  • What does the “BPA and BPS Free” Icon on your packaging mean?

    The chemical bisphenol-A (BPA) is widely known to be a hormone disrupter. Acting like an estrogen imposter, BPA has been linked to cancer, type 2 diabetes, depression, heart disease and a number of other ailments. BPA can be especially dangerous in pregnancy, infancy and childhood – so much so that many governments around the world have banned BPA in the production of baby bottles (as well as other products).

    The chemical bisphenol-S (BPS) is used as a plasticizer by some manufacturers and, in many cases, has been used to replace BPA. BPS is also a hormone disrupter, but is currently allowed for the production of baby bottles and similar products.

    Because safety is a top priority for Lansinoh, we have taken proactive measures to ensure our Lansinoh® mOmma® bottles with NaturalWave® Nipples are BPA and BPS free. 

    Additionally, all our products that may come in contact with breastmilk are BPA and BPS free, as well as our mOmma® toddler line. This includes:

    • Lansinoh® HPA® Lanolin
    • Lansinoh® Clean & Condition Baby wipes

    Is Lansinoh® Signature ProTM Double Electric Breast Pump BPA and BPS Free?

    Yes! Because safety is a top priority for Lansinoh, we have taken proactive measures to ensure Lansinoh® Signature ProTM Double Electric Breast Pump is both BPA and BPS Free.

    How do Lansinoh® Double Electric Breast Pumps compare to others available in retail outlets?

    The Signature Pro™ and Affinity Pro™ are the only pumps with three customizable pumping rhythms to maximize your milk production and comfort. They are both designed as closed systems; milk will not back up into the tubing or into the motor so you will not risk losing milk and so your breastmilk is safe for your baby. The closed system prevents airborne contaminants, bacteria and mold growth that can result from moisture in the tubing or pump base. 

    Can I pump directly into the Lansinoh® Breastmilk Storage Bags?

    Because Lansinoh® Breastmilk Storage Bags have a double zipper closure, they will not fit securely on the pump so you cannot pump directly into them.  

    Do you have a car adapter to power the pump?

    The Signature Pro™ and Affinity® Pro Double Electric Breast Pumps do not include a car adaptor. They are powered with the AC adaptor (included) or six AA batteries (not included).

    Can I use the current AC adapter internationally?

    The AC adaptor that comes with the Lansinoh® Signature Pro™ and Affinity® Pro Double Electric Breast Pumps can be operated in either 110-125 or 220-240 voltage.  You need to get an appropriate plug adapter to change the actual plug to fit the international outlet.  

    How long will the pump work with batteries?

    Lansinoh® Signature Pro/Affinity Pro Double Electric Breast Pumps will run for approximately two hours with six AA alkaline batteries.

    Can I use batteries with the Lansinoh® Signature Pro™ Double Electric Breast Pump?

    The Signature Pro™ Double Electric Breast Pump can work with either the AC Adaptor (included) or with six AA batteries (not included).  We recommend using alkaline batteries only and not rechargeable batteries.  Do not mix old and new batteries; replace as a simultaneous set.  If batteries are in the pump, but your AC adaptor is in use, the pump will use the AC adaptor to power the pump.  For the most economical use, we recommend using the pump with the AC adaptor that has been provided with the pump.  

    Do you sell accessories for the pump such as extra parts, cooler bag, freezer pack, and carry bag?

    You can order extra parts for our pumps including a cooler, re-usable freezer pack and carry bag online at our website,

    Can I use other pump brand replacement parts with the Lansinoh® Double Electric Breast Pumps?

    We do not recommend using another pump’s replacement parts (including the first generation Lansinoh® Double Electric Pump) with the Lansinoh® Signature Pro™, Affinity® Pro, or Affinity® Double Electric Breast Pump as these components were made specifically for each individual Lansinoh pump. Using other brand pump parts with the Lansinoh pump will void your warranty.

    Can I use a microwave steam bag to clean and sterilize the pump parts? Are pump parts dishwasher safe?

    *Please Note: Tubing and tubing Y connector or white pump connector should never be washed or sterilized*

    All parts, except tubing and tubing Y connector or white pump connector and breast flanges, can be steam-sterilized in a microwave bag according to the manufacturer’s directions. All parts, excluding the tubing, y connector and pump connector are dishwasher safe. However, we highly recommend gently hand washing for the white valves. They are delicate and can affect the performance of the pump if damaged or torn through vigorous washing or harsh detergents.

    Please be sure to use the appropriate amount of water according to the directions on your steam sterilizer to ensure that parts do not get overheated and/or melt. Also, all pump parts must be completely dry prior to use or performance may be affected. 

    What do the 1 leaf, 2 leaves and 3 leaves on the Mode setting mean?

    There are three different pumping rhythms you can choose from to maximize comfort and breastmilk extraction efficiency. These different rhythms are denoted by one, two and three leaves on the circular mode button.  Every mom is different, so we recommend that you try each of the pumping rhythm modes to determine which one works best and is most comfortable for you.

    What is the ideal setting for maximum milk flow using the Lansinoh® Signature Pro™ Double Electric Breast Pump?

    Since every woman is different and each mom responds differently to breast pumps, there is no ideal setting that works for everyone. We encourage you to try different pumping rhythms and use the + and – buttons to find the most comfortable setting for you.  

    What is the suction range of the Lansinoh® Signature Pro™ Double Electric Breast Pump?

    The Lansinoh® Signature Pro™ Double Electric Breast Pump ranges from 55-140 mmHG in the stimulation mode and 80-220 mmHG in the expression mode. There are eight suction settings. 

    How many times does the Lansinoh® Signature Pro™ Double Electric Breast Pump cycle?

    The Lansinoh® Signature Pro™ Double Electric Breast Pump cycles 87-125 times/minute in the Stimulation phase and 37-95 times/minute in the Expression phase.

    What cycle and suction settings will the pump go to once the let-down phase has ended after two minutes?

    Once the pump has switched from the let-down/stimulation phase to the expression phase, the pump will be at the following settings:

    • Pumping Rhythm: 2 leaves 
    • Suction setting: level 3
    • You can change the between the three pumping rhythms by pushing the Cycle Mode Toggle Button with the three leaves.
    • You can adjust to your suction level by pushing the + button to increase suction or pushing the – button to decrease the suction.

    Can I switch from let-down to expression before the two minute cycle is finished?

    If you achieve let-down prior to the two minute automatic switchover, you can push the stimulation/expression toggle button and you will go into the expression phase. If you wish to return to the faster let-down/stimulation phase during a pumping session to bring about another let-down, you can switch back into the let-down/stimulation phase by pushing the stimulation/expression toggle button again.  

    Why do you have a special purple rim on your breast flanges?

    In order to make a mom’s pumping experience as comfortable and efficient as possible, we added special soft outer rims to the ComfortFit™ breast flanges. This also ensures that you have a good seal, which aids in the suction.
