What is the proper way to use an inhaler?

Use a spacer: The easiest way to use an inhaler is with a spacer. You're much more likely to do it correctly. The inhalation for an hfa inhaler is a slow inhalation through the spacer. Dry powder inhalers are used differently, so make sure you review with your doctor or pharmacist the proper way for your inhaler.

Inhaler technique: Here is a link to one of many videos demonstrating proper technique. I prefer that all patients use an aerochamber (spacer) with asthma inhalers. http://www.youtube.com/watch?v=pwby_uasvhq.
