What does it do?
Aside from removing formaldehyde, it’ll also filter particles (as small as 0.01 microns, including 99.95 per cent of bacteria, pollen, and mould spores). It’s worth noting that the whole machine is rated to Hepa 13 standards rather than just the filter, meaning it’s sealed from inlet to outlet, effectively grabbing – and hanging onto – all the particles you don’t want in the air.
Additionally, it is designed to be a heater and a fan, heating or cooling a room really quickly (we noticed the ambient temperature rise and fall in minutes after it was switched on, and it’s definitely more effective than other room heaters we’ve tried).
How easy is it to use?
Once you’ve unwrapped the filter and plugged it in, you can either let the machine do its thing and keep it on automatic, or control it via the app or the remote control provided (that attaches to the top of the purifier via a magnet). The app will track all the info in a series of graphs, and you can compare current to previous air quality in quite some depth.

The machine itself also has a small monitor that you can look at for information, and where you can schedule the heater (the in-built thermostat also means you can set it to only heat when the indoor temperature falls below a certain level, if you want to). Once going, expect it to deliver 520sq m of clean air an hour.
What about the design?
Dyson has excelled here. The body looks like punched gold, while the white oblong atop the filtering cylinder is futuristic and pleasing so we didn’t want to hide it away in the corner of a room.
It’s also quiet – yes, you can hear the fan or heater when it’s on full blast, but it fades into the background when running on a normal everyday setting, and being able to switch the speed up on the fan function was handy when trying to absorb cooking smells/spritzes of deodorant/smells of adhesive after using during building works.
The head turns so you can hit different parts of the room as needed, and you can tilt it, so there’s a lot of customisation available in the design.
