Key Features of the Dyson HP4A
Advanced Air Purification
The HP4A features a 360° Glass HEPA and Activated Carbon Filter system that captures 99.97% of particles as small as 0.3 microns. The tris-impregnated carbon granules specifically target gases like formaldehyde, benzene, and nitrogen dioxide. Unlike standard traditional heaters, this system actively monitors and displays air quality in real-time.
Intelligent Climate Control
This 3-in-1 device offers:
- Precise heating with long-range projection
- Powerful cooling airflow for summer months
- Auto mode that maintains both air quality and temperature
Innovative Air Multiplier Technology
The patented Air Multiplier technology projects purified air throughout the entire room, circulating over 77 gallons of air per second. The 350° oscillation ensures even distribution, making it far more effective than standard space heaters.
Refurbished Quality Assurance
Dyson’s refurbished program ensures:
| Feature | Benefit |
|---|---|
| Expert servicing | Machines perform to original standards |
| Hygienic cleaning | All contact surfaces sanitized |

Smart Features & Convenience
Automated Operation
The HP4A automatically detects pollutants and adjusts settings accordingly. The LCD display provides real-time air quality reports, while the remote control (which stores magnetically on the unit) allows easy adjustments from anywhere in the room.
Low Maintenance Design
Filters typically last 12 months before needing replacement. The machine will notify you when filter changes are required, and replacement is a simple process. According to Dyson’s support site, the 360° Combi Glass HEPA + Carbon filter is specifically designed for this model.
