Sleep8 vs SoClean 2 (2021): Which Is the Better CPAP Cleaner?

If you use CPAP for your sleep apnea, it is imperative that you also regularly clean your CPAP equipment. Failing to do so may lead to more health issues as you may end up inhaling harmful bacteria, mold, and other pathogens. The problem is cleaning all the parts of the CPAP equipment can be tedious, so some just haphazardly clean the parts or worse, forget about it altogether. This is why investing in a CPAP cleaner like Sleep8 and SoClean is important, not just for your CPAP machine, but for your overall health. They make cleaning so convenient that you can do it every day, even while you’re away.

Sleep8 is a relative newcomer in the industry while SoClean has been in the game for a while. Keep reading our in-depth comparison of the two so you can better decide which CPAP cleaner is the better investment.

Design & Ease of Use

Sleep8 and its filter bag is more travel-friendly than the SoClean machine

The design of Sleep8 and SoClean cannot be more different. Sleep8 uses an 8-shaped cleaning device that connects to the filter bag. Whenever you need to clean the parts of your CPAP or BiPAP, you can just throw them inside the bag and seal, connect the Sleep8 device into the port, and turn the device on to start cleaning. No adapter needed. The filter bag can be folded, too, making it easier to pack so you can clean your CPAP machine while on the go. Weighing only .63 lbs, the Sleep8 device itself is remarkably lighter than the SoClean machine that weighs 7 lbs.

Meanwhile, SoClean is heftier, so it’s not ideal for traveling. It’s still easy to use and makes cleaning CPAP equipment convenient. Simply put the mask inside SoClean, adjust the machine to your preferred settings, and make sure that it’s sealed while it’s cleaning. Unlike Sleep8, however, SoClean requires a tube adapter in order to use it with your machine. There are adapters for all makes and models and SoClean even includes the popular adapters out of the box.

Sanitizing Performance & Cleaning Time

Both use ozone to sanitize your CPAP machine, but the SoClean 2 does the job faster than Sleep8

It only takes 60 minutes for Sleep8 to kill the germs in your CPAP gear

Using activated oxygen, or ozone, both Sleep8 and the SoClean 2 promise to kill 99.99% of the pathogens in your CPAP machine or other parts such as the mask and tube. This alleviates the need to use strong chemicals such as detergent to clean your mask and tube. While they are primarily marketed as CPAP cleaners, both devices can also sanitize BiPAP or APAP masks as long as they fit in Sleep8’s sanitizing bag and SoClean’s sanitizing chamber.

Both CPAP cleaners are securely sealed to prevent ozone leakage during the sanitization process. Sleep8’s sanitizing bag works like your regular zip-lock bag while its device is equipped with a safety feature that makes it beep if the device is not properly connected to the bag. The SoClean 2’s chamber is designed to avoid ozone leakage as well, but some users have still complained about leaking.

A major difference between Sleep8 and SoClean is their cleaning time. Both will automatically stop cleaning once they’re done, but SoClean’s cleaning time is shorter. It only takes 5 to 10 minutes for a microbe-free CPAP machine and gear while it takes Sleep8 60 minutes. The SoClean 2 can further be programmed to clean at a certain time so you can schedule the cleaning while you’re away. You might want to schedule the cleaning while you’re away as the SoClean 2 is significantly louder than the quiet Sleep8 device.

Warranty and Free Trial

Both offer a 30-day money-back guarantee and up to two years of warranty for certain partssleep8 vs soclean (3)

The SoClean 2 has an indicator that notifies you when it’s time to change its cartridge filter

CPAP cleaners like Sleep8 and SoClean are not cheap, so it’s important to factor in the additional expenses you will incur when you purchase one. Sleep8 recommends changing the filter bag every three months or so if you use it every day, longer if you only use it to clean every other day or so. Meanwhile, the SoClean 2’s filter cartridge typically lasts up to 6 months depending on how frequently you use the machine. Its display on the front will let you know once it’s time for a filter kit replacement. With that said, the Sleep8 filter bag is cheaper than the cartridge filter kit of the SoClean 2.

You can try either Sleep8 or the SoClean 2 for 30 days and get a refund if you are dissatisfied with the product. They will send you a pre-paid shipping label so you can return the CPAP cleaner at no cost to you. As for their warranty, both offer up to 2 years for manufacturer or workmanship defects for the machines. It is worth noting that you should check with your CPAP manufacturer as to whether using a CPAP cleaner like Sleep8 or SoClean will void their warranty.


Sleep8 is more versatile and easy to use than the SoClean 2

Both Sleep8 and the SoClean 2 do a great job of cleaning your CPAP machine, tube, and mask. This means choosing between the two comes down to the bells and whistles that you prefer. Sleep8 is designed so you can consistently clean your CPAP machine even when traveling, thus avoiding any health issues that may develop from unsanitized mask and tube. It’s also quieter and its filter bag ensures a secure seal without all the fuss that dealing with the SoClean 2 requires. Meanwhile, the SoClean 2 better fits you if you don’t travel often and don’t mind its bulky frame. Its programmable cleaning schedule and longer filter life are major pluses, too.


📌 Which is better, Sleep8 or SoClean?

Both Sleep8 and SoClean clean your CPAP machine through activated oxygen, so in regard to their cleaning prowess, you can’t go wrong with either. However, Sleep8 is more travel and user-friendly than the SoClean 2.

📌 Is SoClean worth the money?

CPAP cleaners like SoClean and Sleep8 are worth the money as they make it easier to develop the habit of cleaning your CPAP machine, mask, and tube. Failing to do so may cause bacterial growth, which may consequently lead to health issues.

📌 Should I wear my CPAP if I have a cold? 

Yes, wearing a CPAP can help soothe the symptoms of cold and flu. Just make sure to clean your CPAP regularly to avoid the growth of pathogens in your CPAP gear.

📌 Does SoClean clean the hose? 

Yes, the SoClean 2 also cleans the tube without having to detach it from the mask. Just make sure the hose is properly connected to the machine to avoid ozone leakage.
