SnoreRx Plus vs PureSleep: Is the Upgrade Worth $40?

SnoreRx Plus costs $40 more than PureSleep ($99.99 vs $59.95). For that you get 1 mm jaw adjustment you can change any night, a hinge that lets your mouth open, and trays that come apart for cleaning. PureSleep locks you into one of three preset positions when you assemble it, but it gives you a longer 60-day money-back guarantee.

How we tested: We bought and tested both SnoreRx Plus and PureSleep ourselves; our hands-on notes and video reviews are below.

If you already know you snore most nights and want a device to keep, SnoreRx Plus is worth the upgrade. If you just want a cheap test of whether jaw advancement helps you at all, PureSleep is the lower-risk start. There is also a middle option: the original SnoreRx has the same 1 mm adjustment as the Plus, without the hinge, for about the price of PureSleep. We compare those two in PureSleep vs SnoreRx.

Quick Verdict

• Get SnoreRx Plus if you want to fine-tune your jaw position, you have felt trapped in a rigid mouthguard before, or you care about easy cleaning.
• Get PureSleep if budget matters most, you want 60 days to decide, or your bite is clearly an overbite or underbite and one of its three presets suits it.
• Get the original SnoreRx ($59.99) if you want adjustment at PureSleep’s price and don’t mind a hinge-free, closed-mouth design.
• Our hands-on tests: both reduced our tester’s snoring; SnoreRx Plus by more than 70% at its default setting.

What the $40 Upgrade Actually Buys

1. Adjustment you can change any night

PureSleep’s jaw position is chosen before you heat it: you snap the two trays together in the slot that matches your bite, then mold it. The three slots are roughly 4 mm apart, and once it is molded, the setting is effectively fixed.

SnoreRx Plus starts at 1 mm and moves forward one numbered step at a time. You unhook the upper tray, squeeze the “SQUEEZE” marks on the middle tray, slide the lower tray to the next number and hook the upper tray back on. The instruction booklet suggests three to five nights per step and says most people settle between 3 and 5 mm. If your jaw aches, you step back. That precision is the main reason we score it 9.3 for effectiveness against PureSleep’s 7.9. Our guide on how to adjust a snoring mouthpiece explains why small steps matter.

2. A hinge

PureSleep, like most two-tray devices, holds your mouth closed in one position. On SnoreRx Plus, the upper tray hooks onto the back of the middle tray, creating a hinge that lets your mouth open slightly. People who give up on rigid mouthpieces often describe a trapped, clenched feeling; being able to swallow and yawn more naturally is the Plus’s main comfort upgrade.

3. Easier cleaning

SnoreRx Plus comes apart into three pieces, so you can brush every surface, including the joint where buildup collects on one-piece devices. PureSleep’s two trays are cleaned as they are. See how to clean a snoring mouthpiece.

What PureSleep Does Better

• Price. $59.95 is $40 less, and it is an FDA-cleared device with a long track record: a prescription version was cleared in 2012 and the current over-the-counter version in 2019.
• A longer, easier trial. 60 days with a prepaid return label for U.S. orders, against 30 nights for SnoreRx Plus, which refunds the product price but not shipping.
• Bite-specific presets. The overbite and underbite settings give people whose bite isn’t “average” a sensible starting point without any tinkering.
• A soft liner. The firmer outer shell is lined with softer EVA where it meets your teeth, and the liner can be re-molded if the first impression goes wrong.

Comfort and Common Complaints

Both are full two-arch devices, and neither is small. Expect the first-week effects common to all jaw devices: morning jaw or tooth soreness, extra saliva, and a bite that feels slightly off for a while after you take it out. Specific to each:

• PureSleep: its front airway opening measured only about 3 mm in our test, which can feel restrictive if you breathe through your mouth or have a stuffy nose. A jaw that feels too far forward has only one fix: reassemble in a less-advanced slot and re-mold.
• SnoreRx Plus: the most common complaint is bulk, and buyers with a pronounced overbite report more trouble adapting. If the upper tray pops off, it usually isn’t hooked fully onto the middle tray after an adjustment.

Loose fit is a shared complaint, and in both cases a shallow impression is the usual cause. Follow the timings exactly and see our fitting guide. Pain that lasts beyond two weeks is a reason to stop and see a dentist (jaw pain from a snoring mouthpiece).

