It takes a lot of research and development to create a good product. There are standards that must be met. So it is an attractive product for the masses and a useful table. Dyson is one of the many brands that take testing methodology to the next level. Air purifiers in general have always succumbed to the usual CADR industry tests, and have done so for a long time, but the fact is, according to Dyson, that they only cover a limited area. So they’ve developed their own test method – POLAR, and we’re all gonna talk about it.

And before that: What’s an air purifier?

Stupid as the question may sound, it is relevant because in today’s market there are many products that claim to be air purifiers, but do anything but clean. The idea behind a good air cleaner is to clean the air and improve the air quality in your environment. Now it also helps to improve breathing, i.e. to make it easier to breathe. That’s the basic idea behind the air purifier. To make it effective, companies that support their own air purifier have a standard they follow and extra features to make it effective.

During the manufacturing process of an air purifier and knowing that it is effective, there must be a test method that must be passed. And the industry standard test method that every air purifier undergoes is CADR.

Test methods

CADR – What is it? How does it work?

CADR – Clean Air Delivery Rate is a standard test method developed specifically by the US-based Appliance Manufacturers Association. The general idea of the test is to make the consumer understand that – the product corresponds to what the brand claims. The test is based on the ANSI/AHAM AC-1 test – which you can read here if you want to know the grain size of the wire. The entire test is carried out in a room and exposes the air cleaner to contaminants. When the test is complete, it receives a CADR classification – which can be found on the side of the box or in the manuals.

On the picture above you can see that it is a compact device that measures 28.5 m3 and captures three particles to be precise: Dust, pollen and tobacco smoke on a sensor that monitors and controls a small test chamber. The fact is that this test has some disadvantages. First of all, only three particles and one sensor are detected, and in our daily world we are exposed to more than three particles. If you add up the equation for real houses, it doesn’t add up completely because the uncaptured particles end up in the environment. Another drawback is the length of the test, because it can be effective for the first half hour, as he claims, but what if it’s not every minute after that?

That’s where Dyson’s genius came in to run a test that would be effective.

POLAR – How can it be better? What makes it different from CADR?

Dyson calls his test POLAR, and no matter how cool the name sounds, the test itself is pretty impressive. The crux of the matter behind this test is that their air purifiers have to go into a real house and they have to work like a house. The POLAR test chamber has a size of 81 m3, has 9 sensors (compared to 1 in the CADR) and captures 5 particles and 11 removed gases.

Conceptually, CADR and POLAR have the same idea, but Dyson has taken the existing industry test standard to a higher level to capture more pollutants in the air and make it more effective. In today’s world, we are not only exposed to dust, pollen and tobacco smoke – because there are so-called ultra-fine particles that can go as far as they can – and their air purifiers are on a mission to capture PM 0.1 particles from the air.

Now you understand why you shouldn’t make your air purifiers cheaper and get a good reputation.

In addition to these extensive tests, Dyson conducts a comprehensive grid test – measuring air flow, velocity and direction, a HEPA filter efficiency test – to ensure the filters retain 99.95% of particles down to PM 0.1, gaseous contaminants – from furniture, stoves and finally acoustic tests – keeping them quiet while you sleep.

Dyson Pure Cool and options

Dyson Pure Cool is available worldwide, but different countries have different specific options. In Malaysia we have two types of cooling air cleaners – a tower fan and a personal air purifier. These air purifiers are designed for different applications – such as the Tower for large spaces and Pure Cool me for small spaces – but they are also treated in the field of air purification.

There is another version available in Singapore, the crypt.

What distinguishes cryptomir from normal cryptomir?

Today, Cryptomic is their special version of Dyson Pure Cool, which captures another specific chemical called formaldehyde found in new buildings, furniture and more. The reason that this is very important in Singapore is that the formaldehyde content in recently renovated buildings can reach more than 0.10 ppm, which is very serious – the more towers there are, the more the whole equation adds up. So it is a Singaporean service, and in this case it is logical that Kryptomix is available in certain regions.

But for what it’s worth, Dyson Pure Cool does the same POLAR test and does its best to make sure the air you and your loved ones breathe in your home is healthy. Click here to buy your own Dyson Pure Cool
