SnoreRx vs PureSleep: Which Anti-Snoring Mouthpiece Is Better?

If you’re down to SnoreRx or PureSleep, the thing you’re trying to avoid is ordering the wrong one. The wrong pick can leave you dealing with an uncomfortable fit, continued snoring or a product that doesn’t suit your needs.

At checkout the two look interchangeable, with PureSleep advertised at $59.95 and our original SnoreRx at $59.99 before any shipping or tax.

The difference shows up after the first night. PureSleep’s position is set for your bite at assembly and locked once you mold it, while SnoreRx keeps moving 1 mm at a time until the snoring eases at a setting your jaw can live with.

Because SnoreRx is ours, every PureSleep detail we cite comes from PureSleep’s own instruction guide and policies, and we flag the places where it beats us.

Key Takeaways

• PureSleep’s three positions match your bite, and SnoreRx’s six settings move your jaw. PureSleep assigns its assembly positions to a typical bite, an underbite or an overbite and locks them in once molded, while SnoreRx moves through six 1 mm settings whenever you need it.

• The standard models cost almost the same. At their advertised prices, PureSleep is $59.95 and our original SnoreRx is $59.99 before shipping and tax, so you’re choosing between a fixed position and one you can keep adjusting.

• PureSleep wins on returns. Its 60-day window includes a prepaid return label on US orders placed with PureSleep, and our 30-night guarantee starts at delivery on orders at snorerx.com.

• Comfort depends on your mouth more than the brand. PureSleep’s thin outer shell is designed to cut bulk, and our one-size SnoreRx takes some getting used to. SnoreRx leaves the front open for mouth breathing, and SnoreRx Plus adds a hinge.

• Pick the SnoreRx that suits your jaw. Either model ships on its 1 mm setting, and snorerx.com orders include 30 nights to try it, so browse both models and choose the one you’ll keep adjusting.

SnoreRx vs PureSleep, Feature by Feature

For a SnoreRx vs PureSleep comparison that holds up, it helps to split our two models, because they fit and adjust the same way but behave differently once you’re asleep. PureSleep sells one mouthpiece, so it sits in a single column against both.

Of all these differences, jaw position is the one you’ll feel most by your second or third week of wear.

What Both Mouthpieces Do While You Sleep

SnoreRx and PureSleep are both mandibular advancement devices. They hold your lower jaw slightly forward while you sleep, which gives your airway more space, so the soft tissue in your throat flutters less.

On PureSleep, you set that forward position once, during assembly and molding. SnoreRx molds to your teeth once, and the jaw position stays adjustable for as long as you wear it.

If you’re new to the category, our guide to adjustable mouthpieces walks through the basics of how they’re set up.

How Adjustable Are SnoreRx and PureSleep After Fitting?

SnoreRx can be adjusted on any night you choose, and PureSleep can’t be adjusted at all once it’s molded. PureSleep says its device is adjustable during the initial fitting only, and that after molding it keeps its shape for good.

In a PureSleep vs SnoreRx comparison, it’s easy to read PureSleep’s three positions as advancement levels, which makes the two mouthpieces sound closer than they are. PureSleep’s instruction guide treats them as bite settings you choose once.

How PureSleep’s Bite Settings Work

PureSleep arrives as an upper and a lower piece that you join by pressing plastic pins into one of three pairs of holes. The guide matches each pair to a bite type, and the overbite setting uses the center holes with the assembled piece turned upside down.

Each position changes where the lower piece sits, but PureSleep assigns them by bite type, so you pick the one that matches your teeth and stay there. Its guide doesn’t list how many millimeters of advancement each position gives.

If you can’t tell whether you have a typical bite or an overbite, PureSleep suggests trying both. Once the plastic is molded, the position you chose is the one you sleep in.

How SnoreRx’s 1 mm Adjustments Work

Both SnoreRx models ship on the 1 mm setting and can travel forward one millimeter at a time, to a maximum of 6 mm. To change it, you press in on both sides of the tray, move the lower half one number along the built-in gauge and release it to lock the new setting.

SnoreRx Plus adds one step, since the top tray unhooks before you adjust and clips back on when you’re done. No tools are involved, so moving forward or back a setting takes a few seconds at bedtime.

