Every machine in the world is prone to wear and tear over the duration of its use, including CPAP machines. The damage can sometimes be detected earlier; however, that is not always the case. Therefore, keeping an eye out on your before changing CPAP supplies over time is essential. As with all machines, sometimes, catching on early to what works and what doesn't, can be a huge advantage. By finding out about the damaged segments of the CPAP machine, they can be replaced early on, reducing the overall CPAP cost significantly & increasing its longevity. If you are wondering how often you should replace your CPAP supplies, you’re at the right place! So, here’s what you need to look out for regarding your CPAP supplies!
1. CPAP Mask (Replace Every 3-6 Months)
Regarding the entire setup, masks play a key role in your sleep. The more comfortable you are, the better sleep you get. Many users continue using old masks, filters, and chin straps without realizing the impact. This is why ensuring these aren’t damaged or worn out is essential. Here’s what you need to check before replacing your CPAP supplies:
- Air leaks even after adjusting the mask
- Visible cracks, discoloration, or wear
- Increased skin irritation or pressure marks
- Difficulty maintaining a proper fit
2. CPAP Mask Cushions/Pillows (Replace Every 1-3 Months)
While the mask itself is important, what also can cause discomfort because of damage is the CPAP mask cushion that comes in contact with your sleep. This includes damage and other things, such as sweat or dust, that cover it over its usage time. So, the signs of damage include:
- Loss of shape or flexibility
- Air leaks despite adjustments
- Red marks, irritation, or soreness on the face
3. CPAP Headgear & Chin Straps (Replace Every 6 Months)
Although the headgear and chin straps are adjustable, they can get worn out over time. With velcro, these tend to lose their strength to hold, or when in the case of buckle, they can get loose over time. Hence, you must look out for:
- Straps lose elasticity and become loose
- Difficulty keeping the mask secure
- Needing frequent readjustment for a snug fit
4. CPAP Tubing (Replace Every 3 Months)
As you use your CPAP regularly, moisture buildup from humidified air creates a damp environment inside the tube, increasing the risk of mold, bacteria, or mineral deposits forming over time. Constant exposure to air pressure fluctuations also strains the tubing, causing it to lose flexibility and durability, making it less effective in delivering consistent airflow.
- Cracks, holes, or tears in the tubing
- Unpleasant odors even after cleaning
- Excessive condensation buildup inside the tube
- Reduced air pressure delivery
5. CPAP Filters (Replace Every Month)
CPAP filters wear out as they continuously trap dust, allergens, and airborne particles, leading to clogging and reduced airflow. Over time, accumulated debris decreases efficiency, making it harder for the machine to deliver clean air. If not replaced regularly, dirty filters can also harbor bacteria and allergens, potentially causing respiratory issues or reducing the effectiveness of CPAP therapy.
- Disposable Filters (Replace Every Month)
- Reusable Filters (Replace Every Month)
o Filters appear clogged, dirty, or discolored
o Increased dust or allergens in your room
o Decreased airflow or stuffiness in the machine
6. CPAP Humidifier Water Chamber (Replace Every 6 Months)
When it comes to the humidifier, the water chamber deteriorates due to constant exposure to heat and moisture, which can cause the plastic to weaken and develop cracks. If tap water is used, mineral deposits accumulate over time, making cleaning difficult and reducing humidifier efficiency. So, you must remember the following before replacing a CPAP machine humidifier.
- Mineral buildup or residue that doesn’t clean off
- Cracks or discoloration in the plastic
- Unpleasant odors or mold growth
7. CPAP Machine (Replace Every 5-7 Years)
While replacing parts can be beneficial to increase their longevity, what also matters is checking in to not only replacing CPAP supplies but also the entire machine itself over time as the machine experiences gradual wear as its internal motor and sensors work continuously to regulate air pressure. For the overall machine, here are the signs to look for:
- Reduced air pressure or inconsistent therapy
- Unusual noises, rattling, or beeping
- Frequent malfunctions or error messages
- Outdated technology that lacks new features
Keeping the above supplies in check will help you not only increase the life span of your CPAP machine but also save you a long time. However, this is not the case every time; sometimes, the costs for replacement and repair can be equivalent to the cost of a new machine. Therefore, cost-checking is essential for these cases.
