Revolutionize Your Space with Cold-Air Diffusers

Cold-air diffusion technology (also known as nebulizing technology) is a method used to disperse fragrances into the air without using heat, water, or evaporation. This technology preserves the integrity and therapeutic properties of the oils, ensuring a consistent and pure scent experience. On average, our diffusers cover twice the square footage of ultrasonic diffusers or candles.

Cold-air VS. Ultrasonic Diffusion

Cold-Air Diffusion excels in preserving oil integrity, covering large areas, operating efficiently, and minimizing residue or mold risk, making it a superior choice for fragrance oil diffusion in many aspects. On average, our diffusers cover twice the square footage of ultrasonic diffusers or candles.

What is a cold-air diffuser?

A cold-air diffuser uses nebulizing technology to disperse fragrance oils into the air without using heat or water. This is accomplished through a high-velocity, pressurized airstream and jet nozzle. The microscopic particles in the mist remain suspended in the air for hours. This method preserves the fragrant properties of the oils, diffusing scents in their purest form.

On average, our diffusers cover twice the square footage of ultrasonic diffusers or candles.

How does a cold-air diffuser work?

Cold-air diffusers (also known as nebulizing diffusers) draw in air, which is then filtered and passed through a nebulizer. The fragrance oil is broken down into microscopic particles, creating a fine, dry mist that is released into the air.

What are the benefits of using a cold-air diffuser?
  • Low Maintenance: Cold-air diffusers are easy to clean and maintain, as they do not produce residue or require frequent refills.
  • Preserves Oil Integrity: No heat means the fragrance oils retain their properties.
  • Efficient: Uses less oil to scent larger areas.
  • Consistent: The level of diffusion remains constant throughout the entire usage period, regardless of how much fragrance oil is left in the bottle.
  • Clean: No residue or mold buildup.
  • Coverage: Effective for large spaces.
  • Safety: Cold-air diffusers do not use heat, alcohol or water, making them safer to use.
How do I maintain a cold-air diffuser?

Regular maintenance involves cleaning the diffuser by running it with a bottle of alcohol for about 15 minutes to remove any residue. Always follow the user manual.

Do cold-air diffusers require a lot of power?

No, cold-air diffusers are energy-efficient and do not require a lot of power to operate.

Can cold-air diffusers be used in HVAC systems?

Yes, some cold-air diffuser models are designed to be integrated with HVAC systems, allowing for whole-house or large-area scenting.

Are cold-air diffusers safe to use around children and pets?

Yes, cold-air diffusers are safe to use around children and pets. However, it’s important to keep the diffuser out of reach of curious hands and paws to prevent accidents.

All our fragrance oils are IFRA and RIFM compliant. They adhere to the highest safety standards in the industry. They are safe to use around people, pets, and plants.