A Simple Way to Decide

Think of these as three steps up the same ladder:

1. PureSleep ($59.95): a fixed preset position and the longest trial. Good for finding out whether a MAD helps you at all.
2. SnoreRx ($59.99): adds 1 mm adjustment for about the same money, with a 30-night trial and no hinge.
3. SnoreRx Plus ($99.99): keeps the 1 mm adjustment and adds the hinge and take-apart trays.

If you are confident you will keep using a mouthpiece and want the most comfortable version of the adjustable design, go straight to the Plus. If you are unsure and want maximum return time, start with PureSleep. Full details on the original model are in SnoreRx vs SnoreRx Plus.

Our Hands-On Tests

We bought and tested both of these mouthpieces ourselves and filmed each test for our YouTube channel.

SnoreRx Plus

We bought SnoreRx Plus and tested it ourselves. It arrived with the fitting handle already in place, plus a case and instructions. We fitted it with a cup of water boiled in the microwave: 60 seconds in the water, a firm 30-second bite and 5 minutes in cool water, which left a clear impression of the teeth. Tested at the factory default setting, with no extra advancement, our recordings consistently showed snoring reduced by more than 70%. If you do advance it, the instructions say to go 1 mm at a time, every few nights.

Full details, photos and screenshots are in our SnoreRx Plus review.

PureSleep

We bought PureSleep and tested it ourselves. The box held the device in its case and an instruction manual. It comes as two pieces that you join in one of three positions before fitting: the front pair of holes for a typical bite, the center holes for a mild underbite and the back holes for a severe underbite (for an overbite, the manual says to use the center holes and flip the device over). We fitted it with 2 minutes in water at a low boil, a 15-second wait and a firm 30-second bite with the lower jaw held forward, after which the soft plastic fused and locked in the setting. The airway opening is only about 3 mm, which makes it a poorer choice for mouth breathers. Over three nights of wearing it, the recordings showed reduced snoring, and an overnight oxygen recording showed normal breathing.

Full details, photos and screenshots are in our PureSleep review.

What our testing adds to this comparison: Both worked in our tests. What the extra money bought us was flexibility: SnoreRx Plus can still be adjusted after fitting, while PureSleep’s setting was locked in once the plastic fused during fitting.

One tester’s nights are a real-world example, not a clinical trial. Snoring varies from person to person and night to night, and a snoring app or fingertip oxygen recording is not a sleep test.

Who Should Skip Both

Both devices need healthy natural teeth and move the jaw. Don’t use either, or ask your dentist first, if you:

• Are under 18.
• Wear braces or full dentures, or have loose teeth, abscesses or gum disease (for crowns, implants or partials, get your dentist’s approval).
• Have a history of TMJ disorder. See snoring mouthpieces and TMJ.
• Have central sleep apnea or another breathing disorder.
• Have symptoms that could mean obstructive sleep apnea: pauses in breathing, choking or gasping at night, morning headaches or heavy daytime sleepiness. Snoring can be a sign of apnea, so get a sleep test before treating it yourself. Both devices are cleared for snoring only.

Denture wearers usually do better with a tongue-stabilizing device; see SnoreRx Plus vs Good Morning Snore Solution.

Frequently Asked Questions

Is SnoreRx Plus worth the extra money over PureSleep?

If you will wear it nightly, usually yes. The extra $40 buys 1 mm adjustment you can change any night, a hinge, and trays that come apart. If you only want to test whether a mouthpiece helps, PureSleep’s lower price and 60-day trial make more sense.

Can PureSleep be adjusted after fitting?

Not in small steps. It has three preset positions about 4 mm apart, chosen when you assemble it. Changing position means reassembling it in another slot and re-molding.

How is SnoreRx Plus different from the original SnoreRx?

Both use boil-and-bite fitting and 1 mm adjustment. The Plus adds a hinge for vertical jaw movement and comes apart into three trays. It costs $99.99 against $59.99. See PureSleep vs SnoreRx for how the original compares with PureSleep.

Which has the better guarantee?

PureSleep: 60 days with a prepaid return label for U.S. orders. SnoreRx Plus offers 30 nights for new customers buying at snorerx.com, refunding the product price but not shipping.

Are SnoreRx Plus and PureSleep FDA cleared?

PureSleep’s over-the-counter version was cleared in 2019 (K190058) as an aid to reduce snoring in adults. SnoreRx Plus is sold as FDA-cleared for snoring as part of the SnoreRx line. Neither is cleared to treat sleep apnea.
