Abstract
A droplet bandpass filter and method of modifying droplet size distribution of a population of droplets suspended in a gas. Droplets suspended in a gas are flowed through a bandpass filter having a tortuous pathway which comprises at least one impactor region located at a position adjacent to a flow direction change. Larger droplets impact at the impactor region while smaller droplets remain suspended in the gas and flow in the first output direction. Other flow restrictors may advantageously be included in the tortuous pathway. The filter is particularly useful in delivering sterilant aerosols (e.g. peroxides) with reduced populations of large droplets.
