onmax is a brand owned and operated by Andatech Pty Ltd, an Australian company based in Vermont, Victoria. The brand specializes in indoor air quality appliances such as air purifiers, dehumidifiers, humidifiers, heaters, and related accessories.

Ionmax offers a variety of indoor air treatment appliances, including:

• HEPA + UV / UVGI air purifiers with multi-stage filtration systems
• Desiccant dehumidifiers (rotor / adsorption type) designed to remove moisture and prevent mold/mildew
• Humidifiers (especially ultrasonic UV/humidifier models) for adding moisture to dry air
• Portable / wearable ionic purifiers (e.g. ION260 personal air purifier)
• Hybrid models and industrial grade units (e.g. Ionmax+ ED18, which functions as a desiccant dehumidifier and also supports HEPA filtration)

Indoor air often contains pollutants such as dust, pet dander, mould spores, volatile organic compounds (VOCs) from household products, and allergens.

Because people spend a large amount of time indoors, having a device to help remove or reduce these contaminants can improve respiratory comfort, reduce allergy or asthma triggers, and generally support healthier indoor air.

Many Ionmax dehumidifiers use a desiccant rotor (adsorption) mechanism. In these units, a desiccant material (e.g. zeolite) adsorbs water vapor from the air. The moisture-laden desiccant is then regenerated (i.e. dried) by a flow of warm air, and the process repeats.

Because of this approach, their dehumidifiers perform relatively consistently across a wider range of temperatures (compared to standard compressor dehumidifiers), and can reach lower humidity levels. Some models also include “laundry mode” to help dry indoor clothes and silver-nano filters to reduce bacteria growth.

It depends on the model and how heavily you use it, but in general the filters should be checked every few months and replaced (or cleaned if washable) every 6–12 months for optimal performance.

Some newer models have filter indicator lights or app notifications to tell you when to change filters.

According to Ionmax’s support documentation, their air purifiers are not ozone generators. The “ioniser” or negative ion features do not intentionally produce harmful levels of ozone.

Some models may produce trace amounts of reactive ions, but not to levels considered harmful under normal usage.

CADR stands for Clean Air Delivery Rate. It is a standardized metric that describes how much filtered air an air purifier can deliver per unit time (for example, for dust, pollen, and smoke). A higher CADR generally means faster or more effective cleaning in a space. It helps you match an air purifier to the size of the room you want to treat.

Yes, many Ionmax units are designed to run continuously. They often include features like timers, speed management, and safety protections.

It is generally safe, provided you follow the user manual, maintain filter cleanliness, and ensure adequate ventilation.
