Dyson Purifier Humidify+Cool Formaldehyde PH04 (White/Gold)

Breaks Down Formaldehyde Instead of Just Trapping It

The PH04 pairs a HEPA H13 filter capturing 99.97% of particles down to 0.3 microns with a solid-state formaldehyde sensor and a dedicated catalytic filter that continuously breaks formaldehyde down into harmless substances rather than storing it up. A separate filter stage handles gases and odors, so the machine addresses both particulate pollution and the invisible chemical kind in one pass.

A one-gallon tank delivers up to 36 hours of hygienic humidification per fill, and Air Multiplier™ technology projects the purified, humidified air across the room instead of pooling it near the base. Ten speed settings and versatile airflow modes — including cooling, backward airflow, and breeze — let you dial in exactly how the air moves through the space, with 90° oscillation for wider coverage.

Integrated sensors continuously monitor air quality and adjust settings automatically in response, while app and voice control, a night mode, and a deep clean cycle keep day-to-day operation simple.
