Ever since my Avent breast pump broken a few weeks ago, I realized that I must look for an alternative breast pump that I can trust. With the fact that Philips has discontinued Avent Isis product range, I could no longer purchase replacement spare parts easily. So once again I’m on the look for a new breast pump. That’s when I found Spectra S1 breast pump.
This so-called hospital grade pump receives raves reviews from exclusive pumpers and mother of preemies for helping them building and maintaining their milk supply.
But... is that really true?
I took my chance to get this breast pump, and boy, finally I found my DREAM BREAST PUMP.

RELATED: Finally, there's another hospital grade breast pump that is on par with Spectra S1, or even better. Click here to read my detailed review of Super Genie breast pump from Pumpables.
WHAT YOU GET OUT OF THE BOX
- Pump motor (with built-in battery)
- A pair of breast flanges + duck bill valves
- Two bottles with teats and sealing discs
- A pair of back flow protectors
- Two sets of tubing
- AC adaptor
THINGS I LOVE FROM SPECTRA S1
1. Hospital grade with max suction of 300 mmHg
Unlike other breast pumps which reach maximum typically at 250mmHg, Spectra offers much higher suction limit. While not all mothers will need this maximum suction level, this extra is definitely an added advantage. Different mothers have different suction preferences.
Wider range of suction means more mothers will benefit from this pump.
And there's a higher chance that you'll find your comfortable suction level with this pump.
2. Great for building up and maintaining milk supply
While I don’t have personal experience on building my milk supply since the beginning with this pump. I can easily see that it is powerful enough for establishing and maintaining a good milk supply.
I've read great reviews from exclusive pumpers and mothers of preemies and twins who need to build up their supply and they all LOVE this breast pump. This pump also one of the most favorite pumps for mothers with low milk supply issue.
I myself tested the efficiency of this breast pump by comparing the amount of milk expressed by Spectra S1 and the milk expressed with Avent Isis Manual Pump (being my gold standard of emptying breast most efficiently) right after pumping with Spectra S1.
I’m happy to report that Spectra is able to drain my breast thoroughly with up to 90% efficiency. I still get some milk out with my Avent Isis right after that, but the amount is typically less than 0.3 oz.
3. Unique suction with vibration, maximizing comfort
I can attest that Spectra S1 has a powerful suction.
I am used to Avent Isis breast pump which is famous for its strong suction. With Spectra S1, I found myself comfortable at suction level 10,which is comparable to my Avent Isis maximum suction. The surprising thing is, despite its strong suction, I barely feel any discomfort.
I suspect this is due to Spectra S1's unique vibration. No wonder they have a slogan: "our pumps don't suck, they SUCKLE."
This is how Spectra pump works: at the beginning of sucking phase, it vibrates the nipple, then followed by a long deep suction.
To me personally, the vibration mimics the way a baby suckles the nipple in direct nursing. Hence, creating a comfortable feeling.
This is a totally different feeling compared to when I use the highest suction in Medela system, in which the strong suction comes with nipple discomfort.
4. Super quiet (nearly silent!)
Before using Spectra S1, I always thought that my Medela Swing is considered a quiet pump.
But what a difference with Spectra. It is super quiet!!! Even my family member noticed this right from the beginning.
This makes Spectra S1 perfect for those wee-hour pumping (when you don't want to wake up anyone else -especially your little one) and at-desk pumping once you go back to work. Yes, your colleagues won't even notice that you are actually pumping unless they are staring at you.
5. Closed-system pump
Spectra breast pump has a pair of
This fact makes Spectra breast pump more hygienic, more durable pump motor, and suitable for sharing between multiple users. Each user just needs to have her individual collection kit.
6. Highly customizable (suction strength and cycle speed can be adjusted independently)
The massage (let-down) mode has 5 different suction levels and cycling speed up to 70 cycles per minute. For comparison, Medela pump only has a single cycling speed for massage mode (112 cycles per minute).
I found the massage mode quite effective in stimulating let-down reflex. Typically I achieve my first let-down after 1 minute, and the second let-down after 3-4 minutes (note: the second let-down was initiated after the milk flow slows down after expressing with the first let-down).
The expression mode is even more powerful with 12 different suction levels (the highest at 300 mmHg) and cycle speed between 38-54 cycles per minute.
The breast pump automatically saves your last used setting , so that you can use exactly the same setting every time you pump.
Other features which are NICE:
- Dual or single pumping. Spectra S1 breast pump allows easy switching between dual and single pumping by unplugging one of the suction tube and cover one of the tube connector.
- LED display, which allows you to see how long you have been pumping, which mode are you currently in (massage or expression mode), and which suction level /speed you use.
- Night light. This is a pretty cool feature if you pump in the middle of night. Currently, I don’t need this, but I can relate how useful it is for exclusive pumping mamas who need to express at regular interval including at wee hours. The are 2 levels of brightness as shown in the photo.
- Auto shut-off after 30 minutes. The pump will automatically turns off after running for a continuous 30 minutes. This is a safety feature, just in case you fall asleep during wee hour pumping session and lets the pump running all the time.
