How to clean CPAP equipment: the schedule that matters and the gadgets that don't

Part of the series: The Complete CPAP Guide

Mild soap, warm water, and a drying rack outperform most of what's marketed at CPAP owners. What the FDA actually says about ozone and UV sanitizers.

The unglamorous truth first: CPAP hygiene is a soap-and-water discipline, not an equipment category. Daily-ish, the mask cushion gets a quick wash or CPAP wipe — skin oils are what degrade the seal. Weekly, the mask, tubing, and humidifier chamber get mild soap, warm water, a thorough rinse, and air-drying out of direct sunlight. The machine's intake filter gets rinsed or replaced per the manual. Distilled water in the humidifier, always — minerals scale the chamber and shorten its life.

On sanitizing machines, we owe you the straight version because we sell them: the FDA has not authorized any ozone or UV device for cleaning CPAP equipment, and its guidance is blunt — most CPAP accessories can be cleaned with mild soap and water, and the agency has received reports of respiratory irritation associated with ozone-based cleaning. Ozone in particular can also age plastics and silicone faster.

Where does that leave sanitizers? As a convenience some owners value — no disassembly, no drying time — used strictly per their manufacturer's instructions, on top of (not instead of) the soap-and-water baseline, with enough post-cycle airing time if the device uses ozone. What they are not is a health requirement: a clean, dry, soap-washed setup is already the standard your equipment's manufacturer designed around.

The consumables schedule is the part that actually moves therapy quality: cushions roughly monthly as the silicone slackens, masks every few months, tubing when it clouds or stiffens, filters per the manual. If your seal has started leaking at pressures that used to hold, the fix is more often a $30 cushion than a new mask — and more often a new mask than a new machine.
