It’s that time of year again when we’re not always sure whether to leave the house dressed for summer or winter. And while this transitional phase can be a nightmare for wardrobe choices, it means that summer is right around the corner, so it’s time to start thinking about how you’ll stay cool at home and beat the heat. And let’s not forget that this is an El Niño year, so spring and summer will be drier than usual and potentially hotter, with a higher probability of bushfires. So, along with the heat, we’ll also need to contend with the smoke and ash in the air, which could cause respiratory disorders. Long story short, it’s time to invest in a good purifying fan to see us through the coming months here in Australia.Fortunately, Amazon understands this and has slashed up to AU$300 on some of Dyson’s powerful, bladeless fans to help keep you and the family cool when the temperature rises. I’ve highlighted three of my favourites below, all of which will not just purify the air you breathe at home and keep you cool, but will keep you toasty in the colder months. That’s good value for a gadget you can use year-round. If Dyson doesn’t tickle your fancy, I’ve also listed some highly recommended alternatives from the likes of Vornado and Shark. Pure Hot+Cool HP00 Purifier: was $499 now $399.20The HP00 is a three-in-one model, covering cooling, purifying and heating, making it a truly versatile unit and a good price — well, for a Dyson. Its 360º HEPA filtration system captures 99.95% of particles as small as 0.1 microns, while 70º oscillation helps circulate purified air around your room.View DealThe Pure Hot+Cool Link offers the same three-in-one functionality as the HP00, but has the added benefit of smartphone connectivity, letting you monitor air quality and control the machine remotely from your phone. View DealPurifier Hot+Cool HP2 De-NOx: was $1199 now $899You also get three-in-one functionality with this Dyson fan, but it combines HEPA H13 filtration with advanced gas removal, including the continuous destruction of formaldehyde that can be released by nearly everything we own in our homes today, including new furniture.
