Dyson Purifier Hot+Cool HP07: Year-Round Air Quality Excellence

Three Appliances in One Premium Package

Dyson's HP07 consolidates three essential home appliances into one sophisticated unit: a professional-grade air purifier, an efficient space heater, and a powerful cooling fan. This integration isn't just about saving space – it's about delivering superior performance in each function while maintaining Dyson's signature aesthetic and engineering excellence.

For homes seeking clean air year-round along with supplemental heating and cooling, the HP07 eliminates the need for separate appliances, reduces clutter, and provides seamless seasonal transitions through a single, beautifully-designed unit.

Advanced HEPA H13 Filtration System

At the core of the HP07's purification capability is a sophisticated three-stage filtration system that captures an astonishing range of pollutants and allergens.

Sealed HEPA H13 Filter

The HEPA H13 filter captures 99.97% of particles as small as 0.3 microns – including pollen, bacteria, pet dander, mold spores, and fine dust. The H13 rating exceeds the minimum HEPA standard (H10), providing medical-grade filtration that significantly improves indoor air quality.

Critically, the entire purifier is sealed to HEPA H13 standard, not just the filter. Many air purifiers use HEPA filters but allow air to bypass through unsealed gaps, reducing real-world effectiveness. Dyson's whole-machine seal ensures that all air passing through the device is genuinely filtered to H13 standards.

Activated Carbon Filter

The activated carbon layer captures gases, odors, and volatile organic compounds (VOCs) including formaldehyde, benzene, and nitrogen dioxide. This chemical filtration complements the particle capture, addressing both particulate and gaseous pollutants for comprehensive air cleaning.

The carbon filter is particularly effective against common household odors from cooking, pets, smoke, and cleaning products, along with outdoor pollution that infiltrates indoor spaces.

360-Degree Glass HEPA Filter

Unlike flat filter designs, the HP07 uses a cylindrical 360-degree filter that maximizes surface area for increased capacity and longer filter life. Air is drawn through the entire filter circumference, improving filtration efficiency and ensuring even filter utilization.

Real-Time Air Quality Monitoring

The HP07 doesn't just clean air – it continuously analyzes it, providing detailed real-time data about your indoor air quality through sophisticated sensing technology.

Advanced Sensor Suite

Three integrated sensors continuously monitor air quality: a particle sensor detects PM2.5 and PM10 particulates, a VOC sensor identifies gaseous pollutants, and a nitrogen dioxide sensor tracks this specific harmful gas. Temperature and humidity sensors provide additional environmental data.

This comprehensive monitoring enables the HP07 to make intelligent decisions about purification intensity while informing you about your air quality through the LCD display and Dyson Link app.

LCD Display

The front-mounted LCD screen displays real-time air quality data, showing particulate levels, VOC concentrations, nitrogen dioxide levels, temperature, and humidity. The color-coded display makes understanding air quality instant – green for good, yellow for moderate, red for poor.

This transparency transforms air purification from a blind process to an informed one. You see exactly how polluted your air is and watch in real-time as the HP07 cleans it, providing both confidence and satisfaction in the purification process.

Intelligent Auto Mode

The HP07's Auto mode leverages the sensor data to optimize purification automatically, adjusting fan speed based on detected pollution levels.

Responsive Automation

When Auto mode detects increased pollution – whether from cooking, opening windows, or other sources – it automatically increases fan speed to accelerate purification. As air quality improves, the unit reduces power to conserve energy while maintaining clean air.

This intelligent operation means you can largely set-and-forget the purifier, trusting it to maintain optimal air quality without manual adjustment. The responsiveness is impressive, often increasing fan speed within seconds of pollution sources appearing.

Night Mode

Night mode maintains quiet purification for bedroom use, operating at reduced speed with dimmed display while continuing to monitor and respond to air quality changes. The whisper-quiet operation ensures sleep isn't disturbed while maintaining clean breathing air throughout the night.

Air Multiplier Technology

Dyson's patented Air Multiplier technology, featured in the iconic bladeless design, doesn't just look futuristic – it delivers superior air projection and whole-room circulation.

Bladeless Design Benefits

The bladeless design eliminates the safety concerns and cleaning difficulties of traditional bladed fans while enabling smooth, uninterrupted airflow. The aperture amplifies airflow, drawing in surrounding air and projecting a high-velocity stream that circulates throughout the room.

This circulation is critical for effective purification. Purifiers that don't circulate air well create clean pockets while leaving distant areas polluted. The HP07's powerful projection ensures room-wide purification, moving clean air to every corner.

350-Degree Oscillation

The unit oscillates up to 350 degrees, projecting purified air broadly throughout the space. You can adjust oscillation angle through the app or remote, targeting specific areas or achieving maximum room coverage as needed.

Focused vs. Diffused Mode

Focused mode projects a concentrated stream of air for direct personal cooling or heating. Diffused mode distributes air more broadly for whole-room circulation without direct breeze – ideal for purification-only operation or gentle heating without focused hot air.

Heating Functionality

Beyond air purification, the HP07 serves as an efficient supplemental heater for quick warming or maintaining comfortable temperatures in personal spaces.

Fast Heat Technology

The ceramic heating element heats air rapidly and projects warm air throughout the room via Air Multiplier technology. The unit heats noticeably faster than traditional space heaters, bringing small-to-medium rooms to comfortable temperatures quickly.

Thermostat Control

Set your desired temperature (ranging from 32°F to 99°F), and the HP07 automatically maintains it, cycling heating on and off as needed. This thermostatic control prevents overheating while ensuring consistent comfort.

The heating capability is suitable for supplemental warmth in offices, bedrooms, or other personal spaces. It won't replace central heating for whole-home warming but excels for targeted comfort in the spaces you occupy.

Energy Efficiency

As a supplemental heater, the HP07 can reduce overall heating costs by allowing you to lower whole-home thermostat settings while maintaining comfort in occupied rooms. The precise thermostat control prevents energy waste from overheating.

Cooling Performance

In warm months, the HP07 functions as a powerful fan, providing cooling airflow without the air quality compromise of open windows.

High-Velocity Airflow

The unit generates powerful, smooth airflow that provides effective personal cooling. Ten airflow speed settings allow precise control from gentle breeze to strong cooling wind.

Purified Cooling

Unlike traditional fans that simply circulate existing air (including pollutants), the HP07 purifies before cooling. This combination is particularly valuable during high-pollen seasons or poor outdoor air quality when opening windows would compromise indoor air despite providing cooling.

Timer and Scheduling

Set sleep timers or schedules through the app, automatically turning cooling on before you arrive home or off after you fall asleep. This automation enhances convenience and energy efficiency.

Smart Home Integration

The Dyson Link app and voice control integration bring sophisticated automation and remote control capabilities.

Dyson Link App

The comprehensive mobile app provides complete control over all HP07 functions remotely. Monitor air quality from anywhere, adjust settings, create schedules, and review historical air quality data that helps identify pollution patterns.

The app's air quality history is particularly valuable, revealing temporal patterns like cooking impact on air quality or outdoor pollution infiltration, helping you understand and address air quality issues systematically.

Voice Control

Amazon Alexa and Google Assistant integration enables voice control for basic functions like power, mode changes, and temperature adjustment. The hands-free control is convenient when entering rooms with arms full or when relaxing without phone access.
