Dyson Pure Cool Air Purifier (Advanced Technology), Wi-fi & Bluetooth Enabled, Model DP04 (Iron/Blue) Dyson Pure Cool (Advanced Technology) air purifiers have a unique algorithm that processes the input from three on-board sensors – diagnosing and reporting air quality metrics in real time. So you can see your air quality right now, and maintain it at the right level. Sensors - Humidity and temperature sensor constantly monitors the relative humidity and temperature in the room. Particles sensor uses laser measurement for constant particulate concentration analysis. Gas sensor detects volatile organic compounds and NO2. Filters - The sealed filtration system has two advanced filters to capture 99.95% of particle pollution as small as 0.1 microns. The H-13 Glass HEPA Filter is pleated over 200 times and densely packed with borosilicate microfibres which preventing dirty air from leaking back into the room. Improved activated carbon filter with Tris impregnation; New carbon filter with over three times more activated carbon than our previous generation – to capture more gases including formaldehyde, benzene and NO2. And in-built monitoring lets you know when the filters need replacing. Projection - Air Multiplier technology Projects over 360 litres of air per second, generating smooth yet powerful airflow. This combines with 350° oscillation to project and circulate purified air throughout the A1entire room. Small footprint, 360 degrees air-intake allows for easy placement ANYWHERE in the room. Dyson purifiers have a lower face velocity unlike some other conventional purifiers. This, along with the high-efficiency VACUUM SEALED 360 degrees Glass HEPA FIlter ensures that harmful ultra-fine pollutants are NOT released back into the room & stay captured in the filter media. Intelligent control with in-depth reporting The Dyson Pure Cool air purifier connects to the Dyson Link app to control and monitor your home air quality from anywhere. Like the LCD screen on the machine, it provides detailed information on the pollutants that have been captured. However, it also provides more control of your machine – such as customising the oscillation angle and setting purifying schedules - along with giving you indoor and outdoor air quality records. So you can see precisely how well it’s performing. Made for real homes, and not just labs Some manufacturers of conventional air purifiers gauge their performance using a laboratory test method called ‘Clean Air Delivery Rate’. It is conducted in a compact chamber (11.8m2), with an added fan to circulate the air – and only one sensor to measure air quality. Dyson air purifiers go further. Dyson air purifiers are designed to work in real homes. So we’ve developed the POLAR test, based on a large living room size (27m2), with no added fan. Nine different sensors collect air quality data throughout the room, so we can make sure it purifies every corner. It’s why we want to make it an industry standard test. We tested conventional purifiers in our lab which is designed to replicate real homes, with no mixing fan and multiple sensors. We found that some machines are only able to purify the air around the machine – creating a ‘clean air bubble’ – while areas further away remain polluted. Dyson air purifiers project purified air around the whole room. Dyson Air Multiplier technology projects purified air to every corner of the room. So you know that wherever you are in the room, the air around you is purified. Other features include easy scheduling, 10 air-speed settings, auto mode, night-time mode, sleep timer, and an easy-to-clean aperture with no fast-spinning blades so it’s safe for little fingers or paws. Comes with a remote control that is magentized for easy docking on top of the machine when required. The AHAM AC1-2015 standard sets out how air cleaner manufacturers can define their performance in a specified test chamber. This means their performance is based on cleaning efficiency rates only. We design our purifying fans to go beyond test chamber conditions and focus on real home conditions – this is more than just having an efficient filter. When Dyson engineers set out to design a purifying fan, their research concluded that to clean an entire family room properly, you also need to sense pollution events automatically; capture ultrafine pollutants; and project cleaner air around the room using Air Multiplier technology. Only the Dyson purifying fan is designed and tested to do all of this. *Tested for filtration efficiency (EN1822) at 0.1 microns and "excellent’’ whole room coverage (TM-003711 and DTM801) in a 27m2 room. *Tested to GB/T18801 (formaldehyde, benzene). Gaseous capture rates vary. Tested to EN1822 - airborne particles as small as 0.1 microns.
