Air Purifiers & Dehumidifiers

What is the difference between an air purifier and a dehumidifier?

Air purifiers improve air quality by filtering airborne particles like dust, pollen, pet dander, and smoke through HEPA or carbon filters. Dehumidifiers extract excess moisture from the air, preventing mould growth and musty odours. Some households benefit from both devices for comprehensive air comfort.

How do I choose the right size air purifier for my room?

Air purifier capacity is measured by room size in square metres, specified on product pages. Measure your room's dimensions and choose a purifier rated for that size or slightly larger. For open-plan spaces, choose more powerful units or multiple purifiers for optimal air cycling.

What brands of air purifiers and dehumidifiers does Myer stock?

Myer offers trusted brands known for air quality technology. Our range includes compact units for bedrooms to powerful systems for larger living areas with various filtration technologies and features like smart controls.

How often do I need to replace air purifier filters?

HEPA filters typically last 6-12 months with regular use, while activated carbon filters may need replacing every 3-6 months. Pre-filters require monthly cleaning or replacement. Most modern purifiers feature filter replacement indicators that alert you when maintenance is needed.

Are air purifiers effective for allergies and asthma?

Yes. Quality air purifiers with true HEPA filters capture 99.97% of airborne particles as small as 0.3 microns, including common allergens like pollen, dust mites, pet dander, and mould spores. Models with activated carbon filters also eliminate odours and chemical vapours.
