The Halo One is a portable, battery-operated halotherapy device — a "salt therapy machine" — that recreates the salt cave microclimate in your home. It produces a fine salt aerosol you breathe in during a treatment session, supporting respiratory health, skin, and overall wellness. At 9¾ inches long and just 3 pounds, it's small enough to mount inside any Clearlight Infrared Sauna or sit on a shelf in any room up to 10 feet by 10 feet.

Halotherapy is dry salt inhalation therapy. It dates back to the 1840s, when a Polish doctor noticed that workers in the Wieliczka Salt Mines rarely suffered the respiratory issues common to other miners. Modern halotherapy devices recreate the salt cave microclimate in a treatment room. Published research has explored salt therapy's effects on conditions including asthma, COPD, allergies, sub-obstructive adenotonsillar hypertrophy, and various dermatological conditions. Halotherapy is recognized as a complementary wellness modality and is used in spas, wellness clinics, and dedicated salt rooms worldwide.

Most halotherapy devices use grinders or fans that produce relatively large salt particles, which settle in the upper airway before reaching deep into the lungs. The Halo One uses Clearlight's patent-pending Vibrating Mesh Technology: a 3% pharmaceutical-grade saline solution is vaporized through a vibrating mesh that creates micro-sized particles between 1 and 10 microns. Particles in that size range are small enough to travel deep into the bronchioles and alveoli where they have the most therapeutic effect. Per Clearlight, the Halo One is the only halotherapy generator producing salt particles in this size range — and the particle size has been independently tested and certified.

Clearlight frames the benefits of halotherapy across three pillars: skin rejuvenation (regulating pH, supporting natural reparative properties, encouraging collagen production), respiratory health (easing seasonal allergies, reducing congestion, supporting clearer airways), and detoxification (supporting the respiratory system's natural detox processes, helping reduce inflammation and clear blockages). Halotherapy is a complementary wellness practice — results vary from person to person and it works best as part of a consistent routine.

Yes — combining halotherapy with infrared heat is one of the device's signature use cases. The included Sauna Wall Mount attaches to the cabin wall, and the Halo One's internal lithium battery means no cords running through the sauna. There are some important rules: the Halo One can be used inside a sauna up to a maximum of 140°F (60°C) for no more than one consecutive hour, it should be removed after each use if you're running multiple sauna sessions in a day, and it is not designed for continuous in-sauna use.

The included Sauna Wall Mount is sized for Clearlight Infrared Sauna cabin walls. The device itself can be used in other indoor environments (rooms, offices, bathrooms, meditation spaces) as long as the temperature limits are respected, but we don't specifically recommend installing it inside non-Clearlight saunas because the mount and electrical environment are designed around Clearlight's specifications. Talk to a Sauna Republic specialist if you have a specific setup in mind and we'll help you figure out what's safe.

Anywhere indoors, in a room up to 10 feet by 10 feet, with normal humidity levels. Common spots include bedrooms, bathrooms, home offices, meditation rooms, and treatment rooms. Avoid placing it near electronics — the salt aerosol can be corrosive to metal and electronic equipment over time. Keep absorbent materials (carpets, drapes, tablecloths) from becoming damp, and clean room surfaces regularly to remove any salt dust buildup.

One saline cartridge produces approximately 15 to 20 minutes of therapeutic mist, depending on whether you're running the High or Low fan setting. The session ends automatically when the cartridge is empty. You can also pause mid-session by holding the power button for 2 seconds.

Daily use is common for people pursuing respiratory or skin benefits, but the right frequency depends on your goals and how your body responds. Many users start with one session per day and adjust from there. Consistency tends to matter more than session length for cumulative benefits.

Results vary by individual and by what you're using it for. Some users notice respiratory benefits (clearer breathing, reduced congestion) within the first few sessions, while skin and longer-term wellness benefits typically build over weeks of consistent use. Halotherapy is a complementary wellness practice — it's not a one-session fix, it's a routine that compounds over time.

99.99% pure pharmaceutical-grade sodium chloride — the same standard used in hospitals and in the published halotherapy research. No fillers, no caking agents, no additives. The saline cartridges contain a 3% saline solution at this purity level.

