The Micro 510 is the newer version of the Transcend Micro. Both provide the same core CPAP and Auto-CPAP therapy, compact design, 4–20 cmH₂O pressure range, 27 dBA sound rating, and standard 22 mm mask compatibility. The Micro 510 is designed and assembled in the USA using both U.S. and imported components.

The Micro 510 adds several upgrades, including a 3-year warranty instead of 2 years, four color options, a hard-shell travel case, included AirMist™ HME waterless humidification, and a hypoallergenic filter option.

If therapy performance is your primary consideration, both devices provide the same core therapy. If you want the additional accessories, filtration option, colors, and longer warranty, the Micro 510 offers those upgrades.

Yes. The Transcend Micro 510 isn't designed only for vacations or occasional travel—it can also be used as your everyday CPAP, as long as it meets your prescribed therapy needs. It provides both CPAP and Auto-CPAP therapy with a pressure range of 4–20 cmH₂O, the same pressure range used by most full-sized home CPAP machines.

The Micro 510 is rated at 27 dBA and includes the WhisperSoft™ Muffler to help reduce therapy noise. That said, no CPAP is completely silent. Because portable CPAP machines are much smaller than traditional bedside machines, they may sound different, and some people may notice more airflow or machine noise depending on their pressure setting, mask, mask leak, and sleeping environment.

We'd rather set the right expectation: the Micro 510 is designed for quiet operation, but your experience may not sound identical to your full-sized home CPAP.

The Micro 510 delivers CPAP and Auto-CPAP therapy across a 4–20 cmH₂O pressure range while weighing less than half a pound. For many users, that means they can get the therapy they need from a dramatically smaller machine at home or while traveling.

There are differences, however. The Micro 510 uses waterless HME humidification instead of a traditional heated water chamber, and a compact travel CPAP may sound different from a larger bedside device. If there is a particular feature on your current home CPAP that you rely on, our team can help you compare before you buy.

The Micro 510 supports both fixed CPAP and Auto-CPAP therapy from 4–20 cmH₂O. Your device is programmed according to your prescription before use.

If your prescription calls for a different type of therapy or falls outside the Micro 510's supported range, contact your healthcare provider or our team before purchasing to make sure the device is appropriate for your therapy needs.

The 6-foot TransFlex™ hose is included, but a CPAP mask is not included with the standard Micro 510.

The good news is that you don't need a special proprietary mask. If you already have a compatible CPAP mask you like (22 mm connection), there's a good chance you can continue using it.

Most likely. The Transcend Micro 510 works with CPAP masks that use a standard 22 mm connection, giving you the freedom to continue using the nasal, nasal pillow, or full-face CPAP mask that already works for you.

If you're unsure about your particular mask, contact us before ordering and we'll help you check compatibility.

The Micro 510 includes Transcend's AirMist™ HME waterless humidification system. Instead of using a water tank, the HME captures moisture from your exhaled breath and surrounding air and returns moisture as you breathe during therapy. That means there's no reservoir to fill and no distilled water to pack when you travel.

It's important to know that waterless humidification is different from a traditional heated humidifier. If you rely heavily on the warmth or high humidity level of a heated water chamber, the experience may feel different. We want you to know that before making the switch.

The standard Transcend Micro 510 package includes:

• Transcend Micro 510 Auto CPAP
• Hard-shell travel case
• TransFlex™ 6-foot hose
• Hypoallergenic air filter
• WhisperSoft™ Micro Muffler
• AC power adapter
• AirMist™ HME
• Micro 510 user guide

A CPAP mask and PowerAway Battery are not included with the standard device unless they are specifically part of the package or bundle you purchase.

Yes. Transcend pre-programs the Micro 510 based on your prescription, so your therapy settings are configured for you. The device also includes comfort features such as GentleRise™ ramp and AirRelief™ exhalation pressure relief.

Prescribed therapy pressure settings should only be changed by an authorized healthcare provider, equipment supplier, or Transcend. Comfort settings can be managed separately.

The Micro 510 keeps the controls intentionally simple. There are four main buttons on top of the device: Power, Bluetooth, Ramp, and Drying Mode.

• Power: Starts or stops therapy. When the Micro 510 is plugged in and in Standby Mode, the power light glows green. Once therapy is actively running, the indicator lights turn off so they don't create unnecessary light while you sleep.
• Bluetooth: Controls the connection to the optional MySleepDash™ app. A blue light means Bluetooth is enabled but not currently connected, green means your phone is connected, and white means Bluetooth is turned off.
• Ramp: Controls the GentleRise™ comfort feature, which allows therapy to begin at a lower pressure and gradually increase toward your prescribed pressure as you fall asleep. When Auto Ramp is enabled and configured, the Ramp light glows blue while the device is in Standby Mode.
• Drying Mode: Starts a 30-minute low-speed airflow cycle designed to help dry moisture from the hose and connected accessories after therapy. The Drying Mode light glows blue while the cycle is running.

