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.

How do I know what dehumidifier capacity I need?

Dehumidifier capacity is measured in litres removed per day. Small rooms need 10-20 litre capacity, medium spaces require 20-30 litres, and large areas need 30+ litre capacity. Consider your climate and moisture levels; humid coastal areas need more powerful units.

How much noise do air purifiers and dehumidifiers make?

Noise levels vary by model and speed settings. Most air purifiers operate between 25-60 decibels, with low settings that are whisper-quiet for bedrooms. Dehumidifiers typically range from 40-55 decibels. Product pages often list decibel ratings. If you're noise-sensitive, look for models with sleep modes.

Are these appliances energy efficient?

Modern units are increasingly energy-efficient, though consumption varies by model. Air purifiers typically use less electricity than dehumidifiers. Look for Energy Star ratings or models highlighting efficient operation. Dehumidifiers with auto-shutoff at target humidity save energy. You can check power consumption specifications on each product page.

Can I check if specific models are available at my local Myer store?

Yes. Use the "Find in Store" feature on any product page to check real-time availability at your nearest location. Due to their size, not all stores display the complete range. You can also use Click & Collect to purchase online and pick up in-store.