No — only use Halo One saline capsules supplied through Clearlight or Sauna Republic. Per Clearlight's safety documentation, using other solutions can damage the device, void the warranty, and may produce adverse health effects. The pharmaceutical-grade purity of the official cartridges is what makes the therapy safe to inhale — substituting other salts (table salt, sea salt, Himalayan salt, etc.) is not safe and not effective.

Refill cartridges are sold separately. Each cartridge produces approximately 15 to 20 minutes of mist (one session). Sauna Republic offers two refill pack sizes — a 30 saline + 2 cleaning starter pack and a 120 saline + 6 cleaning bulk pack. Talk to your specialist about ongoing costs based on how often you plan to use the device, and ask about multi-pack ordering or recurring delivery if you're a daily user or commercial operator.

Both. The Halo One has an internal 5000mAh rechargeable lithium battery for cord-free operation (essential for in-sauna use). The included 45W USB-PD power adapter lets you run it plugged in for extended sessions or to charge the battery. Plug it into any standard household outlet — works on 100–240V AC, 50/60 Hz, so it travels internationally too.

Insert a saline cartridge into the holder, place the holder back into the device, and press the power button to start. The unit runs through the cartridge automatically and stops when it's empty. You can pause mid-session by holding the power button for 2 seconds. There are status indicators on the front for power, saline level, and operating mode. The full sequence is covered in the included user manual and the spec sheet.

The most important rule: clean the water reservoir every 3 days to prevent microorganism growth. Per Clearlight's user manual, the deep cleaning protocol is to drain the reservoir, fill it with 20mL of distilled water mixed with 10 drops of pure white vinegar, run the unit for 3 to 5 minutes, then drain and rinse with clean distilled water before letting it air dry. Wipe the capsule holder opening with a soft cloth and neutral detergent or lukewarm water as needed. Never submerge the device in water and don't touch or push the metal mist outlet nozzle. Cleaning capsules and a saline emitter replacement kit are available for ongoing maintenance.

Halotherapy is a natural complementary therapy, but per Clearlight's official guidance, anyone with the following conditions should consult a doctor before use: infections associated with fever, respiratory system cancers, tuberculosis, cardiac disease, acute respiratory disease, severe hypertension, chronic obstructive lung diseases, or pregnancy. People with serious health conditions or those taking medications should always seek medical advice before starting any new therapy.

Per Clearlight, side effects are typically minimal — the most common are a salty taste in the mouth, mild thirst, or a slightly scratchy throat. These usually pass quickly. If you experience anything more significant or concerning, stop use and consult your doctor.

The Halo One is designed to be quiet during operation — quiet enough for use in a bedroom, meditation room, or sauna without being disruptive. You'll hear a soft hum from the vibrating mesh and fan, but there's no grinding or motor noise like older halotherapy devices.

The Halo One measures 9¾ inches long × 13 inches wide × 4 inches deep and weighs 3 pounds. It's portable enough to move easily between a sauna, a bedroom, and a home office.

The Halo One device, the Sauna Wall Mount, 30 starter saline capsules, 2 cleaning capsules, the 45W USB-PD power adapter, and the product manual. Refill saline capsules (30-count starter or 120-count bulk), cleaning capsules, replacement mesh emitters, the optional Halo One Face Mask, and an extra wall mount kit are all available as separate accessories.

Yes — Clearlight makes an optional Halotherapy Face Mask designed to deliver the salt aerosol more directly to your nose and mouth for focused respiratory treatment. It's sold separately and connects to the Halo One via the included tubing. Useful if you're targeting respiratory benefits specifically rather than general room ambient halotherapy.

The Halo One is built for daily use and the mesh emitter is replaceable, which is what extends device life over the long term. Replacement mesh emitter kits are available so the unit can stay in service for years with regular care. Following the cleaning schedule (water reservoir every 3 days, deep clean as needed) is the single biggest factor in longevity.

The Halo One carries a 1-year limited warranty from Clearlight covering defects in materials and workmanship under normal use. The warranty does not cover damage from misuse, accident, alteration, improper installation, dropped product, transportation damage, environmental conditions, or use of unauthorized accessories or saline solutions.
