Mould is a major health concern in Australian homes, but cleaning the visible growth on walls is only half the battle. If you still smell that persistent musty odour or continue to experience allergy and asthma symptoms, the true culprits are the invisible mould spores that remain suspended in your air.
To truly safeguard your health and your home, you need a comprehensive strategy that tackles both the airborne threat and the root cause. This is the ultimate "Mould Lockdown" provided by Ionmax's 2-in-1 Dehumidifier and Air Purifier models (like the Leone Pro, Rhine Pro, and Venta).
🥊 Punch 1: The dehumidifier (eliminate the source)
Mould cannot survive without water. It only takes a few days of consistent humidity for spores to germinate and visible growth to begin. The dehumidifier's job is purely preventative: it deprives mould of the moisture it needs to live.
The critical humidity threshold
- Mould thrives when indoor relative humidity (RH) is consistently above 60%.
- The National Asthma Council (NAC) of Australia and many health bodies recommend keeping humidity between 40% and 50% for optimal health and allergen control.
- The dehumidifier automatically monitors the air, actively pulling out excess moisture to maintain this safe, dry range.
By controlling moisture in high-risk zones like laundries, basements, and bedrooms with ensuites, the dehumidifier ensures that spores simply cannot colonise new surfaces.
🥊 Punch 2: The air purifier (capture the invisible threat)
While the dehumidifier stops growth, the integrated Air Purifier function neutralises the existing health threats in the air.

Capturing spores with an Antiviral H13 HEPA Filter
Mould spores, along with other key triggers like dust mites and pet dander, are airborne particles.
- Mould spores typically range from 1 to 5 microns in size.
- Your Ionmax 2-in-1 units feature an Antiviral H13 HEPA filter. This is certified to capture 99.97% of particles as small as 0.3 microns.
- This superior filtration makes the H13 HEPA filter extremely effective at trapping microscopic spores and preventing them from being inhaled, offering peace of mind to allergy and asthma sufferers. By continuously removing these airborne particles, the unit also helps reduce that stagnant, musty air quality.
By combining these two technologies, you create a complete defence: the dehumidifier kills the root cause, and the HEPA filter removes the invisible threat.
✅ Your Mould Lockdown Action Plan
Follow these simple steps using your Ionmax 2-in-1 model for comprehensive mould control:
- Clean First: Physically remove any visible mould with a cleaning solution (and ensure the area is dried).
- Set the Target: Set your unit's humidistat to maintain an RH level of 45–50%.
- Run 24/7: Allow the 2-in-1 appliance to run continuously in auto or laundry mode to keep the air dry and clean.
- Check Filter Health: Regularly check and replace the HEPA and Activated Carbon filters as scheduled. This ensures captured spores are contained and the purification remains effective.
