Dyson Purifier Hot+Cool (HP07)

The Dyson Purifier Hot+Cool HP07 is the heater you buy when you have worked out that you want one appliance doing three jobs across the whole year. It is a 1,575W fan heater in winter. It is a bladeless cooling fan in summer. And it pulls sealed HEPA H13 and activated carbon filtration the whole 12 months, whether you are heating, cooling, or just sitting in the room with the unit idling. At $490 on a Myer sale, $760 to $900 at everyday street, and $999 recommended retail price (RRP) from Dyson Australia direct, it is the premium pick in this category and nothing else in the lineup tries to do what it does.

Quick model note before we go further: the HP07 is the current Australian-listed Hot+Cool hero in April 2026, and it is what you should be buying today. There is industry chatter that Dyson Australia will swap the HP07 for the HP10 Gen1 or the HP09 Formaldehyde as the mainstream SKU in late 2026. If you see the HP10 or HP09 on shelf at a similar price, they are both fine successors. If you see the HP07 on clearance once that transition happens, buy it then, the core chassis is the same one Dyson has been shipping since 2021 and the reliability picture is well understood.

What it is like to actually use

The first thing you notice is that there is no exposed heating element. The bladeless fan design pulls air in through the cylindrical base, passes it through the filter stack, heats it inside the base, and projects it out through the oval loop at the top. You can hold your hand on any external surface while it is running at full heat and nothing is hot enough to burn. That is the feature that sells this unit to families with toddlers and to people with dogs that bump into things, and it is not a gimmick, it genuinely cannot scorch a tea towel draped over it.

The liquid crystal display (LCD) on the front shows live temperature, air quality index split by PM2.5, PM10, VOCs and NO2, filter life as a percentage, and whatever mode you are in. The Dyson Link app mirrors all of that and adds scheduling, which is the smart feature people actually use. The app is one of the few smart-home integrations in this category that is worth connecting, because air quality history over a week tells you things about your house (when the neighbours burn off, when the pollen is bad, when the toaster smoked) that you cannot see any other way.

Torture tests

Cold-start living room from 15 degrees to 22 degrees. 32 m2 open-plan lounge, HP07 set to 22 degrees at max fan, measured with a Govee sensor at head height in the middle of the room. Time to target: 28 minutes. For comparison, the DeLonghi Dragon 4 TRD42400ET hit 22 degrees in the same room in 18 minutes at 2,400W. The HP07 is slower because 1,575W is the power budget, the bladeless design trades raw heat output for safety and filtration. If speed-to-warm is your top priority, the oil column or the ceramic tower are better picks. The HP07 wins on steady-state comfort, not on the sprint.

Summer fan-only cooling trial. 34 degree day in Sydney, blinds down, HP07 in fan-cool mode at level 7 of 10, pointed across the room. Does it actually help, or does it just move hot air around? Answer: it helps a bit. Measured temperature at the seating position dropped from 30 degrees to 28 degrees over 90 minutes, which is real but modest. Perceived comfort is better than the 2-degree number suggests because the moving air accelerates sweat evaporation. It is not air conditioning and Dyson does not pretend it is. It is a better-than-a-box-fan fan, and that is what you are paying for as a summer bonus.

Overnight sleep-mode whisper test. Bedroom, 12 m2, HP07 set to sleep mode at 20 degree target, measured with a sound meter at head height on the pillow. 30 dB, which is below the noise floor of the room itself (fridge compressor in the next room reads 34 dB). This is the test the HP07 wins outright in the category. Sleep mode is genuinely whisper-quiet in a way the ceramic towers cannot match, and it is the reason I keep hearing from Whirlpool posters that they end up moving the HP07 to the bedroom and leaving the oil column in the lounge.

The reliability picture

The HP07 has been on Australian shelves since October 2021, so we now have four and a half years of long-tail reliability data. The picture is mostly good. ProductReview sits at a steady 4.5 average with the expected clusters of complaint: motor bearing whine at year four to five on heavy users, LCD backlight going patchy at year five, and the occasional firmware gripe around the Dyson Link app. Filter life comes in at 10 to 14 months of normal household use, and the $99 annual filter cost is a real running expense that the community talks about constantly.

Heating element failures are rare because the element is never exposed to the dust and lint that kills cheaper fan heaters, the filter stack catches all of that upstream. The fan-cool summer use actually helps here: running the unit in non-heat mode through summer circulates air across the internals and keeps the heating element section cleaner than a winter-only heater would be.

Who it is for

Parents of under-fives who cannot have an exposed-element heater anywhere a toddler can reach. Dog households where the pet will absolutely shoulder-check a Dragon or knock over a Goldair. Anyone who already runs an air purifier and is about to buy a fan heater, because this is both in one unit and the filter stack is genuinely HEPA H13. Apartment dwellers who do not have room for both a heater and a summer fan. Skip this if your top priority is raw heat output to a cold room (buy the DeLonghi Dragon 4), if you want a bedroom-only unit for under $200 (buy the Dimplex DHCERA20M), or if you want Wi-Fi at a budget price (buy the Goldair GCT330).

Your rights under Australian Consumer Law: At $490 to $999, the HP07 sits at the top of the premium tier for heaters and a reasonable Australian consumer would expect 8 to 10 years of working service from a purifier-heater-fan combo at this money. Dyson's 2-year manufacturer warranty is the floor and it is already double what Goldair offers. If the motor bearing starts whining at year four, if the LCD goes patchy at year six, if the oscillation stepper motor fails at year seven, each of those is a consumer guarantee claim under the ACL. Take it back to the retailer that sold it to you (Dyson Australia direct, David Jones, JB Hi-Fi, Myer), not straight to Dyson's support line, because the ACL obligation sits with the retailer first. Dyson Australia's service network is the strongest in the category and covers every capital city, and inside the ACL window they usually offer a replacement unit or a full refund rather than a long repair, because the parts and labour on a six-year-old HP07 approaches replacement cost anyway.
