Buy CPAP Supplies Online: Masks, Filters, and Tubing — What to Order and When
Direct answer: Yes, you can buy CPAP supplies online without insurance — masks, tubing, filters, and water chambers are all sold at cash prices. Replace disposable filters every 2 to 4 weeks, mask cushions every 2 to 4 weeks, tubing every 3 to 6 months, and the full mask every 3 to 6 months. A full MyRespCo restock — full face mask kit $39.99, nasal mask kit $49.99, and 6ft tubing $20.00 — costs $108.98 before filters, all verified live on November 9, 2026.
When to replace each CPAP supply
| Supply | Replace every | Why it matters |
|---|---|---|
| Disposable filter | 2 to 4 weeks | A clogged filter strains the motor and lets dust into the air path |
| Mask cushion or pillows | 2 to 4 weeks | Silicone loses its seal, leaks rise, therapy pressure drops |
| Tubing | 3 to 6 months | Old tubing cracks, collects moisture, and harbors bacteria |
| Full mask (frame + cushion + headgear) | 3 to 6 months | Headgear stretches, frame fatigues, the seal never sits the same |
| Water chamber | 6 to 12 months, or when cloudy or cracked | Mineral buildup and cracks breed bacteria and leak water |
| Headgear alone | 6 months, or when it will not stay snug | Stretched headgear is the most common cause of a slow leak |
Replacement intervals above follow ResMed's guidance (filter every 1 to 2 weeks or monthly, tubing every 3 to 6 months) and Complete Medical Supply's published schedule (mask 3 to 6 months, tubing 3 to 12 months, cushion 2 to 4 weeks, disposable filters 2 to 4 weeks). Your prescriber or DME may give different intervals — follow theirs if they do.

What comes with a MyRespCo machine, and what does not
Every refurbished machine from MyRespCo ships with a new filter pre-installed, so a new machine order does not need filters on day one. The AirSense 10 at $379.99 includes the machine, humidifier, tubing, power supply, filter, and travel bag — mask sold separately. The S10 Complete Starter Bundle at $429.99 includes the mask and tubing. The Dream Sleep combo at $469.99 includes the machine, humidifier, medium full face mask, slimline tubing, and filters. If you already own a machine, the supplies to keep on hand are a spare mask kit, spare tubing, and a pack of filters.
The 6 checks before you buy CPAP supplies online
- Match the part to your machine: AirSense 10, AirSense 11, and AirCurve 10 all use standard 22mm tubing and standard filters for their model. MyRespCo's 6ft tubing is universal 22mm and fits all major CPAP and BiPAP machines. Filters are model-specific — order the filter made for your machine.
- Prescription: Supplies such as masks, tubing, and filters do not carry the machine's prescription requirement at MyRespCo. A machine order always requires a valid prescription in the United States.
- New, not used: Never buy a used mask, cushion, or water chamber. Masks and chambers touch your airway all night. Buy new, from a seller that states the parts are new.
- Count the full cost: A $39.99 mask kit that includes frame, cushion, headgear, and elbow is cheaper than a $29.99 cushion plus a separate headgear purchase. Compare complete kits, not single parts.
- Shipping speed: MyRespCo ships same day if ordered before 2pm EST, with free US shipping. If your mask tore last night, same-day shipping matters more than a $5 price difference.
- Replacement schedule: Set a reminder for filters every 2 to 4 weeks and tubing every 3 to 6 months. Supplies fail slowly — leaks creep up before you notice them, and therapy quality drops with them.

FAQ
Do I need a prescription to buy CPAP supplies?
No, not for supplies at MyRespCo — masks, tubing, and filters are sold without a prescription requirement. A prescription is required only for the CPAP or BiPAP machine itself. Some sellers require a prescription for complete mask systems, so check before ordering elsewhere.
How often should I replace my CPAP filter?
Every 2 to 4 weeks for disposable filters, per ResMed and Complete Medical Supply guidance. A grey or dusty filter is overdue — replace it immediately.
How often should I replace CPAP tubing?
Every 3 to 6 months. Replace it sooner if it cracks, smells, or collects water that will not dry out.
What is the cheapest way to restock CPAP supplies?
A MyRespCo restock of a full face mask kit ($39.99) plus 6ft tubing ($20.00) is $59.99, with free US shipping and same-day dispatch before 2pm EST. Add the nasal mask kit ($49.99) and the full restock is $108.98.
Do MyRespCo machines come with filters?
Yes. Every refurbished machine ships with a new hypoallergenic filter pre-installed. Order spare filters separately when the first one is due for replacement, about 2 to 4 weeks in.
Can I use any tubing with my AirSense 10 or 11?
Yes, if it is standard 22mm tubing. MyRespCo's 6ft universal tubing fits the AirSense 10, AirSense 11, AirCurve 10, and the Dream Sleep Auto CPAP. Heated ClimateLineAir tubing is model-specific — check the model before ordering heated tubing.
General information only — not medical advice. Whether a buyer needs CPAP, APAP, or BiPAP, which mask type fits, and what pressure settings to use, comes from their prescriber and sleep study, not from a seller or an article.
