Spectra S2 vs Spectra S1

Why Choose a Spectra Pump?

Spectra has some of the best breast pumps on the market, mostly due to the fact that their products focus on Natural Nursing Technology. 

These features help make breast pumping more comfortable and feel more natural.

No mother wants to feel like they are being milked by a machine. You are actually not as efficient if your breast pump doesn’t mimic the natural patterns of a nursing baby. 

This is where Spectra excels.

With customizable settings, you can work through all the phases of breastfeeding, from suckling and pre-letdown all the way through post-letdown. 

You also have full control over the power and speed of suction, so you can always find a setting that is most comfortable for you.

You can tell that a lot of thought went into the design of Spectra’s products. They build them to last, equipping them with a closed system and a powerful motor that is quieter than most other breast pumps.

Spectra S1 Review

Spectra S1

There is no denying that the S1 breast pump is Spectra’s most highly rated product. It is most praised for its efficiency and portability.

This hospital grade pump allows you to pump one or both breasts at the same time, increasing your efficiency per pumping session. 

This can really be a lifesaver when you only have a short break at work to pump.

While the rechargeable battery does help with portability, the overall size of this pump can make transporting it a bit tricky. 

There are some breast pump bags that can fit this pump, but it will still be tight with the other items you will need for storing and transporting your breast milk.

You also have fully customizable settings on the pump motor, with 2 phase suction and 12 levels of adjustable suction. The pump also remembers your last settings so you don’t have to restart at your next pumping session.

The best feature of the S1 breast pump is its built-in rechargeable battery. This single feature sets it apart, making it more portable than most other pumps that require access to electricity in order to pump.

With your Spectra S1 breast pump, you get everything you need to start your pumping journey: 

  • Pump motor with built-in rechargeable battery
  • A pair of breast flanges
  • Duckbill valves
  • Two bottles with nipples and sealing discs
  • A pair of backflow protectors
  • Two sets of tubing
  • An AC power adapter

Additional parts are available for purchase, which will be a necessity over time. The duckbill valves have a tendency to wear out over time and not stay attached while pumping. 

You may want to start out with an extra supply as backup for whenever you may need them.

Pros

  • Equipped with an inbuilt rechargeable battery
  • Hospital grade double/single pump with quiet motor
  • Customizable settings with 2 phase cycling and adjustable suction
  • Closed system with Spectra backflow protector keeps motor and tubing clean and dry
  • Includes a timer to track pumping duration

Cons

  • Tubing and duckbill valves can stretch out and fall off while pumping
  • Only comes with two flange sizes and are expensive to purchase separately
  • Needs an adapter to pump into bottles other than Spectra brand
  • More expensive than the S2

Spectra S2 Review

Spectra S2

The Spectra S2 pump has all of the same features included with the S1 pump except for the rechargeable battery.

You still get the same level of efficiency with the hospital grade motor and the ability to pump one or both breasts at the same time. 

You also have all of the customizable settings that will help make your breast pumping session more comfortable and productive.

Just like with the S1, the S2 features a closed system with the Spectra backflow protector to keep the tubing and motor clean and dry. 

No need to worry about moisture buildup and bacteria growth with this protective feature.

In addition to the pump itself, your purchase comes with everything you need to start pumping. All of the tubing and pump attachments, as well as two bottles to catch milk and feed your baby, are included in the box.

Depending on your breast size, you may need to look into the other breast flange sizes available from Spectra. The pump itself only comes with the standard size, which may not be right for you. 

If you find that your pumping sessions are uncomfortable or just not as efficient as they should be, try changing flange sizes.

It may seem like this pump is just slightly subpar compared to the S1 because it does not have the rechargeable battery. 

However, to make up for this, the price is a little bit less for this pump, making it a great choice for mothers who are trying to watch their budget.

