Level with the Dyson Big+Quiet Formaldehyde

About the Dyson Purifier Hot+Cool HP1
The HP1 is a bladeless tower, 756 mm tall, 205 mm wide and 131 mm deep, and weighs about 5.3 kg. It has 10 fan speeds. The filter is HEPA 13, with an activated carbon layer for odours and gases. Dyson says to replace the filter every 12 months, and the MyDyson app tracks its life.
In summer it works as a fan. In winter it gives out warm air. Dyson says it suits well-insulated rooms or occasional heating, and a Mumsnet reviewer would not use it in place of central heating. It oscillates up to 350 degrees, which helps in an open-plan room. Leave at least six inches of clearance from walls, and keep it away from open windows, doors and radiators.
A magnetic remote controls temperature, speed, oscillation and modes. The MyDyson app shows air quality, room temperature and filter life, and lets you schedule it. A night mode uses the quietest setting and dims the display. The filter comes fitted, and the unit also works with Alexa, Google Assistant and Siri. Quiet mode runs at around 46 dB, and the top speed reaches around 63 dB.
What owners report about the Dyson Purifier Hot+Cool HP1
We found little written UK owner feedback for this exact model that we could read in full. Retailer pages show an overall rating but not the comments, and the Mumsnet page is mostly a single reviewer's write-up. The one reader comment there comes from someone who bought a second unit.
The reviewer on that page liked the fan strength at higher speeds, the quick warm-up and its work on cooking and pet smells. They found the lowest speeds a soft whoosh and the top speed loud enough to turn the TV up. They also disliked the small display, the short remote range, the lack of a child lock and the cost of replacement filters. That is one reviewer's view, not a pattern across owners.
Who the Dyson Purifier Hot+Cool HP1 suits
The HP1 suits someone who wants a purifier that also cools and heats, in a bedroom or living room that holds heat well. It is light enough to carry between rooms, and the app and schedules will suit people who like to automate.
Look elsewhere if you only want clean air. A plain purifier such as the Levoit Core 300S has a similar type of filter and no heater. For a small room, the Levoit Core Mini is the smaller option. For a big open-plan space, the Dyson Big+Quiet Formaldehyde is built for it. It is also a poor main heater for a draughty room.
Questions about the Dyson Purifier Hot+Cool HP1
How do you use the Dyson Purifier Hot+Cool HP1?
Stand it with clearance from walls and away from open windows, doors and radiators. Then control it with the magnetic remote (temperature, speed, oscillation, modes) or the MyDyson app, which also handles scheduling.
Does the Dyson Purifier Hot+Cool HP1 use a lot of electricity?
We found no running-cost figure from Dyson or the retailers we read. Dyson says the heater suits well-insulated rooms or occasional heating, not as a replacement for central heating.
Does the Dyson Purifier Hot+Cool HP1 cool as well as heat?
Yes. It works as a fan in summer, and a John Lewis editor says it cools quickly and quietly. It does not chill the air like an air conditioner.

Every 12 months, according to Dyson. The MyDyson app tracks the filter's life.
What guarantee does the Dyson Purifier Hot+Cool HP1 have?

Other air purifier picks
The other badge winners in our air purifiers ranking.
Every score here comes from our ranking model; no editor sets the order. Too few review sites cover air purifiers for their verdicts to lead, so this ranking is led by owners. It ranks products by how happy owners are, holding back any product few owners have rated until more agree. How many rated it and how new it is only settle close calls, and value for money earns its own badge rather than a higher place. We compared 16 models for this guide before settling on these ten.
Brands can't pay to be included or to move up. We last checked these picks in October 2026.
