When you exhale, your breath contains natural moisture. Our patent-pending design captures and stores this moisture in the HME filter. When you inhale, dry cabin air passes through the humidified matrix, picking up moisture before reaching your respiratory system. This creates a continuous cycle of moisture exchange.

No batteries. No refills. Just your body's natural humidity working for you.

Yes! Many customers report feeling the difference even on 1-2 hour flights. Cabin humidity drops to low levels within minutes of takeoff, so your throat and nasal passages benefit from protection on any flight. Think of it as sunscreen for your respiratory system, protection matters regardless of exposure duration.

HME (heat moisture exchange) technology has been used in medical settings for years.

Our patent-pending design represents years of Swedish engineering to create something that actually works in the unique environment of airplane cabins.

Absolutely! While designed for aviation, many customers use Kuvola in:

• High-altitude destinations (ski resorts, mountain travel)
• Desert climates (Dubai, Las Vegas, Arizona)
• Air-conditioned hotels or offices
• Anywhere dry air affects your comfort

The moisture exchange technology works anywhere you need respiratory humidification. Learn more about Kuvola.

The soft, medical-grade materials are designed to minimize pressure marks. Unlike hard plastic or rigid masks, Kuvola's flexible design distributes pressure evenly.

While any face-worn product might leave temporary slight impressions, these typically fade within 10-15 minutes of removal. For important arrivals (business meetings, events), simply remove the mask 15-20 minutes before landing to let your skin recover fully.

Yes. Comfort for extended wear was our primary design goal. The soft, medical-grade materials don't irritate skin, the ergonomic shape prevents pressure points, and the moisture exchange actually makes breathing more comfortable over time (unlike regular masks that trap heat). The adjustable head strap allows you to find your perfect fit.

Kuvola is designed to fit approximately 95% of adult face sizes. The adjustable head strap and flexible medical-grade materials conform to different face shapes.

Our ergonomic design accommodates everything from petite faces to larger builds.

The soft head strap fits comfortably without irritating.

A standard cloth face mask is designed to prevent the users from spreading germs.

Kuvola is designed to provide optimal humidity. It uses patent-pending moisture exchange technology.

Kuvola's medical-grade HME foam matrix captures moisture from your exhaled breath and uses it to humidify the air you inhale.

Many travellers say Kuvola helps make sleeping on planes feel easier. In low-humidity cabins, the device is designed to reduce the sensation of dry mouth or scratchy throat during flight.

With its lightweight, secure fit and soft materials, it stays in place without irritating skin during rest.

On long red-eye flights, users often report arriving less affected by dryness and more ready to go.

Yes! Kuvola is designed to fit all adults comfortably and look great, regardless of gender.

Universal fit features:

• Adjustable head strap accommodates different head sizes.
• Flexible, ergonomic, medical-grade materials conform to various face shapes.

No. Kuvola is designed for unrestricted airflow. You breathe normally through the mask, just with humidified air.

Unlike N95 masks that create resistance, our design prioritizes comfort and easy breathing.

If you can breathe comfortably through your nose and mouth normally, you'll have no issues with Kuvola. In fact, most users report breathing feels easier because the moisture soothes rather than irritates airways.

Kuvola is designed with sleek, minimalist Swedish aesthetics—it looks more like premium tech than medical equipment.

In the post-pandemic era, masks are normalized on flights, and many travelers now wear them for privacy and health.

It's no different to wearing an eye mask or using a neck pillow.

Plus, arriving refreshed is worth any momentary self-consciousness. As one customer said: "I'd rather look prepared than feel terrible."

Yes! Kuvola sits lower on the face than standard masks, so it doesn't interfere with glasses.

Unlike masks that cause glasses to fog, Kuvola's design directs airflow away from your eyes. Many customers specifically appreciate this feature for reading or working during flights.

⚠️ IMPORTANT: Kuvola contains magnets and should NOT be used by anyone with electronic medical implants.

Do not use Kuvola if you have:

• Pacemaker
• Implantable cardioverter defibrillator (ICD)
• Neurostimulator or spinal cord stimulator
• Cochlear implant
• Insulin pump or glucose monitor with magnetic components
• Any other electronic medical implant

Why: The magnetic head strap attachment system may interfere with the operation of electronic medical devices, which could be dangerous or life-threatening.

If you're unsure: Consult your cardiologist or device manufacturer before using Kuvola. Your safety is our top priority.

For all other users: Kuvola is safe when used as directed. The magnets are contained in the head strap clip and do not come into direct contact with skin or airways.

No.

Kuvola contains strong magnets in the head strap attachment, which can interfere with pacemakers and other electronic medical implants. This interference could cause your device to malfunction, which may be dangerous or life-threatening.

If you have a pacemaker, ICD, neurostimulator, cochlear implant, or any other electronic medical implant, do not use Kuvola.

We take customer safety extremely seriously. While we'd love for everyone to experience the benefits of Kuvola, your health and safety come first. Please consult with your cardiologist or device manufacturer about alternative travel comfort solutions.

