Humidifiers, air purifiers & dehumidifiers

Humidifiers, purifiers and dehumidifiers in Australia

Updated 4 November 2026

In Australia a humidifier, air purifier or dehumidifier costs about A$72 to A$600 right now, depending on size and brand. A small 2 L dehumidifier for one room is the cheapest option, while premium 2-in-1 units cost several hundred dollars. For a price that fits your room, post a request on BlaBlaPrice, and the AI will check local sellers' websites and price lists.

Warranty and what to check

Warranty terms differ between brands. Search results show a 2-year warranty and 30-day returns on Philips air purifiers, 2 years on an Australian-designed brand, and 12 months on Daikin air purifiers bought in Australia. Ask the seller to confirm the warranty period in writing before you pay, and check how often the filter must be replaced, since one Philips listing gives a filter life of 3 years.

Season: summer heat and winter damp

Buying in November gives you the unit before summer, which runs from December to February. Winter, from June to August, brings damp and mould to many Australian homes, so a dehumidifier is best ready by autumn, before the cold months. A humidifier is more useful in the dry air of winter, when heating runs for long hours.

Delivery and how prices are quoted

Ask for delivery to your city, which can be Sydney, Melbourne, Brisbane, Perth or Adelaide, and for the total price, because delivery fees differ. Capacity is written in litres (2 L, 12 L, 25 L) and room coverage in square metres, so measure your room in m² before you compare. Some listings show "incl." next to the price, so check whether GST is included.

What to put in your request

Start with the device type: dehumidifier, humidifier, air purifier or a 2-in-1 unit. Add the room area in m², the main purpose (damp, dust or allergies), the filter or technology, the capacity in litres, and whether you want new or used. If the room has no floor drain, say so, because most dehumidifiers collect water in a tank you must empty. State your budget in A$ and your city, so that sellers can quote the right price and delivery.
