SnoreRx is the better mouthpiece for most snorers, and the two now cost almost exactly the same. Both are boil-and-bite mandibular advancement devices (MADs) that hold the lower jaw slightly forward, but SnoreRx can be re-adjusted in 1 mm steps after fitting, while PureSleep keeps whatever jaw position you set when you mould it.
On our scorecards SnoreRx rates 8.8 out of 10 overall and PureSleep 7.9. Price no longer separates them: PureSleep is $59.95 and SnoreRx is $59.99. PureSleep’s one clear advantage is its longer money-back guarantee, 60 days against 30 nights. This page explains what the adjustment mechanism adds and when the simpler device is the sensible choice.
Quick Verdict: PureSleep or SnoreRx?
- Choose SnoreRx if you plan to wear a mouthpiece every night and want to fine-tune how far your jaw sits forward. It scores higher for effectiveness, comfort and ease of use.
- Choose PureSleep if you want a simple device with a longer 60-day money-back guarantee and mainly want to find out whether a jaw-advancing device helps your snoring at all.
- Choose neither if you have loose teeth, dentures, untreated gum disease or jaw joint (TMJ) problems. See the section on who should skip both, further down.

How Each Mouthpiece Works
Snoring is the sound of soft tissue in the throat vibrating as air squeezes past it. When you fall asleep the jaw and tongue relax and drop back, which narrows the airway. A MAD grips the upper and lower teeth and holds the lower jaw a few millimetres forward so the airway stays more open. Our guide to how snoring mouthpieces work covers this in more detail.
PureSleep and SnoreRx both do exactly this, and both are FDA cleared for snoring. Neither is a treatment for sleep apnea. The real difference between them is how the forward jaw position is chosen and whether you can change it later.
Fit and Adjustment
Fitting PureSleep
PureSleep is a two-piece device. Before you mould it, you join the upper and lower pieces in the setting that matches your bite, and that choice decides how far your jaw is held forward. You then soften the device in hot water and bite into it to take an impression of your teeth.
Once that is done, the jaw position is fixed. Our PureSleep review notes that the device can be re-boiled up to three times to improve the impression, but there is no dial or screw for nudging the jaw forward or back a little on a later night. If the position turns out to be too mild to stop your snoring, or too strong for your jaw, your options are limited.
Fitting SnoreRx
SnoreRx is also boil-and-bite, so you get the same kind of custom impression of your teeth. The difference is the calibrated mechanism between the upper and lower trays. It moves the lower tray in 1 mm increments, and you can change the setting whenever you like without re-moulding.
That lets you start with a small amount of advancement, wear it for a few nights, then move forward one step at a time until the snoring stops. If your jaw feels sore, you move back a step. Our guide on how to adjust a snoring mouthpiece walks through that process.
Why adjustment after fitting matters
The right amount of jaw advancement differs from person to person. Too little and the airway still narrows. Too much and the jaw joint and teeth take more strain than they need to. With a fixed device you make one guess at fitting. With a calibrated device you can correct the guess. This is the main reason SnoreRx scores 9.0 for effectiveness against 7.9 for PureSleep.
Winner for fit and adjustment: SnoreRx.
Comfort
We score SnoreRx 8.5 for comfort and PureSleep 7.6. Neither is a small device. A somewhat bulky feel in the mouth is one of the most common complaints about both, and both tend to cause some jaw or tooth soreness and extra saliva in the first week while the mouth gets used to them.
A few points separate the two:
- Dealing with soreness. With SnoreRx you can ease the advancement back by 1 mm if your jaw aches. With PureSleep you can only wait it out or re-mould. Our review suggests allowing a break-in period of 3 to 5 days for PureSleep.
- Materials. PureSleep uses two plastics, with a softer one on the inside where it meets the teeth. It is latex-free and has no added BPA. SnoreRx is made from a medical-grade copolymer.
- Mouth breathing. Our PureSleep review points out that its air holes are fairly small, which could feel restrictive if you mainly breathe through your mouth at night.
- The fitting itself. A rushed boil-and-bite impression is behind many comfort complaints with PureSleep, so take your time. The same advice applies to SnoreRx. Our fitting guide covers the technique.
If soreness lasts beyond the first couple of weeks with either device, stop using it and speak to a dentist. Our page on jaw pain from a snoring mouthpiece explains what is normal and what is not.
Winner for comfort: SnoreRx.
Value: Price and Guarantee Compared
PureSleep costs $59.95 and SnoreRx costs $59.99, a gap of four cents. On value, the two are almost level in our scoring: 8.6 for PureSleep and 8.5 for SnoreRx. Both are among the lowest-priced mouthpieces we recommend. For the same money, SnoreRx gives you adjustment after fitting.
Both come with a money-back guarantee, and PureSleep’s is longer: 60 days against 30 nights for SnoreRx. Read the return terms on the merchant's site before you order, because conditions can change.
A practical way to think about it:
- If you are unsure whether any jaw-advancing mouthpiece will suit you, PureSleep’s 60-day guarantee gives you longer to find out.
- If you already know you snore most nights and expect to wear a device long term, the adjustability of SnoreRx is likely to matter more than the longer guarantee.
All boil-and-bite mouthpieces wear out and need replacing from time to time, sooner if you grind your teeth. Our guide on how long snoring mouthpieces last explains the signs to look for.
Winner for value: PureSleep, narrowly.
Who Should Buy PureSleep?
- First-time buyers who want to try a MAD with a 60-day money-back guarantee.
- People with simple snoring who are happy with a basic device and do not expect to fine-tune it.
- Anyone buying a spare or a first test device before committing to a more adjustable one.

