Momcozy Air 1 Breast Pump: How To Use
- Prepare Your Pump: Before using the Air 1 for the first time, charge it using the magnetic charging cable or the wireless charging case until you find the battery icon to be fully and stably lit green.
- Assemble Your Pump: Select and attach the appropriate flange size matching your anatomy. Utilize the provided precision measurement ruler to identify your correct size from the available options (17mm, 19mm, 21mm).
- Verify Optimal Positioning: Leverage the innovative transparent viewing window to confirm proper nipple centering. Your nipple should rest perfectly centered within the flange tunnel, ensuring maximum comfort and efficient milk extraction.
- Activate the Device: Engage the power button to initialize the pump system. Control options include direct device manipulation or convenient smartphone app operation.
- Configure Your Session: Choose your preferred pumping mode and intensity level through available settings. Begin conservatively with lower suction levels, progressively increasing intensity until reaching your personal comfort threshold.
- Commence Hands-Free Pumping: The pump automatically transitions between stimulation and expression cycles when utilizing app connectivity. Continue your daily activities while the device operates independently.
- Track Your Progress: Monitor milk accumulation through either the transparent viewing panel or smartphone application interface. The app delivers timely notifications when your collection container reaches capacity.
- Complete Your Session: Power down the pump system and carefully detach it from your body. Transfer expressed milk into appropriate storage vessels as required.
Momcozy Air 1 Breast Pump: How To Clean
Maintaining your Momcozy Air 1 breast pump requires straightforward cleaning procedures:
- Component Separation: Detach the milk collection container from the primary pump unit, then systematically separate the flange assembly, valve mechanism, and silicone components into individual pieces.
- Immediate Cold Rinse: Flush all breast milk-contacted parts under cool, flowing water, preventing milk residue from hardening on surfaces.
- Thorough Soap Washing: Apply warm water combined with gentle, non-abrasive dish detergent to meticulously clean all separated components. Employ a soft-bristled brush for accessing intricate areas when necessary.
- Regular Sterilization: Routinely sterilize pump components using boiling water methods, electric steam sterilizers, or dishwasher sanitization (top rack placement exclusively). The robust PPSU milk collector withstands repeated high-temperature sterilization without degradation.
- Complete Air Drying: Position all washed components on a clean drying rack or microfiber towel, allowing complete air circulation until all moisture evaporates before reassembly or storage.
- Charging Case Maintenance: Clean the wireless charging station using a lightly dampened cloth only. Never immerse in water or expose to excessive moisture.
- Important Safety Note: Never submerge the primary pump motor containing electronic components in any liquid. Clean the pump exterior very gently using a dampened cloth exclusively.
For accelerated, more comprehensive cleaning results, consider utilizing the Momcozy Bottle Washer system, designed to efficiently sanitize pump components.
