Spectra S1 vs S2 Breast Pump Comparison & Review

What factors should you consider in choosing a breast pump?

Purchasing a breast pump – particularly if you intend on solely pumping – is a significant financial and emotional commitment that may be nerve-wracking. Despite the fact that you will be spending two hours a day connected up to your pump, you will frequently have to purchase it without first testing it out or seeing it in person.

After receiving my last pump via insurance, I spent the better part of two hours looking at the website, attempting to figure out which one I should purchase.

The easiest approach to decide which pump you want is to think about which characteristics are most essential to you and prioritize them. Examples include the following:

  • The ability to move about (whether or not an electric outlet is required, size)
  • Being able to pump while on the phone, for example, is a source of distraction.
  • The ease with which something may be used (features like timers, settings)
  • Price

Let’s talk about the different features that the S1 and S2 have.

Who Should Buy This Pump?

A top-quality breast pump with great pumping power and a long lifespan will be of interest to moms who are searching for something that will endure for a long time. It is more costly than other pumps, but if your medical insurance is willing to cover the cost, we recommend that you go ahead and get it.

A powerful, silent machine that has been engineered to endure. With the help of this pump, mothers will have another weapon in the battle to effectively breastfeed their children.

Spectra S1 and Spectra S2- Similarities

Let me let you in on a little secret about these very popular Spectra pumps: they are virtually similar to one another. There are just two significant changes between the S1 and S2: the pricing and the battery. As a result of the rechargeable battery included in the S1, the S1 will cost you more money than the S2. That’s all there is to it, the battery and the pricing are the only things that vary! Let’s take a look at some of the characteristics that both pumps share.

Closed system

The S1 and S2 breast pumps are both closed system devices. The milk does not really enter the pump as a result of this arrangement. This helps to prevent mold and germs from growing on the pump (and on all of that fresh milk!). When your milk is produced in a closed system, there is almost little chance of it being contaminated.

Additionally, the Spectra pumps have a high resale value as a result of this. Many individuals will purchase a used closed pump system, while purchasing a used open pump system is not recommended in most cases. It is possible that you may be able to sell your Spectra once your personal pumping adventure has come to an end, because to its extended lifespan and high power.

Hospital Grade

Breast pumps used in hospitals are widely acknowledged to perform about ten times better than the typical breast pump available for purchase by the general population. These Spectra pumps are distinguished by the fact that they are both of hospital-grade construction, which is uncommon. While this is an unregulated word that anybody may use to describe their pump, it usually indicates that the pump is the most powerful you can purchase and that it can be used by a large number of people at the same time (as long as everyone has their own accessory kit). The Spectra is the finest you can get unless you want to rent a pump from your local hospital.

Spectra S1 Pump Review

It is true that the Spectra S1 Electric Breast Pump was released before the S2, however it does not imply that it is an out of date model.

As a matter of fact, many parents continue to use and like the S1 because of its simplicity and comfort.

It is lightweight, weighing just three pounds, and has a rechargeable battery as well as a convenient carrying handle. Because of this, you can even move about your home or stand up and stretch while pumping without having to worry about a plug coming out of a wall-mounted socket.

Spectra - S1 Plus Electric Breast Milk Pump for Baby Feeding

Aside from the breast pump itself, it comes with two different sizes of breast flanges, two wide neck bottles for pumping into as well as locking rings and caps, valves, back milk flow guards, tubing, and a power supply and adapter in case you want to receive your power from a different source.

But, to go back a little farther, the backflow protector is important in any effective breast pump since it helps to avoid a buildup of breast milk in the tubing, which is difficult to clean up and may lead to mold growth over time. In addition to having an easy-to-read and comprehend control panel on the top, it also includes a nightlight that you can switch on to operate it while pumping in the dark, which is particularly helpful for late-night pumping.

  • The disadvantages of the Spectra S1
  • It is somewhat more costly than the Spectra S2 and, as a result, may seem to be a little out of reach for some parents.
  • When you initially buy the pump, the first charge may take a long time and may even need more than one night to get a complete charge of the pump.

Spectra S2 Breast Pump Review

It does not make the Spectra S2 Electric Breast Pump any less essential or well-liked by mothers all around the world just because it was released later than the S1.

In fact, this Spectra breast pump weighs just two and a half pounds, making it much lighter than the S1.

