CPAP Machine Cleaning and Maintenance Guide

Continuous Positive Airway Pressure (CPAP) therapy is one of the most effective treatments for obstructive sleep apnea. However, many users focus on wearing their CPAP machine every night and forget the importance of regular cleaning and maintenance.

A dirty CPAP machine can harbor bacteria, mold, dust, and allergens that may affect your health and reduce the effectiveness of your therapy.

This complete guide explains how to clean, maintain, and extend the life of your CPAP equipment.
