<< Buy Spectra S1 Electric Breast Pump>>


Spectra Baby USA S1 Hospital Grade Electric Breast Pump or simply Spectra S1 is another of my favorite double breast electric pump and #2 Double Electric Breast Pump on our list. Spectra S1 gives a tough challenge to Medela Pump In Style Advanced Breast pump. In our Spectra Baby USA S1 Hospital Grade Electric Breast Pump review, Spectra S1 scores well on features such as design, LED display for various settings, night light, good suction, hygiene and almost silent operation. I used it for 3 months. Spectra S1 could do a lot better if they can address issues such as lack of service, shoddy manual, cheap material and perhaps a poor battery life. It’s tough to get parts of right sizes like flanges and shields. Spectra S1 is not hospital grade even though its a closed system pump. Hospital grade actually means that the pump can be used by multiple people. If Spectra S1 manufacturer wants to imply its Hospital Grade in respect to its efficiency, then yes, Spectra S1 excels! Spectra Baby USA S1 Hospital Grade Electric Breast Pump is the cutest pump in the market and super effective. I wouldn’t hesitate to RECOMMEND it.

Spectra Baby USA S1 Electric Breast Pump Review

Spectra Baby USA S1 Hospital Grade Electric Breast Pump is an advanced, super-efficient and quiet electric breast pump.

Spectra breast pump has got the cutest looks also of all the double electric breast pumps. Spectra S1 weighs 3.3 pounds and product Dimensions are 7.9 x 7.9 x 6.7 inches.

Spectra S1 has both power source (power adapter provided in box) and rechargeable battery option (batteries are not provided).

Spectra breast pump is nicely designed with LED display and night display. The LED display shows the pumping time, mode and the suction speed.

Here is a point wise breakdown of Spectra baby USA S1 hospital grade double electric breast pump.

    1. Ease of Use: Spectra S1 is very easy to use. I didn’t have to read the manual to figure out its working.

    ​2. Efficiency: Spectra breast pump is super-efficient. Of all the breast pumps that I have used or seen in action, this one has the best suction which means more milk.

    Spectra S1 has suction of 300 mm Hg which means a powerful suction at its maximum.

    Perhaps this is the reason why the manufacturers claim its Hospital grade. While using it, I found it to be almost as good or even slightly better than Medela In Style Advanced.

    Many moms have mailed me and told me that they also love spectra S1 because of its ability to build and establish a mother's milk supply. 

    Spectra S1 could be an alternative to Medela’s when a mom has to build up her supply of breast milk without breaking a bank.

    3. Portability: Spectra S1 is small and portable but loses out to Medela Instyle Advanced range due to lack of a backpack or a Tote.

    Still, its lot compact then other breast pumps. It takes a lot less space. It weighs in at 3.3 pounds.

    4. Comfort: Spectra breast pump (Spectra S1) is so comfortable that breast pumping was no longer an ordeal for me.

    Massage mode first stimulates the breasts to switch to the letdown reflex. Then the pump switches on the expression mode to make milk flow easily and consistently.

    You can also switch between the two modes according to your preferences because every mother is different.

    Throughout the both operations, the pump worked without any fuss or pain.

    It felt almost like a baby was suckling at your breasts.

    5. Hygiene: Spectra S1 is a closed system which means its lot more hygienic then other open systems. 

    Milk never gets in touch with the pump motor. This maybe a significant advantage over Medela in Style Advanced. It also means Spectra S1 is easier to clean.

    Spectra breast pump has a pair of back flow protectors to ensure milk never gets in contact with the pump motor. If multiple users have to use the pump, then each of them will have to use individual collection kits (pair of breast flanges, valves, and back flow protectors).

    6. Sound: Spectra S1 is so silent that I could pump milk even while my husband slept like a baby.

    It’s certainly better than Medela In Style Advanced in terms of noise.

    If you consider that many mothers may take Spectra S1 to their work places and want something non-distracting, Spectra S1 is a boon for them.

    7. Price: Spectra S1 is pricier than Medela PISA but given its efficiency and looks, the price tag can be ignored.


D.M Working

Spectra S1 gets 5 stars from me. From the delivery itself, I had latching issues. No amount of tips and tricks could help me. I had to resort to exclusive breast pumping.

I read your review and felt compelled to buy it. S1 is great at draining my milk, has a great battery life, is super silent and light weight.

It is very comfortable with wide range of suction and speed settings. I take it to work and it is very discreete.

My main grouse is it has wide neck flanges and the bottles that come with it are cheap. The spares are cannot be found in stores. 

Addy Working mom

I love this Spectra S1. It is silent and has a night light. I know for how long I've been pumping. It has adjustable speed and suction levels. It workd even well with the batteries.

Leticia Working mom

I LOVE this pump - Spectra S1. I have used many pumps. Medela PISA, Symphony, and the AVENT pump. Spectra S1 one works the best for me. The unique vibration feature almost feels as if baby suckling. With so many adjustable settings for suction and speed, I was able to zero in on my preferred level. The pump is powerful.  Your Spectra S1 review is spot on!

Hi, I am Marissa. I am a wife of a very supportive husband and mother 3 precious kids. Even though my life is not picture perfect, I have too many blessings to be counted. I am an ordinary mom who has been through some tough times.

I have tried to collate the best information available and write personal & real reviews for the benefits of parents who are confused with the plethora of breast pumps available. I have made an effort to steer clear of technical jargons and used layman language which is understood by people like us.