If snoring persists, follow the SnoreRx instruction booklet by wearing each advancement setting for at least 3 to 5 nights before increasing it again. Most of our wearers settle somewhere between 3 and 5 mm.

Adjusting the SnoreRx takes a single squeeze, and the clip below shows what that looks like in your hand.

Why Adjustability Matters After the First Night

The right amount of advancement differs from person to person, and you rarely know yours on the first night. Too little leaves the snoring in place, and too much can leave your jaw aching by morning.

With SnoreRx, either miss has a one-step fix in the direction you need.

With PureSleep, the assembly position stays fixed after molding. You can try improving the tooth impression through refitting, but you can’t fine-tune the jaw position afterward.

Fitting SnoreRx and PureSleep at Home

You shape both mouthpieces in hot water at home, and the routines only start to differ once you look at the timings. PureSleep also adds an assembly step before anything goes in the water, since the hole position has to match your bite first.

Our Thermal Matrix Design turns soft in hot water so it can take a personalized impression of your teeth, and our fitting instructions cover every step for both models.

If you’d rather watch the routine, here’s what fitting SnoreRx looks like from the hot water to the final set.

Is SnoreRx or PureSleep More Comfortable to Wear?

Neither mouthpiece wins on comfort for every mouth. Each brand made different trade-offs, so it comes down to which ones your mouth puts up with better.

Bulk, Jaw Movement and Mouth Breathing

PureSleep pairs a soft moldable lining with a thin outer shell meant to reduce bulk. SnoreRx comes in a single size, and people with smaller mouths can find it bulky until they get used to it.

Mouth breathing tips the other way. SnoreRx leaves the front open to make room for airflow when you breathe through your mouth, while PureSleep relies on small breathing holes that Sleep Foundation testers found didn’t allow much airflow.

Sleep Doctor named SnoreRx its ”Most Comfortable” pick in its 2026 anti-snoring mouthpiece guide, although comfort remains subjective and depends on individual fit. SnoreRx Plus also has a hinge that lets the lower jaw drop and rise during sleep, something the one-piece original doesn’t have.

Jaw Soreness and the First Week

Expect some soreness with either one. PureSleep’s guide warns of moderate jaw, tooth and gum soreness for up to five days, and our instructions mention sore teeth, extra saliva and a dry mouth in the first few nights.

Before your first night, get used to the feel by wearing SnoreRx around the house for one to three hours a day over two or three days, then sleep at the 1 mm setting. PureSleep’s guide adds a gentle jaw stretch each morning to help your bite settle back into place.

SnoreRx vs SnoreRx Plus for Comfort

In the SnoreRx vs SnoreRx Plus choice, the fit and the 1 mm adjustment are identical. What the Plus adds is a hinge that gives your jaw some up-and-down travel, along with trays you can separate to clean.

We built that hinge for people whose jaw moves while they sleep, though it doesn’t guarantee that SnoreRx Plus will feel better in your mouth than the original.

If you grind or clench your teeth, consult your dentist before choosing either model. We suggest the original SnoreRx over SnoreRx Plus if you grind, but neither model is intended to treat teeth grinding, known as bruxism, and heavy grinding may shorten its lifespan.

What Happens if Your Mouthpiece Doesn’t Work?

When the first setup doesn’t reduce your snoring or doesn’t sit right, SnoreRx gives you more to try before you give up on it. PureSleep’s main safety net is its longer return window.

If you’ve worked up as far as you can comfortably go and the snoring hasn’t changed, call our team at 1-800-546-1984 before your 30 nights end so we can look at your fit with you.

PureSleep will exchange a device you accidentally damage during fitting, which takes some pressure off a first attempt. That’s a thoughtful policy for anyone who’s nervous about molding a mouthpiece at home.

When to Stop Using a Mouthpiece and Seek Advice

Both makers list tooth movement and bite changes among the possible side effects, and neither device should be pushed further forward through pain. Stop wearing either mouthpiece and speak with your dentist if any of these happen.

• Your bite feels different once the mouthpiece is out, and it doesn’t settle as the morning goes on.

• One or two teeth feel much more sensitive than the rest.

• Your jaw clicks, pops or hurts sharply when you open and close your mouth.

• Soreness builds over several nights when it should be fading.

• Someone notices you stop breathing or gasp during sleep, which calls for a doctor before any mouthpiece.

