A purifier actively extracts and eliminates harmful pollutants, toxic gases, chemical vapors, and microscopic particulate matter from a specific medium, such as indoor air or household water. An air purifier draws in ambient room air using an internal fan, forces it through a multi-stage filtration matrix consisting of a pre-filter, a true HEPA filter, and an activated carbon bed, and then exhausts clean, purified air back into the room. This process traps fine dust, pollen, pet dander, mold spores, and smoke particles permanently. Similarly, a water purifier forces contaminated tap water through specialized membranes and carbon media to strip away heavy metals, chemicals, and disease-causing pathogens before storage.
