Abstract
Abstract The portable sink top water conditioner includes couplings for periodically recharging the water filtering and conditioning elements in response to an indicator signal generated as a result of deposition of a predetermined weight of material filtered from the water and retained by the conditioner. Filter elements for maintaining the bacteria count at an acceptable level may be incorporated.
