A spacer is always recommended while using puffer for people having difficulty in breath coordination, regardless whether using puffer daily or during an emergency. A spacer is a clear plastic container shaped like a tube and an insert cavity for an inhaler / puff at the other. Spacers help to get medication such as in respiratory ailments into your lungs. The medication is ‘fired’ from the puffer into the spacer device and is then inhaled gradually. Helps deeper reach, avoids wastage. SUITABLE FOR CHILDREN.
