Spectra S2 vs Medela Pump In Style: Feature Comparison

Every breast pump has some unique features and accessories. Let’s take a look at some similarities and differences between the Spectra S2 and the Medela Pump in Style.

Single vs. Double Pump

Double pumping can be a lifesaving feature, especially if you have twins or when you want to pump a lot of milk in the shortest time. Also, double pumping is convenient and time efficient for working or busy moms.

For instance, expressing milk from one breast takes up to fifteen minutes. With a single pump, the session can last up to 30 minutes, and a double pump saves you 15 minutes. It also helps in milk stimulation, thereby boosting your milk supply.

On the other hand, if you have time on a lazy afternoon or evening, you can use the single pump.

WINNER: TIE — Both Medela and Spectra s2 can be used as single or double pumps meaning you can express milk from both breasts concurrently.


As the name suggests, a hands-free breast pump fits conveniently in the nursing bra while leaving your hands free to do other tasks. Hence, you can pump milk while you catch up with the latest from your smartphone.

This is the best option for working moms since they can express milk in the comfort of their workstations and meet work targets without taking some time off. Even better, they can pump milk while driving as their hands steer the wheel.

WINNER: TIE — The Medela and Spectra S2 are both hands-free and performed very well during testing.

Closed Vs. Open System

The difference between a closed and open system boils down to the cleaning process. Whether it’s a new or used purchase, it’s vital to gather information about whether the pump is open or closed.

A closed system is fitted with a filter that acts as a blockage between the pump and the collection kit. Thus, the milk doesn’t go to other parts of the pump. This feature ensures maximum cleanliness. In addition, it prevents contamination of milk by harmful elements such as bacteria, mold, and viruses. Contrary, an open system doesn’t have such a feature. Therefore, a closed system is a hygienic option for parents.

In our review, Spectra S2 has a closed system that blocks milk from entering the tube. Therefore, you don’t have to clean the tubes all the time after every expression. As a result, Spectra S2 requires low maintenance since it features a closed system.

Medela has an open system meaning the milk can easily flow back to the tubes. To operate an open system, you’ll have to let the machine run and allow the excess milk to clear after you’re done. Such a pump requires high maintenance, and it’s crucial to thoroughly sterilize and aerate the parts to minimize the risk of mold formation.

WINNER: Spectra S2 — Spectra S2 seems very safe and hygienic with its closed system compared to Medela Pump in Style.

Battery Adapter

A battery adapter is an essential feature when shopping for an electric pump. It offers the convenience of pumping anywhere and anytime. For instance, if you plan to travel on a long journey, this becomes crucial since you can still pump milk while on the go.

Medela breast pump comes with a battery adapter, and hence you can pump milk even when walking, driving, or relaxing on the beach. Spectra doesn’t have this privilege, and you can only express where there’s a guaranteed electricity supply.

However, an adapter does increase the weight of a pump. For this reason, the Medela pump is a little heavier than the Spectra S2 pump. If you’re looking for a lightweight pump, then you’d have to compromise on the luxury of pumping milk on the go.

WINNER: Medela Pump in Style — Yes, Medela Pump in Style comes with a battery adapter, but the feature makes it a little heavier to carry. 


Pumping milk is a discreet affair, and most mums will want the process to be quiet so that it doesn’t disturb those around. Whereas when pumping at home, you can do it privately in your room, the same can get complicated for working moms in the office. Additionally, if you’re outside in a public place, you’d mind the noise.

While testing, we found Spectra S2 is a quiet pump that makes it ideal for use even at night because it doesn’t wake people around you when you use it. Furthermore, you’re less likely to wake your sleeping angel when they are sleeping.

Medela is noisy and can be uncomfortable to use in a public place with many people. Besides, it’s not a favorable choice at work and can make heads turn.

WINNER: Spectra S2 — Spectra S2 performed better on quietness in our testing than the Medela pump in style.

