This is information I received directly from Philips re the Innospire Go...hope it helps someone:

"If you rely on it heavily, then I would have a backup nebulizer system. The saline is what causes problems due to corrosion of the metal components in the device and the very fine mist gets into it. You have to strictly follow the cleaning regime as per the instructions to ensure it works over time (see attached).

Also ensure when you are charging up the battery, once it is fully charged after a few hours, unplug it so that it won’t reduce the life of the battery. Some people leave it on charge overnight and this isn’t a good idea.

Lastly, try not to cough into the device while nebulizing as this promotes warm air within and then condensation and the liquid drips down the back of the device (for some patients, not all). When this happens with saline, the back of the device where the power cord plugs into starts to corrode.

The device has a 2 year warranty so if anything goes wrong we will replace so you have 2 years to cover yourself even though we have delisted the device. Keep your receipt to ensure the warranty replacement will be honoured."
