What Works for Moulds? Dehumidifiers, Air Purifiers or Both?

Mould is a houseowner’s nightmare. 

Regular cleaning can tackle surface mould, but preventing airborne spores from spreading requires more advanced solutions. That’s why devices like air purifiers and dehumidifiers are sought after to protect homes and other social spaces. 

But which one should you invest in? A dehumidifier or an air purifier? Or is a combination the best approach? 

Let’s break it down for you. 

Is the Australian Climate Conducive to Mould Growth?

Common mould types found in Australia include Cladosporium, Aspergillus, Penicillium, Serratia marcescens, and the more hazardous Stachybotrys chartarum (black mould). These grow on walls, ceilings, fabrics, air conditioners, and even food. Stained with their yellow, green, black and sometimes even pink hues, they go unnoticed until health symptoms arise or surfaces become visibly mouldy.

Coastal and tropical Australia have ideal conditions for mould. High rainfall, humidity, and warm temperatures lead to condensation and dampness, especially in poorly ventilated rooms, creating the perfect petri dish of nutrients for mould growth. 

In Northern Queensland, Sydney’s beachside suburbs, and parts of Melbourne, many households report seasonal or ongoing mould issues.

Modern homes built for energy efficiency often limit natural ventilation, unintentionally trapping moisture inside, making it easier for mould to spread on walls, ceilings, upholstery, and even inside HVAC systems.

What Is the Health Impact of Mould on Children, Pets, Adults, and Seniors?

Mould can pose serious health risks for vulnerable individuals. Here’s a list of how mould impacts adults, kids, and seniors. 

Which Works Better? Dehumidifiers, Air Purifiers or Both?

To combat mould effectively, it helps to understand the difference between air purifiers and dehumidifiers. Here’s a comparison:

If you live in a humid climate or have recurrent mould issues, both devices together offer the best results. The dehumidifier prevents moisture that fuels mould, while the air purifier for mould filters the spores from the air.

What Makes the Airdog Air Purifier Range Good for Mould Remediation?

The Airdog range of air purifiers is uniquely suited for tackling airborne mould challenges in Australian homes. Here’s why:

• Advanced TPA Filtration

Airdog uses patented TPA technology, which removes 99.9% of airborne pollutants, including mould spores, down to an ultrafine 0.0146 microns. That’s far smaller than what traditional HEPA filters can catch.

• Washable Filter System

Unlike many air purifiers for mould and bacteria that require frequent filter replacements (HEPAs), Airdog’s filters are washable and reusable, so they’re more eco-friendly and cost-effective in the long term.

• Odour and VOC Removal

Mould often comes with a musty odour. Airdog units are equipped to remove unpleasant smells and volatile organic compounds (VOCs) commonly associated with damp areas.

• Smart Air Monitoring

Airdog air purifiers constantly monitor air quality and adjust fan speed in real-time, making sure your indoor air stays clean and healthy without manual intervention.

• Pet and Child Safe Design

With built-in safety locks and automatic shutoff when the back panel is opened, they’re designed for homes with curious pets and children.

Buy Air Purifier for mould and bacteria

While a dehumidifier works best at preventing mould in high-humidity areas, pairing it with an air purifier for mould and bacteria ensures any airborne spores are captured before they can settle and grow again

Investing in both may seem like a big step, but when it comes to your family’s wellbeing, clean air and dry spaces are absolutely worth it.
