An appliance for delivering agent. The agent-delivery appliance includes an agent-releasing mechanism, an air-moving device that generates a flow of air moving from upstream to downstream, and at least one filter. The agent-releasing mechanism includes a chamber configured to release agent into the flow of air generated by the air-moving device. The chamber includes multiple openings, one of which is configured to provide air loaded with agent from the chamber to a first location within the flow of air generated by the air-moving device. At least one filter is located upstream from the first location within the flow of air generated by the air-moving device.
