Obstructive sleep apnea syndrome (OSAS) affects 26% of adults between the ages of 30 and 70 years. If you've been diagnosed with OSAS and you require a CPAP machine, it's vital to keep your machine clean. 


One part of maintenance is to ensure you remove calcium deposits. Read this quick guide to learn how to clean a CPAP machine and breathe easy at night. 


What Causes Calcium Deposits in a CPAP Machine? 

Using non-distilled water in a CPAP machine can cause it to build up calcium deposits. Manufacturers recommend using only distilled water, as non-distilled water can contain contaminants and deposits

Calcium deposits look like a layer of white or greyish grime. 

In addition to using the proper water for your machine, regular maintenance is necessary to keep it clean. If you notice calcium buildup, use these CPAP machine cleaning tips right away. 


How to Clean a CPAP Machine and Remove Calcium Deposits

First, always follow the instructions given by your doctor or the CPAP manufacturer in regards to cleaning and running your machine. 

Clean the machine's water reservoir at least once a week. Don't use bleach, chlorine, moisturizing soaps, or alcohol-based cleaning solutions, as these can damage the equipment or cause irritation. 


Soak It Using Vinegar

When cleaning a CPAP machine with mineral deposits, you'll have to soak the components in a clean basin, such as a sink, with hot water and vinegar. The acetic acid in the vinegar helps to remove the calcium that has built up. Just remember to check if vinegar is safe to use with your device. 

Mix one part vinegar with five parts water. Let the components soak for between fifteen minutes to half an hour prior to rinsing. 

Using a Cleaning Solution

If the vinegar method doesn't remove the calcium deposits, you can also use a cleaning solution. Only use solutions designed for use on CPAP components to ensure you don't damage them. 

Rinse well and let the parts air dry before using them again at night. 


How Often Should You Clean a CPAP Machine? 

You should clean the resevoir at least once a week, though ideally more often. If you've been sick, make sure you clean the components daily. 

You should replace the mask, tubing, and filters every three months, unless you've been sick. If you've been ill, it's a good idea to replace them afterward

It's a good idea to wipe down your mask using a damp towel and mild soap or a CPAP mask cleaning wipe to remove oils, dirt, sweat, and more that can touch your face. 

Always make sure the unit is unplugged before wiping it down or cleaning. 

Disinfect the humidifier using the vinegar and water method every other week. You can avoid calcium deposits by only using distilled water.