Pros

  • Hospital grade double/single pump with a quiet motor
  • Includes a timer to track pumping duration
  • Customizable settings with 2 phase cycling and adjustable suction
  • All parts are BPA/DEHP free
  • Closed system with Spectra backflow protector keeps motor and tubing clean and dry

Cons

  • Only pumps into Spectra bottles if you don’t have an adapter
  • Duckbill valve has a tendency to fall off while pumping
  • There is no option to use this pump with batteries
  • Only comes with two flange sizes and are expensive to buy separately

Common Features & Performance

Both of these pumps share a lot of the same features. Let’s take a look at these in more detail.

Closed System

When it comes to breast pumps, there are two types of systems that are used: open and closed.

Choosing one over the over can make a very big difference when it comes to the cleanliness of your pump.

Closed systems are preferred. These pumps are made with special barriers and filters that prevent milk from entering the tubing and motor. 

Extra moisture ending up where it’s not supposed to be may not only damage the motor, but it can also lead to bacteria growth which may end up in your pumped milk. 

Having a breast pump with a closed system can keep your baby healthy and cut down on the hassle of cleaning those tiny and hard to reach places.

Both the Spectra S1 and S2 pumps have closed systems, which is a big reason so many mothers and professionals recommend these breast pumps.

Hospital Grade

“Hospital grade” is a term that has a somewhat loose meaning. There is nothing in particular that classifies a breast pump as hospital grade other than the fact that it is the strongest you can get in terms of suction.

It can also refer to the ability to use the same between more than one person, but this has more to do with the closed system rather than the “hospital grade” label itself.

That being said, the Spectra S1 and S2 breast pumps are described as hospital grade, which means you won’t find many others with the same amount of suction power these offer.

Customizable Settings

With so many modes available on both the Spectra S1 and S2 breast pumps, you have full control every stage of your pumping session. 

There are 12 different levels of suction, pre-letdown, let-down, and massage settings.

Another great feature of these pumps is their ability to remember your settings for the next time you pump. Pick up right where you left off without needing to remember all of the fine tuning you did at the last session.

Built-In Features

Both the Spectra S1 and S2 have some nice built-in features that make your pumping session a little bit easier.

First, there is a built-in timer. This will help you keep track of your sessions without needing to remember to set one or looking at the clock to track your time.

Pumping at night is also easier with these pumps. The motor is one of the quietest on the market. No need to worry about waking your spouse or little one even when you are pumping right next to them. 

The built-in nightlight will give you enough light without waking yourself or anyone else up by turning on the overhead light.

BPA Free

Some plastics should be avoided when it comes to food storage, especially when it comes to the breast milk you will be feeding your baby. Bottles made with BPA – a chemical used to harden plastics – may put your little one at risk for issues with their endocrine system. 

However, more tests need to be done to determine how harmful BPA is for children.

Until then, it is just better to play it safe and avoid plastics that have BPA. Thankfully, all of the plastic parts included with both the Spectra S1 and S2 breast pumps – including the tubing, flanges, and capture bottles – are BPA free to keep your baby’s milk safe.

Differences between S1 and S2

With all of the similarities between these two pumps, there is really only one feature per pump that distinguishes one from the other. For the S1, it’s the battery; for the S2, it’s the price.

Why Choose the S1?

The biggest difference with the Spectra S1 is the fact that it comes with a rechargeable battery. This can be quite a game changer for the mother who needs to pump on the go. 

Not always needing access to electricity means that the S1 is more portable than the S2. 

You just need to make sure the battery is charged before you leave the house and you can get roughly 3 hours of continuous pumping power before it needs to be charged again.

Why Choose the S2?

Without a rechargeable battery, some may ask why they should consider the Spectra S2 over the S1.

However, the lower price point for the Spectra S2 could make this one the better choice for the budget conscious shopper.

On a new pump, you will save about $50 with the S2. It may not seem like much at first, but considering how many diapers that money can buy your little one, it can really make a big difference.

Final Word

Spectra breast pumps are amongst the best available on the market, particularly the S1 and S2 models. Both pumps are quiet, efficient, and overall very comfortable. 

You can really tell they put a lot of thought into the design of these pumps, right down to the little features, like the built-in nightlight and timer with automatic shut-off.

You really can’t go wrong with either pump. Choosing one over the other is merely a decision of portability over cost. Which will you choose?