Milk Stimulation

Let’s face it! Breast pumps mimic the natural suckling of a baby, which stimulates milk production and flow.

Spectra S2 is a hospital-grade electric pump and promises a remarkable performance. It has great suction, and its pumping power will enhance your milk production.

When it comes to design, Spectra S2 has suction that stimulates milk letdown in a systematic process. It is vital when you have less flow and you need to ensure a constant milk supply for your baby.

The process starts with massaging the breast gently and ends at expression. Speed is essential here to allow for a smooth process. Thankfully, with Spectra S2, you can adjust the speed by starting slowly to stimulate the milk and increase the speed when the production has picked momentum. Notably, the speed will increase only when you’re comfortable with the suction. Therefore, it’s a flexible choice for most moms.

On the other hand, the Medela breast pump features a knob that is not flexible. Hence, it’s not possible to adjust the speed and vacuum at the same time.

WINNER: Spectra S2 Spectra S2 has soothing pumping like a baby suckling that makes it a comfortable option. Medela is noisy and has minimal pump speed options.


Spectra s2 is a beautifully designed breast pump that comes as a full package of what you need to pump milk comfortably and store it in a refrigerator or freezer. It’s a value pack that contains everything to get you started.

Medela has high-quality bottles that don’t lose traction even after boiling or sterilizing. You might not be impressed by the quality of Spectra’s bottles since they have a thin thread. What this means is that flanges are likely to come off when you’re pumping. Also, the bottles and nipples lose their sturdiness when sterilized in hot water.

Spectra’s valve sticks to the pump, and removing it can be an uphill task. Due to this, its quality may deteriorate fast and wear out. For Medela, there’s a membrane attachment that allows for an easy pull, and this will endure wear.

Spectra breast pump comes with a breast shield and flange as a single item, which makes the clean-up difficult. Luckily, this problem can be solved by purchasing Spectra-Medela adapters that allow users to fit in Medela flanges alongside the Spectra pump. Therefore you can enjoy the premium quality of Medela’s accessories.

WINNER: Medela Pump in Style — Medela Pump in Style comes with more accessories than Spectra.

Spectra S2 vs Medela Pump In Style: What’s The Difference?

There are some key differences between Spectra S2 and the Medela Pump in Style.

The first major difference is the system. The Spectra S2 has a closed system design, whereas the Medela Pump in Style has an open system design. Since the Medela pump in style comes with a rechargeable battery and some extra accessories, it costs a little more than the Spectra S2.

For a pumping, working mom, these extra features of Medela Pump in Style might be very helpful. So if you don’t want to spend some extra bucks and don’t need the portability, then Spectra S2 is the best choice.

Which One Is Right For You?

Spectra S2 has a unique tube that prevents the backflow of milk as you express it. There’s no chance of contamination. Moreover, it has been made thoughtfully, giving no chance for air to come between the milk and the pump. With this in place, no bacteria can get into your baby’s drink.

As per our observation, the closed system of spectra s2 is a plus since it’s both hygienic and convenient. Nurses highly recommend it for its indisputable motherly care that is much needed when nursing your little bundle of joy.

Accordingly, its lightweight design makes it easier to carry around, and you can pump the milk anytime and anywhere, making it convenient for working mothers.

Although suction is essential in stimulating milk flow and boosting the pumping power, not all users would be comfortable with the Medela pump system. Some reviewers expressed the opinion that their nipples became prone to sensitivity with continuous use.

However, paying attention is vital when positioning the flange to the nipple. For Spectra, the feeling is fluttering and feels like a real baby. You’ll feel comfortable using this pump, which is necessary for milk production.

Medela Pump has been a renowned brand for many years and is trusted by mothers worldwide. With high technology, the pump can express milk maximum quickly. It is portable, meaning you can easily carry it wherever you go. The motor has a unique design that doesn’t allow milk into it, making it easier to clean.

On health issues, we feel the Medela brand needs to address this issue in their future pumps since open systems promote the growth of mold and bacteria.
