Dyson Purifier Hot+Cool Gen1 HP10 (Silver)

How effective is the HEPA H13 filter at removing particles?

The HEPA H13 filter captures 99.95% of particles as small as 0.1 microns, which includes most allergens, bacteria, dust mites and ultrafine particles. This grade exceeds standard HEPA requirements and removes particles 10 times smaller than typical HEPA filters. The fully sealed system ensures captured pollutants cannot escape back into your room.

Can this unit effectively heat and cool large rooms?

The HP10 covers up to 27m² for air purification and effectively heats rooms up to 35m³. The Air Multiplier technology projects airflow across the entire room rather than just the immediate area. For cooling, it provides personal comfort rather than whole-room air conditioning, making it ideal for bedrooms, offices, or living spaces up to medium size.

How loud is the unit during operation?

Maximum noise level reaches 59.8dB, similar to normal conversation volume. At lower speeds (1-9), the unit operates very quietly and is barely audible. Night mode is specifically designed for bedroom use with minimal noise output. The bladeless design eliminates the whooshing sounds of traditional fans whilst maintaining effective airflow.

What maintenance does the filter system require?

The combined HEPA and carbon filter typically lasts 12 months with average use. The LCD display shows filter life remaining and alerts you when replacement is needed. Filter changes take minutes without tools - simply remove the old filter and click in the new one. Replacement filters cost approximately £40 and maintain the unit's effectiveness.

Does this model connect to WiFi or smartphone apps?

No, the HP10 does not have WiFi connectivity or app control. The Dyson app is only used for product registration and accessing user manuals. All controls are via the magnetic remote control or buttons on the unit itself. Air quality readings are displayed in real-time on the LCD screen but cannot be tracked historically.

How does the auto mode work?

Three sensors continuously monitor PM2.5, PM10, volatile organic compounds and nitrogen dioxide levels. When pollutants are detected, auto mode increases fan speed automatically to capture them quickly. Once air quality improves, the unit reduces power to save energy. This maintains optimal air quality without manual adjustment throughout the day.

Is the unit safe to use around children and pets?

Yes, the bladeless design eliminates injury risks from exposed fan blades. The weighted base (5.7kg total weight) provides excellent stability and reduces tipping risks. Auto shut-off features prevent overheating and the unit meets safety standards for home use. The smooth surfaces and rounded edges make it safe for households with children and pets.

What oscillation angles are available?

The unit offers four oscillation settings: 45°, 90°, 180° and 350° rotation. This allows you to direct airflow precisely where needed or distribute it across the entire room. The unit also tilts 15° forward and backward for optimal air projection. Oscillation can be turned off to focus airflow in one direction.
