How do I use the Lumin?

The Lumin is a single button device. It really could not be any easier. First wipe the inside of your mask and cushion with a wipe to remove any physical residue. If cleaning your humidifier water chamber, open the chamber and place in the drawer face up. If cleaning your mask, lay your mask in the drawer face up. Close the drawer and press the button. In 5 minutes the cycle is complete and your mask and water chamber are ready for use.

How often do I need to clean my CPAP accessories?

You should take care to maintain a proper CPAP cleaning schedule for your machine’s accessories. 3B recommends that you clean your CPAP accessories at least twice a week. A quick 5 minute cleaning cycle will ensure that your accessories are ready to use. In addition, always follow the manufacturer’s recommendations for continued care of your equipment to maximize the life of your machine, mask and accessories.

How does Lumin work?

Lumin works by emitting high energy light within a narrow spectrum referred to as UV. The Lumin relies on a high-quality germicidal lamp designed to produce the highest amounts of UV radiation – where 90% of energy is generated around 254nm. This radiation is very close to the peak of the germicidal effectiveness curve of 265nm, the most lethal wave to microorganisms. The dose of UV emitted in one 5 minute cycle is sufficient to kill most bacteria and germs. The use of UV is environmentally friendly, leaves no residue or toxic gases or chemicals. UV systems are currently in use to disinfect ambulances, emergency service vehicles, and other high touch areas. Download White Paper

Which accessories does the Lumin clean? Will Lumin work for my accessories? (compatibility?)

The Lumin will clean any item that can fit in the drawer. It is designed to handle most CPAP masks, hoses and water chambers.

Are there any supplies that need to be reordered?

No. The Lumin requires no replacement supplies whatsoever. The Lumin relies on a special germicidal UV bulb that is rated for 9,000 hours. Considering that the Lumin cycle is only 5 minutes, daily use of the device would require a total of 5.5 hours. In other words, the light source in the Lumin should easily outlast the life of the device and should not require changing. In the event, the bulb is damaged replacement bulbs are available.

Why should I clean my mask and water chamber?

Moisture left in your mask or humidifier becomes a breeding ground for bacteria and germs.

Will Lumin damage my CPAP mask or accessories?

No. While long exposure times to UVC can weaken plastics and silicone, the Lumin cycle time is only 5 minutes. One year of daily use amounts to 30 hours of actual exposure time. In accelerated aging tests, 3B has validated no damage to plastics or silicone in over 150 hours of testing, roughly equivalent to 5 years of daily use.

Why doesn’t the Lumin use Ozone, like other CPAP cleaners?

Because 3B Medical is a manufacturer of CPAP equipment, masks, and accessories, we have a heightened level of commitment and concern for our patients. We did not feel that the safety concerns of ozone being used in the home were being adequately disclosed. Due to the lifestyles of many of our patients, we also had concerns that the two hour wait period in using CPAP equipment might be ignored and harmful ozone inhaled. For that reason, in designing the Lumin, care was taken to find a fast and effective way to clean CPAP masks and accessories.

Does Lumin cause an odor?

UV light has no odor. The vast majority of Lumin customers experience no odor.  If there is an odor it is likely similar to the smell of burnt hair. Household dust is 90% composed of dead skin cells. Skin, like hair, contains a sulfide molecule. UV light kills pathogens by destroying DNA with high energy light. That same process also frees the sulfide molecule in a skin or hair molecule. In other words, Lumin has no odor. However, household dust may cause an odor when disinfected.

What do I do if my device has an odor?

If your unit has an odor please wipe all 4 of the mirrored surfaces in the drawer thoroughly with a damp cloth using Dawn liquid detergent and dry with a paper towel. Run one cycle with the drawer empty and let the device sit overnight. The next day, your unit should have no odor. If you have any questions or comments, please feel free to visit our Support page on our corporate website at or and fill out a Support Ticket or engage with one of our Technical Support techs via live chat or email during regular business hours.

Does Lumin come with a warranty?

Yes, Lumin is backed by 3B Medical’s comprehensive two year warranty.

Is Lumin covered by Medicare or Insurance?

No, at this point in time, neither Medicare nor private insurers are covering cleaning devices for CPAP equipment.

Can I pay for Lumin using an HSA or FSA?

Yes, Lumin is eligible for purchase under both HSA and FSA.

What are the advantages of UV over Ozone cleaning?

There are a number of competitive devices that use ozone. Marketing of these devices typically conceal the use of ozone by referring to it as “activated oxygen”. 3B Medical felt very strongly that use of a ozone was incompatible with use in a home. Safe use of ozone systems require a waiting period of up to 3 hours. By contrast, UV light is fast and effective.

What is the Lumin Bullet

Lumin Bullet is designed to disinfect your CPAP hose.

How does it work?

The Lumin Bullet works with a powerful germicidal LED that emits ultraviolet light. That light is reflected 360° to reach every area of your CPAP hose. The hose interior only requires 1 second of exposure to disinfect harmful germs.

Does it attach to the Lumin?

The Lumin Bullet is a stand alone accessory. The original Lumin device is NOT needed to use the Bullet.

Does it require batteries?

No. The Lumin Bullet works off of a USB charger. Once fully charged the Bullet will glow green, indicating it’s ready to use. Your fully charged Bullet will last up to 30 uses.

Which way do I insert the bullet inside the hose so it stays in place?

The Bullet is designed with magnets inside. When the Bullet is inserted into the hose, “nose” first the correctly situated magnets will “grip” on to the Bullet. Ensuring your hose is stable.

Do I get a price break with the purchase of both the Lumin and Lumin Bullet?

Yes, bundle deals are available.

What is the warranty? and what does it cover?

The Lumin Bullet is covered under warranty for a period of 1 year from purchase. We guarantee your Bullet device to be free from defects for this time period.

How do you clean the Lumin Bullet?

The Lumin Bullet and the outer shell may be wiped with a clean lint free cloth. Please do not submerge parts into water. If extra cleaning is needed a damp cloth and mild soap may be used to remove grime.

How should I store the Lumin Bullet to not run down it’s charge or lose the Bullet component?

Always place the Bullet inside the clamshell case for protection. Close the clasp and store in a dry area. The magnets will “grip” the Bullet and keep it safely inside the casing.

Why should I purchase the Lumin Bullet in addition to the Lumin?

The Lumin device does a fantastic job of surface disinfection. While it will sanitize the hose, many hoses on the market are opaque. The opacity of a hose will affect it’s amount of UV light absorption. The Lumin Bullet works from the inside out, disinfecting those very hard to reach areas.

Is Lumin Bullet compatible with every CPAP hose?

Lumin Bullet is universally compatible for use on most popular CPAP tubing brands. The Lumin Bullet, however, is not compatible with the ResMed ClimateLineAir™  Heated Tube for AirSense™ 10

Why is the blue light blinking?

The UV LED operates at a wavelength that is not visible to the human eye. A second blue indicator light flashes to let you know that the Lumin Bullet is working.
