Heat Pump & Split System Purifier Gel 15g

Made for heat pumps & split-system air conditioners

If your heat pump smells musty when you turn it on, it’s usually coming from inside the indoor unit — where air, moisture and dust can combine over time.

Heat Pump & Split System Purifier Gel 15g is designed to support cleaner internal hygiene and fresher-feeling airflow by helping reduce the sources of stale odours and airborne contaminants as the unit runs.

Why it matters for homes

Musty odours can be an early sign of hidden mould inside damp parts of the unit. Staying on top of heat pump hygiene helps you stay ahead of problems before they become obvious.

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

What it helps with

• Musty heat pump smell: helps reduce stale odours coming from the indoor unit.
• Fresher airflow: supports cleaner-feeling indoor air when the system is running.
• Airborne hygiene support: helps reduce airborne bacteria, germs and mould spores as air circulates.
• Great between services: works best alongside filter cleaning and routine maintenance.

Best for

• Heat pumps (wall-mounted split systems)
• Split-system air conditioners in bedrooms and living spaces
• Homes where the unit runs often (winter heating / summer cooling)
• Rental properties and accommodation with frequent guest turnover

How to use

• Use as directed for placement inside/near the indoor unit (split system air handler).
• For best results, clean or replace filters first and wipe visible dust/moisture build-up where accessible.
• Use as part of routine upkeep to support fresher airflow between professional services.

Tip: If the smell is strong, start with a proper clean (filters + coil/condensate areas) or a service, then use this product to help maintain freshness.
