How to Clean a Resmed CPAP Water Chamber

The built-in humidifier on ResMed CPAP devices help make sure the air you breath as you sleep is warm and moist. But warm water is a potential breeding ground for bacteria, so it's recommended you clean your CPAP reservoir at least once a week. Cleaning your reservoir only takes a few minutes and requires no special equipment. Regular cleaning can help you avoid respiratory infections that can sometimes afflict CPAP patients.

Instructions

• 1

  Remove air tubing from the air outlet on the humidifier.

• 2

  Remove the humidifier reservoir. On S8 models, this involves depressing a latch at the bottom of the humidifier and pulling it away from the machine. On S9 models, you'll need to lift the lid on the humidifier section and lift the reservoir out.

• 3

  Put a drop or two of mild liquid dish soap into the humidifier through the air outlet.

• 4

  Fill the humidifier about half full of warm water and agitate it gently. Empty the soapy water.

• 5

  Fill the humidifier about half full with clean, warm water, and agitate. Empty the rinse water. Repeat the rinse process until suds no longer form when you agitate the humidifier.

• 6

  Clean away mineral deposits, if necessary. To do this, disassemble the humidifier by lifting the latches on the side and lifting the top half from the bottom half. Remove the mineral deposits using a clean washcloth and a half-and-half solution of vinegar and water. Rinse the humidifier parts well before reassembling.

  Reinstall the humidifier into the CPAP device. On S8 models, push the humidifier into place, making sure the air inlet fits into the outlet gasket on the CPAP machine. Push until the humidifier clicks into place. On S9 models, raise the lid on the humidifier section and lower the reservoir into the chamber.
