Lumin CPAP Cleaner Review (Is UV Better Than Ozone?)


The Lumin CPAP Cleaner from 3B Medical was launched recently to meet the growing demand from CPAP users for fast and effective disinfecting of their CPAP mask, nebulizer and accessories.

The maintenance-free Lumin utilizes UV light to kill 99% of bacteria on your CPAP equipment in only five minutes, and can be used to disinfect other household items as well (such as toothbrushes, the kids’ small toys or a hearing aid). 

The Lumin, unlike the SoClean, does not use ozone to sanitize.


Keeping Your CPAP Clean

Manufacturers, suppliers, and sleep physicians all recommend regular cleaning of continuous positive airway pressure (CPAP) equipment.

The mask, tubing, and water chamber should be cleaned on a daily (or at least weekly) basis with liquid dish soap and hot water.

In addition, the device’s filter should be replaced every 2 to 4 weeks.

This cleaning standard may be an ideal that not everyone lives up to, which may lead to significant problems:

  • Minerals may accumulate within the water chamber.
  • Mucus may collect in the mask.
  • Germs may be found in the tubing.
  • Mold may grow in moist environments.
  • There may be unpleasant smells.
  • The equipment may appear unhygienic.

The potential risks with unclean equipment could also be direct exposure to bacteria, viruses, and molds, which may raise the possibility of nasty colds, sinus infections, and even pneumonia.

Disinfecting With UV Light

UV light provides rapid, effective inactivation of microorganisms through a physical process, rather than a chemical one.

When bacteria, viruses and protozoa are exposed to the germicidal wavelengths of UV light, they are rendered incapable of reproducing and infecting.

Ultraviolet (UV) light occupies the portion of the electromagnetic spectrum between X-rays and visible light, and is invisible to the human eye. The sun emits ultraviolet light; however, much of it is absorbed by the earth’s ozone layer.

A unique characteristic of UV light is that a specific range of its wavelengths, those between 200 and 300 nanometers (billionths of a meter), are categorized as germicidal – meaning they are capable of inactivating microorganisms, such as bacteria, viruses and protozoa.

When bacteria, viruses and protozoa are exposed to the germicidal wavelengths of UV light, they are rendered incapable of reproducing and infecting.


UV Safety

Arguably, the most important benefit of UV light disinfection is that it’s non-toxic. And unlike harsh chemicals that are sometimes used in cleaning and sanitization products, UV light is environmentally friendly.

UV disinfecting leaves no residue, toxic gases or chemicals. It’s the system used for many food prep applications, and to disinfect ambulances, emergency service vehicles and other high touch areas.

For added safety, the Lumin was engineered with a magnetic switch that only operates when the chamber drawer is fully closed. Opening the drawer will automatically power off the device.


Five Minute Sanitation



It’s This Easy:

  • Put you mask, hose and water chamber in the drawer. 
  • Close the drawer, and press the round power button (the Cycle-On red light will turn on). 
  • After five minutes, you’ll hear a beep, and a green light will indicate that the disinfecting cycle is done.
  • You can remove your equipment and use it right away; no waiting or wiping-off is necessary.


Disinfecting Household Items

The Lumin CPAP Cleaner is a versatile machine:  virtually anything that fits into the drawer of the cleaner can be sanitized in five minutes.

Some items that come to mind are:

  • razors
  • dentures
  • cell phones
  • electric toothbrushes
  • thermometers
  • orthodontic/snoring gear and mouthguards
  • child’s pacifier


Maintenance Free

The Lumin doesn’t require any replacement supplies. Unless your machine becomes damages, you’ll never need to buy new filters or bulbs.

The Lumin’s germicidal UV-C bulb is designed to outlast the life of the machine.  If the bulb is damaged however, low cost replacement bulbs are available from the manufacturer. 


UV vs Ozone Sanitation

When designing the Lumin, 3B Medical CEO Alex Lucio consulted pulmonary physicians, who expressed considerable concern about residual ozone being inhaled by COPD patients.  This can occur when users don’t properly follow the instructions of CPAP cleaners which use activated oxygen for disinfecting.

Even among healthy people, ozone can cause chest pain, coughing, shortness of breath, and throat irritation if inhaled in even low amounts.

Lucio cites the U.S. Food & Drug Administration’s Code of Federal Regulations, which limits residual ozone to 0.05 parts per million. “In order for ozone to be effective as a germicide, it must be present in a concentration far greater than that which can be safely tolerated by man and animals,” states the code.

“Although undesirable physiological effects on the central nervous system, heart, and vision have been reported, the predominant physiological effect of ozone is primary irritation of the mucous membranes. Inhalation of ozone can cause sufficient irritation to the lungs to result in pulmonary edema.”


Lucio says,

“In a sleep lab, [ozone] is fine. Sleep lab employees have protocols and understand how to follow instructions in working with chemicals and gases. But there is a risk that patients won’t follow instructions, such as waiting 2 hours before using their mask. For that reason, we had no choice but to stay clear of ozone. I strongly felt that the other products on the market did not properly disclose and label risks.”


Comparing SoClean to Lumin

This is an excellent video: Juan Carlos, a CPAP user himself, does a thorough job of comparing all aspects of the Lumin and the SoClean CPAP sanitizers, and points out where and how they differ.



Points to Consider

The Lumin will kill all the bacteria and fungi on the surface of items, but will not remove solid debris; if necessary, give them a quick wipe or rinse before placing them in the Lumin.

The Lumin cannot sanitize the insides of your tubing system or nasal pillows, as it only disinfects the outer surface of items.  Ozone, used in the SoClean CPAP Cleaner does flow through the tubing and mask to sterilize those areas.

To clean the aluminum-coated tray of the Lumen of any dirt particles, just wipe it down with a soft damp cloth (don’t use chemicals or abrasives).

Keep the Lumin dry, and out of children’s reach.

Don’t place any items on top of the Lumen.


Lumin Specifications

The Lumin CPAP Cleaner measures 12¼” long by 8½” wide by 7¾” high, and weights 5½ pounds.

It should be stored at temperatures between 0 ̊ to 120 ̊ F / -18 ̊ to 49 ̊ C

Its operating temperature is  20 ̊ to 100 ̊ F / 7 ̊ to 38 ̊ C, with a humidity of up to 93%, non-condensing.
