An aerosol medication delivery apparatus includes a fixed volume holding chamber which is constructed to allow for a uniformly mixed, concentrated bolus of medicated aerosol to be delivered with each breath. The device further includes a universal inlet, so that any standard small volume nebulizer, as well as any standard metered dose inhaler (MDI), may be utilized therewith. Also filtration can be added to address contaminated patient air and aerosol. A one-way valve is positioned between the holding chamber and a tee piece for attaching the holding chamber to a patient mouthpiece, to help control the loss of aerosol, and thereby reduce waste. The device is simply constructed of two molded plastic members, which are readily engaged to complete its assembly.
