This Dyson air purifier redefines air purification. We set a new standard by going beyond conventional purifiers to solve problems that others have ignored.
Sensors
In real life, the only way to truly know how well an air purifier is working is to monitor the air quality. Dyson Pure CoolTM air purifiers have a unique algorithm that processes the input from three on-product sensors. Each sensor constantly monitors the air for particles, gases, temperature and humidity. When pollutants are detected, the air purifier (in auto mode) automatically reacts and adjusts the purifying settings to counteract the pollution and maintain the target air quality.
Reporting
The Dyson air purifier reports real time air quality data via the LCD screen on the air purifier and also via the Dyson Link app so users can access this remotely if needed. It reports on indoor air quality graph, PM 2.5, PM 10, NO2, VOCs, indoor temperature, indoor humidity, filter life and Wi-fi in the same order as mentioned.
Filtration
The 360° sealed filter is engineered to draw in air from all around the circumference of the air purifier. This allows for free positioning of the air purifier in the room. The filtration system is made up of two separate filters – a particulate HEPA filter and an activated carbon filter. 9m of borosilicate microfibers, pleated over 200 times, make up our high grade HEPA filter (H13-A). Within the carbon filter, the carbon granules now have a greater surface area, compared to earlier generations, to help capture more gases including Formaldehyde, Benzene and NO2.
By sealing the filters within the air purifier, air can only pass through the filters, not around them, so more particles can be captured in the first pass. This allows Dyson air purifiers to capture 99.95% of particles as small as 0.1 microns2.
Air MultiplierTM Technology
Dyson air purifiers use Air MultiplierTM technology to project purified air, while oscillating 350° for even coverage across the whole room1. The oscillation angle can also be customised via the Dyson Link app or onboard LCD screen to switch between personal cooling or around the whole room. Another benefit of this is that users can purify the whole room without having to reposition their air purifier.
Air MultiplierTM technology works by drawing in air through the filter via an energy-efficient, brushless motor. After passing through the two layers of the filter, the air is pressurised through the loop in the multiplier and exits as a high velocity jet, creating an area of low pressure that draws in air from behind the air purifier. As the jet of air leaves the front of the multiplier, more air is drawn in from the surroundings, amplifying the initial airflow even further. However, Dyson engineers have developed Air MultiplierTM technology further - by reducing the surface area that airflow covers and no longer turning the airflow through 180°, frictional losses are reduced and the system is more efficient than the previous generation.
Heating functionality
The Dyson Pure Hot+CoolTM air purifier can be used all year round - it is able to purify continuously and heat your room at the same time during winters.
Self-regulating ceramic plates are positioned at the front of the amp, to heat the air as it leaves the air purifier. As the plates heat up, they conduct less electricity to help ensure they don’t overheat. With thermostat control, once your target temperature is reached, the air purifier automatically stops heating, which saves energy. If the temperature starts to drop, it reactivates to maintain it.
