WHAT IS COLD-AIR DIFFUSION?
WHAT IS COLD-AIR DIFFUSION?
Cold-air diffusers disperse fragrances through nebulization—a process that breaks down scent oils into an ultrafine dry mist. The nanoparticles in this mist are so tiny that they remain suspended in the air for hours and leave no residue. This cutting-edge technology uses no water, alcohol or heat, diffusing scents in their purest form.
WHY IS IT BETTER?
WHY IS IT BETTER?
Cold-air diffusers can cover spaces twice as large as typical candles, reed diffusers, plug-ins and ultrasonics. They’re more consistent, ensuring fragrance is evenly distributed, and more precise, giving you the option to adjust the scent intensity. They’re also cleaner: Because our diffusers neither dilute nor heat the scent oil, they preserve each formulation’s integrity.
COLD-AIR VERSUS ULTRASONIC
COLD-AIR VERSUS ULTRASONIC
No water, no mold, no residue, no clouds of vapor—our cold-air diffusers have a number of benefits over traditional ultrasonics. They’re more powerful and use diffuser oils more efficiently, so your scents last longer. They’re also far easier to use: you can go months between refills, and no hands-on cleaning is required. In fact, a quick rinse with our cleaning solution is the only maintenance recommended.

Questions? We’ve Got You Covered
What is this diffuser?
It's a silent (under 38dbA), waterless aromatherapy device crafted from aluminum alloy. It uses cold-air diffusion to atomize pure essential oils directly from a 120ml bottle, effectively scenting areas up to 200m³, controllable via a smart remote.
How do I set up?
First, ensure power is off. Unscrew the cap and dropper from your 120ml oil bottle, then screw the bottle tightly directly into the diffuser's atomizer. Plug in the device, and use the remote control to power it on and adjust settings.
How do I clean it?
Exterior: Wipe the exterior with a soft, dry cloth.
Atomizer Cleaning: If scent output diminishes or you change oils, unscrew the oil bottle, then screw in a bottle of pure rubbing alcohol (isopropyl alcohol) into the atomizer. Run the diffuser on a low setting for 10-15 minutes in a well-ventilated area to clear residue. Remove the alcohol bottle and allow the atomizer to air dry completely before reinserting your essential oil. If issues persist, the atomizer core might need replacement (refer to device instructions).
Oil bottle lifespan?
The lifespan depends on your usage (intensity and duration). At moderate settings, a 120ml bottle typically lasts from several weeks to over a month of regular use. Replace it when the scent significantly diminishes or stops.
Warranty details?
The diffuser comes with a 12-month limited warranty from the purchase date, covering defects in materials and workmanship under normal use. To make a claim, contact our customer support at contact@hiigieia.com with your order number, purchase invoice, and a description of the issue.
Warranty exclusions?
The warranty excludes damage from accidents, fire, improper use/operation (e.g., prolonged non-stop operation), unauthorized repairs, missing warranty tags, improper cleaning, or use of non-original parts/machines not from official channels.
Troubleshooting Tips
No/weak scent?
Check power, remote settings, oil bottle connection/seal, and oil level. Atomizer might be blocked; try cleaning.
Leaking oil?
Ensure oil bottle is screwed in very tightly and its seal is intact. Check atomization connector. Diffuser must be on a flat, stable, and upright surface.
