Choose a calendar service, then confirm the event. Downloading an .ics file does not add it until you open or import it.

Read before relying

Context matters.

  • CDC says to inspect the pump kit before use and replace moldy tubing immediately; clean milk-contact parts after every use.
  • Reduced suction, damaged silicone, poor seals, cracks or persistent contamination can require replacement before the calendar date.
  • For any brand other than the selected Spectra schedule, choose the custom option and use that pump's current manual.

Questions answered

What to know before using the result.

Can I use the Spectra schedule for another pump brand?

No. Select the custom option and enter the current manual interval for any other brand or model.

What overrides the replacement date?

Reduced suction, damaged or warped parts, poor seals and contamination can require earlier replacement. CDC says moldy tubing should be discarded immediately.

Does replacing parts replace cleaning them?

No. CDC recommends cleaning milk-contact parts after every use and inspecting the assembled kit before pumping.
