an open-plan office, the mom running errands, or the parent who wants to pump on a plane or at a social event without anyone knowing. It is our premium, high-tech, "invisible" solution.
Momcozy M Series Breast Pumps
The M Series is our "All-in-One Comfort" line. These pumps (M9, M6, and M5) are designed to be as simple and gentle as possible. They are all-in-one units, meaning the motor and milk collector are a single, compact piece that fits in your bra, with no external motors, tubes, or wires.
Momcozy M9
The Momcozy M9, or Mobile Flow™, is the "smart" pump designed for data-driven moms. Its defining feature is advanced app integration that puts complete control and tracking at your fingertips.
Design, Flange, and Milk Collector
The M9 features a sleek all-in-one design—motor and collector integrated into a single unit that fits discreetly in your bra with no wires or tubes. The transparent Tritan collector is durable, highly transparent, and resistant to over 100 boiling cycles, while DoubleFit™ soft silicone flanges (24mm with 17mm/19mm/21mm inserts) ensure a secure, comfortable seal. The 150ml capacity supports longer sessions without frequent emptying.
Motor, Suction, Modes, and Pumping Settings
The M9 delivers hospital-grade suction up to -300mmHg with a 3rd-gen motor operating whisper-quiet at under 42dB. Through the app, access 15 suction levels, personalized preferences, plus 2 professional modes (Milk Relief™ and Milk Boost™) and 3 standard modes. The app automatically tracks duration, output, and production trends, with alerts when sessions complete. A 12-minute quick charge provides power for one full pumping session.
What is Momcozy M9 best suitable for?
Ideal for tech-savvy moms who want optimization through data, working moms needing smart tracking and reminders, moms building supply who want to monitor trends, and anyone who prefers app-based control over manual settings.
Momcozy M6
The Momcozy M6, or Mobile Style™, balances ergonomic comfort, sleek design, and straightforward simplicity. It's built for moms who want reliable, efficient pumping without complicated features—just stylish functionality that works.
Design, Flange, and Milk Collector
The M6's streamlined, ergonomic design stays nearly invisible under clothing, tested on over 1,000 moms to ensure discreet, comfortable all-day wear. The all-in-one construction integrates motor and collector into a lightweight unit (10.12 oz) that won't weigh you down. Soft silicone flanges adapt to your breast shape for a secure seal, while the 6.09 oz capacity handles generous output. With only 4 accessories to wash, cleanup is remarkably simple.
Motor, Suction, Modes, and Pumping Settings
The M6 features a 2nd-generation motor delivering powerful suction from -285 to -300mmHg with 3 modes (Stimulation, Expression, Mixed) and 9 adjustable levels. The optimized pumping rhythm—perfected through feedback from 1,100+ moms—balances gentle suction with natural frequency for comfortable, effective sessions. Simple button controls make adjustments effortless, with no app required. The 180-minute battery provides 5-6 sessions per charge, supporting full-day freedom.
What is Momcozy M6 best suitable for?
Perfect for moms who value simplicity and ease of use, appreciate stylish ergonomic design, want straightforward controls without app connectivity, and need comfortable all-day wearability. Ideal for busy schedules requiring a "just works" solution.
Momcozy M5
The Momcozy M5 is our flagship comfort pump, designed with a unique horizontal pumping angle that mimics a baby's natural latch. It's engineered for gentle, pain-free pumping—perfect for new moms and those with sensitive nipples.
Design, Flange, and Milk Collector
The M5's revolutionary design uses a horizontal angle inspired by how babies naturally nurse, reducing discomfort while encouraging better milk flow. At just 8 ounces—only 2/3 the weight of typical pumps—it's our lightest, most discreet all-in-one option. The compact unit integrates motor and collector into a single piece that fits invisibly in your bra with no wires or tubes. Soft silicone flanges (24mm with 17mm/19mm/21mm inserts) adapt comfortably to your shape, with a generous 120ml+ capacity.
Motor, Suction, Modes, and Pumping Settings
The M5 features 3 modes including an upgraded Mixed Mode that simultaneously stimulates and expresses, helping speed letdown and support more complete drainage. With 9 adjustable suction levels and whisper-quiet operation under 50dB, you can find your perfect rhythm. The 100-120 minute battery provides 6-7 sessions per charge, with auto shut-off after 30 minutes for safety.
What is Momcozy M5 best suitable for?
Ideal for new moms starting their pumping journey, moms with sensitive nipples or previous pumping discomfort, moms prioritizing comfort over maximum power, and anyone wanting a lightweight, truly hands-free solution that's easy to use anywhere.
