Use of a spacer is a simple and effective way to help improve the use of your inhaler. Spacers help to ensure that your medicine reaches your lungs where it’s needed and limits the amount that ends up in the back of the throat.1
People who use a valved holding chamber (VHC) such as AeroChamber Plus* Flow-Vu* chamber, with their inhaler have better control of their respiratory symptoms.2
To improve drug delivery, respiratory guidelines recommend the use of chambers when using metered dose inhalers or puffers in people of all ages.3,4
Did you know that up to 80% of people have incorrect inhaler technique and the majority do not realize they have a problem?1

Frequently Asked Questions
A spacer is a device that is placed on the mouthpiece of your inhaler. When used, a spacer creates "space" between your mouth and the medicine holding the medication inside, allowing you more time to inhale your medicine.
Spacers help by making it easier to inhale your medication and helping to ensure the inhaler medication is delivered to your lungs, where it is needed.2
The AeroChamber Plus* Flow-Vu* spacer can be used with all commonly prescribed metered dose inhalers (puffers). In fact, not only does it work with all MDI’s, the AeroChamber* brand of spacers is the most recommended by leading metered dose inhaler pharmaceutical companies.
The AeroChamber Plus* Flow-Vu* spacer can also be used with soft mist inhalers if required.
The AeroChamber2go* spacer is designed specifically for use on the go and can be used with most metered dose inhalers. Use may cause premature wear or damage to the device. The AeroChamber2go* chamber has not been designed for use with Soft Mist Inhalers.1
The majority of adults do not use their inhalers properly. Up to 80% of people have poor inhaler technique which can lead to asthma attacks and poor outcomes.1
Spacers help by making it easier to inhale your medication and helping to ensure the inhaler medication is delivered to your lungs, where it is needed.2