Who Should Buy SnoreRx?
- Nightly snorers who want precise control over jaw position.
- People who tried a fixed mouthpiece and found it either did not go far enough or made the jaw sore.
- Buyers who would rather start with a calibrated device than buy a fixed one and upgrade later.

Who Should Skip Both
PureSleep and SnoreRx both grip the teeth to hold the jaw forward. That makes them a poor fit for some people:
- People with dentures, loose teeth, untreated gum disease or recent major dental work.
- People with TMJ pain or a jaw that clicks or locks.
- Anyone under 18.
- Anyone who has, or suspects, sleep apnea. Loud snoring with pauses in breathing, gasping or heavy daytime sleepiness should be checked by a doctor first. An over-the-counter mouthpiece is not a treatment for sleep apnea.
If the issue is your teeth or jaw, a tongue device such as Good Morning Snore Solution works without gripping the teeth. See who should not use a snoring mouthpiece for the full list, and ask your dentist if you are unsure.

The Bottom Line
SnoreRx is the stronger mouthpiece: it scores higher for effectiveness, comfort and ease of use, and its 1 mm adjustment lets you correct the fit instead of living with your first attempt. PureSleep is the right buy when the longer 60-day guarantee is the deciding factor or you only want a simple, low-cost trial of a jaw-advancing device.
Frequently Asked Questions
Is SnoreRx better than PureSleep?
For most people, yes. SnoreRx scores 8.8 overall against 7.9 for PureSleep in our ratings, mainly because its jaw position can be adjusted in 1 mm steps after fitting. PureSleep is the better choice only if its longer 60-day money-back guarantee matters most to you.
Can you adjust PureSleep after fitting it?
Not in the way you can with SnoreRx. You choose the jaw setting before moulding PureSleep, and it stays there. Our review notes the device can be re-boiled up to three times to improve the impression, but it has no mechanism for small changes afterwards.
Is PureSleep cheaper than SnoreRx?
Only by four cents. Based on the prices we list, PureSleep is $59.95 and SnoreRx is $59.99, so price is no longer a reason to choose one over the other. Prices and offers change, so check the merchant before you buy.
Do PureSleep and SnoreRx both need boiling?
Yes. Both are boil-and-bite devices: you soften the mouthpiece in hot water, then bite into it to take an impression of your teeth. Follow the instructions in the box exactly, because the timings differ between products.
Can I use PureSleep or SnoreRx for sleep apnea?
No over-the-counter mouthpiece should be used as a treatment for sleep apnea. Both devices are sold for snoring. If you have been diagnosed with sleep apnea, or have symptoms such as pauses in breathing or gasping at night, see a doctor before using either one.
Which one is more comfortable?
We score SnoreRx 8.5 for comfort and PureSleep 7.6. Both feel bulky at first and can cause short-term jaw soreness, but SnoreRx lets you reduce the advancement if your jaw aches, which PureSleep does not.
