CPAP Cleaning & Maintenance Schedule — The Complete RRT Guide

By Yash, RRT — Licensed Respiratory Therapist & Owner, MyRespCo

Your CPAP machine is a medical device. Like any medical device, it requires regular maintenance to perform consistently. Patients who clean and maintain their equipment properly have better seal quality, lower mask leak, fewer skin issues, and longer machine life. Here's the exact maintenance schedule I give to patients in clinical practice.

Daily Maintenance (Every Morning After Use)

• Wipe the mask cushion — use a CPAP mask wipe or damp cloth with mild soap. Remove facial oils that accumulate overnight and degrade the silicone seal.
• Empty the humidifier water chamber — do not leave standing water in the chamber between sessions. Stagnant water is a breeding ground for bacteria and mold.
• Leave equipment to air dry — disconnect tubing and mask components and hang or lay flat to dry completely before next use.

Weekly Maintenance (Once Per Week)

• Wash the mask cushion and frame — warm water and fragrance-free mild dish soap. Rinse thoroughly. Air dry completely.
• Wash the headgear — same process. Headgear stretches over time; if it has lost its elasticity, replace it.
• Wash the humidifier water chamber — soak in a solution of 1 part white vinegar to 5 parts water for 30 minutes, then rinse thoroughly and air dry.
• Wipe down the CPAP machine exterior — damp cloth only. Never submerge the machine or spray cleaners directly on it.
• Inspect tubing — hold the tube up to light and look for cracks, holes, or discoloration. Replace if any are found.

Monthly Maintenance

• Clean or replace the disposable filter — most machines have a thin white disposable filter and a thicker gray reusable filter. The disposable filter replaces monthly; the gray filter rinses with water and air dries.
• Inspect the mask cushion — if you notice reduced flexibility, visible wear, or persistent leak after cleaning, replace the cushion regardless of elapsed time.
• Review your myAir or SD card data — check for any trend in rising AHI or mask leak that might indicate equipment degradation.

Every 3–6 Months

• Replace the mask cushion — even if it looks fine, silicone degrades. Proactive replacement prevents gradual seal quality loss.
• Replace the tubing — standard CPAP tubing degrades over time. A fresh tube eliminates one potential leak source.
• Replace disposable filters — on schedule or whenever visibly gray or dirty.

Annually

• Consider a full mask replacement — frame, headgear, and cushion. Annual replacement of the full mask assembly resets all the wear-related seal issues at once.
• Schedule an RT Consultation — an annual therapy data review with a Licensed Respiratory Therapist catches drift in settings, identifies pressure range issues, and confirms your therapy is still optimally configured for your current condition.

What Not to Do

• Never use bleach, alcohol, or scented soaps on mask components — degrades silicone and can cause skin reactions
• Never use a dishwasher for mask parts unless manufacturer specifically approves it
• Never use tap water in your humidifier if it has high mineral content — use distilled water to prevent mineral buildup
• Never skip cleaning because you “don’t see anything wrong” — bacterial biofilm develops invisibly
