How often should I replace CPAP parts?

When was the last time you replaced your CPAP accessories or machine filters? How long has it been since you bought your CPAP machine? Was it not long after your sleep apnea diagnosis? If it’s been five or more years, it might be time to consider a CPAP machine replacement. All of these questions can feel overwhelming to find the answers to at first. 

Believe it or not, to get the most out of your CPAP therapy, manufacturers recommend that you replace certain parts of your setup — or all of it after a certain length of time — to ensure it’s performing at maximum efficiency. Each part has different cleaning and replacement requirements, which is exactly why we’ve put together a guide to help you keep track. 

Quick Overview

CPAP therapy supplies and setups involve a range of parts. If all you need is a speedy reminder, our helpful guide below can help.

Why replace instead of clean?

While regular maintenance and cleaning can extend the longevity of your CPAP parts and accessories, it’s important to remember that wear and tear will naturally occur regardless. If you’ve noticed a decrease in sleep therapy effectiveness, comfort, or signs of weathering, it may be time to replace parts instead of just cleaning them.

These signs are usually noticeable and specific to certain pieces. For example, if you’ve previously had no issues with your mask and have started to find it uncomfortable to wear or feel it leaking, it’s likely time to swap it out for a new one. You can be the most careful person, but if you’ve been using it every night for a year or more, no amount of cleaning can fully fix the damage of time. Your CPAP mask is like clothing that you wear every day (night) for approximately 8 hours. It wears out. You should care for it and consider it like any other item of clothing worn daily.

How often do I need to clean or replace parts?

The good news is that you don’t need a full CPAP machine replacement whenever a part seems to deteriorate or malfunction. You can save yourself money by simply replacing parts of your setup instead. Even though a full machine will need to be eventually swapped out and upgraded to take advantage of new technological advancements, you may find that your old machine becomes obsolete and far less effective than the latest developments after five or more years.

Depending on its type and manufacturer, each piece has a different recommendation* for cleaning and replacement. Let’s examine each one and determine which CPAP replacement parts you may need to update.

Complete Masks

Generally speaking, a complete mask refers to an all-in-one interface. This can include the swivel where the tube connects to the mask, the seal, frame, diffuser, and headgear. Sometimes, you may require a complete CPAP mask replacement.

Signs of wear

• Discolouration, cracking, tearing and persistent dirtiness.
• Warping of the mould.
• Decreased seal effectiveness.
• Exposure to excess dirt and dust.
• Tears or breaks.

Typical replacement time: 6 to 12 months.

Headgear

Your headgear refers to the straps that fasten your mask to your face. These can be made of various materials, such as velcro, to help you achieve the best fit. Different materials can start to show varying levels of wear over time, so it’s best to keep an eye on how your mask fits after extended use and replace this piece as needed.

Signs of wear:

• Stretched or deformed appearance on straps.
• Tears or breaks.
• Reduced velcro effectiveness (if applicable).

Typical replacement time: 6 months.

Short Mask Tubes

This vital part connects to your mask directly and supplies it with pressured air. It’s incredibly important to ensure that your tubes are free of damage. If you notice a leak in your tube, it’s best to get it replaced immediately.

Signs of wear:

• Punctures, tears or breaks.
• Scratches or scuffed markings.
• Damage or wear at the point of connection.
• Discolouration or build-up of dirt.
• Bends that do not rebound into their natural shape.

Typical replacement time: 12 months.

Machine Filters

Every sleep therapy machine comes with filters, which protect the motor of your machine and prevent dust from making its way into your pressurised air. Knowing when it’s time for a CPAP filter replacement is essential to your sleep therapy process. Although it may not seem important, the filter ensures your air pressure is as clean as possible, keeping your lungs clear of dust and other tiny particles.

Signs of wear:

• Discolouration, tears or breaks.
• Signs of excessive debris or dirt buildup.
• Blockages.

Typical replacement time: 3-6 months.

Complete CPAP Machines

No matter how well-made it is, you will eventually need a CPAP machine replacement. Prioritising your health and safety by swapping out your old machine for a new one ensures you can continue to enjoy the long-term benefits of effective sleep therapy.

Signs of wear:

• Discolouration, wear and tear or cracks.
• A change in operational sound; i.e. increased noise levels.
• Unusual pressure variations.
• Reduced therapy effectiveness; i.e. returning symptoms from pre-diagnosis, such as tiredness and snoring.

Typical replacement time — 5 years.
