At Natural Home Solutions, we specialise in everything from passive vents and EcoFans to comprehensive floor ventilation kits. Whether you choose an underfloor ventilation kit for a simple DIY installation or a fully ducted floor ventilation system installed properly by our team, you’ll enjoy an efficient, quiet, and effective solution.
Features & Benefits
Our sub floor ventilation fans and cross flow ventilation techniques create continuous air movement, replacing damp, musty air with fresh air from outside.
By addressing ground moisture and damp air, our ventilation systems remove the conditions that encourage mould and mildew growth.
Effective floor ventilation lowers the risk of timber rot and discourages termites, which thrive in damp, enclosed spaces.
Reducing sub floor humidity lessens the load on your HVAC system.
Choose from our sub floor ventilation kits—perfect for DIY installation—or engage our experts for a fully customised ventilation system with ducting, inline fans, and smart controls. Whatever your floor area, we have a solution to fit.

Why Proper Installation Matters
Choosing the right sub floor ventilation system isn’t just about moving air—it's about selecting proven products built for the climate and conditions we face in Australia. Without a well-planned layout that considers airflow dynamics, the result is often ineffective movement of air, leading to persistent damp air, humidity, and even structural deterioration.
At Natural Home Solutions, we approach every floor ventilation system with care and precision. We evaluate your property’s unique layout, moisture levels, and floor area to design a system that supports cross ventilation—maximising fresh air intake and stale, moist air exhaust. Whether it’s through inline fans, ducted systems, or strategically positioned vents, we ensure the air moves continuously across the entire sub floor, not just around the edges.
Correct installation is key to performance. Our expert technicians ensure every unit, fan, and vent is installed properly to support continuous, balanced airflow across your floor space. We account for cross ventilation, passive vent placement, and structure layout to prevent stagnant air pockets. It’s not just about plugging in a fan—it’s about implementing a comprehensive system that delivers lasting results and peace of mind.
Targeted Mould Prevention & Moisture Control
The primary culprit behind most damp problems in homes is poor subfloor ventilation. When ground moisture rises unchecked into your floor space, it creates a humid environment perfect for mould, mildew, and wood decay. This isn’t just an issue of aesthetics—mould exposure can lead to serious health complications, especially for children, the elderly, or those with respiratory conditions.
That’s why our sub floor ventilation fans, like those in the EcoFan range, are specifically designed to pull damp, stale air from the floor space, replacing it with fresh air from outside. These fans run continuously or on timed intervals, depending on your environment, to keep the airflow constant and consistent. When combined with passive vents and smart ducting, we create a full ventilation system that targets hidden areas and promotes cross flow ventilation. Our aim is to eliminate moisture before it becomes a problem, helping you avoid costly mould remediation and keeping your home structurally sound and healthy year-round.
Frequently asked questions
Passive vents rely on natural air currents to move fresh air in and stale air out, using no power. Floor ventilation fans (including inline fans) actively force airflow and often include timers or humidity controls for targeted operation.

The number depends on your floor area, the level of ground moisture, and local building codes. We calculate the required air changes and recommend the right number of ventilation openings, fans, or a hybrid system.
While ventilation alone can’t solve all rising damp issues, it significantly reduces damp air levels and ground moisture, slowing the spread of moisture through walls and floorboards when combined with drainage and damp-proofing measures.
Our floor ventilation fans and inline units are selected for their quiet operation. When installed properly and with the right capacity, most homeowners report barely noticing the system running, even on higher settings.
