Airscent Beta HVAC Waterless Diffuser (Black, 500ml)

How does the cold air diffusion technology work?

The system uses twin fluid atomisation to break essential oils into microscopic dry particles without heat or water. Compressed air forces oils through a specialised nozzle creating a fine mist that preserves the molecular structure of fragrances. These particles remain airborne for hours and distribute evenly throughout spaces without leaving residue on surfaces.

Can this diffuser connect to any HVAC system?

Yes, the unit integrates with most residential and commercial HVAC systems through ductwork installation. You'll need to cut a hole in the supply duct and insert the dispensing tube past the blower motor in the direction of airflow. The system works with forced air heating, cooling and ventilation systems that have adequate airflow capacity.

What is the coverage area and how long does the fragrance last?

The diffuser effectively scents areas up to 5600 square feet depending on ceiling height and ventilation. Fragrance intensity varies based on oil type and diffusion settings. Most users report noticeable scenting for 2-4 hours after each cycle, with micro-particles continuing to provide subtle fragrance for extended periods.

How much essential oil does it use and how often do I need refills?

Oil consumption depends on your programmed settings and usage frequency. The 500ml reservoir typically lasts 1-3 months with moderate use. The mobile app calculates consumption based on your settings and sends refill notifications. Running the unit continuously at maximum intensity will require more frequent refills than scheduled intermittent operation.

Is the unit noisy when operating?

The diffuser operates quietly with minimal noise from the internal air compressor. Most users report it's barely audible during normal operation. The sound level is comparable to a small aquarium pump or computer fan. When connected to HVAC systems, any operational noise is typically masked by the furnace or air conditioning unit.

What type of essential oils can I use with this diffuser?

The system works with most pure essential oils and fragrance oils designed for commercial diffusers. Avoid thick oils, water-based fragrances, or oils with high viscosity that may clog the atomisation system. Airscent recommends their proprietary oil blends for optimal performance, but many third-party oils work effectively with proper viscosity.

How do I clean and maintain the diffuser?

Regular maintenance involves wiping the exterior with a damp cloth and occasionally cleaning the oil reservoir with isopropyl alcohol. The atomisation chamber may require periodic cleaning if you notice reduced output. Replace the internal air filter every 3-6 months depending on usage. The unit includes detailed maintenance instructions and troubleshooting guides.

Can I use this as a standalone unit without HVAC connection?

Absolutely, the diffuser functions effectively as a standalone unit for rooms or areas without HVAC integration. Place it on a stable surface with adequate ventilation around the unit. Standalone operation works best in spaces up to 1000 square feet, though larger areas may receive lighter scenting depending on air circulation patterns.
