I have a special relationship with my Avent Isis breast pump. This little pump is my first pump and also the one I reached whenever I needed a quick pumping session.
But then it was broken a few months ago. So I was in search again for a good quality manual pump. Until I found Medela Harmony breast pump.
I was not so sure at that time despite reading its great reviews. But after I tried it by myself, I’m pretty convinced this pump is on par with my previous Avent pump, and even better. If you are looking whether you should invest in a manual breast pump, especially Medela Harmony, you are in the right place.
In this Medela Harmony manual breast pump reviews, I'll discuss the detailed pros and cons of Medela Harmony, including 6 reasons why you may need this manual breast pump.

HIGHLIGHTS & PROS
1. Patented design: 2-phase expression.
Medela Harmony comes with 2-phase expression design. That means, you can use this pump in massage mode and expression mode, similar to the available modes in electric breast pump.
Here’s how:
- To use the pump in massage mode, press forward the smaller part of the pump handle. By pressing and releasing quickly, you have mimicked the way your baby stimulates let-down.
- Once your milk starts flowing, change to expression mode by pressing the lower end of the handle. You can control the speed and the vacuum by adjusting how far you press it and how quickly you do the press-release cycle.

2. Ability to change flange (breast shield) size.
Since the Medela Harmony design is using 2-piece breast shield, it is very easy to change the breast shield to other sizes, including:
- Medela personafit breast shield, with sizes ranging from 21 to 36 mm.
- Maymom insert (sizes from 17, 19, and 21 mm).
- You can even use other flanges such as the angled ones from Pumpin Pals or silicon flanges. I have yet to see other manual breast pump with this kind of flexibility!
3. Compact and Lightweight.
This manual pump is very compact and would easily fit inside your bag. You can even put the whole thing inside your cooler bag.
4. Totally quiet.
There's no noise unlike electric breast pumps. No squeaky sound unlike Avent manual breast pump. So you can pump discreetly everywhere. In the plane, movie, every where.
5. Super affordable.
Don't worry, this little pump is easy on your pocket.
6. Pump parts are widely available.
Since Medela is a leading brand in breast pump industry, the pump parts are available in most mom and baby stores.
THE CONS
1. Tiring.
Pumping with Medela Harmony means your hand needs to work hard pressing and squeezing the handle.If you have not tried using manual pump before, it can be tiring at first. But once you get used to it, it’s actually pretty quick and effective.
2. Takes longer to empty both breasts
Since this is a single pump, you will need double time to empty each breast. Pump on one side, then switch side.
Hint: you can pump faster using the hack I mentioned below.
WHO IS THIS BREAST PUMP FOR

So you may think, who will need a manual breast pump when there are a lot of electric breast pumps in the market.
A manual breast pump is suitable for several occasions such as for:
- Moms who wants to relieve engorgement. Using a manual pump, you can clear engorgement faster because you can manoeuvre and control the pump (including how to position it against your breast) as you wish. Not to mention there are less part to wash. Additionally, pumping to relieve engorgement does not need to be long. I’d certainly choose my small manual pump over bigger pump for this job.
- As a backup pump for working moms. Yes, you may have a full-size double electric breast pump for you regular use. But sometimes, it is necessary to have a backup manual pump for just in case. In case your electric pump suddenly broke, or you forgot to bring the necessary pump parts and so on.
- Moms who plan to leave their baby occasionally. So you are exclusively breastfeeding and do not plan to go back to work soon. But perhaps you may need express milk while you are having a date night, or simply need to go out for some errands. You may not need to purchase an electric pump for this, a good quality manual pump such as Medela Harmony will suffice.
- You do not respond well to electric breast pump. I hope you are not in this category, but sometimes certain moms simply do not respond well with electric breast pump (and they are doing fine breastfeeding). Before you decide that pumping is not for you, give manual breast pump a try. You may be surprised that you may be able to express milk faster with a manual pump.
- You want to thoroughly empty your breast but have not mastered hand expression. I bet most of you already know by now that dual pumping (by electric breast pump) followed by hand expression is the best way to thoroughly empty your breast. But you have tried and tried hand expression and it’s simply not comfortable. Fret not, you can do manual pumping in replacement of hand expression. I did this too (=D), and I can happily report that this method is one of the secret key of my healthy milk supply.
- You do not have budget for dual electric breast pump. I hear you. I was in the same boat when I was pumping for my first baby. The double electric breast pump at that time was crazily expensive and I could only afford a manual pump. Don’t worry, you will still be able to get pumping done with a manual breast pump. And if you want to cut down the time needed for pumping, check out the following pumping hack.
HOW TO DOUBLE THE EFFICIENCY OF MEDELA HARMONY
1. Pair Medela Harmony with Haakaa silicone pump.