Momcozy V Series Breast Pumps
The V Series features a unique separated-motor design with tubing to connect the motor and milk collector. The defining characteristic of this series is its design: the motor is a separate, portable unit that connects to the in-bra collection cups via slim, discreet tubing.
Why this design? It's a breakthrough in physics. By moving the heavy motor off the breast, the in-bra collection cups become incredibly lightweight and comfortable. It also allows us to use a much larger, more powerful motor for superior performance.
Momcozy V1 Pro - Hospital grade suction breast pump
The Momcozy V1 Pro is our powerhouse and only true hospital-grade pump. Its breakthrough separated-motor design delivers maximum suction power for moms who need serious efficiency to establish or maintain full milk supply.
Design, Flange, and Milk Collector
The V1 Pro's revolutionary design separates the motor from the collection system—a portable motor unit connects to lightweight in-bra cups via slim, flexible tubing. This separation is transformative: removing the heavy motor makes the cups incredibly comfortable for extended wear while allowing for a larger, more powerful motor. The DoubleFit™ soft silicone flanges (24mm with 17mm/19mm/21mm inserts) ensure proper fit, while integrated collectors prevent milk backflow for hygienic collection.
Motor, Suction, Modes, and Pumping Settings
The V1 Pro delivers genuine hospital-grade suction up to -300mmHg—the same power found in clinical pumps. The 3rd-generation motor offers 3 fine-tuned rhythms that mimic baby's suckling patterns at different hunger levels, plus 15 adjustable suction levels for complete customization. The 2300mAh battery supports up to 9 sessions per charge, ensuring reliable performance throughout your day without constant recharging.
What is Momcozy V1 Pro best suitable for?
Ideal for exclusively pumping (EP) moms, moms of twins or multiples needing maximum efficiency, moms building or increasing supply through power pumping, and anyone requiring hospital-grade performance with mobility freedom.
Momcozy V2 Pro - Portable breast pump
The Momcozy V2 Pro features the same innovative separated-motor design as the V1 Pro, optimized for ultimate portability. It delivers powerful, efficient suction in a whisper-quiet, ultra-compact package designed for busy, on-the-go moms.
Design, Flange, and Milk Collector
Like the V1 Pro, the V2 Pro uses a separated-motor design with a lightweight, pocket-sized motor unit connecting to in-bra collection cups via slim tubing. The motor is exceptionally compact and portable, easily slipping into purses or pockets. The lightweight cups remain comfortable under clothing for discreet pumping anywhere. DoubleFit™ soft silicone flanges (24mm with 17mm/19mm/21mm inserts) provide secure, leak-free seals, while integrated collectors ensure hygienic milk collection.
Motor, Suction, Modes, and Pumping Settings
The V2 Pro delivers strong suction up to -288mmHg—powerful enough for efficient milk expression while operating at whisper-quiet levels under 48dB. It offers 3 pumping modes (including milk supply building and stimulation) and 9 adjustable suction levels, giving ample customization for comfort and efficiency. The ultra-quiet operation makes it perfect for pumping in shared spaces, during meetings, or while traveling without drawing attention.
What is Momcozy V2 Pro best suitable for?
Perfect for working moms returning to the office needing efficient pumping during breaks, moms frequently on-the-go requiring portable power, moms valuing discretion in shared spaces, and anyone wanting strong performance in a lighter, quieter package than traditional hospital-grade pumps.
Momcozy S Series Breast Pumps
The S Series is our "Classic Wearable" family. These are the beloved, reliable pumps that made Momcozy a top-selling brand in North America. In this design, the motor sits directly on top of the milk collector, creating a simple, compact, and highly effective wearable unit. They are celebrated for their powerful suction, ease of use, and fantastic value.
Momcozy S12 Pro
The Momcozy S12 Pro is the high-efficiency model of the S series. It features a clear, smart LED screen that allows you to easily see your mode, suction level, and battery life at a glance. With 3 modes and 9 suction levels, it offers a highly customizable and efficient pumping session, making it a favorite for moms who want to "set it and forget it" with confidence.
What is Momcozy S12 Pro best suitable for?
Ideal for moms who want a reliable, customizable workhorse pump with clear visual feedback, moms seeking strong suction and efficiency at an excellent value, and those who prefer straightforward controls with LED display over app connectivity.