SnoreRx vs PureSleep Price and Yearly Cost

On SnoreRx vs PureSleep price, the standard models are effectively tied, with PureSleep advertised at $59.95 including free US shipping and our original SnoreRx at $59.99. SnoreRx Plus costs $99.99, and our prices are before any shipping or tax.

Comparisons that call PureSleep the cheaper option are working from a gap that no longer exists between the standard models. Neither one lasts forever, so it’s worth pricing a second mouthpiece too.

These figures use each maker’s listed price before tax and leave shipping out. On the same six-month replacement schedule, a year of SnoreRx costs $99.99 with our two-pack, while two PureSleep mouthpieces come to $119.90.

PureSleep’s replacement subscription runs from every 3 months for people with severe grinding to every 12 months for moderate snorers who don’t grind.

Cleaning differs a little. PureSleep suggests a weekly deep clean with a toothbrush or cleaning tablets, while SnoreRx gets brushed after every use and never goes near denture tablets.

A dry, ventilated case between nights helps either device last, and our hygiene tips walk through a full routine.

Which Has the Better Return Policy?

PureSleep has the stronger return policy, and it’s a fair reason to lean its way if you’re unsure about mouthpieces in general. You get 60 days from purchase to return it for any reason, and US orders placed through PureSleep include a prepaid return label.

PureSleep’s returns apply to orders bought directly from PureSleep, and PureSleep notes that Buy with Prime orders aren’t covered. Check where you’re buying before you count on that 60-day window.

If you’re a new customer ordering at snorerx.com, either model comes with our 30-night guarantee, and the clock starts when your order is delivered. If it doesn’t suit you, send it back within those 30 nights and we’ll refund the product price, though shipping and handling aren’t refunded.

Our 30-night guarantee gives you time to evaluate SnoreRx, although testing multiple settings may take several weeks. Start at 1 mm, follow the adjustment instructions and keep track of your return deadline, which begins on the delivery date.

What SnoreRx and PureSleep Customers Actually Report

SnoreRx vs PureSleep reviews include reports of quieter nights for both brands, along with complaints about fit and comfort.

Positive Experiences

On snorerx.com, more than 2,300 verified customer reviews give SnoreRx an average of 4.9 out of 5. PureSleep’s happiest reviewers sound much the same, and Serdar wrote on Trustpilot in May 2025 that it stopped the snoring on the very first night and has worked ever since.

Common Comfort and Fitting Complaints

Bulk is one recurring complaint about SnoreRx, particularly among customers who find the mouthpiece too large for their mouths. Anna H gave SnoreRx Plus three stars on Trustpilot in September 2026 for that reason, even though it stopped her snoring.

Fit comes up in some of PureSleep’s lower-rated reviews too. In a 2021 review, Melissa Maskell wrote that it never fit the structure of her teeth.

Tooth movement comes up too, with one 2020 PureSleep reviewer, V Matt, saying it worked for snoring but shifted their teeth. That’s one person’s account, though both instruction guides list tooth movement as a possible side effect.

The most useful review we found came from someone who wore both. A Reddit user tried each mouthpiece for about two weeks and found both reduced their snoring, but preferred PureSleep because SnoreRx felt too bulky and left their jaw uncomfortable.

We’d rather you hear that before you buy than after. Bulk is the trade-off that comes with our one-size tray, and the 1 mm settings are what you get in return.

What Reviews Can’t Tell You

Trustpilot is a rough guide for both brands. SnoreRx scores 1.3 out of 5 there from fewer than 100 reviews, many of them about delivery, refunds or customer service rather than the mouthpiece itself.

PureSleep’s Trustpilot profile shows 2.2 from 633 reviews, and a number of them were clearly meant for companies with similar names, including a vacuum seller.

No review can tell you how your own bite will take to either device. That’s what a trial window is for, so it’s worth weighing the return terms as carefully as the star ratings.

When to Hold Off on Either Mouthpiece

Both makers rule out the same broad groups, but the details differ. If any of these apply to you, talk to your dentist before you buy either mouthpiece.

Where the two makers disagree with each other, or PureSleep’s guide and FAQ disagree, go with the stricter advice and ask your dentist.

Can SnoreRx or PureSleep Treat Sleep Apnea?

No, our clearance from the FDA covers the reduction of snoring only, and SnoreRx isn’t cleared by the FDA to diagnose obstructive sleep apnea or to treat it. PureSleep’s guide says its own device isn’t indicated for obstructive sleep apnea either.

