Coway air purification process

Most purifiers from the Coway utilise a four stage filtration process which includes the following steps:

Step 1 – Pre-filter

Designed to capture and filter large particles like hair, fur and dust

Step 2 – Fine Dust Filter

Filters small and tiny particles like fine dust

Step 3 – AC Deodorisation Filter

Removes bad odour and harmful gasses

Step 4 – HEPA Filter

Removes cigarette smoke, viruses, germs and fine dust

This process makes sense as the washable filters tackle most of the air filtering before the true HEPA filter steps in to clean the air quality during the final step. Meaning a longer life for the HEPA filter than if it was the first step of the purification process.

Top Coway air purifier product

As mentioned the AP-1512HH is a very well-reviewed product and boasts a solid range of features such as it’s vital ion system which ionizes particles in the air to reduce the amount of particles being passed through the filter.

The purifier also features an eco mode, filter replacement indicator, air quality indicator light, and auto mode to adjust fan speed as timer settings.

The unit itself is quite large and can tackle room sizes up to 361 sq.ft, therefore is a good candidate for middle sized rooms such as living space, spare rooms, home offices or medium sized apartments.

Replacement filters for the AP-1512HH cost around $40 and should last around a year for the HEPA filter and six months for the carbon filters used for odor control.
