The BMC Resmart G2S A20 with an integrated humidifier that provides moisture in the air during therapy based on the surrounding temperature and atmospheric humidity. The integrated humidifier is easy to fill and clean.

DO NOT attempt to transport the Resmart G2S A20 with water in the humidifier tank. The humidifier tank is not sealed and can cause damage or loss to the device by spilling water.

It's important to keep the machine and humidifier clean. While the machine itself may not need much cleaning, except for the occasional wipe down, you may notice the humidifier get dirty quickly, especially if using tap water for the humidifier's water supply.

Tap water has added minerals, fluoride, and impurities, and the quality can vary by locality. As the humidifier adds moisture to therapy air, mineral deposits are left behind, creating a hard, chalky film at the bottom of the tank. This is normal if using tap water.
