FAQs
Why is the eufy Wearable Pump S1 better than other pumps?
The eufy Wearable Pump S1 features industry-first HeatFlow™ technology for improved milk flow and comfort, hospital-grade suction, and OptiRhythm™ smart customization.
Why heating, and is it safe to use?
Heating increases milk output and comfort. Our embedded HeatFlow™ system uses a precision sensor that checks every 3 seconds to maintain optimal heat (95–105°F). You get 7 heat levels, a 5–15 minute auto-shutoff timer, and all parts are BPA-free silicone. The heating flange has passed 56 hours of continuous boil and 1,000 flex tests.
What are the warranty and return policies?
• 12-month warranty on the pump hub
• 3-month warranty on all washable components
Returns accepted only if unused, unopened, and in original packaging.
What accessories are included, and are replacement parts available?
• 2 pumps with 24 mm flanges

• 1 storage bag, 2 dust covers, cleaning brush, and user guide
Replacement parts for all washable pieces are sold separately.
Do wearable breast pumps decrease milk supply?
No—when used correctly, the S1 can maintain or even boost supply. Its ultra-quiet motor, adjustable suction, and heating feature mimic natural nursing patterns and help stimulate let-down.

Can I really get a Free Breast Pump, no catch?
Yes. The Affordable Care Act (ACA) includes provisions requiring insurances to cover a breast pump. However, getting yours free will depend on your specific insurance. This is where we help. We work with your insurance directly to determine your exact coverage. From there, we provide you with your options and ship it out free of charge.
Which pump can I get?
As you can see under Breast Pumps, we carry all the top brands and models. However, your Free Options are dictated by your insurance and specific coverage. Each insurance has it’s own policies that determine which breast pumps are covered in full.
Have a specific pump you want that’s not covered 100%?
We’ll use your benefits to reduce the cost, so all you have to do is pay a reduced “Upgrade” fee.
Please reach out if you have any questions, we’d love to help you walk through your options!
