Product Description
ResMed AirFit N20 Nasal CPAP Mask with headgear (standard version, blue accents). The ResMed AirFit™ N20 is a premium nasal CPAP mask designed to provide a gentle, effective, and reliable seal for sleep apnea therapy. Its innovative InfinitySeal™ silicone cushion adapts to various facial contours, fitting 99.4% of different face shapes in studies. This adaptive cushion maintains a secure seal with minimal leaks, even as you move during sleep or use higher pressure settings. The mask’s soft, flexible frame sits below the eyes for an open field of vision, allowing you to comfortably read or watch TV before bed. Plush fabric headgear with magnetic clips provides a secure but easily removable fit, and a quick-release elbow allows convenient detachment from the CPAP hose without removing the entire mask. Overall, the AirFit N20’s user-friendly design helps ensure a comfortable therapy experience throughout the night.
SKU and UPC Codes
The AirFit N20 mask is available in multiple sizes (and a “For Her” variant), each with specific manufacturer part numbers and barcodes:
- Medium (Standard) – SKU 63501, UPC 619498635016
- Large (Standard) – SKU 63502, UPC 619498635023
- Small (Standard) – SKU 63503, UPC 619498635030
-
Small (For Her) – SKU 63500, UPC 619498635009
(The “For Her” version has a lavender-accented headgear and is designed for smaller faces, but uses the same mask design).
Key Features & Benefits
- InfinitySeal™ Cushion: Advanced silicone nasal cushion with specially designed “infinity loops” of varying thickness. This allows the mask to conform to many face shapes and prevents blowouts or leaks, maintaining a secure seal even at high CPAP pressures. In an international study, the AirFit N20’s cushion fit 99% of participants’ faces, reflecting its versatile, adaptive design.
- Soft, Flexible Frame: The frame is soft and padded, resting below the eyes to minimize contact and pressure on the bridge of the nose. This minimalist design offers a wide field of vision so users can wear glasses, read, or watch TV without obstruction. The flexible frame also adjusts naturally to movement during sleep, helping maintain stability and comfort.
- Plush Headgear with Magnetic Clips: The AirFit N20 includes a soft fabric headgear with four adjustment points for a personalized fit. Magnetic clips on the lower straps make it easy to attach or remove the mask – they quickly snap onto the frame and self-align, so you can put the mask on and off in seconds. The magnetic clip design also ensures you preserve your fit settings each time, since you don’t need to re-adjust the top straps when removing the mask.
- Quick-Release Elbow & Quiet Venting: A one-handed quick-release elbow allows you to disconnect the mask from the tubing easily (for example, if you need to get up at night). The elbow swivels 360° and includes a diffuse venting system with tiny exhalation ports. This directs exhaled air away from you and your partner and reduces noise, so the mask vents quietly for a more peaceful sleep.
- Flexible Short Tube: An integrated short tubing (flexi-tube) extends off the mask’s elbow. This lightweight, flexible tube minimizes tugging on the mask by accommodating your movement. It helps maintain the seal as you change positions, giving you greater freedom to move around in bed without disconnecting or causing leaks. The short tube connects to any standard CPAP hose, making the mask easy to use with different machines.
Technical Specifications
- Mask Type: Nasal cushion mask (covers the nose only) for CPAP/BiPAP therapy. It provides a direct airflow to the nostrils and is suitable for users who breathe through the nose.
- Pressure Range: Designed to operate across a wide pressure range of 4 to 30 cm H₂O. This means the mask can maintain an effective seal at common therapy pressures, from low settings up to very high pressure levels.
- Sizes Available: Small, Medium, Large (standard version). The fit is intended to accommodate most adult faces. There is also a “For Her” version (Small cushion with a smaller headgear in violet color) tailored for women or individuals with smaller facial features.
- Materials: Cushion: Silicone; Frame: Polycarbonate/thermoplastic with foam padding; Headgear: Nylon/Spandex blend fabric. All components are latex-free (contains no natural rubber latex) and also DEHP-free and PVC-free, which is important for patient safety. The materials have been tested for biocompatibility.
- HCPCS Insurance Code: A7034 (nasal mask interface) and A7035 (headgear) for those who need insurance reimbursement codes (USA).
- Prescription Required: Yes, the AirFit N20 is a medical device. A valid prescription is required for purchase in the United States, as it is classified as a Class II medical device. (This ensures proper medical oversight for CPAP therapy.)
- Weight: Approximately 2.0–3.5 ounces (mask with headgear assembled). It is lightweight to minimize pressure on the face. (Exact weight varies slightly by size; for example, the frame plus cushion is about 2 ounces.)
- Noise Level: Quiet operation due to diffused vent design. (The mask does not have an official dB noise level rating, but the venting is engineered for minimal noise and draft.)
- Storage & Operating Conditions: Designed to operate in typical ambient temperatures 41°F to 104°F (5°C to 40°C) with relative humidity up to 95% non-condensing. It should be stored in a cool, dry place away from direct sunlight.