Momcozy S9 Pro
The Momcozy S9 Pro is the workhorse of the S series, and its defining characteristic is its upgraded, long-lasting battery life. It's designed to give you more pumping sessions on a single charge than ever before. This makes it the perfect "go-bag" pump, a reliable backup, or the primary choice for a busy mom who doesn't have time to be tethered to a charger.
What is Momcozy S9 Pro best suitable for?
Perfect for busy moms who need extended battery life without frequent charging, moms wanting a reliable backup or travel pump, and anyone seeking a dependable, no-fuss wearable pump at the best value in our collection.

Your Pumping FAQs Answered
Choosing your pump is step one. Succeeding with it is step two. Here are the answers to the most common questions our pumping moms ask.
Where to buy Momcozy breast pumps?
You can purchase our full line of breast pumps, including the new Air 1, M5, and V1 Pro, directly from our official website at Momcozy.com. We also have an official store on Amazon.
We also want to make our pumps as accessible as possible. Most Momcozy breast pumps are medical devices and are HSA/FSA eligible, allowing you to purchase them using pre-tax dollars.
Can I get a Momcozy breast pump through insurance?
Yes! We are proud to have partnered with leading Durable Medical Equipment (DME) providers to help you get a Momcozy breast pump at little to no cost through your insurance. Thanks to the Affordable Care Act (ACA), most health insurance plans are required to cover the cost of a breast pump.
The process is simple:
- Verify Coverage: Contact your insurance provider to confirm your breast pump benefits.
- Obtain a Prescription: Get a prescription for a breast pump from your OBGYN or healthcare provider.
- Choose a DME Partner: We work with trusted partners like Aeroflow, 1 Natural Way, Babylist Health, and many others. You can visit our insurance page to see the full list. Your chosen DME partner will handle all the paperwork and claims for you.
How to choose the right flange size for Momcozy breast pumps?
This is the single most important factor for a comfortable and efficient pumping experience. An incorrect flange size is the number one cause of pain and can reduce your milk output.
The Golden Rule: Measure your nipple, then add 1-3mm.
Here is the correct way to measure:
- Stimulate: Gently stimulate your nipple so it perks up (do not measure a flat nipple).
- Measure: Using the nipple ruler included in your Momcozy pump set, find the hole that your nipple fits through snugly without being squeezed. Alternatively, use a ruler to measure the diameter (the width) of the base of your nipple in millimeters (mm). Do not include your areola.
- Calculate: Take your nipple measurement and add 1 to 3 millimeters to find your ideal flange size. For example, if your nipple base measures 21mm, your ideal flange size is 24mm. If your nipple measures 18mm, you should use a 21mm flange insert.
- Check Both: Your nipples may be different sizes, so be sure to measure both!
How to clean Momcozy breast pumps?
Proper hygiene is essential for your baby's health.
- The Golden Rule: Any part that comes into contact with breast milk (flanges, valves, membranes, milk collectors) must be cleaned after every single use. The pump motor and tubing (for V-series) never get washed.
-
After Every Use: Disassemble all milk-contacting parts.
- Rinse them in cool running water immediately to remove milk residue.
- Wash gently by hand in a dedicated wash basin (not the sink) with warm, soapy water.
- Rinse all parts thoroughly.
- Air Dry completely on a clean paper towel or drying rack. Do not use a cloth towel, as it can transfer germs.
- Once Per Day: All washed parts should be sterilized at least once every 24 hours. You can do this by boiling the parts, using a steam sterilizer, or using an all-in-one washer/sterilizer/dryer like the Momcozy KleanPal Pro.
- The "Fridge Hack": In a pinch, you can place your used, unwashed pump parts in a sealed, clean bag and store them in the refrigerator. This is acceptable for up to 4 hours between sessions, but it is not a replacement for cleaning. You must still wash and sterilize all parts at least once per day.
What is the warranty on Momcozy breast pumps?
We proudly stand by the quality of our products. Your Momcozy breast pump motor comes with a 1-year warranty in the US (and 2 years in the EU) from the date of delivery.
This warranty covers manufacturing defects or failures caused by "non-human factors". It does not cover normal wear-and-tear, accidental damage, or "breast pump accessories".
It's important to know that small silicone parts like valves and membranes are designed to be replaced regularly. Over time, they can stretch and wear out, which can cause a loss of suction. This is not a warranty issue! Replacing these inexpensive parts every 1-3 months will keep your pump working like new.
If you believe your pump motor has a true warranty issue, please keep your proof of purchase and contact our customer service team at support@momcozy.com.
