Italy's rise in air‑conditioner use fuels indoor air quality concerns

Around 60% of Italian households now have air‑conditioning units, a figure that has doubled since 2013 as record summer temperatures and frequent heatwaves push more people to seek cooling. Researchers from the Italian Society of Environmental Medicine (Sima) and Velux Italia warn that without proper ventilation, the use of air conditioners can lead to a buildup of volatile organic compounds (VOCs) indoors, persisting for many hours and causing respiratory irritation, headaches, fatigue and, with long‑term exposure, more serious respiratory and cardiovascular risks. A study measuring VOC levels in a closed bathroom showed concentrations remained high for about 15 hours, dropping to safe levels only after 40 minutes of natural ventilation or three hours with mechanical ventilation.

At the same time, Brother, a global electronics firm, has introduced a line of evaporative spot coolers for industrial and commercial spaces in Italy. The PureDrive Spot Cooler PD‑7100S and PD‑7105 use water‑based evaporation to lower air temperature locally, offering a lower‑energy, refrigerant‑free alternative to traditional HVAC systems. The devices are portable, can run up to six hours on a single water tank, and aim to reduce energy consumption and environmental impact while providing targeted cooling for workers and equipment in large facilities.

Both developments highlight Italy’s growing need for effective, health‑protective cooling solutions as climate‑driven heat stresses intensify.
