Dyson HushJet Purifier Compact HJ10 – Electrostatic & Carbon Filtration | MyDyson App | White/Silver | 491121-01

The Dyson HushJet Purifier Compact HJ10 491121-01 in White and Silver delivers powerful whole-room air purification from a compact design that can fit neatly into bedrooms, living spaces and home offices. Engineered to draw in airborne pollutants from across the room, it combines advanced filtration with Dyson's innovative HushJet air projection technology to circulate purified air effectively while keeping operating noise low.

Dyson's unique HushJet air projection system takes inspiration from jet-engine technology. A star-shaped nozzle smooths and directs the airflow while reducing turbulence, allowing the purifier to project clean air around the room without generating unnecessary noise. Despite its compact 470mm-high design, it delivers a maximum airflow rate of approximately 69.5 litres per second and can oscillate through 90 degrees to distribute purified air more widely.

A two-stage filtration system helps remove both airborne particles and unwanted household gases. The long-life 360° Electrostatic Filter captures 99.97% of particles as small as 0.3 microns, including common allergens, pollen, mould spores and fine dust. Dyson designs this filter to provide up to five years of service under specified usage conditions, significantly reducing how frequently it needs to be replaced.

Alongside the particle filter is a dedicated 360° Activated Carbon Gas + Odour Filter. This layer is designed to capture household gases such as nitrogen dioxide as well as common smells from cooking and pets. Dyson recommends replacing the carbon filter approximately every 12 months based on typical use, with filter-life alerts displayed directly on the machine and through the MyDyson app.

Integrated sensors continually monitor indoor air quality, allowing the HJ10 to react automatically as pollution levels change. Auto Mode adjusts purification performance according to the air quality in the room, while the built-in LCD display provides real-time information about pollutants and overall air quality. The display can show levels of fine PM2.5 particles and larger PM10 particles, giving you a clearer picture of what is present in the air around you.

Built-in Wi-Fi and Bluetooth connectivity allow the HushJet Compact to connect with the MyDyson app. From your smartphone you can remotely monitor air quality, adjust airflow, activate Auto or Sleep modes, set schedules and check filter life. Compatible voice control through Amazon Alexa, Google Assistant and Siri Shortcuts also provides convenient hands-free operation.

For bedrooms and quieter spaces, Sleep Mode operates at just 24dBA, reducing both airflow noise and display brightness for less disruption overnight. Maximum operating sound remains low at approximately 42dBA, while power consumption is below 19W at its highest airflow setting.

Compact, connected and designed specifically for air purification, the Dyson HushJet Purifier Compact HJ10 491121-01 is an excellent choice for households looking to reduce airborne allergens, fine particles, household gases and unwanted odours without adding a large appliance to the room.
