The air we breathe has never been filthier, and air purifiers have never been easier to sell.
But do they deserve your hard-earned money? While those suffering from constant mysophobia would buy anything that promises “clean” at the drop of a hat, the Pure Cool, with its visual display on the LCD screen and real time tracking of air pollution levels via the Dyson Link app would be nothing short of godsend for these obsessive souls.
Jokes apart, air pollution is as real a threat to our health and well being as a pending nuclear war. Endless nastiness in the air is not just city, region or season specific. Outdoor and indoor air quality has taken a huge hit in the past few years and it just keeps deteriorating. Little can be done to what happens outside, but indoor air quality can be checked to keep the confines of your home clean.
Allergy sufferers aren’t the only ones likely to benefit from it. The Pure Cool air purifier comes with double the filters from the previous generation and sweeps up bacteria, pollen, toxins and other indoor pollutants and the sophistication of the unit adds aesthetic value to your living room or bedroom.
Design: The Ring
The Pure Cool air purifier isn’t very different from its predecessor - the basic design of the ring or the elongated aperture resting over a cylindrical base unit. Though now, all the cleaning action of air purifier can be seen in action on the LCD display, which wasn’t part of the previous generation and adds greatly to its appeal.
The base can be set to be stationary or rotate up to 350 degrees, and control the blast of air via the app or the sleek remote that comes along with the unit. Unlike the Pure Hot + Cool Link, this too comes with a magnetic remote. Though it just takes a few minutes to link it to your home wifi, it’s easy peasy from this point on.
The function: Breathe easy
The two-stage filtration system is the heart of this machine. It’s improved further from the previous model to gobble up up to 99.95% pollutants in your indoor environment. The carbon filter, which was part of the glass HEPA filter in the Pure Hot + Cool Link, has now found its own space inside the cylindrical design.
You can either turn it on manually or through the app and see the air quality in your city and room of use at any given time. The graph on the LCD display constantly shows the sensors in action. Light a cigarette in the room or spray on perfume, and the fan (preset on Auto mode) goes berserk, picking full speed as air quality takes a dip. You’ll find it in full ninja mode till it gets rid of the newer smells in the room.
What’s also different from the older models is the fact that the purifying fans won’t be adding to the chill in winter months. Imagine fighting pollution in New Delhi in the last quarter of the year and your purifying enthusiasm dies as soon as the blast of cold air hits your face. You’d rather choke on the increased NO2 than add to the chill. Dyson engineers solved this problem with the Pure Cool air purifier. There is now the added feature of dispersing airflow backwards and spreading it around the room, rather than in your face. Winter months needn’t mean airborne nastiness won’t be sucked up.
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 just 11.8m2 (127 sq ft) in size, with an added fan to circulate the air - and only one sensor to measure air quality. It is not representative of the average living room environment. Finding this test method to be unrepresentative of an average real life room sizes and situations, Dyson engineers created a lab test called the POLAR test. It is based on a larger room size of 27m2 (290 sq ft), with no added fan as we don’t use fans in peak pollution winter season in India. The air purifier is placed in corner of the room which is how it is in real life environment. 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. Analysing the data across all nine sensors lets Dyson engineers ensure the Dyson Pure Cool air purifiers deliver a uniform cleaning performance throughout the whole room.
Dyson Pure Cool verdict
Dyson Link app keeps an eye on air quality, temperature and humidity and there’s no one else in the market who have gone through the hassle of conducting as many researches as Dyson have. Pure air isn’t only for allergy sufferers. Of course there’s no way to verify the data that’s displayed on the app outside of lab conditions, so we go with the assumption they’re as accurate as they claim to be. If you can see in real time the quality of the air you breathe, the air quality broken down right on your smartphone screen, spend would be a tad more justified.
