These devices are as portable and as easy to use as the pMDIs but the aerosol is produced by the inhalation of the patient, which © Woodhead Publishing Limited, 2013 26 Inhaler devices effectively reduces co-ordination issues. A further benefit of the DPI is that it does not require a propellant (Harris, 2008). From the vast number of studies performed on the particle size of inhalation aerosols, Frijlink and de Boer indicate that the optimal aerodynamic diameter for DPIs, that are operated at inspiratory peak flow rates between 30 and 150 L/min (Frijlink and de Boer, 2005), lies somewhere in the range between 1 and 5 mm.
