Why Resupply Matters for Your Therapy
Your CPAP supplies aren't meant to last forever. The mask cushion that seals against your face, the tubing that carries air, the filters that clean what you breathe—all of these wear out gradually.
When supplies wear out:
- Mask seals become less effective (more air leaks)
- Tubing develops tiny tears (reduced air delivery)
- Filters get clogged (harder for your machine to work)
- Headgear stretches out (harder to maintain good fit)
Fresh supplies help your therapy work better. And the good news? Your insurance covers replacements on a regular schedule.
Your Insurance Replacement Schedule
Here's when you're typically eligible for new supplies:
| Supply Item | How Often | Why It Matters |
|---|---|---|
| Mask cushion/pillows | Every 1-2 months | Direct skin contact wears material quickly |
| Full face mask | Every 3 months | Complete mask with frame and cushion |
| Nasal mask | Every 3 months | Complete mask with frame and cushion |
| Tubing | Every 3 months | Condensation and handling create wear |
| Disposable filters | Monthly | These trap dust and should be replaced frequently |
| Reusable filters | Every 6 months | These need occasional replacement too |
| Headgear | Every 6 months | Elastic stretches with use |
| Humidifier chamber | Every 6 months | Mineral buildup affects performance |
Note: These are standard Medicare schedules. Your commercial insurance may have slightly different rules. If you're not sure about your specific coverage, ask your provider or check with your insurance company.

How to Know When You're Eligible
There are several ways to find out when you can order new supplies:
Check your patient portal:
If your CPAP provider has an online portal, log in to see your eligibility status. Many portals show which items you can order right now.
Look at your last order date:
If you ordered a mask 3 months ago, you're probably eligible for a new one now. Keep track of when you last received supplies.
Wait for your provider to contact you:
Most good CPAP providers track your eligibility and reach out when it's time to reorder. You might get a text, email, or phone call.
Call and ask:
If you're not sure, just call your provider. They can look up your eligibility and let you know what's available.
For more on using your patient portal, see [Your Patient Portal Guide](/blog/your-patient-portal-complete-guide).
Why Fresh Supplies Matter
Some patients wonder, "My supplies still work—why replace them?"
Here's what happens as supplies age:
Mask cushions (after 1-2 months):
The silicone softens and doesn't spring back like it used to. This causes more air leaks, which can dry out your nose and mouth, make noise that bothers your partner, and reduce the effectiveness of your therapy.
Tubing (after 3 months):
Tiny cracks develop from bending and handling. You can't see them, but they can affect air pressure. Plus, old tubing is harder to keep clean.
Filters (monthly):
A dirty filter makes your machine work harder, uses more energy, and potentially shortens the life of your device. Fresh filters keep everything running smoothly.
Headgear (after 6 months):
Stretched headgear means you tighten the straps more to get a good seal. Over-tight straps cause pressure marks on your face and can make your mask uncomfortable.
Think of it like contact lenses or toothbrushes—they still "work" past their recommended replacement date, but they work better when they're fresh.
How to Order Supplies
Ordering is usually straightforward:
Option 1: Respond to your provider's outreach
When they contact you about resupply, simply confirm you want to order. Many providers make this as easy as replying "YES" to a text.
Option 2: Order through your patient portal
Log in, check what's eligible, and place your order with a few clicks.
Option 3: Call your provider
They can take your order over the phone and answer any questions.
Option 4: Visit the office
If you prefer face-to-face, you can stop by and pick up supplies or have them ordered for delivery.
For most patients, supplies ship directly to your home. You shouldn't need to do anything complicated—your provider handles the insurance paperwork.

What It Costs
In most cases, your out-of-pocket cost is minimal or zero:
If you have Medicare:
After meeting your deductible, Medicare typically covers 80% of allowed amounts. If you have a Medigap policy, it may cover the remaining 20%.
If you have commercial insurance:
This varies by plan. Many plans cover supplies with low or no copay. Your provider can tell you your specific costs before you order.
What to ask:
- "What will my out-of-pocket cost be for these supplies?"
- "Has my eligibility been verified?"
- "Are there any coverage issues I should know about?"
Don't let cost concerns stop you from asking. Many patients are surprised to find that supplies cost them little or nothing after insurance.
Setting Up Auto-Resupply
Some providers offer automatic resupply programs:
How it works:
- Your provider tracks your eligibility
- When you're eligible, they contact you for confirmation
- With your approval, supplies ship automatically
- You always have fresh equipment
Benefits:
- Never forget to reorder
- No hassle of tracking dates yourself
- Consistent fresh supplies
You stay in control:
Good auto-resupply programs always confirm with you before shipping. You can skip, delay, or cancel anytime.
Ask your provider if they offer this service.
Common Resupply Questions
"I don't think I need new supplies that often."
You might not notice gradual wear, but it affects your therapy. Try this: when you get new supplies, compare them to your old ones. The difference is usually obvious, especially with mask cushions.
"I'm worried about getting too many supplies I won't use."
You don't have to order everything you're eligible for. If your headgear is still in great shape at 6 months, you can skip that item. But most supplies benefit from regular replacement.
"My insurance denied my supply order. What do I do?"
Talk to your provider. Common reasons for denial include missing documentation or ordering too early. Your provider can often resolve these issues or help you appeal.
"Can I order from someone other than my CPAP provider?"
Technically yes, but be careful. Some online suppliers don't verify insurance properly or may ship lower-quality products. Your provider knows your specific equipment and can ensure you get the right supplies.
Keeping Track
Here's a simple way to track your supplies:
On your phone or calendar:
Set reminders for when you're likely eligible (30 days for cushions, 90 days for mask/tubing, etc.)
With your provider:
Ask about their notification system—most will text, email, or call when you're eligible.
In your portal:
Check your eligibility status whenever you think about your supplies.
The Bottom Line
You're paying for insurance coverage that includes supply replacement—use it. Fresh supplies help you:
- Sleep better with fewer leaks
- Stay more comfortable
- Keep your equipment in good condition
- Maintain effective therapy
When your provider reaches out about resupply, it's because they want to help you succeed with your therapy. Taking advantage of your benefits is simply good self-care.
