ResMed Comfort manual Periodically, Remove air filter box at rear of flow generator

Periodically

All items of the mask and air tubing system are subject to normal wear and tear and may eventually need to be replaced. Check periodically for excessive wear in these items.

1When dirty, remove the headgear and wash it in warm water using a mild detergent (about every two weeks). Rinse thoroughly and drip dry. Do not use bleach.

2Replace the forehead pads if they are dirty or worn (every three to six months).

3Clean the exterior of the flow generator when necessary with a damp cloth, using a mild detergent. Make sure the flow generator is unplugged before cleaning, and make sure it is dry before plugging in again.

Replacing the air filter

4The air filter box at the rear of the flow generator contains two replace- able air filter strips. Check the air filter strips periodically and replace them when they become noticeably dirty (about every six months, or more often if your unit is in a dusty environment).

•press down firmly on the center of the filter box between the two moulded arrows,

•slide out the box.

CAUTION:	•	Do not immerse the unit or power cord in water as serious
		damage could result.
	•	Do not use bleach, alcohol-based or chlorine-based
		solutions to clean the flow generator, nasal cushion, mask
		or air tubing. These solutions may cause hardening and
		reduce the life of the products.
	•	Do not wash or dry the mask frame in a temperature
		above 80°C (175°F). Exposure to higher temperatures
		may reduce the life of the product.
