For home treatment with positive airway pressure, which humidifier care practice is recommended?

• A. Rinsing and air-drying the reservoir
• B. Using only tap water for humidification
• C. Washing the reservoir with bleach
• D. Emptying the water reservoir once per week

Answer: (A)

Regular humidifier reservoir care is essential to prevent microbial growth in home PAP therapy. Rinsing the reservoir and letting it air-dry after each use removes residual moisture and helps ensure no damp environment remains for bacteria, mold, or fungus to grow. Thorough drying is key because any lingering moisture can become a breeding ground for microorganisms that could be inhaled during therapy. Other options miss this critical point: using tap water can leave mineral deposits and contaminants in the reservoir, which can foster buildup and bacteria; washing with bleach is not part of routine daily care and can leave chemical residues or damage parts if not rinsed thoroughly; and emptying the reservoir only once per week doesn't remove the constant moisture and fails to prevent microbial growth.
