For optimal output, replace every 90 days (or when you notice discomfort or signs of wear).
Yes, you can. Simply pay for your breast pump and accessories using your FSA/HSA debit card at checkout, or pay with another credit card and submit your receipt to your plan administrator for reimbursement.
The right size is key for maximizing comfort and output. Willow offers flanges and containers in size 21mm, 24mm, and 27mm. If you measure smaller than 21mm, we offer Sizing Inserts in sizes 15mm, 17mm, 19mm that snap into our 24mm Flanges and Containers. We strongly recommend measuring yourself to determine your Willow size as it might be different from other pumps you’ve used. Unsure of your size? Visit our sizing guide or check out our exhaustive guide on how to measure your flange size which includes pro tips from Willow’s lactation consultants.
After every use, you can wash by hand or pop the parts in the dishwasher, top rack only.
It’s important to wash breast pumping parts after every session to avoid the growth of bacteria. We also suggest you do not store your Container in the fridge or the freezer. This can lead to decreased performance for the Container.