It includes the same features as the S1, including a night light for seeing the display in the dark in the middle of the night and an auto timer that turns off the device after 30 minutes of inactivity. Because it does not have a rechargeable battery, this is not intended to extend the battery’s life, but rather to make pumping more comfortable for the user.

Even though it has a backflow prevention device, the tubes are also intended to work with a closed system pump. Th

Features of the Spectra S2

  • Life of the battery: Because this Spectra pump comes with a power cable and converter (including a vehicle adaptor), it does not come with a built-in battery or the ability to accept disposable aa batteries of your own.
  • Pump accessories include two wide neck bottles, flanges, tubing, a backflow protector, and a power cable. The pump may be purchased separately.

  • After many months of continuous usage, the suction power may begin to seem as though it is losing its effectiveness.
  • In reality, while using the pump as a dual pump, as it was intended to be used, the suction does not feel as powerful on both breasts as it does on one breast.

Why Choose a Spectra Breast Pump?

Spectra manufactures some of the finest double electric breast pumps available on the market, which is mostly owing to the fact that their products are centered on Natural Nursing Technology for women. These characteristics contribute to making double pumping breast milk more pleasant and natural to accomplish. No mother likes to feel as if she is being milked by a machine, and this is especially true for new mothers. If your breast pump does not match the normal rhythms of a nursing infant, you will actually be less efficient in your breastfeeding.

Spectra breast pumps are very effective in this situation.

Working through all stages of breastfeeding with adjustable settings is possible, from suckling milk and pre-letdown with massage mode, through post-letdown with massage mode and all in between!

As well as the suction strength and the pace, you have complete control over the device, allowing you to select the setting that is most comfortable for you at any time.

With Spectra’s goods, you can tell that a lot of thought has gone into their development. They are built to endure, and they are equipped with a strong motor that is much quieter than most other breast pumps.

Spectra S1 vs S2: What Do They Have in Common?

The Spectra S1 and Spectra S2 breast pumps perform the same tasks and, as a result, are quite identical in most respects, with the exception of three or four changes that we shall discuss in more detail later.

Closed Pump

Both Spectras are equipped with a closed pump system. To prevent milk from entering the pump’s motor from entering via the tubing, a closed pump is attached for back-flow prevention. Contamination is thus less likely to occur. In other words, since there is no touch between the milk and the machine, it is unlikely that germs would develop in the pump.

Pump Settings

The pump settings are yet another important element that both the S1 and S2 have to provide. Being able to change the settings implies that you have the ability to regulate and alter the pace at which the milk flows. Controlling the flow rate is critical since the milk flows more quickly at some stages of the process than at others, depending on the stage and the session. Both kinds of suction offer a total of twelve distinct suction settings to choose from.


The S1 and S2 are both equipped with motors that can produce pressures of up to 250 mmHg. This section pace is quite fast, which allows you to do the task in a shorter amount of time. If you need to pump, you will be able to do so in full solitude since the S1 and S2 are both very quiet and will not produce any noises that would attract attention to what you are doing or cause your baby to awaken due to the loudness if you use them together.


When it comes to accessories, both pumps come with bottles, valves, and flanges as standard equipment. You may purchase extra accessories, such as a breast pump bag to store your pump components, if you so wish. These will be charged separately.

Is Spectra S1 worth the upgrade?

I won’t be pumping far enough away from home to make the additional $95.00 worthwhile. I believe the s1 is more convenient for moms who travel often or who work away from home.

Is Spectra or Medela better?

Spectra vs Medela: the bottom line

I would suggest the Spectra over the Medela without hesitation. Having tried both (as well as a number of other pumps), I would recommend the Spectra if you have a choice.

Does insurance cover spectra S1?

This is an Insurance Upgrade Option, which contains convenience items and/or features that are not covered in full by the insurance policy. Insurance will only pay for goods that are medically required for pumping; thus, extra costs will be incurred, which will be the responsibility of the patient.


Breast pumps from Spectra, especially the S1 and S2 versions, are among the finest available on the market, and they are highly effective. Both pumps are quiet, efficient, and, thanks to the employment of massage and expressiveness modes, they are very pleasant.

They put a lot of care into the design of these pumps, even down to the smallest details like the built-in night light and timer with automatic shut-off, which truly stand out.

As you can see, there are only minor changes between the Spectra S1 and S2 breast pumps that may render one totally inappropriate for a nursing mother. The two issues of whether you need a built-in battery or not, as well as whether you require the less expensive S2 model, resurface once again in our discussion.
