Fan modeThe Dyson Pure Hot+Cool air purifier features a unique new diffused airflow mode along with fan mode.Dyson engineers tested the machine using a moveable 3D rig fitted with velocity probes to measure air force at different levels within the room.Engineered for real homesIndustry standard purifier tests are conducted in small chambers with a ceiling fan and only 1 sensor, which is not representative of actual living room environments. It heats and cools you quickly and effectively – while always purifying the whole room.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.Air pollution is a huge problem in India with 14 out of 15 most polluted cities in the world in terms of PM 2.Dyson Link app: Available for iOS and Android, the Dyson Link app enables you to track indoor and outdoor pollution, temperature and humidity levels.Dyson launched an air purifier plus heater uniquely engineered for year round use, the new Dyson Pure Hot+Cool air purifier. In the kitchen and living room, cleaning products emit VOCs, dander from household pets, gas hobs and other cooking processes release particulate matter, fumes and odours. Analysing the data across all nine sensors lets Dyson engineers ensure the Dyson Pure Hot+Cool air purifier delivers a uniform cleaning performance throughout the whole room. You can also use it to control your machine and see how many hours of filter life you have left. Potential sources include particulate matter from city pollution, VOCs (Volatile Organic Compounds) from hair spray and perfume, formaldehyde from foam furniture, dust and allergens from carpets and benzene from scented candles. Eight sensors in the corners of the room and one sensor in the centre collect air quality data every 5 seconds, detecting particles of indoor air pollution that are 300 times narrower than a human hair.Lasers measure and identify fine particles. And the third sensor measures relative humidity and temperature.Projecting: By expanding the degree of oscillation to 350⁰ degrees and using Air Multiplier Technology, the machine can project up to over 290 litres of purified air per second to every corner of the room.5 are in India, as per a recent WHO report.Sensing: A new LCD shows the particles and gases the Dyson Pure Hot+Cool air purifier is automatically sensing in real time using a unique Dyson algorithm. 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. 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.With thermostat heat control, the machine automatically keeps your room at the target temperature.Moreover, air pollution in India is a year-round problem, with pollution hitting its peak in winter months especially in northern part of the country. Another sensor detects the amount of VOCs (Volatile Organic Compounds), such as benzene and formaldehyde, and NO2 (Nitrogen Dioxide) present.Capturing: Dyson engineers have incorporated 60% more HEPA media into a taller and deeper HEPA filter, and they’ve introduced three times more activated carbon, which can absorb gases, odours, domestic fumes and VOCs.95% of particle pollution as small as 0. It delivers fast and even room heating in winter, powerful cooling in summer and efficient purification through all seasons.Sam Bernard, Global Category Director, Environmental Control, says, "A good air purifier should sense, capture, project, heat and cool you.  

This variation in temperatures across the year and high pollution levels through the year makes Dyson Pure Hot+Cool air purifier an all year round technology that is suitable for all seasons. As awareness rises, equal importance has been given to indoor air quality as we spend majority of our time indoors.Diffused modeIn Diffused mode, a baffle in the amplifier moves to block the front aperture, diverting air through the rear of the annular loop at a 45⁰ angle.1microns, including allergens, bacteria, pollen and mould spores. Activated carbon filters, which have been coated with Tris (Trishydroxymethylaminomethane) to increase their absorption efficiency, remove gases including NO2, formaldehyde and benzene. Our latest machine goes beyond standard tests.end-ofTags: dyson, air purifier, heater, cooler. Indoor pollution can come from outside when we open air brake cylinder the windows or doors, but it can also be produced from everyday activities in our home.DECCAN CHRONICLE   Published:  Feb 7, 2019, 1:51 pm IST Updated:  Feb 7, 2019, 1:51 pm IST Dyson Pure Hot+CoolTM air purifier heats in winter, cools in summer and purifies all year round.Nine meters of a condensed and sealed borosilicate microfiber filter captures 99. The machine automatically detects airborne particles and gases and simultaneously reports to the new LCD screen and Dyson Link app in real time, encouraging wellbeing and maintaining comfort levels in the home.Dyson adds powerful new sensors, real time LCD and increased filtration to its new Dyson Pure Hot+Cool air purifiers."Indoor generationEvery day we can breathe in up to 9,000 litres of air. Because the aperture is wider, this creates a more diffused airflow, uses less energy, generates less noise and purification effectiveness is maintained. Furthermore, the outdoor pollution can enter the home and when combined with indoor pollution sources like cooking fumes, cleaning products, pet dander and disintegrated faeces, can make indoor air quality equally or more harmful than outdoor air quality. We insist on developing technology that works properly, without compromise on any functions. Using this data, we made numerous iterations of our air apertures to make sure that our machine circulates the air effectively for whole and even room purification. The North region in India, also witnesses extreme temperatures ranging from 50 degrees in summer to as low as 4 degrees or lower in winter. This can cool you down in the summer while simultaneously purifying the room. Living in the era of the “indoor generation”, we are breathing in more pollutants indoors as we are spending up to 90% of our time behind closed doors.The bedroom, where we spend approximately one third of our lives can be a polluted place at home.Heating: 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. Dyson engineers go beyond industry tests and developed the POLAR test based on a bigger room size, with no added ceiling fan. To maintain airflow projection out the front of the machine, the baffle stays in place to deliver a powerful, frontward stream of purified air.Priced at Rs 52,900, the Dyson air purifier comes with a 2-year warranty period
