VitalSleep VS PureSleep

When you – or your partner – snores, it doesn’t just disrupt sleep. It can strain your relationship and lead to serious health issues, from fatigue and irritability to long-term risks.

With so many snoring solutions available – from pillows and nasal devices to surgery and CPAP machines – it’s hard to know what really works.

Before spending your money, it's important to compare your options carefully. Here’s how VitalSleep compares against PureSleep, so you can choose the solution that’s right for you. For a more in-depth guide, here is our full PureSleep mouthguard review.

When choosing the right Mandibular Advancement Device (MAD), several key factors should guide your decision: comfort, adjustability, fit, material quality, and overall effectiveness. If you're still weighing your options, start with our guide to what causes snoring and how to stop it.

Manufacturing

Title

Unlike PureSleep, which uses a fixed jaw position, VitalSleep offers full adjustability with its patented Accu-Adjust System. This system lets users advance the lower tray in 1 mm increments, up to 7 mm, by simply turning two adjustment screws. See how the Accu-Adjust System works.

This precise control allows users to gradually find the ideal jaw position for maximum airway opening and snoring relief, all while minimizing the soreness that often comes with using a fixed-position mouthpiece like PureSleep.

VitalSleep is among the most adjustable mandibular advancement devices (MADs) available, giving you a more customized, comfortable, and effective solution.

Customization

Title

Using the boil-and-bite method, users are able to mold the devices to fit their teeth which helps deliver a custom fit.
However, PureSleep reviews indicate their boil-and-bite material cannot be redone after one fitting, despite their claim this can be done up to three times if the customer gets it wrong the first time. Some also assert that the material is very heat-sensitive and report that their “own body heat during sleep gradually deformed the fit.”
Another issue reported with PureSleep is the boil-and-bite method is said to be “tricky” and reported to be “confusing.”

VitalSleep’s boil-and-bite method is simple and allows users to customize the fit comfortably without much fuss. Further, VitalSleep offers two sizes: male and female (large and small, respectively), allowing an even more customized fit.

Adjustability

Title

When using an anti-snoring mouthpiece, some users may have discomfort in the beginning. That’s where devices that offer adjustments are helpful in making the adjustments more bearable.

Both of these products are adjustable but different in the way they adjust.

PureSleep has three settings that allow users to either loosen or tighten their device. However, they warn that once the device is molded, no further adjustments can be made.

A consumer complaint filed in the U.S. Food and Drug Administration’s MAUDE adverse-event database described serious injury to the temporomandibular joint (TMJ) after use of the PureSleep device, with the user reporting months of pain and, ultimately, surgery. MAUDE reports are submitted by consumers and are not verified by the FDA.

With VitalSleep’s patented Accu-Adjust System, users are able to slowly adjust the device 1 mm at a time with the turn of a couple of screws. Small, gradual increments help reduce discomfort and place less sudden stress on the temporomandibular joint than abrupt changes in jaw position.

Sizes

Title

Since people have different size mouths, having more than one size available is important. VitalSleep comes in two sizes: men’s and women’s, with the women's size approximately 10% smaller. PureSleep is available in one universal size.

Guarantees/Refunds

Title

When trying out a new product, the guarantee matters. Being able to return or exchange the device safeguards you against losing money and precious sleep.

PureSleep offers a 60-day money-back guarantee and includes a prepaid return shipping label with each order.

VitalSleep also offers a 60-night, 100% money-back guarantee, and goes further with a one-year free replacement guarantee, no questions asked.

Exchanges and Returns

Title

Both companies accept returns within their guarantee windows. Where VitalSleep pulls ahead is its one-year free replacement guarantee and two available sizes, which increase the chance you get the right fit the first time. If you order the wrong size, you can easily exchange it for the other size.

Shipping

Title

Both companies offer free shipping, but delivery speeds are vastly different.

PureSleep offers free shipping and online orders are received in one to two weeks with regular shipping and one week with express. Phone orders are said to arrive in three to four weeks or two weeks with express shipping.

They claim to provide international shipping on a “select list of countries” outside of the U.S.

VitalSleep provides free shipping anywhere in the world and ships on the same day the order is placed by 4 PM, PST.

Customer Ratings

Title

Customer reviews tell you how a product performs in the real world, not just on paper.

VitalSleep has more than 1,000 verified customer reviews collected on VitalSleep.com, with an average rating of 4.5 out of 5 stars. On Trustpilot, an independent third-party review platform, VitalSleep holds an “Excellent” 4.5-star rating across 200+ reviews, while PureSleep’s rating sits noticeably lower as of July 2026.

The Better Business Bureau gives both companies an A+ rating, though PureSleep’s BBB customer review score is lower than VitalSleep’s.

Durability

Title

PureSleep suggests their product be replaced every six to nine months, although some users may need to replace it more often if they grind their teeth.

VitalSleep suggests their product lasts 1 year or more with regular use, but longevity will vary depending on the amount of use. However, with a one-year replacement guarantee, individuals who grind their teeth are covered with a replacement device even if it wears out within that first year.

Cost

Title

PureSleep typically costs less upfront and comes with its money-back guarantee.

VitalSleep costs more, but the price includes a full year of free replacements, so one purchase covers your first year of use, even if you grind your teeth and wear the device out. Current pricing and bundle options are always on the VitalSleep product page.

While each product has its pros and cons, VitalSleep wins this round with a longer guarantee, free replacements, worldwide same-day shipping, and exceptional customer reviews. Want to see how VitalSleep stacks up against other mouthpieces? See our full comparison vs SnoreRx and ZQuiet.
