On average, we typically take in between 9,000 to 11,000 litres of air a day, with about 70 percent of that consumed indoors. That’s plenty of air, and in today’s context also means a higher volume of pollutants taken into our systems depending on where we’re at.
Simply put, the air we breathe has progressively gotten dirtier year on year since we started measuring pollution levels. A study released by the World Health Organization last year was able to prove just how bad things have gotten in recent times, with about seven million deaths being reported yearly as a result of exposure to unsafe fine particles suspended in the air we breathe every day.
Unsurprisingly, thishas all led to more attention focused on air purification technology,with the air purifier market having grown considerably over the pastfew years and places like China and India—countries withhigher-than-usual pollution ratings—leading sales figures.
That said, it’sworth noting that with so much trust placed in air purificationproducts, especially by residential consumers, there should obviouslybe heavy emphasis placed upon the efficiency of the tech that airpurifiers run on.
As expected, tech giant Dyson—giants in household appliances and beauty technology—are one of the brands aiming to set the standard in regards to air purifier technology testing, and are trying to improve the quality of air purifiers in general.
Clearing The Air
Recently, we had the opportunity to pay a second visit to Dyson’s Development Centre in Johor Bahru. This came after our first visit in December 2018, where we spoke to their Global VP Of Engineering & Operations Scott Maguire to talk about his views on Malaysian engineering talent.
This time, Dyson invited us to have a closer look at their POLAR testing method that they use to develop their air purifiers, and demonstrated in detail the differences between this method and conventional methods used in the rest of the industry.
To lay down the basics, air purification works in three steps—sensing unclean air, then filtering it, and finally projecting that clean air throughout the space the purifier is in. While this is the modus operandi most air purifiers function on, Dyson thinks that the current method to test the efficiency of these purifiers remains insufficient.
Since the 1980suntil today, most air purifiers have been tested using the CADR(Clean Air Delivery Rate) method that provides a score based on theamount of clean air a purifier can provide within a fixed amount oftime. Unfortunately, this method omits the most important metric ofall—how efficient the filtration is, or rather much cleaner yourair gets once its been filtered.
Basically, an air purifier with a high CADR score only guarantees that you’re getting cleaned air quicker, but not necessarily cleaner, which is why Dyson introduced the POLAR testing method to compensate for these gaps and to be used to test the efficiency of all their air purification products.
At Dyson’s JohorBahru facility, we were given the opportunity to witness the variousways in which POLAR is more comprehensive than the CADR standard.
For example, the POLAR standard is conducted in a space that is more akin to a real-life living room, with a space of 290 square feet as opposed to the CADR measurements of 127 square feet. It also uses 9 different detectors or monitoring points as opposed to CADR’s single point system.
According to theengineers we spoke to, these parameters were all intended to mimictrue-to-real life conditions and to ensure that their products wereall able to perform in the real world just as efficiently as in thetest facilities.
For a more comprehensive explanation on how POLAR is able to improve the quality of air purification, watch this video:
So what does all this eventually mean for the end user?
According to Dyson, their air purifier products—specifically their Pure Cool series—are able to remove up to 99.95% of particles from the air and filter out particles as small as 0.1 microns, and more importantly, are also able to make sure that whatever enclosed spaces they operate in gets a good coverage of clean air.
Translating Into Something Significant
All this extensivetesting perhaps goes some way to explaining just why Dyson’sproducts are relatively costly when compared to products from theircompetitors, and also how they’ve managed to establish quite a bitof a reputation for product quality and efficiency.
Supplementing this, it’s worth noting that the POLAR testing chamber in Malaysia is just one of the resulting outcomes of Dyson’s GBP3 billion outlay into their entire Johor Bahru facility.
More significantly, it’s one of only two such chambers worldwide, with the other one in their main research facility in the UK.
In the grand scheme of things, this development is pretty significant as Malaysia is now seen as a class-leading developer of a technology that is becoming more and more important around the world.
Case in point, POLAR is also now also used in China, with the China Household Electric Appliance Research Institute (CHEARI) now incorporating POLAR as a testing standard for Chinese air purifier products in Beijing.
Making A Malaysian Mark
The next step forDyson is now to get the Malaysian market itself to sit up and payattention to the importance of having clean air—something that’sbecome incredibly pertinent recently.
Speaking to Pete Duckett, Dyson’s Technology Development Engineer of Environmental Control, we learned that Dyson’s greatest challenge at the moment was to get Malaysians educated on the importance of this particular technology.
“It’s a bigeducation challenge and I think the biggest block in trying to sellthis tech is showing people,” Pete said. “It’s similar with theoriginal vacuum cleaner, where we were the first to create a vacuumwith a clear bin.”
“Logic would say that you wouldn’t want to see the dirt and dust, but the moment you show the results you have an immediate feedback that has a big impact on the consumer,” he said.
He admitted thatthis would be harder to do with air purification due to theultra-small particles that usually can’t be seen with the nakedeye, but he thinks that at least with the more obvious side effectsof pollution (such as the haze and airborne diseases), people wouldbe more inclined to consider solutions for cleaner air at home.
“Malaysian airquality is also now 50 percent over the recommended WHO guidelines,”he said “And people started noticing these, so we started packagingour air purification products with our sensor technology to givereliable metrics so people can see the air being cleaned.”
Looking ahead, it will be interesting to see how Dyson in Malaysia will continue to develop in terms of product R&D and market growth.
Already, they’ve committed plenty to making their Malaysian facility one of their most vital development centres, now it’s time for them to do the same for the Malaysian consumer market.
