A purifier is best defined as which?

Explanation:
Purification is about taking out unwanted substances to make something clean and safe. A purifier is a device that removes dirt or harmful substances from a substance, usually water or air, to improve quality. This definition fits best because it emphasizes removing contaminants rather than just holding or storing the substance, recording data, or measuring a physiological parameter. The other ideas describe storage, data capture, or measurement, which are not what purification does.
