Questions people ask
How much was the Dyson HP2 De-NOx cut last Black Friday?
About 26%, reported on 28 November 2025.
What does De-NOx mean on the Dyson HP2?
Its carbon filter is treated to catch nitrogen dioxide, a gas from traffic and gas cookers, on top of the usual dust and odours.
Is the Dyson HP2 worth it over a plain purifier?
Only if you'll use the heater and fan. One long-term review liked having one machine for a small room, but called it expensive.