- Magnetic Clips: Yes. The headgear uses small magnets for clip attachments. Safety Note: Keep the mask at least 2 inches (50 mm) away from any active medical implant (e.g. pacemaker or defibrillator) to avoid potential magnetic interference. (The magnetic field strength is below 400 mT, but caution is advised for implanted devices.)
Certifications & Approvals
- FDA Approval: The AirFit N20 is FDA-cleared as a safe and effective CPAP mask. (It received 510(k) clearance K161978 in 2016, classified as a non-continuous ventilator headgear/mask, Product Code BZD.) This means it met the U.S. FDA’s requirements for medical devices and can be legally marketed for sleep apnea therapy. In the U.S., it is an Rx-only device.
- International Approvals: The mask carries the CE mark (Conformité Européenne), indicating it meets health, safety, and environmental protection requirements for sale in European Economic Area countries. ResMed masks like the N20 comply with ISO 17510 (oxygen and CPAP mask standard) and other applicable international standards for biocompatibility and performance.
- Health & Safety Certifications: All components are latex-free, important for patients with latex allergies. The product is also BPA-free (no bisphenol-A in mask materials) and phthalate-free (DEHP-free plasticizer). The AirFit N20 has been tested to meet rigorous safety standards for use in home and clinical environments.
- Magnet Safety Notice: Contains magnets in the headgear clips – Contraindicated for patients with certain implants. ResMed has issued safety guidance that patients with pacemakers or metallic implanted devices exercise caution and keep the mask’s magnetic clips at a safe distance (see technical specs above). This mask was included in a 2023 ResMed field safety notice about magnetic interference, and the user instructions were updated accordingly, underscoring its compliance with the latest safety recommendations.
- Environmental Compliance: The device is RoHS compliant (Restriction of Hazardous Substances) as required in many regions, meaning it’s manufactured without harmful levels of substances like lead, mercury, cadmium, etc. It also meets relevant WEEE directives for electronic equipment disposal (though the mask itself is not electronic, the packaging and any connectors adhere to regulations).
Compatibility Details
- Machine Compatibility: The AirFit N20 connects to all standard CPAP and BiPAP machines. It uses the universal 22 mm diameter connector, making it compatible with any brand of PAP device tubing. You can attach it to any standard CPAP hose right out of the box.
- ResMed AirMini Compatibility: If you use the ResMed AirMini travel CPAP, the N20 will work with a special setup pack/adapter. The AirFit N20 mask requires an AirMini N20 connector (sometimes sold as the AirMini N20 Setup Pack) to hook up to the AirMini’s tubing and integrated humidification system. (This adapter replaces the standard elbow with one that fits the AirMini.) Other than that specific case, no adapters are needed for regular CPAP machines.
- Interchangeable Cushions: The N20 frame is part of ResMed’s modular system. It is compatible with the AirTouch N20 memory foam cushion. The AirFit N20 and AirTouch N20 masks share the same frame and headgear; only the cushion material differs (silicone vs memory foam). This means a user can switch to a foam cushion (AirTouch) on the same mask frame if desired, for comfort or skin sensitivity reasons, without changing the entire mask.
- Replacement Parts: The mask’s components (cushion, headgear, elbow, etc.) are modular and replaceable. AirFit N20 cushions and headgear can be swapped as needed. All AirFit N20 parts are cross-compatible within the N20 product line – for example, a Large cushion can attach to a Medium frame, since the frame is universal (only the headgear strap lengths differ slightly by size). This makes it easy to maintain and customize the mask over time.
- Tubing and Accessories: The AirFit N20 comes with a short flexi-tube and standard elbow. It can connect to any standard CPAP tubing (hose), including slimline tubes or heated hoses. For using optional accessories like tube management clips or hose lift systems, the mask’s swivel allows free rotation. The mask is also compatible with most CPAP cleaning devices (UV cleaners, ozone cleaners, etc., though ResMed recommends simple soap-and-water cleaning as per the user guide).

Can I buy a CPAP machine without a prescription?
In the United States, under federal law, CPAP machines are classified as Class II medical devices by the FDA. As such, they require a prescription from a licensed healthcare provider for purchase. This classification is in place because CPAP therapy is considered a medical treatment that needs to be customized for each patient's condition and safety.
A prescription ensures that your treatment is appropriate and monitored by a healthcare professional. Most suppliers, including USA Medical Supply, will not ship a CPAP machine without first receiving a valid prescription. You can submit your prescription through the following methods:
- Text: (413) 200-4191
- Email: info@usamedicalsupply.com
- Fax: (413) 732-2238
This requirement ensures compliance with federal regulations and guarantees you receive the correct equipment and pressure settings.
Do you accept insurance?
No, and we are not contracted with any provider. We do provide a Universal Claim Form that you can download [here] if you wish to try and get reimbursed yourself.
Insurance billing using a Universal Claim Form (UCF) involves submitting a standardized document to your insurance provider to request reimbursement for medical expenses. However, it is not guaranteed that you will be reimbursed, and we are not implying that you will be. It is important to check with your insurance provider to understand your coverage and eligibility for reimbursement, especially for durable medical equipment (DME) like CPAP machines and supplies.
