This is a detailed reviews of Spectra M1 breast pump. I got curious on this little pump ever since I tried Spectra S1 breast pump (click here for my Spectra S1 detailed reviews).
A lot of moms rave on its powerful suction (comparable to S1), yet it comes in a much smaller and lighter design, which make it very portable to tote in the go. So, how’s my experience trying out this little breast pump. Read further to know more.

What You Get Out of The Box
Depends whether you buy it as a single breast pump set or dual breast pump set.
If buying as dual breast pump, you’ll get:
- Pump motor
- Tubing (x2)
- Back flow protector (x2)
- Breast flange (x2)
- White valve (x2)
- Wide-neck milk bottle (x2)
- Bottle caps (x2) and sealing discs
- Bottle teats (x2)
- Bottle stands (x2)
- Power adaptor
- T-connector (to enable double pumping)
Here’s a great video by Ellie showing you the features of Spectra M1 breast pump.
I got mine as a single pump, so the parts are less, and I’ve changed the bottle to my Avent bottle (preferable since it is more durable).
If you get yours as a single pump and want to upgrade to dual breast pump, here’s what you need to get:
T-connector allows dual pumping
- Tubing
- Back flow protector
- Breast flange + valve
- T-connector (choose the new version if possible, since it allows switching from dual to single pumping seamlessly).
Some merchant sells items 1-3 as a set (called Spectra collection kit) with lower price.
Highlights of Spectra M1
#1 Super strong suction
Love, love, and love this. Don’t let its physical size fool you. Despite its small size, the suction strength of this breast pump is super powerful. Remember I told you that I used level 10 (out of 12 available suction levels) in Spectra S1? With Spectra M1, suction level 3 (out of 5) is powerful enough to drain my breast.
Just like its big sister, M1 has a maximum suction at 300 mmHg, higher than other breast pump brands.
#2 Unique suction for more comfortable pumping experience
M1 expression phase starts with a little bit of nipple vibration followed by a long and deep suction. I’ve never felt any discomfort despite using it at pretty high suction level. Yes, I’ve tried level 4 and 5 , no pain.
#3 Adjustable suction strength + cycle speed (5 levels)
Spectra M1 has 5 different settings for massage mode and expression mode. The speed is automatically adjusted as the suction strength increases/decreases. Initially, I thought, 5 levels may not be sufficient, but after I tried it by myself, I can attest that 5 is just nice. The suction strength varies quite evenly across different levels. So if you are not a fan of powerful suction, you can still use this pump, but simply use lower level, e.g. level 1 or 2.
One thing to be noted. As the suction increases, the cycle speed decreases. That means, with strongest suction = long suction. While I’m not particularly a fan of long suction (I always thought it slows down the pumping process), with M1 it feels different. The cycle speed setting is just RIGHT. Yes, with much longer suction, I can actually see that M1 is more effective in drawing out milk from the breast. So, eventually, it empties breast faster with less number of cycles. So, again, I think, it is so well-designed such that the settings between suction strength and cycle speed really match each other.
#4 Closed system
Spectra M1 has back flow protector installed between its tubing and breast shield. This i
s to prevent breast milk or moisture to enter the tubing (and subsequently the pump motor) which may create mold and damage the motor. This makes it a more hygienic pump, with longer durability of pump motor, and suitable of multiple user sharing. Each user simply needs to have her own milk collection kit (breast shield, valve, and back flow protector).
#5 Portable
This is the WOW factor for Spectra M1. Imagine, despite its light and small design (500 gram is very light), this breast pump has powerful suction, enough selection of suction/speed levels, closed system, and can be used for both single and dual pumping? For me, it’s really amazing and such a steal deal in its current price (check the latest price here!) I believe this factor is a plus point especially if you plan to tote the breast pump around for work, traveling, and pumping on the go.

