How many parts does PureLatch have, and how do I clean them?
How many parts does PureLatch have, and how do I clean them?
Each side breaks down into just a flange, a cup, and the motor. Rinse the flange and cup in warm, soapy water after every session and let them air-dry fully before your next pump.
Can people around me hear it running?
Can people around me hear it running?
The motor runs at a low hum built to stay in the background during meetings, calls, or naptime. Most people close by won't clock that it's running unless they're listening for it.
How is PureLatch different from my old plug-in pump?
How is PureLatch different from my old plug-in pump?
A plug-in pump tethers you to an outlet with tubes and a bulky motor sitting on a table. PureLatch tucks into your bra and runs on battery power, so you can keep pumping while you move around instead of sitting still.
How often will I need to replace parts like the flange or cup?
How often will I need to replace parts like the flange or cup?
There's no fixed replacement schedule. Check the flange and cup regularly and swap them in once the silicone feels stretched or the seal isn't holding as snug as it used to.
