Dyson's purifiers are beautifully designed and genuinely clever — but you're paying for the design, the app and the fan-heater tricks, not for clean-air delivery. On CADR per pound, a high-airflow MERV-13 kit clears a room faster for a fraction of the price.

You give up the sleek tower and the heating/cooling gimmicks. You don't give up clean air — you get more of it, quietly, with cheaper filters and no lock-in. For a London home where the job is clearing traffic PM2.5 and pollen, that trade is easy.
Frequently asked questions
Is a cheaper purifier really better than a Dyson?
On clean-air delivery per pound, yes — a high-airflow MERV-13 kit moves more filtered air for far less. You lose the styling and heater features, not the air cleaning.
Are the filters cheaper?
Much cheaper. MERV-13 media is a standard replaceable part (3M Filtrete, from ~£58 a pair) rather than a proprietary Dyson cartridge.
