The Black Friday deals season is one of the best times to buy a Dyson tower fan. The British company’s fans, which sport a unique belted style and handy smart features, are typically sold at a high price – sometimes costing over AU$1,000! But with the Black Friday bargains, we’ve seen the costs come down dramatically.

The most impressive discount we’ve seen this year has been an all-time low price for the Dyson Purifier Cool, the company’s tall cooling fan that doubles as a HEPA-filtered air purifier.

But a Dyson fan (pun alert!) will tell you that there’s more to fans than just cooling; fans that can sense airborne particles, including formaldehyde that can be emitted by several household items like new furniture, along with fans that double as heaters are on offer – and even though we’re heading into summer, a heating fan may be attractive once we head into winter in 2025. Different sizes, along with options that come with features through the MyDyson app, are available if you so wish.

So let’s quit rambling – if you’re looking for a Dyson fan to beat the summer heat, this is your one-stop article.

This Dyson appliance offers heating, cooling and air purification, making it more space-efficient than investing in separate devices.

It’s a rather expensive device, but it looks modern and sleek, and the all-in-one aspect is appealing.

Save AU$201

The cheapest heating and cooling combo device in the Dyson family has also received a noticeable discount. The Hot+Cool Jet Focus is a small fan/heater without app support, but it does have a handy remote control. Given its size, it’ll operate better in small rooms, and as it’s not an air purifier, don’t expect it to make the air any less particle-y. That being said, it’s still a handy gadget for the home, and when you add the coupon BLKFR at the checkout, you can bring the price down to just AU$398 – a whopping 38% off.
