Air pollution is a scourge for humankind. According to the latest statistics from the World Health Organization (WHO), 9 out of 10 people worldwide breathe air with high levels of pollutants. Close to 7 million people lose their lives over air pollution-related diseases annually.

The most dangerous air pollutants are the tiny airborne solid or liquid particulate matters – PM 10 (particles smaller than 10 micrometres in diameter) and PM2.5 (smaller than 2.5 micrometres). WHO classifies them as Group 1 carcinogen: an agent proven to cause cancer in humans. The smaller they are, the more dangerous they will be because they can penetrate further into the lungs and enter the bloodstream more easily. These airborne particulates can also cause bronchitis and other respiratory diseases, and aggravate asthma and many other allergies. They are also linked to birth defects and heart disease. Few of us can afford to ignore the serious health hazards posed by the airborne pollutants to us and our families, particularly young kids.

Hong Kong, given its ultra densely populated urban areas packed cheek by jowl with high rises and the perennial heavy vehicular traffic, has been beset with a mounting air pollution problem. Smog hanging above the cityscape is a regular sight and Hong Kong’s visibility is less than 8 kilometres for 30 percent of the year. The ambient, or outdoor, polluted air in Hong Kong carries PM10 and PM 2.5 from a wide range of sources, including pollen and running engines; sulphur dioxide from burning fossil fuels; and oxides of nitrogen also from cars and ships’ engines.

On a day of particularly foul air, the government usually advises individuals with respiratory diseases to stay indoors. If you think that your homes are a sanctuary of fresher air, think again. Recent studies conducted by the U.S. Environmental Protection Agency find that indoor air can be up to five times as polluted as outdoor air. Aside from the outdoor air pollutants making their way indoors through windows or cracks in poorly sealed buildings, it’s estimated that the average home contains about 63 synthetic chemicals for a total of about 38 litres of hazardous materials. The indoor use of pesticides, cleansers, paints and varnishes and air fresheners as well as carpets and the foam in furniture distribute toxins throughout. These include Formaldehyde, ethylene-based glycol ethers and terpenes that linger indoors and they are linked to allergies and asthma. Flame retardants widely used in casings of computers, as well as mattresses and upholstery contain the harmful polybrominated diphenyl ethers.

Research indicates that city-dwellers spend approximately 90 percent of their time indoors. Thus, the risks to health for many people in Hong Kong can be much greater due to their exposure to air pollution indoors than outdoors, not to mention the increasing threat of flu virus that makes their way indoors and spreads at home, owing to the city’s ever-lengthening flu season. An effective air purifier is the solution to safeguarding your and your family’s wellbeing. The air purifier should be able to circulate purified air throughout the entire room, not just limited to its surrounding area. It should have the capability of filtering out PM 10 and PM2.5 as well as other allergens, toxic chemicals and gases and lock them in securely. It should also be ‘smart’ enough to monitor the levels of pollutants constantly and activates air purification whenever necessary. Meeting all these essential criteria is the new Dyson Pure Hot+Cool HP04 – the real technological game changer for indoor air purification.

Powerful Projection of Purified Air

To get the full benefit of indoor air purification, it’s vital that the air purifier is able to distribute the cleaned air throughout the entire room. Dyson Pure Hot+Cool HP04 simultaneously purifies, heats or cools the purified air, and then projects it using its unique Air Multiplier technology. With 350 degrees of oscillation, it projects and circulates more than 290 litres of thoroughly cleaned and heated or cooled air per second to ensure your entire room is purified with cleaned air.

Automatic Pollutant Detection and Removal

A ‘smart’ air purifier for the 21st century healthy living should have cutting-edge technology capable of automatically detecting the airborne pollutants and harmful gases and then activating its pollutant removal function whenever necessary. This not only maintains the purification, it also helps conserve energy. Dyson Pure Hot+Cool HP04 features three intelligent sensors that detect airborne particles and gases in real time and report them. This is achieved with its unique algorithm that processes the input to provide the real-time indoor air quality reports. The purifier’s built-in LCD screen updates you on which particles and gases have been detected and the current temperature. Simply switching on the Auto Mode and let Dyson Pure Hot+Cool HP04 maintain the air quality and your target temperature on its own.

Meanwhile, with the Dyson Link App downloaded from Apple Store and Google Play, you can monitor the indoor pollution level, schedule the purification, and see how many hours of filters’ life left, anytime and anywhere. The App also lets you set the oscillation angle – from targeted to wide, even air distribution.

Secure Pollutant Lock-in

The most important assurance an effective air purifier should offer is that it securely captures and locks in the airborne pollutants and gases/odours so that they do not leak back out and return to indoor circulation. Dyson Pure Hot+Cool HP04 features 360-degree sealed filtration. The filtration system combines an activated carbon filter and a Glass HEPA filter. The carbon filer is engineered using a dense layer of carbon crystals treated with oxygen to make it more porous so that the carbon’s increased surface area effectively traps gases, including formaldehyde, benzene and NO₂. The Glass HEPA filter, made with 29 feet of borosilicate microfibres pleated over 200 times, captures and locks in 99.97% of microscopic allergens and pollutants as small as PM0.3.

It’s time to transform your indoor space into a genuine pollution-free sanctuary. Ideal for all seasons, Dyson Pure Hot+Cool HP04 is the only air purifier designed and tested to simultaneously purify and heat/cool a whole room evenly. For more details, please visit
