Product Overview

The Dyson Purifier Hot+Cool HP2 De-NOx White/Gold 546294-0 heats in winter(1), cools in summer(2) and purifies all year. Fully sealed three stage HEPA H13 grade filtration captures 99.95% of ultra-fine particles(3) that removes odours and gases(4), continuously destroying formaldehyde(5) and capturing NO2.

Advanced air purification automatically captures 50% more nitrogen dioxide(6) with the K-Carbon filter impregnated with potassium carbonate (K2CO3) and can adsorb 50% more.

In Auto mode the purifier reacts automatically to remove pollutants, only using energy when needed. In Night mode
turbulence and noise is reduced, perfect for a good night’s sleep or peaceful working environment.

Control and monitor air quality from anywhere using the MyDyson app, or hands-free with compatible voice services(7). Changing the HEPA+K-Carbon filter is quick and easy as the LCD screen and MyDyson app can notify you when it needs to be replaced.

    Excellent all-in-one purifier

    I’m very happy with this Dyson Purifier Hot + Cool HP2 De-Nox. It works brilliantly as a purifier, heater and fan all in one unit. The air quality in my room noticeably improved within a short time, and it’s especially great for reducing odours and dust. The design looks premium, it’s easy to use, and the app control is very convenient. Heating is quick in winter and the cooling airflow is smooth and quiet. Overall, a high-quality product with excellent performance.
