How to use SoClean

When and why would I use the prewash?

The neutralizing pre-wash is intended to use prior to the first use of your SoClean or when introducing new equipment to your CPAP cleaning system to wash your CPAP mask, hose and reservoir. The pre-wash is a fragrance-free hypoallergenic cleaning solution. The pre-wash neutralizes any pre-existing odors from detergents, and removes any residue from the manufacturing process.

How do I use the pre-wash?

You should use the pre-wash in the same way that you would use dish soap to wash your CPAP reservoir, hose and mask.

Will the SoClean CPAP cleaner and sanitizer work with my heated humidifier?

Yes, there should be no problem with a heated humidifier, which is standard on most CPAP machines.

What if I do not use a humidifier, can I still use the SoClean?

Yes, the SoClean works with or without out a humidifier. If you do not use a humidifier, the SoClean will sanitize the CPAP hose, mask, and headgear.

Should I use distilled water as my CPAP manufacture suggests, or can I use tap water?

Distilled water should be used to clean your CPAP, as there are sediment and minerals in the tap water.

Will the SoClean work with my heated hose?

Yes, but you will need a heated hose adapter.

How long does the SoClean need to run?

We recommend you run the SoClean CPAP cleaner and sanitizer between 5-10 minutes each day. It comes preset at 7 minutes. If you are running your CPAP machine dry (with no water in the humidifier or no humidifier), then you can cut the time down to between 3-5 minutes. If you are experiencing the smell of oxidation, you may increase cleaning time to 12 minutes for a few weeks.

What size masks fit in the SoClean?

The SoClean chamber has a 5” X 5” opening and is 7” deep. Any CPAP mask under that size will fit.

Can I stop washing my CPAP equipment if I use the SoClean?

Your CPAP equipment is completely sanitized every time you use the SoClean. However, the SoClean will not remove facial oils or dust or other foreign materials. You should hand wash your CPAP equipment with the pre-wash solutions every 5-6 weeks.

Does the SoClean get rid of facial oils on my mask?

The SoClean will inhibit facial oil build-up, but it will not remove the oils. Although the SoClean will sanitize and kill any viruses, bacteria or fungi on your mask, some inert residue can be left behind. You may need to wipe off your mask from time to time, or even use the pre-wash provided.

If I wash my CPAP mask before putting it into the SoClean, does it have to be completely dry?

It is better to run the SoClean when your CPAP mask is completely dry.

Is it better to refill the reservoir before or after the SoClean runs? Does it make a difference?

You can refill your reservoir before or after use with the SoClean – it does not really make a difference.

Will I still need to replace the water in my CPAP while using the SoClean? Or should I just add water as needed?

It really is a personal decision; however, you can be assured that each time you run the SoClean, you are sanitizing the water in the humidifier.

There is an oily residue on my mask. Is my mask deteriorating from ozone, or activated oxygen?

It is probably oily reside as addressed above, not from ozone. The mask should be fine after cleaning.

Cleaning & Sanitizing 

What is activated oxygen?
Activated oxygen is a three atom oxygen molecule. This three atom molecule is a colorless gas with powerful oxidizing properties, formed from oxygen by electrical discharges or ultraviolet light.
Can I keep the SoClean attached permanently to my CPAP machine, or should I detach the SoClean each night and then plug in my CPAP hose?

You should not have to disconnect anything – that is the wonderful thing about the SoClean. Once you have it set up, you can leave it until you have to replace your CPAP hose. In some cases when used with a heated hose adapter, you may have to disconnect the water chamber to fill with water.

Can I position the SoClean on a shelf below my CPAP, or does the SoClean need to be level with my CPAP?

Preferably the SoClean cleaner and sanitizer should be level with your CPAP so the flow is easier, but you can put it on a shelf below your CPAP. You will have enough hose length. If you do put it below your CPAP unit, we ask that you periodically look at the check valve assembly to make sure there is no water in the clear tube, as this can harm you SoClean unit. If you do see water, you should replace the check valve assembly.

Isn’t the small tube under water during cleaning? Or is the reservoir supposed to be dry during cleaning?

If you have water in your reservoir, the tube needs to be submerged. In order to get the activated oxygen to clean the water. However, you can also run the SoClean without water in the reservoir.

Does the small hose that goes into the water chamber affect my CPAP air pressure or act like a leak?

The small hose would have a minimal effect if any on your CPAP machine air pressure. In rare cases, if you have a BI-PAP or A-PAP machine, a heated hose adapter may be required to ensure proper pressure. The small hose does not act like a leak.

How long will the SoClean machine last?

We warranty the SoClean for one year. However, in our testing we simulated running the machine for over 5 years and experienced no issues.

Do I need to replace any SoClean parts?

Yes. Once every six months or so (depending on run times), the check valve and the filter need to be replaced. These items are sold together in a kit; the machine is programmed to tell you when these are needed.

Can I use the SoClean CPAP cleaner and sanitizer with two CPAP machines?

The SoClean is designed to stay connected to one CPAP machine. You can clean two CPAP machines; however, you will need to disconnect and reconnect your CPAP equipment. This would be extremely cumbersome and not recommended.

Are there any studies proving that the SoClean machine works?

Yes. Read more about the study here:

Can I use the SoClean to sanitize anything other than my CPAP equipment?

Only the CPAP mask with the head gear should be placed into the chamber of the SoClean.

When using SoClean, how often should a person replace CPAP supplies?

The SoClean Automated Sanitizing Machine is designed to keep your CPAP equipment free from contaminants. The SoClean is not designed to extend the life of your CPAP equipment or accessories.

NOTE: SoClean recommends that CPAP patients adhere closely to the recommended replacement schedule of their CPAP equipment as set forth by their doctor, insurance company, and DME. Deviating from the recommended replacement schedule of a patients CPAP equipment can and will cause problems with a patient benefitting from effective, compliant CPAP therapy.

Why does SoClean recommend this? Please note a quote from SoundOxygen… “Some people will go through cushions or nose pillows faster regardless of how often or thoroughly they clean them due to the fact that their face produces more oils than others. On the other hand, if someone washes their cushion daily it may “last” for several months. Just because it lasts, doesn’t mean it shouldn’t be replaced though. Running shoes are a good analogy for CPAP supplies. One runner runs outdoors, on a trail that is dirty. The other runs on a treadmill. The first runner’s shoes will get dirty in one day, he may wash them and they will become clean but they are still essentially new in their ability provide support and cushioning. However, treadmill runner can run for several years before his shoes begin to look dirty. Yet, their ability to provide support and cushioning is gone even though the shoe looks clean. As time passes, the trail runner can easily know he needs new shoes just by looking. Yet the treadmill runner just needs to try on a pair to fully realize that his shoes are worn out even though they look new. Your CPAP mask can be the same way. Just because it looks clean and keeps a seal doesn’t mean that it doesn’t need to be replaced.”

Please note another quote. This time from CPAP Supply USA… “Many CPAP and BiPAP users don’t realize that most of the supplies associated with sleep therapy are designed to be disposable. Masks, tubing, filters, and head gear are not designed to last extreme amounts of time, and using them past their recommended life span can actually jeopardize your CPAP therapy. Delicate silicone mask cushions can develop leaks, clogged filters can allow dust and pollen to be delivered into your airway, and over-stretched headgear can require extreme tightening, causing pressure point pain.” For guidelines on when to order your CPAP equipment, please see the table below for Medicare’s schedule or call your insurance company to see when you would be eligible for new supplies.

(Many insurance companies follow Medicare’s resupply schedule)
