Sanitization Tips

It is recommended to wipe or wash and dry an item before using the Lumin. It is recommended to clean these items regularly and replace as directed to ensure clean, effective therapy.

Cleaning Tips

The Lumin requires no extensive cleaning or upkeep. Should the aluminum-coated tray requires cleaning, please do so with a soft cloth and do not use abrasive materials that could reduce the overall effectiveness of the Lumin. The body of the Lumin can be wiped with a damp cloth if necessary.

UV Bulb Tips

The bulb included with the Lumin device is designed to last the lifetime of the device. If the bulb does need to be replaced, it can be purchased separately and installed. Grab the base of the bulb in the Lumin device and pull to remove, then insert and push the new bulb into the socket.

Although the Lumin bulb emits no mercury during use, like any other fluorescent bulb there is a trace amount of mercury present in the glass bulb. If the bulb should break, it should be cleaned and handled the same as a regular fluorescent bulb.

Internal Tray Dimensions

The internal tray of the Lumin roughly measures 9 1/2″ L X 6 1/2″ W x 4″H. The manufacturer advises that anything taller than 6″ runs the risk of touching the bulb and interfering with the ability of the device to disinfect. It’s recommended to not attempt to disinfect anything taller than 4″.

Frequently Asked Questions (FAQs)

 Is the Lumin safe?

The Lumin’s design is completely safe because it contains all the UV light used inside the tray and chamber; this proves little or no UV light can escape. There is an automatic shut-off feature if the drawer is opened. This action prevents UV light from going outside of the unit. 

Will the 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. How does the Lumin Work?

From the Lumin user manual:

“Lumin works by emitting high energy light within a narrow spectrum referred to as UV-C. The Lumin relies on a low-pressure, mercury-arc germicidal lamp designed to produce the highest amounts of UV energy – where 90% of energy is generated around 254nm. This light 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 operating rooms, ambulances, emergency service vehicles and other high touch areas.” Why did 3B Medical choose to design a device that uses UV light to sanitize instead of other methods like ozone / activated oxygen?

From the manufacturer in the Lumin user manual:

“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 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 sanitizer, care was taken to find the safest and fastest way to disinfect CPAP accessories. UV-C was by far the best solution.”
