Coway air purifier – breathe easy (Model 1516D)

4.6Overall Score

Name: COWAY Air Purifier 1515D ‘Storm’
Price (RRP): $1399
Manufacturer: COWAY

In case you have not heard of Coway, it is a South Korean company that makes air purifiers and water filtration – similar tech in both. The Coway air purifier 1516D is its premium model.

Gadget Guy has been trialling the Coway air purifier model 1516D, one in the range distributed by Andatech. That is the same company that has Ionmax UV air purifiers, AlcoSense breathalysers, MedSense infrared thermometers, DriveSense dash cams and many more consumer brands.

Why a purifier and what to look for?

Most true air purifiers use a mix of filters – pre-filter (for larger visible particles or <PM10), HEPA (High-efficiency particulate air for micron-sized <PM2.5) and activated carbon (for noxious gas absorption). Some add UV and other sterilising light.

Currently, no filter traps more than 99.X% of everything. We are extremely suspicious of any filter that claims it traps and kills COVID or a similar virus.

Filters generally quote a CADR (clean air delivery rate in m3/minute or hour). For example, a typical bedroom 3x3x2.8m (about 25m3) has 25,000 litres of air to clean. Now, if you can close the windows and doors, CADR is not such an issue as once cleaned it remains that way until more ‘dirty air’ enters the room.

Purifiers either have a directional fan or just vent the air back to the room.

And then we look at ongoing energy and maintenance costs.

We use FAIL, PASS and EXCEED for our test paradigms. PASS means it is all that you can reasonably expect.

First impression – EXCEED

Its slightly larger than I imagined – 410 x 756 x 240 mm x 12kg and it is not on castors so you may have to heft it around. Being larger, it has a bigger filter system.

The design is classical and modern, and I like the glowing ring that indicates overall air quality. And I like that you can direct air out the front like a fan.

It is very easy to use – plug it in, turn it on auto and let it do its thing.

CADR – Exceed

8.2/492m3 minute/hour on maximum fan speed – will clean the air in a 25m3 area in three minutes

Filter efficiency – EXCEED

Coway is refreshingly honest about filtration. By the time it has passed pre-filter (fine screen), customised filter (kind of a fibreglass filter), Deodorisation filter (active charcoal) and the HEPA filter (coated in ginkgo and Sumac) it has trapped 99.5% of particles and 98% of harmful gases.

The combined effect is 99.99% removal of particles as small as 0.02um (PM2.0) – a strand of hair is about 50um.

You can adjust filter efficiency – sensitive, standard and insensitive. Though I am not sure why you would do this.
