Procare Inhaler Spacer Chamber is an anti-static holding container that is to be used with a Metered Dose Inhaler (MDI) also known as a puffer. When the inhaler is pressed, the spacer holds the medicine in its container and breaks it into smaller droplets making it easier to take asthma or COPD medication. It minimizes the chances of medicines ending up in your mouth or throat and helps maximum medicines get deep in your lungs. The Inhaler Spacer by Procare has a whistling sound that alerts you if the inhaling process is too slow or fast. For kids, we also offer the Spacer with a Pediatric Mask, and if you prefer to use it without a mask we have the conventional Inhaler Spacer as well.
