Abstract: A toothbrush case comprises mateable case members and an associated pair of filters. Such filters, preferably of the electrostatic type, remove contaminants from air flowing into the case, and therefore allow flow of substantially contaminant-free air through the case between the filters and around a toothbrush as stored within the case. This assists in evaporation of moisture that is present on the toothbrush (particularly the bristles) or on interior surfaces of the case. Contamination of the toothbrush and the bristles thereof is consequently minimized.
