Air Handler Bio-Clean Gel 250g Trade Pack

Made for central air conditioning (ducted HVAC air handlers)

In ducted or central air systems, a large volume of air circulates through the air handler and ducting every day. Over time, build-up inside the system can contribute to stale airflow, musty smells, and airborne irritants moving through the home.

This 250g trade pack gel is designed for use with central air conditioning / HVAC air handlers to support cleaner system hygiene and fresher-feeling indoor air.

Why it matters for families

Mould exposure can aggravate asthma and allergies, especially in children. Improving HVAC hygiene and reducing airborne mould and germs can help support a healthier indoor environment for your whānau.

Musty odours can also be an early sign of hidden mould in damp areas of the system. Supporting cleaner airflow helps you stay ahead of issues before they become obvious.

What it helps with

• Cleaner, fresher airflow: supports a cleaner-feeling indoor air experience in ducted homes and buildings.
• Musty system smells: helps reduce stale odours linked with build-up inside the air handler.
• Airborne hygiene support: helps reduce airborne bacteria, germs and mould spores as air circulates.
• High-use environments: ideal where systems run often — family homes, accommodation, offices and facilities.

Best for

• Central air conditioning (ducted HVAC systems)
• Air handlers and return air environments
• Family homes and high-occupancy living
• Accommodation providers and shared spaces
• Offices, clinics, gyms and facilities

How to use

• Use as directed for HVAC/air handler placement and servicing processes.
• For best results, clean/replace filters and address visible build-up first.
• Use as part of routine maintenance to support ongoing indoor air hygiene.

Tip: If you notice a persistent musty smell from vents, it’s worth checking filters, condensate drains, and damp areas inside the system — then use this product to help maintain freshness between services.