Latch Medela on one breast and latch Haakaa to the other side, switch side once the milk flow slows down, then repeat.
A lot of moms have been using this trick with great success. So whether you can’t buy an electric pump or do not respond well to an electric pump, do try this method.
2. Pair Medela Harmony with a single electric breast pump.
This is what I tried before I found Spectra breast pump. At that time, I only had Medela Swing breast pump and did not respond so well to it. So I pair my Medela Swing with a manual breast pump to make pumping faster. Similarly, you can use Medela Harmony on one side and the electric breast pump on the other side. You may be surprised that you can pump faster this way.
FINAL CONCLUSION
Even though nowadays mom tends to choose electric breast pump, It doesn’t mean manual breast pump is useless. For some moms, using manual breast pump may still be a good and effective way to express breast milk.
And if you want to invest in a manual pump, choose the one with good quality. And Medela Harmony certain fits the bill.
I hope this Medela Harmony Breast Pump review is useful for you who are searching for a good quality manual breast pump.

Benson says
Being a nursing mother isn’t an easy task, so I must commend the effort they put into breastfeeding their kids. I have seen cases where the child is quite lazy at sucking and the mom doesn’t know what to do. In such a situation, this is what is new, but the mom had no idea about this breast pump and she had to keep forcing the kid. In aspect of emptying the breast, are there any more type of pump that can do it easily?
Rina says
Hi Benson,
A manual pump is great for occasional use, such as when the mom needs to leav the Bay for a short period ogni time. But if the baby has problems in latching, it is best to use a more powerful electric breast pump, such as Spectra S1.
Rodarrick says
Great post you have written here and I know any breastfeeding And working mom would find this of immense help just like I will share this with my wife. Having a manual pump would help to store the breast milk for the baby and in return, also give the mum some quiet and personal time. This is great and the medal harmony manual breast pump is simply great to see especially the price wise. It is very affordable and cost effective. Thanks
AJ says
Hi Rina, would a manual breast pump like Medela Harmony help to build up and increase milk supply for Mums struggling with low supply ? I have a spectra S1 double electric pump but bought myself a manual Pump to use in the Middle of the Night pumping session so that I won’t have to wake my baby & husband up from the sound of the Spectra S1.. but I wonder if a manual pump like this would be as effective as a electric one I use for Power Pumping.. I mainly direct latch my baby, and power pump once a day to build up and increase my milk supply.. unfortunately my baby is still on mix feed (formula) as my stash is only enough to feed right away..
Rina says
Hi Anisha,
Typically, it is recommended to use a heavy-duty electric breast pump like Spectra S1 to help improving milk supply. That’s because you will likely to pump several times daily to boost your supply and using a manual pump would be much tiring for that reason. Say if you typically double pump for 20 mins per session, using a manual pump you would need 40 mins (20 mins each breast).
Shahida says
Yes. Medela harmony was my 1st pump when i started my bf journey 11y ago. The pump was amazingly help me to produce at least 20oz at work. Even months later i bought medela fs but harmony was still my 1st love where sometimes it worked better than fs. Now im expecting my new baby and the pump is still in good shape despite i have been using it for 11y for my 4 babies but im not so sure about the performance. If its not working well then i will buy another harmony since im really satisfied with the performance over the 11y.
Rina says
Hi, thanks for sharing your experience Shaida. Wow, eleven years and four babies for one pump, that’s really awesome. So far, I haven’t found any other manual breast pump that works as good as Medela Harmony. Additionally, the ability to change to flange to whichever flange system you prefer makes it even more flexible.
