HELP INFORMATION Frequently Asked Questions

Q. How does Lumin work?

Lumin works by emitting high energy light within a narrow spectrum referred to as UV-C. 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-C emitted in one 5 minute cycle is sufficient to kill most bacteria and mold on a surface. The use of UV-C is environmentally friendly, leaves no residue or toxic gases or chemicals. UV-C systems are currently in use to disinfect ambulances, emergency service vehicles, and other high touch areas. Download White Paper

Q. 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.  The U.S. EPA published a serious warning about the use of ozone in a home environment:

«When inhaled, ozone can damage the lungs. Relatively low amounts can cause chest pain, coughing, shortness of breath and throat irritation. Ozone may also worsen chronic respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections.»

For that reason, in designing the Lumin, care was taken to find the safest and fastest way to disinfect CPAP accessories. UV-C was by far the best solution.

Q. Why should I disinfect my mask and water chamber?

Moisture left in your mask or humidifier becomes a breeding ground for bacteria, germs, and mold. Keeping your CPAP mask and humidifier free of harmful germs and bacteria helps avoid getting sick from a dirty CPAP.

Q. 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-C 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.

Q. 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 disinfecting your humidifier water chamber, open the chamber and place in the drawer face up. If disinfecting 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. Because UV-C disinfection involves light waves, it operates in “line of sight” fashion, only irradiating surfaces within its sightlines. If there is heightened need for disinfection, the mask can be disassembled or a second cycle used after flipping the object over. For general daily use, only one cycle is necessary.

Q. 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.

Q. Which accessories does the Lumin disinfect?

The Lumin will disinfect any item that can fit in the drawer. It is designed to handle most CPAP masks and water chambers. The Lumin is also useful for disinfecting any personal items that fit, including cell phones, hearing aids, oral appliances, etc. 3B Medical is unable to make a marketing claim on disinfection of a hose due to the large variety, shapes and colors of CPAP hoses. Disinfection by UVC depends on optics. In testing with a standard CPAP hoses, sufficient UVC penetrates the hose to offer sanitization and 3B Medical recommends using Lumin twice weekly as part of your CPAP maintenance schedule. Alternatively, the hose is the least expensive component of a CPAP setup and should be changed often. At checkout, add our Ultra Noir Deluxe CPAP hose to your order for only $4.99!

Q. Does Lumin cause an odor?

UVC 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. UVC light kills pathogens by destroying DNA with high energy light. That process also frees the sulfide molecule in a skin or hair molecule.  If your unit has an odor please wash 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. Next day, your unit should have no odor.
