HOW IT WORKS
STEP 1

Soften QuietGuard™ in hot water according to the included fitting instructions.

STEP 2

Allow it to cool as directed, then mold it carefully around your teeth to create a more personalized shape.

STEP 3

Wear QuietGuard™ during sleep. It is designed to support a slightly forward lower-jaw position and help reduce disruptive snoring.

STEP 4

Rinse it with cool or lukewarm water after use and allow it to dry completely before storing it.

WHO IS QUIETGUARD™ FOR?
DISRUPTIVE SNORING

Designed for adults looking for an at-home mouthpiece that may help reduce disruptive nighttime snoring.

PERSONALIZED SHAPE

A good option for sleepers who prefer a mouthpiece that molds around their teeth instead of a standard ready-made shape.

QuietGuard™ is not intended to diagnose, treat, or cure sleep apnea and should not replace CPAP or treatment prescribed by a healthcare professional.

OUR RECOMMENDATION

For hygiene and proper fitting, every sleeper should have their own individually molded QuietGuard™.

FITTING & CARE

How do I fit QuietGuard™?

Follow the included instructions carefully. Heat the mouthpiece as directed, allow it to cool, and mold it around your teeth before first use.

How do I clean it?

Rinse it after each use with cool or lukewarm water and allow it to air dry completely before storing it.

Can I use hot water to clean it?

Avoid hot water after fitting because additional heat may affect the molded shape.

MADE FOR EVERYDAY ROUTINES

Still Relying On Another Coffee?

Long workdays, demanding workouts and busy routines can make it difficult to feel your best throughout the day.

Nualey Flask™ upgrades the water you already drink by generating dissolved molecular hydrogen at the press of a button. There are no powders to mix, tablets to carry or complicated countertop systems to manage.

  • Portable and rechargeable design
  • Dual-chamber SPE/PEM technology
  • One-button hydrogen-generation cycle
  • Backed by a money-back guarantee
Simple setup. No powders or tablets required.
DESIGNED WITH SPE/PEM TECHNOLOGY

Not All Hydrogen Bottles Are Built The Same

The system inside your hydrogen bottle matters just as much as the bubbles you see.

Nualey Flask™ uses a dual-chamber SPE/PEM electrolysis system designed to generate dissolved molecular hydrogen while directing unwanted electrolysis byproducts away from the drinking chamber.

  • Dual-chamber SPE/PEM electrolysis system
  • Designed to separate unwanted byproducts
  • Rechargeable one-button operation
  • Clear glass and brushed-silver construction

Use clean drinking water and follow the included care and operating instructions. Do not add juice, milk, carbonated drinks or other liquids.
