Dyson's New Purifying Fan & Heater Adds a Screen, Better Filtration and Heating

Dyson has developed a new version of its Pure Hot+Cool purifier, which adds new sensors, an LCD screen, better filtration, and heating capabilities.

The new device can deliver fast and even room heating in winter, powerful personal cooling in summer, and efficient purification through all seasons. It automatically detects airborne particles and gases, and simultaneously reports this information via a new LCD on the machine and the Dyson Link app in real time.

"We insist on developing technology that works properly, without compromise on any functions," says Sam Bernard, Global Category Director, Environmental Control. "Our latest machine goes beyond standard tests. It heats and cools you quickly and effectively - while always purifying the whole room. As we seal up our homes for the winter and trap pollutants in, a heater that can help rid the air of harmful particulates becomes all the more important."

To simultaneously purify and heat a whole room properly, the Dyson Pure Hot+Cool Air Purifier, Heater & Fan automatically senses pollution, capturing ultrafine pollutants, and projecting purified and heated air using Air Multiplier technology. It is the only HEPA Air Purifier, Heater & Fan designed and tested to do this, says Dyson. The standard purification and heating performance tests are AHAMAC1-2015 and IEC 60675, respectively. Dyson goes beyond these, by testing filtration efficiency, air projection (DTM801), purification coverage in a 2860 ft3 room with multiple sensors (TM-003711) and heating performance in a 1236 ft3 room with multiple sensors (DTM961).

As modern homes are becoming better sealed to comply with energy efficiency requirements, those pollutants can be trapped inside and air circulation can be compromised, especially in winter, Dyson notes.

The new device targets sources of pollution and works to automatically capture them, and project cleaner air around the room. The screen shows the particles and gases the Dyson Pure Hot+Cool purifying fan + heater is automatically sensing in real time using a unique Dyson algorithm. Lasers measure and identify fine particles. Another sensor detects the amount of VOCs, such as benzene and formaldehyde, and NO2 (Nitrogen Dioxide) present. And yet another measures relative humidity and temperature.

Dyson engineers have incorporated 60% more HEPA media into a taller and deeper HEPA filter, and they've introduced three times more activated carbon than the original Dyson Pure Hot+Cool Link, meaning the new filter can absorb more gases, odors, domestic fumes and VOCs.

The machine's sealed HEPA filter captures 99.97% of particle pollution as small as 0.3 microns, including allergens, bacteria, pollen, and mold spores. Activated carbon filters, which have been coated with Tris (Trishydroxymethylaminomethane) to increase their absorption efficiency, remove gases including NO2, formaldehyde, and benzene.

Air Multiplier technology and 350° oscillation project air around the whole room. Dyson engineers tested the machine using a moveable 3D rig fitted with velocity probes to measure air force at different levels within the room. Using this data, the company made numerous iterations of its air apertures to make sure that the machine circulates the air effectively for whole and even room purification.

To deliver better heating performance, Dyson engineers optimized the air amplifier geometry to balance room mixing and tested 80 different heating configurations of the heating element to find the most suitable combination. With thermostat heat control, the machine automatically keeps your room at the target temperature. The heating function will switch to stand-by mode once the target is reached and will switch back on once it senses a drop in the temperature.

To maintain airflow projection out the front of the machine, a baffle in the amplifier stays in place to deliver a powerful, frontward stream of purified air. This can cool you down in the summer and heat you in the winter, while simultaneously purifying the room. In backward airflow mode, the baffle moves to block the front aperture, diverting air through the rear of the annular loop at a 45⁰ angle. Because the aperture is wider, this creates a more diffused airflow, uses less energy, generates less noise and purification effectiveness is maintained.

Available for iOS and Android, the Dyson Link app enables you to track indoor and outdoor pollution, temperature, and humidity levels. You can also use it to see how many hours of filter life you have left.

The new machines come with full Over the Air Update Capability (OTA), meaning Dyson product owners can continue to get the most advanced Dyson software even after purchasing the machine.

The new Dyson Pure Hot+Cool purifying heater + fans are available in a White/Silver, Black/Nickel, and Iron/Blue, and come with a magnetized remote control can be neatly stored on top of the machine and used to control the functioning of the product. They sell in Canada for $750.