Different levels of Spectra S1 night light
I've heard it again and again, a lot of moms are raving about Spectra S1, whether it is in motherhood forums, Facebook groups, reddit, and Amazon. You can read more reviews about Spectra S1 here.
THE CONS
1. Bulky (compared to other personal breast pumps)
With size of 20x20x17 cm and weigh around 1.1 kg, this breast pump is rather bulky. I tote it every day to my office and I need a separate bag to house the pump alone.
PS: If you are looking for a pump bag that will fit your Spectra S1 and all your pumping accessories (bottles included), plus all your laptop, purse, etc, I strongly recommend you to check out my latest post about the top 5 breast pump bags for Spectra S1. So many choices available now!
And did I mention that these bags are very stylish? No one will expect thatthey are breast pump bags.
Oh, btw, if you don't like a bulky breast pump, Spectra has a more portable model (M1 and Spectra 9+) but with some limited features. Read my Spectra M1 review here and my Spectra 9+ review here.
2. Marking in bottles disappear pretty quickly
Spectra breast pump now comes with wide-neck bottles. While they are more stable compared to its previous version (the one pictured above is the old version), I've noticed that the oz marking easily disappears after a few months. If you plan to use Spectra long-term, I'd suggest you to invest in better quality bottles. I myself prefer to use Avent natural/classic bottles.
Which bottles compatible with Spectra spectra breast pump (other than Spectra bottles, of course):
- Avent natural / classic bottles (holds 4 oz)
- Nene Supply breast milk bottles (holds ~ 4.5 oz)
- Maymom wide-mouth collection bottles (holds 4.7 oz).
- Kiinde breast milk storage pouch (this is a breast milk bag, but you can pump directly to it, it has various adapters to fit major breast pump models, including Spectra).
For more compatible bottles and breast pump accessories, check out my latest post on Compatible Spectra breast pump parts and accessories.
3. Start on expression mode
This is a small thing, but I find it not so intuitive.
But this breast pump starts in expression mode. So you need to press the massage button every time you turn on the pump, to stimulate let-down.
That being said, if you end your last pumping at suction level 11, then it will start at level 11 again, which can be a ‘shock’ if you are not aware.
The best practice is to always lower down your suction level right at the end of your pumping session, so that next time it will start on low again.
4. Limited breast flange size
To date, Spectra offers 24-mm size flange (this is the standard size which comes with every new pump), 28-mm, 32-mm, and 20-mm breast flange.
I secretly wish that they support a broader range of flange size (especially smaller size) just like what Medela has, or Maymom.
However, I found a simple solution on how to use Medela / Maymom flange with Spectra breast pump, while keeping its backflow protector attached. Click here to learn how to connect Medela shield to Spectra breast pump.
Update: Maymom releases a special adapter that can connect Medela / Maymom breast shield to Spectra breast pump directly. Or, alternatively, you can use a long-stem back flow protector to connect Medela breast shield directly to the backflow protector, no extra piece required. Genius!
You can connect Medela breast flange to Spectra, while still using the back flow protectors.
Watch it in action!
Here’s a video review about Spectra S1 breast pump by BabyScoops (special thanks to Ellie for letting me putting her video in this review).
A few notes about things mentioned in the video:
- All prices mentioned are in SGD (Singapore dollar).
- Avent VIA cup system (can be bought from Amazon) allows you to pump, store and feed from the same container. No milk transfer, so less wastage. These cups come in 2 different sizes: 6 oz (180 ml) and 8 oz (240 ml), and they are stackable (thus, easy to store)
WHO IS THIS BREAST PUMP FOR?
This is a heavy-duty breast pump. It is suitable for mothers looking to
- Build their milk supply
- Maintaining their supply (especially when they cannot latch the baby directly).
- Exclusive pumpers, and
- Working moms
- For power pumping (due to its heavy duty nature)
SPECTRA S1 Vs SPECTRA S2
Spectra has two models of hospital-grade pump, S1 and S2. They have exactly the same size, shape, and features and functionalities, except that Spectra S1 has a built-in battery while Spectra S2 does not.

PS: Amazon is offering a very good deal on Spectra S1 ( It is way less compared to price at www.spectrababyusa.com). And now, it even ships to Singapore. Check it out.
FINAL CONCLUSION
Spectra S1 breast pump is a great pump to have for mothers looking to establishing, building, and maintaining their milk supply.
If you are a mother who has difficulty in building up your supply, exclusive pumper wanting to maintain steady milk supply, mothers of preemies, and working moms looking for a heavy-duty breast pump, then I strongly recommend Spectra S1.
Again, this breast pump receives a lot of great reviews. I’m just one of them.
To recap, here's the benefit you'll get with Spectra S1:
- Strong suction (up to 300 mmHg), with 12 different suction strength levels.
