Medela PISA Vs Spectra S1 – Medela and Spectra breast pump reviews blog

 Medela PISA Vs Spectra S1


pnsa pump(2)

This is sharing from a singapore mummy, Audrey Yeo which I obtained from a FB group administrated by her. I learn a lot from this group and thus would like to share the review as follows. You may also join her FB group to get more updates and notifications.


S1 is a hospital grade pump.

It has a very unique suction where it vibrates ur nipple during suction, triggering your letdown to come faster and also helps to stimulate milk production unlike other pumps which will just pull and release.

It allows you to customize your pumping experience. You can set the suction power and suction duration separately. It is Close System, has a timer(auto off at 30mins) and night light(under handle) to make it easier to pump at night. Has a massage button to help achieve a letdown faster. In-built rechargeable battery which can last around 3 hours of pumping

PISA  is medela’s best normal range pump with the strongest suction. It is an Open System.

It starts off with 2mins of fast suction before it changes to slower longer suction automatically. It comes with a detachable battery pack which requires 8-10AA batteries.

PISA  Cycle: 48-74, stimulation at 117 (12Levels)

S1 Cycle: 38-54, stimulation at 70 (12 Levels)

Experiment made on PISA Level 8 Vs S1 Level 6 (based on the same suction strength and cycle) for 6 sessions each pump.

PISA Cycle: 48, Stimulation 117

S1 Cycle: 46, Stimulation 70

Time taken: 20mins

End results: S1 have an average of 30ml of extra yield as compared to PISA.


S1 weighs 1.12kg and PISA is 1.95kg(1.6kg without batt).

S1 is much quieter than PISA

S1 have separate individual setting for suction strength and duration, PISA has a JOINT suction strength n duration setting.

PISA with eneloop rechargeable battery can last more than 15pumping sessions, S1 last around 3hours of pumping session.

S1 is much bulkier than PISA.


S1 is more suitable for people whose concern is more about increasing yield and also to have a more comfortable pumping experience as u can control the suction strength n duration individually. It is also suitable for mummies co-sleeping with their babies as it is a very silent pump. Recommended for Home use, in the Car, and Office use. S1 is also suitable for people who are more concern about budget as it is around 50% cheaper than PISA.

PISA is more suitable for pumping on the go, or for traveling as u will not need to worry about not having enough battery charge as it is very convenient to get AA batteries in convenience store. It is also suitable for people who are more brand conscious as Medela has been a trusted brand and it has a service centre in Toh Guan.

Pump at work Ep 5 – Effective storage on the go

For full time working mummy, you must have been bringing tons of bag to work right?

When I was an auditor, I have a laptop bag, handbag, nursing bag and a recycle bag that I keep my files. It is very bulky and every time when I move around, I look like I am moving house! LOL

Then after I changed my job, I have a better life. I bring handbag and a nursing bag and improved my storage more effectively.

I keep my pump in a container (you can use zip lock bag as it actually save more space) so that I can rinse my pump using the container. It look like this.


Container 🙂













You can read about how I wash my pump here.

Then I keep this together with my cooler bag in my Medela bag.



Medela bag can fit in:

  1. Small bottle of bottle detergent
  2. Hand santinizer
  3. Cooler bag
  4. Pump
  5. Pump parts packed in container
  6. Storage bag
  7. Small napkin x 2
  8. Charger
  9. Wet tissue
  10. Tissues
  11.  Handphone
  12. Clutch



It give a lot of space and it looks neat. A lot of compartment and easy to get hold of things. I tried put all the things to my handbag but I get a little bit messy when I try to search for a tissue 😛

It ease my washing as I can use the container straight – rinse and keep in fridge.

The only thing is everyone know I am pumping because of the Medela bag!


Zip lock bag 🙂



If you decided to use the zip lock bag way, it save ample of space for you. Chuck this in your hand bag and you can move around.

I will only do this when I only pump once outside or I will bring two set of parts because obviously I am in a rush when I do this.



It save up a lot of space but it gets a bit messy when I want to do my washing. I normally do this when I am rushing and I will pick up two sets of pump and wash all of them when I am home.

Change the Zip lock bag for every use ya.. Hygiene is important 🙂


Soft bag 🙂

If you want to bring out all your pumps and put in your handbag, you can do this way too.

Make a guess how much does this cost?

Only SGD2! You believe it? This is actually a very good idea if you intend to bring only one bag.

Also,this is canvas material therefore it is waterproof and you would not wet the outer part of the bag if you wash put back your pump parts after you wash it.

Good idea?

*credit to mummy drey drey for this fab idea



It is very very compact. Light packing and on the go style. But with this I actually take longer time to wash my pump because I need to wash and dry up the part a bit before I can keep my pump away.


Pumping at work Ep 1 – Wash and Pump

Officially start work.


For my whole confinement leave, I have been planning and thinking what to bring and how to pump during my work time. Worry that I could not pump on time, what boss and colleague would think of my pumping schedule, heavy bags and things to bring and tadaaa.. I ended up bringing three bags and one ice box to work on first day of work. Such a drama queen.

Then moving forward I can actually pack my stuff better in a more compact way.


Let’s take a peep what is in my bag 🙂


  1. Medela freestyle pump
  2. Assembled parts (breastshield with valve and membrane)
  3. Cover
  4. Small bottle of pureen bottle wash liquid cleanser
  5. Wet and dry tissue











All these can actually fit in my medela bag – Awesome!

Often, people ask me,


How you wash your pump?


Well, I do not wash my pump – in a way. What I do is, I would rinse them in hot water and put them back in my tupperware container and keep in fridge for the next use.

Occasionally, if my breast milk is oily then I will put in two drops of liquid cleanser into the water to soak my pump. I do not disassemble the parts but just close the container and toss my parts in the water. Then, I will rinse them twice, warm water and hot water. After that I will keep them in the fridge for the next use.

Some mummy may say the liquid cleanser will get stuck in between the breastshield and valve if I do not disassemble them. So I tried to observe and I do not notice any bubbles. The parts feels squeaky clean.

Once, I met a few colleagues in the nursing room and they share with me how they clean and keep their pump parts.

  • Mummy 1. Instead of keep the parts in container, she put in a zip lock bag. After every pump, she will use the wet tissue (she is using pigeon hand and mouth wet wipes) to clean the membranes, valves and breastshields.
  • Mummy 2. Another mummy keep the pump parts separately, using both container and air dry bag. After every pump, she will disassemble the parts and wash them using liquid cleanser (sometimes without) and brush. She will air dry the parts using a special air dry bag and keep the parts back in container once they are dry.

Out of curiosity, I observe how different it makes between them and myself, in terms of time take for each pumping session.


Review 1 time taken for each pump


  • Mummy 1 She pumped for 20mins (double pump) and spend 2mins to clean her pump parts. In total she took only about 25-30mins to get back to desk.
  • Mummy 2 She pumped for 30mins (single pump and 15mins for each breast) and 15mins to wash and keep her pump parts. In total she took about 45-60mins to get back to desk.
  • I pumped for 20mins (double pump) and spend about 5mins to clean the pump parts. In total I take about 30-35mins to get back to desk.


Review 2 things to bring to work


  • Mummy 1 She use her handbag (medium size long champ) to put everything in. Fabulous.
  • Mummy 2 She use her autumn bag which is bigger than the mummy 1’s bag.
  • I use my medela bag and in fact I can still put in my purse and mobile in and ready to go. Medela bag is about the same size as the medium size long champ which have a lot of compartments. Super useful.