Here’s how the process typically works:
1. Obtain a Universal Claim Form
The UCF is usually provided by your insurance company or available on their website. The form includes sections to detail the medical services or products you've received, such as CPAP supplies, and what you're seeking reimbursement for.
2. Complete the Form
- Personal Information: Enter your personal details, including your name, insurance policy number, and contact information.
- Provider Information: Include details of the healthcare provider or supplier (such as USA Medical Supply), like their name, address, and tax identification number (TIN).
- Service Details: Provide specific information about the medical service or product. For CPAP equipment, this might include the model number, date of purchase, and a description of the equipment (e.g., CPAP machine, mask, tubing).
- Cost and Charges: Indicate the total cost, including what you've already paid out-of-pocket.
3. Attach Supporting Documentation
- Receipts: Attach copies of receipts for the medical service or product you've purchased.
- Prescription: If required, include a copy of the prescription from your healthcare provider for the CPAP equipment.
- Explanation of Benefits (EOB): If your insurance company has already processed part of the claim, include any EOB documents that detail what they have paid and what remains your responsibility.
4. Submit the Claim Form
Send the completed form and all supporting documentation to the address provided by your insurance company. Some insurers may allow you to submit the form electronically, while others may require it to be mailed.
5. Review and Processing
Once submitted, your insurance company will review the claim and determine the amount of reimbursement based on your policy’s coverage for durable medical equipment (DME), such as CPAP machines and supplies. The insurer may contact you or the supplier if more information is needed.
6. Receive Reimbursement
After approval, the insurance company will send you a reimbursement check or direct deposit for the amount they cover, minus any deductibles or co-payments.
Things to Note:
- Coverage Varies: Insurance policies differ in their coverage for DME, so check with your provider to understand your benefits.
- Out-of-Network Providers: If your supplier is out-of-network, you might receive partial or no reimbursement.
- Time Limit: Ensure you submit the claim within the time frame allowed by your insurance provider, as delays can result in denial.
Please remember, reimbursement is not guaranteed. You need to verify all details with your insurance provider.
Additionally, we do accept HSA/FSA payments, which you may be able to use to cover the cost of CPAP equipment and supplies.
Replacement Schedule for CPAP Supplies?
To maintain effective therapy, it’s essential to replace certain CPAP components regularly:
- Mask Cushions: Every 1-3 months
- Tubing: Every 6-12 months
- Filters: Every 1-3 months
- Headgear: Every 6 months These recommendations ensure your equipment stays in optimal condition and your therapy remains effective.
How to Clean and Maintain CPAP Equipment?
Cleaning your CPAP equipment regularly is crucial for effective therapy and hygiene:
- CPAP Mask and Tubing: Wash weekly with warm water and mild detergent. Let it air dry completely before use.
- Humidifier Chamber: Clean once a week with mild soap and warm water, and replace it every 6 months.
- CPAP Machine Exterior: Wipe down weekly with a dry, non-abrasive cloth. Avoid using ozone-based cleaning devices as they may damage your machine and void warranties.
Differences Between CPAP, APAP, and BiLevel?
- CPAP (Continuous Positive Airway Pressure) delivers a fixed pressure throughout the night.
- APAP (Auto-Adjusting Positive Airway Pressure) automatically adjusts pressure based on your breathing patterns.
- BiPAP (Bi-Level Positive Airway Pressure) provides two different pressure levels — one for inhalation and a lower one for exhalation. BiPAP is typically recommended for users with specific needs or those who find CPAP uncomfortable.
How to Choose a CPAP Mask?
Choosing the right mask is key for comfort and therapy compliance:
- Full Face Mask: Best for mouth breathers or those with nasal congestion.
- Nasal Mask: Ideal for those who breathe through their nose and move around during sleep.
- Nasal Pillow Mask: Great for users who prefer minimal contact with their face. If unsure, our customer support can guide you through finding the best option based on your preferences.
Traveling with a CPAP Machine?
CPAP machines are FAA-approved and can be carried as a medical device during air travel. We do Sell Travel Models.Our Travel Models are compact enough to use during flights. Consider investing in a portable battery for convenience if you frequently travel.
How Do Heated and Non-Heated Tubing Differ?
- Heated Tubing: Helps prevent condensation buildup by maintaining consistent temperature from the humidifier to your airway. Also they have an anti-microbial effect by preventing condensation from building in the tubing.
- Non-Heated Tubing: More affordable, lighter, and suitable if you don’t experience condensation issues. It’s compatible with most CPAP machines and masks.
What are the Signs of Sleep Apnea?
Common signs of sleep apnea include:
- Loud snoring
- Gasping or choking during sleep
- Daytime fatigue
- Morning headaches If you experience these symptoms, consult a healthcare provider for a sleep study to diagnose sleep apnea.
How Do I Prevent Bloating or Excess Gas When Using CPAP?
If you experience bloating, elevate your head while sleeping to help reduce the swallowing of air. Persistent issues should be discussed with your doctor, who may recommend adjusting the pressure settings or trying a BiLevel machine.