Other pros:
#1 Built-in rechargeable battery
With rechargeable battery, you can pump any where without needing to be close to electric plug. The full battery can last for 1.5 hour pumping time. With typical 3-5x pumping session daily, you will need to charge the battery every day.
There is a battery indicator on the pump panel, which is nice so that you know when you need to charge. And one more plus point, the suction strength does not vary based on battery power. I’ve been pumping with battery indicator showing that it’s almost empty, yet the suction is as strong as if the battery is full.
#2 Auto shut-off after 30 minutes
This is a safety feature that if the pump has run continuously for 30 minutes, it will automatically turned off. Great for mothers who pump in wee hours while battling off sleepiness.
#3 It memorizes our last pump setting
This is a pretty nice feature, considering not all breast pump has this. So, you don’t need to adjust the suction level every time you pump. Once you have a comfortable level, the pump memorizes this for you (this include suction level for both massage and expression mode, and they can be different setting). For example, I am using level 5 for massage mode and level 3 for expression mode, and the pump memorizes these 2 settings.
Are you pumping at work?
You know that every minute counts…
Stop wasting too much time and streamline your pumping routine with these super-handy pumping essentials.
The cons:
#1 Pump motor is not for heavy usage.
This pump is designed for typical 3-5x daily use. If you overuse this, say, by pumping 8x a day or more, the motor will die very quickly. I’ve heard quite a number of stories of Spectra M1 stop operating even before 6 months because it was used for exclusive pumping. So, EP mamas, if you are interested in Spectra, don’t buy this. Choose Spectra S1 instead.
#2 Limited flange size and not compatible with Pumpin Pals
Currently Spectra offers only 3 sizes: 24 mm, 28 mm, and 32 mm, which is pretty limited compared to what offered by Medela / Maymom. But fret not. You can connect Medela breast shield to Spectra pump using this simple hack. Alternatively, you can buy Spectra-compatible breast shield by Maymom (it contains a little connector to connect Medela / Maymom shields to Spectra back flow protector => this little piece is so valuable).
#3 The pump motor can get noisier over the time.
While a new Spectra M1 would be nearly silent, with continuous usage the motor gets noisier, even though it is still in acceptable level. I think this is a typical problem for breast pumps with small motor. My Medela Swing also has this exact problem. With that said, once it gets noisy, I won’t be comfortable using it to pump in my office cubicle (working moms, take note of this!)
#4 No LED display & night light
Spectra pump panel, red light indicates massage mode. Central panel indicate suction level, and top panel for battery indicator.
Unlike S1, Spectra M1 does not have LED display. The pump panel consists of power button, toggle button to switch between massage and expression mode with light indicator (light is on during massage mode), + and – button to increase/decrease suction, and battery indicator. So no timer showing you how long have you been pumping. And no night light option. While I think this simple design is more than sufficient for my usage, it may not for mothers used to pump in wee hours. If you are looking for similar portable breast pump but with LED display and night light, do try Spectra 9+ breast pump .
#5 Inconsistent mode when turned on
Spectra M1 would turn on in the last mode before it was turned off. So, if you turned it off in expression mode, the next time it turns on, it will be expression mode, and vice versa. Noting that the suction in expression mode is quite powerful, I would suggest you to ALWAYS switch to massage mode before turning off the pump.
#6 Need to press button firm enough
The buttons in the pump panel are kind of flat button, hence it can be misleading thinking that it will response with soft touch. Wrong, press firmer just like you press regular button.
Who is this breast pump for?
Spectra M1 is perfect for working moms and stay at home moms who pump a typical 3-5 times a day (or even less). I guess the portability is one of the best-selling factor which makes it appealing for any mothers.
If you are exclusively pumping, or trying to build your supply in the early days when your baby unable to nurse effectively, this pump will work, but may not be durable enough for you. Go for Spectra S1, instead.
Final Conclusion
Spectra M1 is a great little pump which offers portability and simple yet nice design and great suction/speed variation. Powerful suction and portable are two of its best-selling factor. Combined with its very affordable price, it is really a best deal for moms. Unless you need a heavy-duty pump (which M1 is not), I would strongly recommend you to try Spectra M1. You won’t regret it!

Spectra M1 is a nifty little pump which can be transformed to a double pump. Nice looking, closed system and poerwful pump makes it my favorite. But the much loved LCD display of S1 is missing in M! 🙁
Hi Mariassa,
I agree with you. This little pump is a nice one, the design may be simpler, but it gets the job done.
Not all moms want to have LCD display anyway.
Have you tried Spectra 9+? It is even smaller and lighter than Spectra M1, more suction levels ( I think it has 10 instead of 5), and LCD display. I heard rumour that its suction is slightly lower than M1, but not so sure since I haven’t tried by myself.
Hi! Was planning to buy M1, but Ive read somewhere theres a new m2 and old m1(yours have cimilre and the new one have spactra written). The picture you posted is the old model, I think, is it okay to go for that one? Since youre not having any negative feedback about it, meaning its okay right? And how long did you use it? Is it durable? Planning to go back to school. Hoping for your reply. Thank you very much!
*M1 – new M1 and old m1. They said new m1 is much quiet and smaller? But did not further discuss the suction or what.
Hello Lucky Bum,
Yes, there’s a new and old M1. The one I used here is the old model. I haven’t tried the new M1 so I can’t comment on the suction difference. However, I feel that even the old M1 has quite strong suction as I said in the article.
I didn’t use this for long since at that time I already had pectra S1 and get used to it.
As long as you don’t overuse it, I believe M1 is pretty durable. I’ve heard stories of M1 broke down before 6 months, but that usually because the pump was abused for exclusive pumping.
Hi Rina,
Thanks your articles helped me a lot. Do you have any review on spectra 9+? I’m planning to get another pump as I already hv s1 (but it’s too big to bring in to work). I’m lost in between s9+ and m1 , – my best replacement of my s1 .:-)
Tia.
Hi Shobee,
I haven’t tried Spectra 9+. Was wanting to buy it out while I was still breastfeeding my daughter, but then I got pregnant with no 3 and was afraid to try pumping during pregnancy.
I guess I need to wait until baby # 3 arrives to try out.
But from what I heard, I got a mixed impression.
Amazon reviews have been great in general, but heard rumours that the suction is not as strong as M1
But my feeling is, as long as you don”t use tthe stringest suction level in S1 (which I don’t think most people need), then it should be fine.
Hi. James from Cimilre Korea just dropping a quick post to let everyone know that the above M1 model is the old version of the M1 pump from Cimilre & Spectra.
Cimilre is now an independent brand with new line of pump products (F1 & S3) in the market.
With innovative technology and new appealing design, Cimilre offers a new experience in breast feeding in more convenient and efficient ways.
Please check out our website at : http://www.cimilre.com for more information.
Thank you and have a wonderful day! 🙂
Hi James, thank you for your updates. I was aware of Cimilre and am excite to try the new breast pump lines. F1 is increasingly popular in Singapore.
I just bought spectra m1 and how to know whether it is charging or not? There seems to be no any indicator showing the battery is charging? Have you guys facing the same problem as mine? Or is there anything wrong with my adapter?
Hmm.. unfortunately I have given away my Spectra M1. I remember there’s some charging indicator, but I may be wrong.
Is Spectra m2 same as m1..I cannot find any reviews on it.
Hi, they are very similar. I think the difference is M1 using built-in battery whereas M2 using AA batteries.
