#self-purification

• To self-clean — To automatically or autonomously eliminate or clean one's own impurities, residues, deposits, or harmful substances through its own built-in constructive, chemical, technological, or biological mechanisms, without requiring direct manual intervention from an external factor. In technology, it describes a smart feature of household or industrial appliances, whereas in ecology it refers to the natural capacity of an aquatic or forest ecosystem to neutralize pollutants.
• Self-cleaning — The act of self-cleaning and its result; a technological feature, automated cycle, or structural ecological process through which an appliance, filter, or natural medium eliminates its accumulated residues and impurities on its own. This property optimizes efficiency, prevents blockages, and extends the lifespan of systems.
• Self-purification — A natural biological, physical, or chemical process by which a polluted body of water, an ecosystem, or a living organism rids itself of toxic substances, impurities, or pathogens, restoring its initial structural balance without artificial external intervention.
