ventiloitu

Ventiloitu is a Finnish adjective meaning provided with ventilation, i.e., having an active process of exchanging indoor air with outdoor air. It describes spaces or devices where air movement is facilitated by natural openings or mechanical systems such as fans, ducts, or HVAC equipment. A ventiloitu area aims to maintain indoor air quality by removing moisture, odors, and pollutants and by supplying fresh air.

In everyday use, ventiloitu is common in real estate, architecture, and building services. Examples include ventiloitu asunto or ventiloitu rakennus. The term is closely related to ilmanvaihto (ventilation) and ilmankierto (air circulation). Finnish practice often distinguishes natural (luonnollinen ilmanvaihto) and mechanical (koneellinen ilmanvaihto) ventilation when describing ventilated spaces.

Ventiloida is the verb meaning to ventilate; ventiloitu is the past participle/adjective form. The root ventili- reflects the concept of ventilation and has cognates in other European languages. In professional contexts, ventiloitu status signals that a space has a functioning air-exchange system, though actual performance depends on design, maintenance, and use of the system.
