Which one to pick

Take the Blueair Blue Pure 211+

Leads on Performance, Value and Quietness.

  • An open-plan living space rather than a bedroom-sized box
  • You want one control and no app
  • The washable fabric sleeve catching pet hair appeals to you

Take the Dyson Purifier Cool TP07

Leads on Durability and Ease of use.

  • A small apartment where one machine has to be the fan and the purifier both
  • Winter, where diffused mode cleans the room without blowing cold air across it
  • You want a live readout and an auto mode that actually acts on it

What each one gets wrong

Blueair Blue Pure 211+

  • Seeing a particulate number is part of trusting the machine
  • Carbon filtration for cooking smells is a priority

Dyson Purifier Cool TP07

  • Clean air delivered for the money is the axis you are shopping on
  • Yearly proprietary cartridges from a single supplier are a problem
  • A tall narrow tower near a dog or a toddler is a thing waiting to be knocked over
