Dyson Purifier Cool PC1 review

The Purifier Cool PC1 is for buyers who want one machine that purifies all year and cools in summer. Dyson pairs a HEPA H13 filter, which it says captures 99.97% of particles as small as 0.3 microns, with an activated carbon layer for odors and VOCs, in a fully sealed filter system. Its Air Multiplier design projects over 76 gallons of air per second, which is what makes it useful as a fan. Sensors feed an auto mode that adjusts airflow to the measured air quality, and the MyDyson app shows captured pollutants, sets schedules and works with Alexa, Google Assistant and Siri. Dyson sold it for $399.99 when checked, down from $549.99, with free shipping, a 2-year limited warranty and free 30-day returns. What Dyson does not publish on the page is an AHAM CADR or a decibel range, so its cleaning speed cannot be compared with the Coway, Winix or Blueair figures. Pay for it as a fan with a good filter, not as the strongest purifier.