- So much comfort (this breast pump suckles, not just 'pulling' your nipple)
- Ability to adjust cycle speed and suction strength independently (this is WOW)
- No need to depend on power outlet due to its built-in battery that lasts up to 3 hours! (You can pump in your kitchen table, car, cubicle, tiny store room, literally any where)
- Digital display (know exactly which level you are in, how long you have been pumping, night light)
- Super quiet (no more waking up your hubby or baby in the middle of night)
- Hospital grade (heavy-duty motor, long lasting)
- Closed system (more hygienic, more durable)
I'm totally in love with this breast pump and a lot of mothers too. I believe you will love this breast pump too and it will be the best buddy in your breastfeeding journey.
Here's another rave review for a mom who bought it:
I bought Spectra S1 for my second baby and carefully measured my correct breast shield. Guess what? My pumping yield is 150% up !! (compared to what I used to get with my first baby). Woohoo...
Want to get great results just like Linda has? Try Spectra S1, you won't be disappointed.
I hope this review helps you to determine if Spectra S1 is suitable for your need. Feel free to ask me questions about this breast pump if you are in doubt.

john says
lol so this doesn’t really apply to me but I found it interesting nonetheless. If I ever needed breast supply things or something then I would definitely hit you up. The images were straight and too the point and I found the website to be very informative overall. Very good job overall! A nice design and a very good layout makes it accessible for the reader.
Rina says
Hi John, thanks for the compliment. If you ever have friends or relatives who are in need of a good breast pump, please refer this article to them.
sc88 says
Hi Rina, thanks for the information! A few months after our son was born my girlfriend also had trouble producing enough milk, we tried a pump but that didnt work out so well so we had to switch to using milk from a bottle… but I think if we tried another pump or did some more research on it maybe we would have found a suitable one… Il definitely keep your site in mind if I hear of someone who needs advice on breast pumps or breastfeeding…
Something else that girlfriend experienced was pain while breastfeeding, im sure theres alot of women or their partners looking for advice on that too (perhaps you could write a post or something on that… just a suggestion 🙂
Rina says
Hi Sc, Yeah, definitely having the right pump also plays important role when there’s milk supply issue. I can totally relate how challenging it is to continue breastfeeding up to 6 months and even more. This is even more true when the mother starts working or studying and need to be separated from baby.
It also took me quite a while to find the ‘right-fit’ breast pump for me, so researching before buying breast pump is very important to do.
Pain while breastfeeding is typical during the first few days of breastfeeding because both mother and baby are learning the best position to nurse, but prolonged pain is a sign of breastfeeding problem, perhaps from incorrect latch. I’ll add this to my list of blog post ideas. Many thanks.
Dmitriy says
Hi Rina,
This review is just in time, as we’re having a baby soon (the third one, actually), and I was thinking of purchasing an electric breast pump for my wife. We used a manual philips pump before and it was great, but manual pump isn’t always convenient to use, actually. I think S1 will be a very good improvement for us, thank you for the valuable info!
Rina says
Hi Dmitriy, congrats on your baby no 3. Yes, I agree with you that manual pump may not be convenient to use. Nowadays a lot of moms prefer electric ones. I also used philips avent manual pump and love it. Spectra S1 is my other lover which is in par with Avent in terms of efficiency. I hope the reviews is useful for you and your wife.
Do let me know how’s her experience with S1 later on.
Dmitriy says
Sure, I’ll let you know, but it will take a few months – we expect our baby to be born in the middle of January 🙂
Nicole Chen says
Hi I have take a spectra 1 from my Last time baby sitter Daughter. She give me as she find it good to use. She only give me plug and the pump. May I know what are the accessories kits that I need to buy. I want to go buy online through Qoo10. But there is so many spare parts for spectra that I don’t know which one to buy or what to buy. Can u give me a list of what should I buy. I have already bought tommy tippee milk bottle so is there anyway the tubing can connect directly to the bottle or I just buy spectra bottle?
Rina says
Tomme tippe is not compatible with Spectra, unfortunately. You need to buy the tubings, backflow protector, the breast shield sets (the flange and the duckbill valve), and the bottle (Spectra, Mam, or Avent). Buy 2 for each.
Where do you stay? If you are in Singapore / Malaysia, I highly recommend buying from Kulily.com or Bingbling (authorized distributor of Spectra). Tracy (the owner of Kulily is super helpful. You can always ask her if you are in doubt).
Let me know if you need more help =)
Debra says
I learned so much about what to look for in a breast pump from your article. This is great.
In regards to the suction, such as 250mmHg, what does the Hg stand for?
I didn’t know that vibration of the pump can offset the discomfort that can be typical. I also leraned that there are some systems out there that can be adjusted independantly of eachother.
What a great pump this Spectra is.
Rina says
Hi Debra,
I am glad that you learnt something from the article.
mmHg is also known as mm of mercury (Hg is the symbol of ‘hydrargyrum‘, the chemical name of mercury). mmHg is a unit of pressure, just like Pa (Pascals). I don’t know if you can recall this, but I believe we learnt about it at physics lesson in our secondary school years.
Yeah, I was also surprised that this little vibration does wonder to the pumping experience.
I especially love that the suction and the speed can be adjusted separately (most breast pump models, such as Avent, Medela PISA, don’t have this capability).
