Small size does not mean weak suction. The P1 delivers adjustable massage and expression modes so you can gently stimulate letdown, then switch to stronger expression settings for efficient milk removal.

Everything Included

Ready to pump right out of the box, the P1 includes two shield sizes, bottles, valves, backflow protectors, and tubing for double pumping. The backflow protectors help keep milk separate from the motor for safer, easier cleaning.

Touch buttons, backlit display, and lock feature prevent accidental changes.
BPA free parts
All milk-contact parts are BPA, BPS, and phthalate free.
How to Choose the Right Pump and Fit

Picking the right pump and shield size makes pumping more comfortable and effective.

  1. Think about your lifestyle: Choose a rechargeable, portable pump if you travel, return to work, or need discreet sessions away from home.
  2. Prioritize fit: Start with the included shields, then use the Get the Right Fit program if you feel pinching, nipple rubbing, or poor milk flow.
  3. Match suction to comfort: Begin in Massage Mode to encourage letdown, then switch to Expression Mode and increase only until comfortable and productive.
  4. Consider noise level: If you need discretion at work or in public, look for pumps with quieter motors and lower decibel ratings.
  5. Plan for parts and cleaning: Choose a pump with a closed system and available replacement parts, and follow the manufacturer cleaning instructions for milk-contact pieces.
Frequently Asked Questions
What breast shield sizes come with the P1?

The P1 includes two 21mm and two 24mm breast shields. If those sizes do not fit, Cimilre offers a Get the Right Fit option to select a different size.

Is the pump safe for my milk?

Yes. The P1 uses a closed system and milk-contact parts are BPA, BPS, and phthalate free to protect your milk.

How long does the battery last?

The P1 has a rechargeable lithium-ion battery with USB-C charging. Actual runtime depends on suction settings and frequency of use, so expect to recharge regularly when pumping multiple times per day.

Are replacement parts available?

Official Cimilre replacement parts and accessories are available through Cimilre and authorized retailers for routine replacement and maintenance.
