Filled with sterile water for inhalation, these humidifier systems feature a dual-purpose reservoir with a snap-open trigger, which  makes a round opening for secure attachment of a humidifier adapter (available with Humidifier Systems 002620, AL2702 and also separately). The oxygen pathway is designed to help prevent particulate from reaching oxygen delivery tubing. An audible relief valve warns if the patient's tubing becomes occluded.

• Designed for convenient shelf storage, Compact Humidifier 002620 has a multiangle outlet port that prevents spitting, even at high flow rates, and a small bottle opening that prevents refilling. It includes an adapter and a 4psi pressure-relief valve with alarm.
