Willow Go vs. Air 1: The Original vs. the Ambitious Remix
At Genuine Lactation, we test everything from “meh” to “miracle” when it comes to wearable pumps. And over in our Facebook group Wearable Pump Paperwork Prevention, one question keeps coming up:
Is the Momcozy Air 1 just a knockoff Willow Go—or did they actually improve it?
Spoiler alert: the Air 1 feels like Willow Go’s cooler, more experimental younger sibling who shows up to brunch with an app that actually works and no shame about being loud. But Willow’s been around the block, and sometimes the OG just... works.
Let’s get into the tea, shall we?
🧲 Suction Strength & Modes: Basically Twins, But One Got a Glow-Up
Both pumps go from ~70 mmHg to ~270 mmHg, which means suction strength is a tie.
But…
Willow Go gives you two modes—stimulation and expression. Simple. Predictable. Meh.
Momcozy Air 1 offers stimulation, expression, and a “mixed” mode (think short pulls followed by a long one). It also has 15 levels of control, so you can fine-tune your settings like a DJ spinning the letdown remix.
🏆 Winner for Customization: Momcozy Air 1
🔊 Vibration & Motor Vibes: Gentle Spa vs. Wild Rave
Willow Go: Gives off light spa day vibes. Vibration is there, but it’s shy. Think Spectra S1 levels of chill.
Air 1: More like full Synergy Gold energy. The vibration is aggressive—in a good way. You’ll definitely feel it, and for many, that’s exactly what helps trigger a solid letdown.
Both use that slightly loose motor-on-purpose trick to create vibration, but the Air 1 has less insulation, so the vibes hit harder. And louder- the noise is both louder and more noticeable.
🏆 Winner for Letdown Power: Momcozy Air 1
🧩 Assembly & Flange Setup: Who Designed This Puzzle?
Willow Go: Slight learning curve. If IKEA made breast pumps, this would be their starter model. Precise assembly matters—clip it wrong, and it’s Leaky Town, Population: You.
Air 1: More intuitive. Silicone flange, clamshell design, fewer opportunities to screw it up at 2 a.m. with one eye open.
Both take inserts, both have similar sizing, and both are easier than explaining lactation to a male tech startup founder.
🏆 Winner for Sanity: Momcozy Air 1
📐 Fit & Profile: Bra Friends or Bra Foes?
Willow Go: Designed to sit low and blend with your natural breast curve. Feels lighter in-bra, especially with a good pumping bra.
Air 1: Smaller overall, but shaped a little differently—it hugs the top curve more. Depending on your shape, it might sit better... or feel a little awkward.
🏆 Winner for Discreet Fit: Tie (test it in your bra to know for sure)
🔇 Noise Levels: Do You Like Attention?
Willow Go: Quiet. Subtle. Basically the introvert of pumps. You can wear it in a Zoom meeting and no one will suspect a thing.
Air 1: Extrovert energy. Loud enough to make people look up and say, “What is that noise?” Especially if you’re in a quiet room.
🏆 Winner for Stealth Pumping: Willow Go
🔌 Charging Setup: Tech Trash or Total Win?
Willow Go: Still using micro USB in 2025. Bold choice. It also requires proprietary cords, unless a shelf full of dead Willow Go’s is the decorating aesthetic you’re going for. Want to use a regular charger? Hope you like living dangerously.
Air 1: Comes with a rechargeable charging case and magnetic port. Love that. Downside: the base is a milk spill magnet. Don’t say we didn’t warn you.
🏆 Winner for Charging Convenience: Momcozy Air 1 (but don’t drip on it)
❄️ Fridge Hack Friendly?
Willow Go: Fridge hack FAIL. The duckbill sits on silicone, and cold milk fat turns that into a slippery slip-n-slide. Cue suction loss, sadness, and questioning your life choices.
Air 1: It’s doable. A little clunky, but not a disaster. Just pop off the parts and stash it.
🏆 Winner for Chill Moms: Momcozy Air 1
📱 App & Smart Features: One’s a Mood, the Other’s a Mess
Willow Go App: Clunky. Buggy. Updates take forever and you never quite trust that your pump will survive the process. It’s like a moody teenager—you love it, but it tests you.
Air 1 App: Surprisingly sleek. Custom programs, responsive controls, intuitive layout. It looks and works like a real luxury pump app. We were shocked. In a good way.
🏆 Winner for Tech That Doesn’t Suck (but does): Momcozy Air 1
🔁 Durability & Customer Service: Who Has Your Back?
Willow Go: Has a long history of motor failures and solid customer service. Replacement parts are available (but pricey).
Air 1: New to the game. Some motors are already dying (yikes), BUT Momcozy has been handing out refunds like Oprah: “You get your money back! And YOU get your money back!”
No replacement parts listed yet—but they’re new. We’re watching.
🏆 Winner for Stability: Willow Go
🏆 Winner for Generosity (so far): Momcozy Air 1
💰 Price & Final Value
Both hover around $350. Neither is cheap. But they offer real portability, real pumping power, and real convenience if they work for you.
Willow Go: Known quantity. Predictable. Like your favorite takeout spot—never amazing, never terrible.
Air 1: Wild card. It might be a genius move… or a short-lived trend. But it’s spicy, it’s fun, and it’s got potential.
🎤 Final Verdict
Willow Go = Reliable, proven, and... a little boring.
Air 1 = Riskier, louder, smarter—but honestly? Kinda fun.
Choose the Willow Go if:
You want quiet sessions
You hate surprises
You don’t want the risks of new technology- who knows how the Air 1 will play out at this point. It’s just too soon to tell.
You don’t want to worry about replacement parts or future availability
Choose the Air 1 if:
You love customization
You want stronger vibration and smarter tech
You’re okay with a little chaos in exchange for potential greatness
