    Differences between Spectra S9 Plus vs Ameda Mya

    Type of Pump

    Both the Spectra 9 Plus and Ameda Mya are portable double electric breast pumps. This means that they are great for using while out of the house or away from easy access to a power outlet.

    You don’t need to be out of the house to find a portable breast pump handy though. If you need to be up and about and can’t afford the time to sit down while pumping, a portable pumps might be just what you need.

    That being said, they are perfect for working moms who are trying to express some extra breast milk during the day, or if you need to express a little to increase your milk supply during the day.

    Is Spectra S9 a Hospital Grade Breast Pump?

    A hospital grade breast pump can only be deemed as such if it has been approved by the FDA. They are typically larger than personal breast pumps and pack a good punch in terms of power and suction compared to their counterparts. Neither the Spectra S9 or the Ameda Mya are true hospital grade breast pumps, but they do offer hospital grade strength, as well as being hygienic closed system pumps.

    If you are in the market for a true hospital grade pump for regular daily use, check out the Spectra S2 or Medela Symphony. These pumps are designed to handle the heavy load of long term exclusive pumping or the heavy use that comes from power pumping to increase your milk supply.

    These double electric breast pumps are for personal use and shouldn’t be mistaken for being hospital grade – even if they are branded as hospital-strength breast pumps. They have, however, proven to be increasingly popular due to their petite size and portability.

    Spectra s9 has an adjustable suction up to 300 mmHg compared to the Ameda Mya at 280 mmHg suction strength.

If you’re looking for a portable hospital grade pump, check out the Spectra S1.

    The breast shield size is extremely important and the wrong size could lead to painful and cracked nipples. 

    The flanges that are included with the Spectra S9 are 24 mm which is the size in breast shields that they provide across a range of their pumping products. Extra sizes and replacements are easily available from Spectra Baby USA and Amazon.

    It’s a draw: Spectra and Ameda both give 1 set of 24mm breast flanges as standard with their product.

    It’s a tie: They both have excellent warranties

    Winner: Spectra s9 is lighter and smaller

    Noise Level and Practicality

    We were incredibly happy with the Spectra S9 especially when they combined it with freemie cups to further enhance the idea of being portable and discreet. With the freemie cups, you can pump on the go, at weddings with music playing, and even en route to and at work.

    Ameda Mya is also quiet as it won’t wake the baby however it isn’t as discrete as the Spectra with the Freemie adaptability.

    All breast pumps will make some sound, however the reports and reviews from other users have said that they can express with the Spectra without waking a baby, and where there is some background noise that can disguise the sound of the pump.

    Winner: Spectra S9 is quieter
