  • Patent number: 11112763
    Abstract: System that monitors and manages a network of smart filtering containers, such as water pitchers with integrated sensors. Measurements are collected from the containers and forwarded to a centralized system, such as an Internet server; data may be analyzed to determine performance modifications or recommendations for selected containers. Centralizing the data enables discovery of patterns and correlations across containers; for example, abnormal measurements from multiple pitchers in an area may suggest contamination of the area's water supply. The centralized system may automatically update settings of containers to optimize their performance. It may send messages to users suggesting different usage patterns or configurations. It may automatically order components such as replacement filters or upgrades.
