Dyson's Pure Hot+Cool air purifier shows how dirty your house is - in real-time

Now you can breathe easy, finally!

Dyson isn’t just satisfied with cleaning up your rugs and cellars.

It’s now aiming to properly clean up your lungs too with the Pure Hot+Cool air purifier. It’s only been a year that British engineering brand Dyson entered the Indian market but seems like their floor care and air care products were custom-made for our conditions. Successor to the Pure Cool air purifier, the new Pure Hot+Cool adds a few new tricks while bolstering its HEPA filter by 60% and 3x more activated carbon compared to the earlier generation. Supplemented by an army of sensors that include laser diodes, gas, temperature and humidity sensors, the new machine is intelligent enough to turn itself on and off, depending on the ambient air quality.

Additionally, a PTC heater built around the air multiplier allows it to heat the entire room, thanks to the 350 degree oscillation of the entire unit. Said to remove 99.5% of pollutants from a room, the Pure Hot+Cool can also work as a personal heater or fan by being angled up or down for the first time and the new diffused air flow mode makes it easier at close proximity by not blasting you with a jet of air. 

Set to go on sale starting today for 52,900 in either traditional white/silver or the eye catching blue/grey colour combination, it’s by no means the most affordable air purifier out there but if you’re looking for a well-designed, scientifically tested unit that provides you complete app control and historical info on your air quality, the Dyson comes out on top of the short list. Like all things the brand does, this is no half-baked, money-making machine. Backed by health experts and real-world tests, it seems to be the most effective method to get rid of that chronic cough. I’m waiting for my review unit to breath easy...

Can’t airbrush this anomaly out

Dyson’s recent studies of the Indian air quality reveal some inconvenient facts. Tackling a macro issue like air-pollution from a country like India, which has 14 of the world’s 15 most polluted cities, was never going to be an easy task. And while to find a more national solution might be in the hands of the government, change begins at home and that’s where domestic air purifier brands have focused their marketing dollars over the last few years. Dyson, in particular, is no stranger to finding challenging issues in the domestic environment and then taking a stab at it with all its engineering might.

Sam Bernard, Global Category Director - Environmental Control, Dyson, is keen to add that “at Dyson, we don’t want to make products that are just better than the rest, but a lot better than”. Reiterating that profit isn’t the driving force behind the efforts at Dyson R&D, they have fundamentally changed the way air moves in the room. Our scientific advisory board works closely with universities in Oxford, Cambridge and Kings College on air quality. At the launch of the Pure Hot+Cool air purifier in New Delhi recently, Sam also called Dr Vikram Jaggi, Medical Director, Asthma Chest and Allergy Centre up on stage to shed some light on the ramifications of indoor air pollution.

Facts like every breathing person inhaling air that is equivalent to smoking six cigarettes a day, life expectancy going down by 5-7 years in metros due to respiratory disorders, increase in viral infections amongst children etc were shared and they came as no surprise. What was alarming is that the general age of lung-related patients is decreasing to 30 - 35 years which earlier used to be around 60! 

According to WHO reports, air pollution is the third largest killer in the world and a good air purifier has to do three basic things - sense pollution, capture it and release clean air back into the room. To that effect, the POLAR test developed by Dyson is a lot more effective than the CADR tests used by a majority of air purifier brands to rate their products. It differs primarily in the way it measures indoor pollution and uses multiple sensors spread around a much larger room, rather than the single sensor and far to circulate the air in the CADR test.

The Dyson POLAR test is also conducted in a much larger room size (290sq. ft as opposed to 127sq. ft), using a total of nine sensors to measure air pollutants 300 times narrower than the human hair. Coupled with Dyson’s Air Multiplier technology, the clean air is projector across and around the room to ensure there are no zones or “pockets”, instead an even flow of filtered air throughout the room. Since the POLAR test is more akin to real world situations, it helps Dyson engineers design air purifiers that are more effective in all conditions using laser diode sensors, HEPA filters and activated carbon to combat indoor air pollution. While our own experience with their newest product, the Pure Hot+Cool is yet to be documented, keep watching this space for a full review on this site soon.
