puhdistuva
Puhdistuva is a Finnish present participle form derived from the verb puhdistua, meaning to cleanse or purify. In Finnish grammar, participles in the -va/-vä family function as adjectives that describe ongoing actions or states. Puhdistuva specifically denotes something that is being cleansed or is in the process of cleansing. It is typically used attributively in noun phrases, for example puhdistuva prosessi (a cleansing process), puhdistuva vesi (water undergoing purification) or puhdistuva aine (a cleansing agent in a reflexive sense). It is worth noting the closely related participle puhdistava, which is derived from the transitive puhdistaa and describes something that performs cleansing or has cleansing properties, as in puhdistava vaikutus or puhdistava aine.
In usage, puhdistuva appears mainly in technical, scientific, or descriptive contexts to name processes and states
