FAQs: Natural Wave® Double Electric Breast Pump

Is the Lansinoh® Natural Wave® Double Electric Breast Pump portable? 

Yes, the Lansinoh® Natural Wave® Double Electric Breast Pump can be used with the AC adapter or using the rechargeable battery! Please be sure to charge the battery for at least 3 hours before first use and to use a charging block rated 5V-2A!

What choice of settings does the Lansinoh® Natural Wave® Double Electric Breast Pump offer?

The Lansinoh® Natural Wave® Double Electric Breast Pump was designed to mimic the baby’s natural feeding pattern and includes 12 suction levels for Stimulation, Expression (3 pumping styles) and NaturalWave modes for a tailored and effective pumping experience. The ‘Stimulation’ phase uses quick and short suction to initiate the milk flow or a "let-down", the ‘expression’ phase maximizes milk flow through longer, deeper suction and our patented NaturalWave Mode uses rapid fluttering motions at the end of each cycle with pauses in between to mimic baby’s breastfeeding tongue movements to encourage multiple let-downs per session for effective pumping and maximized milk output.

What is the benefit to the NaturalWave Mode?

Rapid fluttering motions at the end of each cycle, with pauses in between, mimic a baby’s natural breastfeeding tongue movements. This technique encourages multiple let-downs per session, promoting effective pumping and maximizing milk output. It ensures you are pumping to empty, which supports optimal milk production and helps build confidence in your pumping routine. Additionally, it improves comfort and overall pumping efficiency. NaturalWave Pumping Mode further enhances this process by increasing the number of let-downs while delivering a pumping experience that closely resembles breastfeeding.

 

How does the Memory Feature Work?

 

On pumping start, the pump automatically transitions from Stimulation Mode to Expression Mode after 2 minutes of operation. This transition occurs consistently every time the pump is turned on, regardless of previously used modes or settings. However, moms can interrupt the automatic transition and switch to a mode of their choice at any time. The pump stores previously used settings and timer details in its memory across all modes, even after being switched off or paused. Pausing the pump is as simple as tapping the power button on the screen, and it can remain in a paused state for up to one hour.

 

Are there any pumping hacks I can use with Lansinoh® Natural Wave® Double Electric Breast Pump?

 

Power Pumping helps your body produce more milk by rapidly emptying your breasts. It’s designed to complement your normal routine, not replace it, and can enhance milk supply over time. To boost milk supply, gentle vibrations mimic a baby’s tongue movements, encouraging more let-downs. For added comfort, you can switch from the Expression Phase to the NaturalWave® Phase at any time for a gentler, more natural experience. When milk flow slows or you want to ensure your breasts are fully emptied, this technique mimics a baby’s flutter-like sucking to trigger more let-downs and finish strong.

 

How do I know my flange size?

 

Proper flange sizing is key for comfort and effective pumping, and sizes vary by brand—so always measure your nipple with the provided ruler and choose a slightly smaller size. A flange that’s too small can cause rubbing, soreness, or poor milk flow, while one that’s too large pulls in too much areola. Once you find the right fit, use our organic pumping spray to reduce friction and make pumping more comfortable. 

Can the Lansinoh® Natural Wave® Double Electric Breast Pump be used with other brand bottles?

It is recommended to use the Lansinoh® breastmilk feeding and storage bottles with the Natural Wave® double electric breast pump, as they are designed to work together. Moms may also pump directly into the Breastmilk Storage Bags with any Lansinoh® pump for added convenience and to save time.

What other Lansinoh products can be used with the Natural Wave?

The Lansinoh® 3-in-1 Breast Therapy Packs can be used with the Natural Wave as pumping aids.  Simply heat them according to the instructions on the pack and wrap them around the breast flanges to encourage let-down and reduce time spent pumping.

How often should I replace the Lansinoh® Natural Wave® Double Electric Breast Pump?

Valves should be replaced every 4-6 weeks depending upon usage.  We suggest inspecting the pump and accessories for wear and tear daily.  If you notice any parts that are cracked, misshapen, or no longer connect, we recommend discarding and replacing them. 

Where can I buy replacement parts for my Lansinoh® Natural Wave® Double Electric Breast Pump?

Are the Lansinoh Natural Wave Double Electric Breast Pump and accessories dishwasher safe? 
The accessories of the Natural Wave Pump may be washed in the dishwasher, on the top rack, not the pump itself. The breast flange and bottle(s) may be cleaned on the top rack of the dishwasher or hand washed with dish soap and hot water. All other parts of the breastmilk expression set should be hand washed to prevent loss and extend their usefulness.  To clean the breast pump base, wipe with a damp cloth, using only water or mild soap.

Can I sanitize the Lansinoh® Natural Wave® Double Electric Breast Pump accessories in boiling water?

If you want to sanitize: 1. Place parts in a pot and cover with water making sure there is room for all of the parts to float freely in the pot. 2. Bring the water to a boil and allow the parts to boil for 5 minutes. 3. After boiling remove the parts from the pot with tongs and place on a clean towel to dry, covering the parts with a second clean towel. Place wash basin and bottle brush on a clean, unused dish towel or paper towel in an area protected from dirt and dust. Do not use a dish towel to rub or pat items dry because doing so may transfer germs to the items. 4. Allow the parts to dry completely before assembly and use. Partially dried parts may affect the operation of the pump. 5. Once parts are dry the can be stored in a clean plastic bin with a lid or in a clean plastic zipper bag.

Are Lansinoh® Bottles BPA-free?

Lansinoh® bottles and NaturalWave® Nipples are BPA, BPS, and phthalate free. Our bottles
are made from polypropylene. Polypropylene is considered to be the safest of all plastics, this
is a robust plastic that is heat resistant. Because of its high heat tolerance, Polypropylene is
unlikely to leach even when exposed to warm or hot water. This plastic is approved for use
with food and beverage storage. Polypropylene plastics can be re-used safely and with hot
beverages

What is the suction power of the pump?

The suction strength on our Lansinoh® Natural Wave® Breast pump varies between 80mmHg and 280mmHg, depending on the suction level selected by the mom. There is no difference in suction level when using the pump as a single or a double.

What is the difference between hospital strength and hospital grade?

Hospital strength is the term used to describe a breast pump that can reach at least 250 mmHG of suction, which is the standard for pumps used in the hospital. The Lansinoh® Natural Wave® has adjustable hospital strength suction that meets this 250mmHG required range.

The meaning of the term hospital grade depends on who is using the term. Healthcare providers such as nurses and lactation consultants that work in hospitals use hospital grade to describe a pump that has been clinically validated to establish and maintain a breastmilk supply. These pumps are used with patients who need to pump breastmilk for their sick or preterm babies. They are designed to be very durable, so they may be used for several years by a large number of patients. These pumps are usually not sold in stores or available through insurance. They are typically larger and bulkier than personal pumps, and they can cost thousands of dollars.

You may see some personal pump brands describe their pumps as “hospital grade”. However, these pumps have not been clinically validated and are generally only considered appropriate for single-user, personal pumping.