Snoring on its own isn’t the same thing as sleep apnea, though loud nightly snoring can be one sign of it. Anyone who suspects apnea should talk to a healthcare professional first, and our snoring treatment guide lists the signs worth raising with them.

The American Academy of Sleep Medicine (AASM) recommends that sleep physicians prescribe oral appliances, over no treatment, for adults who ask for help with primary snoring. For obstructive sleep apnea, it suggests a custom appliance that a qualified dentist fits and adjusts, which is a different kind of device from SnoreRx or PureSleep.

Who Should Choose SnoreRx and Who Should Choose PureSleep?

Choose SnoreRx if you want room to adjust after the first night. PureSleep earns the pick in a handful of cases, mostly around returns and a thinner shell.

If none of PureSleep’s strengths match what you need, SnoreRx costs the same to start and hands you six chances to get the position right instead of one.

Both SnoreRx models give you the same adjustment after fitting, from 1 mm to 6 mm. The original SnoreRx is the one-piece design at $59.99, while SnoreRx Plus adds vertical jaw movement and an upper tray that detaches for cleaning for $99.99.

Find the Setting That Lets You Both Sleep

If your snoring already has your partner reaching for earplugs, you want a mouthpiece that allows more than one shot at the right position. SnoreRx always has another setting to try, so you can work toward quieter nights without forcing your jaw further than it wants to go.

Each model is made in the USA and FDA-cleared to reduce snoring, and you get a full 30 nights to judge yours at home. Shop SnoreRx to pick your model and try your first setting this week.

FAQs About SnoreRx vs PureSleep

Is SnoreRx better than PureSleep?

SnoreRx is the better choice if ongoing jaw adjustment is a priority, because it keeps adjusting after fitting while PureSleep stays wherever you molded it. The standard models cost almost exactly the same, at advertised prices of $59.99 and $59.95.

PureSleep is the better pick if you want 60 days to return it or a thinner shell.

Can you adjust PureSleep after fitting?

No. Once PureSleep is molded, its position is permanent, so the assembly holes you pick at the start set your advancement for the life of the device.

You can redo the fitting if the first impression feels wrong, but refitting only reshapes how the trays grip your teeth and leaves the assembly position where it was.

Is PureSleep cheaper than SnoreRx?

Yes, but only by four cents at the standard models’ advertised prices, $59.95 for PureSleep against $59.99 for our original SnoreRx. PureSleep also includes free US shipping, and SnoreRx Plus costs $99.99.

Swap either one out twice a year and you’d pay $99.99 for our SnoreRx two-pack against $119.90 for a pair of PureSleep mouthpieces.

Which one suits mouth breathers better?

SnoreRx may be preferable for some mouth breathers because its open-front design accommodates airflow. PureSleep uses smaller breathing holes, which Sleep Foundation testers found restrictive.

Individual fit still matters, and neither device guarantees unobstructed mouth breathing. If a blocked nose is why you breathe through your mouth, PureSleep’s own guide suggests treating the congestion first.

Can you use SnoreRx or PureSleep with an overbite or underbite?

PureSleep addresses bite type more directly, with separate assembly positions for a typical bite, a mild underbite, a severe underbite and an overbite. SnoreRx takes an impression of your own teeth in one size, and one four-star reviewer on snorerx.com found it hard to get used to with an overbite.

If your bite is unusual, ask your dentist which design suits it before you order.

Does it matter where you buy SnoreRx or PureSleep?

Yes, because both return policies depend on it. Our 30-night guarantee applies to orders placed at snorerx.com, and PureSleep’s prepaid return label covers US orders placed through PureSleep, with Buy with Prime orders excluded.

You can also pick up SnoreRx at CVS and Walgreens.

Should I get SnoreRx or SnoreRx Plus?

Get the original SnoreRx at $59.99 if you want the lower price. SnoreRx Plus, at $99.99, suits you if you’d like your jaw free to move vertically and trays that come apart for brushing.

The two share one fitting routine and the same six settings. If you grind or clench, see your dentist before ordering, and know that we favor the original for grinders though neither model treats it.

If you’re still choosing between our original SnoreRx and SnoreRx Plus, compare both models and order whichever fits your budget and the way you sleep.
