A heat and moisture exchange filter (HME filter) is routinely placed in the ventilator tubing to ensure that the inhaled air is warm and humidified.

Participants will not cook or handle food. Lung function will be measured using peak expiratory flow (PEF), and cognitive performance will be assessed using validated tests including the Hopkins Verbal Learning Test-Revised and the Processing Speed Index from the WAIS-IV. Airborne particle and gas concentrations in the chamber will be continuously monitored to ensure that exposures remain within levels typical of everyday home cooking.
