1. Different Generations of Medela Breast Pumps
Medela breast pumps undergo continuous improvements, leading to multiple generations. To date, Medela has undergone six iterations to meet users' needs. Here's a breakdown of these improvements:
1.1 Medela Breast Pumps from 2003 to 2006
During the early years of its presence in the Vietnamese market, this model wasn't prominent or optimized. Many mothers were still predominantly using formula milk, neglecting breastfeeding. An identifying feature of this model is its limited 3 or 5-level suction.

1.2 Medela Breast Pumps from 2007 to 2009
Stepping into 2007, Medela began to expand its presence in the Vietnamese market, marking a breakthrough in product development. This generation boasted 7 suction levels, along with the distinct 'pump style' green label on the machine body. Despite being relatively rudimentary, these machines gained trust among many customers.

1.3 Medela Breast Pumps from 2010 to 2013
During this period, Medela introduced another wave of innovation. The company changed the control button to offer 7 suction modes, which were visibly clearer and easier to use. Additionally, the Medela logo was printed in gray on the machine body, while the 'pump in style advance' text was moved below in the same gray tone.

1.4 Medela Breast Pumps from 2014 to 2017
This generation saw no functional improvements but focused on design updates. The 'pump in style advance' text was relocated to the center, and the casing adopted a black and white color scheme. Several items were removed from the package, including a reduction of 1 storage box for batteries, 1 bag containing a thermos bottle and ice pack, and even 2 milk bottles.

1.5 Compact Medela Breast Pump 2018 Edition
Compared to the 2017 model, the 2018 Compact Medela Breast Pump underwent a color change to white for its casing. This white color ensures better product recognition. Additionally, the product now comes with 2 additional 27mm massage funnels.

1.6 Compact Medela Breast Pump 2019 Edition
By 2019, the Medela pump line received an update. Instead of using a 110V power source, it shifted to a 220V power supply. This was the sole improvement for this model year but proved significant for the Vietnamese market as it aligns with local voltage standards.
2. Identifying Different Medela Breast Pump Models
Spotting differences in packaging and control knob structure can be challenging. Therefore, mothers should pay attention to the machine body instead.
The right corner of a Medela breast pump near the adjustment knob will have a circular shape. This circle is formed by series of numbers. Looking at these numbers, you'll notice a large arrow pointing to the month of manufacture. Naturally, on the left and right of the arrow, there are engraved single digits. When put together, you'll see the year of manufacture. This is the most effective and easiest way to identify different generations of Medela pumps in the market.
