- Air filter — A technical device or industrial installation designed to retain impurities, dust, pollen, or other suspended particles in the air, ensuring the purification of the gas stream before it enters a room or an internal combustion engine. In ecology, the term also applies to biological systems for natural atmospheric filtration.
- Air ionizer — An electrical appliance or electronic device designed to produce air ions and enrich the atmosphere of a room with electrically charged particles (especially negative ions). This device typically operates based on high-voltage electrical discharges (Corona effect) or ionic dispersion, serving to purify the air by precipitating dust, pollen, and smoke, and is also used for therapeutic purposes.
- Sanitizer — A device, agent, factor, or substance that performs sanitation, contributing to environmental purification, the elimination of infection sources, or the financial restructuring of an institution.
