To engineer a good product, a lot of Research and Development is required. There are standards to follow. Therefore, making it an appealing product for the masses and brings benefits to the table. Dyson is one of the many brands that takes their testing methodology to a different height. Air Purifiers in general has always succumbed to the usual industry-wide CADR testing and it has been around for a long while but the thing about that particular test is that – according to Dyson, covers limited areas. So, they came up with their own testing methodology – POLAR and we are going to talk all about it.

Before that, what is an Air Purifier?

As silly as the question sound, its relevant because in the current market there are a lot of products “claiming” to be air purifiers but does everything else other than purifying. With that out of the way, the idea behind a proper Air Purifier is to clean the air and to improve the air quality in your living environment. Now this also helps in improving your breathing condition – that is to breathe easy. That’s the core idea behind Air Purifier. To make it effective, the companies behind their own air purifier have a standard they follow and additional features to make it effective.

In the process of making the air purifier and knowing that its effective, there needs to be a testing methodology it needs to go through. And the industry standard testing method where every air purifier goes through – it’s CADR.

Testing Methodology

CADR – What is it? How does it work?

CADR – Clean Air Delivery Rate is an industry standard testing methodology that was specifically designed by the Association of Home Appliance Manufacturers based in US. The whole idea behind the test is to let the consumers know that – the product is up to what the brand claims. The test is based on ANSI/AHAM AC-1 Test – which you can click here to read if you want to know the nitty gritty part of it. The whole test takes place in a chamber and expose the air purifier to air pollutants. Once the test is done after a certain duration, it is then given a CADR Rating – which you’ll either see printed on the side of the box or in the manuals.

In the image above, you can see it’s a compact chamber – which measures in 28.5m3 and it captures three particles to be specific: Dust, pollen, and tobacco smoke on one Sensor which maps and monitors the small test chamber. Now the thing about this test is that it has its fair share of flaws. For one, it only detects three particles and one sensor only and in our everyday world we are exposed to more than three particles. When you add the equation into real homes, it doesn’t quite add up because the particles that aren’t captured gets released into the environment. The duration of the test is another flaw because it may be effective in the first half hour as it claims to be but what if it isn’t every minute after that?

This is where the genius at Dyson stepped in to make a test that’s effective.

POLAR – How is it better? What does it differ from CADR?

Dyson calls their test POLAR and as cool as the name sounds, the test itself is pretty impressive. They key take behind this test is that their air purifiers are going to real homes and it needs to perform like it is in one. That said, the chamber of the POLAR testing is 81m3, has 9 sensors (vs 1 sensor in CADR) and captures 5 particles and 11 gases removed.

Conceptually speaking, the CADR and POLAR share the same idea but Dyson took the existing industrial standard of a test and crank it up a notch to be able to capture more pollutants in the air and make it effective. In today’s world, we are exposed to more than just Dust, Pollen and Tobacco smoke – because there are particles called Ultrafine particles which can go as small as it can – and their air purifier is on a mission to capture PM 0.1 particles from the air.

Now you see why you shouldn’t cheap out on your Air Purifiers and get-well reputable ones.

Perks of POLAR Testing for Dyson Line of Air Purifiers

On top of that already in-depth testing, Dyson pushes further by doing Full Grid Test – measuring the air flow, velocity and direction, HEPA Filtration Efficiency Test – making sure that their filter captures 99.95% of the particles as small as PM 0.1, Gaseous pollutants – which comes from furniture, cookers and finally, Acoustics testing – to keep them quiet and still protect you as you sleep.

Dyson Pure Cool and the Variants

Dyson Pure Cool is available all over the world, but different countries get different specific variants. In Malaysia, we have two different Pure Cool air Purifiers – a Tower Fan and a personal air purifier. These air purifiers are meant for different use case – like the Tower is for larger spaces and Pure Cool me is for smaller spaces – but it gets the same treatment in terms of cleaning the air.

There is another version that’s available in Singapore, which is the Cryptomic.

What makes the Cryptomic Different from Normal ones?

Now Cryptomic is their special variant of Dyson Pure Cool that captures another specific chemical called Formaldehyde which you can find in newly constructed buildings, furniture and so much more. The reason why in Singapore it’s a big deal, it’s because Formaldehyde rates can go higher than 0.10 ppm in newly renovated spaces and that is profoundly serious – plus, the fact that there are a lot more high-rise buildings present, the whole equation adds up. Hence why it’s a service in Singapore and in this case, makes sense why Cryptomic is available in select regions.

But for what it’s worth, Dyson Pure Cool gets the same POLAR testing across and make sures that air you and your loved ones breathe at home is safe. Click here to purchase your own Dyson Pure Cool.