You don't need to manage complicated menus on the machine itself for everyday use. Your Micro 510 arrives programmed to your prescription, and supported comfort settings can also be adjusted through the MySleepDash app.

If multiple lights begin flashing repeatedly, that can indicate an operating error rather than a normal status light. Refer to the Micro 510 User Guide or contact Transcend Client Care for help troubleshooting the device.

Setup is simple once you know the order. The WhisperSoft™ Muffler connects directly to the air outlet on the Micro 510, and the TransFlex™ hose connects to the other end of the muffler. Your CPAP mask connects at the opposite end of the hose.

If you’re using the AirMist™ HME for waterless humidification, it goes between the hose and your mask, close to your face.

So the setup looks like this:

Micro 510 → WhisperSoft Muffler → TransFlex Hose → AirMist HME → CPAP Mask

The AirMist HME is optional, so without it the setup is simply:

Micro 510 → WhisperSoft Muffler → TransFlex Hose → CPAP Mask

No. The Micro 510 does not have an internal battery.

For cordless therapy, you can add the optional Transcend PowerAway™ Battery or choose a bundle that includes it. This gives you the flexibility to use standard wall power when you're at home and battery power when you're traveling, camping, flying, or away from an outlet.

Yes. The Micro 510's AC power supply accepts 100–240 VAC, 50–60 Hz, making it suitable for use in many countries. Depending on your destination, you may still need the appropriate plug adapter for the local wall outlet.

If you're traveling internationally with the PowerAway Battery, check your airline's current lithium-ion battery rules before departure.

The optional PowerAway Battery can also be used as backup power. When your Micro is connected to the PowerAway Battery and the battery is connected to wall power, the battery can take over if household electricity is interrupted.

Because the Micro 510 does not contain an internal battery, you need the PowerAway Battery connected if you want this type of backup protection.

Yes. The Transcend Micro 510 is FAA compliant for in-flight use. Its compact size also makes it easy to carry while traveling.

Airline policies can vary, especially for using medical equipment or batteries onboard, so we recommend confirming your airline's requirements before your trip.

Yes. The Micro 510's AC power supply accepts 100–240 VAC, 50–60 Hz, making it suitable for use in many countries. Depending on your destination, you may still need the appropriate plug adapter for the local wall outlet.

If you're traveling internationally with the PowerAway Battery, check your airline's current lithium-ion battery rules before departure.

Yes. For off-grid trips, the PowerAway Battery can be recharged with Transcend’s compatible Sun-Watt solar panel charging option. That can be especially useful for camping, remote travel, or other situations where traditional power isn’t readily available.

The Sun-Watt solar panel charges the PowerAway Battery; it is not a substitute for the PowerAway Battery itself.

Yes. A valid CPAP prescription is required to purchase the Micro 510 in the United States.

If you already have a prescription, you can provide it post purchase. If you don't have a copy available, our Medical Records team can help you work through the next steps and, when applicable, help obtain the necessary prescription information from your healthcare provider.

Transcend does not bill insurance directly. You can purchase the Micro 510 from us and then seek reimbursement from your insurance provider if your plan allows it. We can provide documentation to help support your reimbursement request, but coverage and reimbursement amounts depend on your individual insurance plan.

HSA and FSA funds can also generally be used for eligible CPAP machines, accessories, and replacement parts. If you're unsure whether your particular HSA or FSA will cover your purchase, check with your plan administrator before ordering.

Yes. Flexible payment options are available for qualifying purchases, allowing you to spread the cost over time instead of paying the entire amount upfront. Available payment options will be shown during checkout.

This is one area where we want to be especially clear before you purchase.

Transcend's standard return policy allows new and unopened products to be returned within the applicable 30-day return window. CPAP machines must be in brand-new, unused condition and include the original packaging, materials, accessories, and included items to qualify for a standard return.

Because a CPAP is a medical device, we encourage you to contact us with any questions about therapy type, humidification, noise, mask compatibility, or other features before opening and using your device if you're unsure whether the Micro 510 is right for you.

Yes. The Micro 510 connects with the MySleepDash™ app on compatible Apple and Android devices, but the app is completely optional and not required for the device to function or deliver therapy. The device will work fully on its own without any app connection.

If you choose to use it, MySleepDash allows you to monitor therapy information, review leak summaries, track therapy hours, and access compliance data.

The app also gives you access to supported comfort settings such as GentleRise™ and AirRelief™.

The Micro 510 is designed to keep everyday maintenance relatively simple. It includes a 30-minute Drying Mode that helps clear moisture from the connected hose and accessories after therapy. Transcend recommends running Drying Mode after each therapy session.

Like any CPAP system, the hose, mask, filters, HME cartridges, and other accessories still need appropriate cleaning and replacement. Follow the Micro 510 user guide for the recommended care and replacement schedule.

The Transcend Micro 510 comes with a 3-year warranty from the date of purchase. The optional PowerAway Battery has its own 1-year warranty.

Our Client Care team is also available if you experience an issue or need help troubleshooting your device.
