Experimental deposition efficiencies for deposition from laminar flow in fibrous filters containing variable numbers of layers were obtained by Jackiewicz et al (2008). In the work presented here a particular case of their data for deposition onto filters with 1 to 9 layers is analysed in detail. Its dependence on layer depth is shown to be remarkably similar to the dependence on length of diffusive deposition from similar laminar flow in a cylindrical tube of a chosen radius. The observed mean layer deposition is shown to be consistent with theoretical predictions of deposition by diffusion and interception in the standard cell model. A reason for a larger than average deposition on the first layer is that many fibres in that layer remove particles from the initial particle concentration.
