Two breast pumps that currently dominate the market are the Medela Freestyle and the Medela Pump in Style. Both of these pumps have their advantages: the Freestyle is smaller, more portable, and has a great battery pack, while the Pump in Style is sold at a lower price point and – since it is a more popular pump – it is easier to find replacement parts for it in a pinch.

An important question for anyone looking to buy one of these pumps, though, is which is more effective at pumping milk?
I happen to own one of each, so I decided to do a little unscientific experiment with the two to see which one helped me pump more milk. I did the test by pumping for two full days with each pump – normally, I pump with the Freestyle at home and the Pump in Style at work, but for the purposes of this experiment, I carried them back and forth. I alternated the days so that any hormonal fluctuations (like getting my period) that might have an effect on my output wouldn’t skew the results.
Here are my Medela Freestyle vs. Pump in Style results:
Day 1 (12/10/13): Medela Freestyle
As I said above, I normally pump with my Freestyle at home and my Pump in Style at work, so I brought it to work and back with me today. Packing up all of my pump parts and getting the bag together reminded me why I keep a pump and pump parts at work and just transport the bottles back and forth. It is so much easier!
(I had to bring the PIS home with me, too, so that I’d have it for my first morning pump tomorrow. I’m sure that I looked very put together with my multiple breast pumps on the train.)
Here’s my output:
- Pump #1, 6:15am – 7.5oz
- Pump #2, 11:30am – 8oz
- Pump #3, 2:30pm, 5oz
- Pump #4, 6:45pm, 6oz
- Pump #5, 9:15pm, 3oz
Total for Day 1 of Pumping with the Freestyle: 29.5oz. A pretty good day! We’ll compare it to tomorrow.
Day 2 (12/11/13): Medela Pump in Style
- Pump #1, 6:15am – 7oz
- Pump #2, 9:15am – 8oz
- Pump #3, 2:15pm – 6.5oz
- Pump #4, 6:15pm – 4.5oz
- Pump #5, 9:15pm – 3oz
Just a general observation about the two pumps – since I usually don’t pump at home with the Pump in Style, it required a bit of an adjustment. I always use the battery pack with my Freestyle, and the chair I sit in isn’t really convenient to an outlet. Also, during the early morning pump, it’s easy for my baby to pull the tubing out with the Pump in Style. I might have to get up before her to pump next time.
Total for Day 2 of Pumping with the Pump in Style: 29oz. A little less than yesterday, but this is probably not a statistically significant difference.
Day 3 (12/12/13): Medela Freestyle
- Pump #1, 6:00am – 8.5oz
- Pump #2,11:00am – 9oz
- Pump #3,3:00pm – 5.5oz
- Pump #4,6:00pm – 4.5oz
- Pump #5, 9:30pm – 3oz
It’s kind of weird how my body makes 9oz from 6am-11am, but only 8.5 overnight, no? I have no explanation for this.
Total for Day 3 of Pumping with the Freestyle: 30.5oz. Best day so far!
Day 4 (12/16/13): Medela Pump in Style
My pump throwdown was interrupted by a really painful clogged duct on my right side, which required me to pump much more often than normal to clear. I took a break from the experiment until it was resolved so that didn’t skew the results.
Here’s what I got when I was able to resume my normal pumping schedule with the Pump in Style:
- Pump #1, 6:00am – 8oz
- Pump #2,10:00am – 8oz
- Pump #3, 3:00pm – 5.5oz
- Pump #2, 6:30pm – 4.5oz
- Pump #2, 9:30pm – 3oz
Total for Day 4 of Pumping with the Pump in Style: 29oz.
Here are the Medela Freestyle vs. Pump in Style results charted:
It looks like the Freestyle is the winner, with an average of 30oz, as opposed to the Pump in Style’s 29oz. I prefer the Freestyle for other reasons, so it’s good to know that the milk output is slightly higher with it (for me, at least).
Obviously, this is not a scientifically rigorous experiment, and your results may be different. However, it’s good to know that, generally speaking, you are likely to get about the same milk output with either the Freestyle or the Pump in Style, and you can make your decision based on other factors like price and convenience.