Customer feedback:
Many frequent travelers report that since using Kuvola, they experience:

• Fewer post-flight sore throats
• Less post-travel fatigue
• Better overall travel wellness
• Reduced "airplane hangover"

Why this might happen:
When your respiratory system stays properly hydrated, your body's natural defenses can work optimally. Dry, irritated airways are more vulnerable to all kinds of issues—from infections to inflammation.

However: We cannot claim that Kuvola prevents illness. Many factors affect whether you get sick during travel (exposure level, your immune health, sleep, stress, etc.).

What we can say: Maintaining hydrated airways is generally beneficial for respiratory health, and most travelers report feeling better overall when they arrive at their destination.

This is not medical advice. If you have specific health concerns, consult your physician.

Yes. Kuvola is simply a moisture delivery system with no medications, chemicals, or active ingredients. As always, consult your healthcare provider about any travel-related concerns.

Kuvola is designed for adults (ages 18+) and is not recommended for children.

Important safety information:

⚠️ CHOKING HAZARD: Kuvola contains small parts (including magnetic components) that may pose a choking hazard to children or infants. Do not allow children to play with Kuvola or its components.

No. Kuvola is a personal comfort and wellness device, not medical equipment.

What this means:

• Not intended to diagnose, treat, cure, or prevent disease
• Not a substitute for medical advice or treatment
• Not PPE (Personal Protective Equipment)

It is not necessary to clean after every flight. Simply clean when you feel it is time.

• Unclip the outer shell (see the guide included in your delivery)
• Remove the foam insert
• Hand wash both the mask shell and foam with mild soap and warm water
• Rinse thoroughly
• Foam may expand in water, air dry completely before next use (4-6 hours)

Never use bleach, hot water above 40°C/104°F, or put it in the washing machine/dryer.

Yes! With proper care, Kuvola lasts for 100+ flights.

The durable medical-grade materials are built to withstand regular use and washing.

The foam insert is the first component that may need replacement. We offer replacement foam inserts separately if needed. Many frequent flyers have been using the same Kuvola for 50+ flights and counting.

Yes. Like reusable water bottles or glasses, regular washing maintains hygiene. The medical-grade materials are naturally antimicrobial and designed for repeated use and cleaning. Each wash removes bacteria, dust, and other particles. Many customers are more comfortable with a clean, personal Kuvola than touching shared airplane surfaces.

Drinking water helps with overall hydration, but it doesn't solve respiratory dryness. Your mucous membranes dry out with every breath in the 5%-12% humidity cabin air.

Travelers may lose up to 2 liters of water through breathing alone on long flights.

You'd need to drink constantly (and then deal with frequent bathroom visits) to stay properly hydrated.

Kuvola is engineered to make long-haul travel more manageable by helping retain moisture in the air you breathe, so you don’t have to rely solely on nonstop water intake.”

Regular masks are not designed to humidify incoming air. In fact, many people find regular masks make breathing feel more difficult on long flights. Kuvola's patent-pending moisture exchange system is specifically designed to humidify air you inhale while remaining comfortable for 8+ hours. They're fundamentally different technologies.

Nasal sprays provide temporary relief but require repeated application throughout the flight.

Kuvola provides continuous humidification for your entire respiratory system (nose, throat, lungs)—not just nasal passages.

Many travelers use both: saline spray for initial relief, then Kuvola for ongoing protection. Think of it as comparing hand sanitizer (temporary) vs. wearing gloves (continuous protection).

Each Kuvola purchase includes:

1. Kuvola® Humidifier Mask (main unit)
2. Medical-grade moisture exchange foam insert
3. Adjustable magnetic head strap
4. Premium travel pouch with carabiner clip
5. Quick-start instruction card
6. Cleaning and care guide
7. Safety Warnings

Everything you need to start traveling in comfort.

No. For hygienic reasons, Kuvola cannot be returned once the seal has been broken.

Why this policy:
Kuvola comes sealed to ensure you receive a completely new, unused product. Once opened and used (in contact with your face and breath), it cannot be resold for hygiene and safety reasons—similar to earbuds, face masks, or other personal hygiene products.

Quality issues:
If you experience any manufacturing defects or quality problems after opening, contact us at support@kuvola.com. We'll work with you to resolve the issue, which may include replacement or credit, depending on the circumstances.

Not yet, but soon! Currently, Kuvola is primarily available through our website to ensure quality control, competitive pricing (no retail markups), and direct customer support.

We're exploring select retail partnerships for the future.

Buying direct also ensures you're getting the genuine product with our 30-day guarantee—we've seen counterfeit products in some third-party marketplaces.

Yes. Kuvola is REACH certified, meeting strict European Union safety standards for chemical substances in consumer products.

What is REACH certification?

REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) is one of the world's most comprehensive chemical safety regulations. It ensures that products sold in the EU:

• Contain no harmful substances above safe limits
• Use materials safe for extended skin and respiratory contact
• Meet strict environmental and health protection standards
• Are tested and documented for consumer safety

Why this matters for you:

REACH certification means every material in Kuvola—from the medical-grade foam to the fabric and magnetic components—has been evaluated for safety when in contact with your skin and respiratory system.

This is especially important for a product you wear on your face for 8+ hours at a time.
