• The majority of patients have poor inhaler technique, with the ability to coordinate actuation with inhalation being one of the most common errors.1,2
  • Despite this, many adults do not use spacers for the delivery of inhaler medication, especially while on the go.
  • Potential reasons for not using spacers include portability and appearance
  • The aim of this usability/preference study was to understand patient perceptions of two portable spacer devices compared to the metered dose inhaler (MDI) when used alone.


The prototype AeroChamber2go* spacer device was preferred by patients compared to the A2A† spacer and provides a good option for patients currently using the Metered Dose Inhaler without a spacer while on-the-go.
