Dyson Purifier Hot+Cool Gen1 Review

The Dyson Purifier Hot+Cool Gen1 is a tri-purpose device that purifies, heats, and cools a room. The HEPA H13 filter captures 99.97% of particles as small as 0.3 microns, including allergens, pollen, and bacteria. The activated carbon layer removes odours and VOCs. The LCD display shows real-time PM2.5, PM10, VOC, and NO2 levels.

In winter, the thermostat-controlled heating (up to 99°F) efficiently warms a medium-sized room. In summer, the bladeless fan provides a smooth, powerful airflow. The 350° oscillation distributes air evenly, and the remote is magnetically stored on top.

The $570 price tag is steep, but it replaces three separate devices and the filter lasts about a year under normal use. For studio apartments or rooms where space is at a premium, the Dyson Hot+Cool is a compelling all-in-one solution.
