Dyson HP12 Air Purifier Hot+Cool & Fan (Allergy Friendly, White Gold) | HEPA + Activated Carbon Filter | Removes 99.95% Pollutants | Auto, Night & Diffused Mode | Remote Control | 2-Year Warranty | Premium Design for All Seasons

The Dyson Hot+Cool HP12 is a premium all-in-one air treatment device designed to purify the air, cool you during warmer weather, and provide targeted heating in cooler months. It is certified for allergy- and asthma-friendly use and is engineered for year-round comfort and air quality. Featuring Dyson’s patented Air Multiplier™ technology, it draws in room air, forces it through a sealed HEPA + activated carbon filtration system that captures 99.95% of ultrafine pollutants down to 0.1 microns, and projects purified air across the whole room.

It senses airborne particles (PM2.5, PM10), volatile organic compounds (VOCs), and nitrogen dioxide (NO₂) in real-time and displays air quality data on its LCD screen.

The HP12 further features selectable modes: heating mode, cooling/fan mode, auto mode (where the purifier adjusts to maintain air quality/temperature), night mode for quieter operation and dimmed display, and diffused mode (where air is projected less directly, useful when you want purification without feeling a direct airflow).

The design is sleek: a bladeless loop amplifier in a nickel & gold finish, with remote control and app connectivity (the MyDyson or Dyson Link app) so you can monitor and control the device from your smartphone. It has 350° oscillation to ensure the clean air reaches all corners of your room and uses thermostat control for heating (it stops heating once the target temp is reached to save energy) and switches back on if the temperature drops.

In short, this unit is tailored to users who want a high-end, multi-functional device: air purification + heating + cooling, with strong filtration, smart sensing/reporting, and design presence. It’s especially suited for urban homes with air-quality concerns (e.g., allergies, pollution, indoor smoke/odors) and varying seasonal temperature needs.
