    The Coway AP-1512HH has a pretty awe-inspiring design which differs it from most other air purifiers out there. The near square-shaped unit has a sleek black finish with a distinctive circular white decorative pattern at the front, giving its looks plenty of polish.

    This air purifier is made for smaller spaces as it measures just 16.8 inches wide, 18.3 inches tall with a depth of 9.6 inches and weighs 15.41 lbs.

    4 Stage Filtration System

    To cater to most people’s air purification needs, the Coway Mighty Air Purifier has four stages of filtration.

    The pre-filter uses a micro mesh which traps large particles such hair, lint and fur. The 2nd filter, the odor filter, captures even smaller particles as well as gases and bad odors to leave your room air much more fresh and breathable. The True HEPA filter removes 99.97% of airborne particles such as bacteria, pollen and smoke.

    In addition to the three filters, there is an optional Vital ION which creates negative ions that charge the air thus causing harmful particles and viruses to be eliminated.

    The control panel on the Coway is rather good quality. It features five easy-touch buttons which are nicely spaced out for ease of use, as well as indicator lights to give you a clear overview of the current settings.

    Power – Turn the unit On/Off.

    Speed – This button is used to set the fan speed to one of five settings (1, 2 , 3, Auto, Eco).

    Ionizer – Activates the optional Ion feature.

    Timer – The timer button can pre-set the unit to turn off after either 1, 4 or 8 hours.

    Filter Reset – After you’ve replaced a filter, you press this button so the filter timer is reset.

    Air Quality – This light indicates the current air quality of the room. Clean (Blue), Polluted (Dark Purple), High Polluted (Red).

    Energy Efficient

    This model has been given an Energy Star approved seal and has gained much praise amongst users for its energy efficiency.

    Pleasingly, there is a dedicated Eco mode which stops the fan if no air pollution is detected by the sensor for at least 30 minutes.

    Filter Maintenance

    Happily, the Coway is one of the easiest air purifiers to maintain.

    The only filter which needs cleaning is the pre-filter. This filter should be cleaned every 2-4 weeks, based on using the unit in an environment with standard air quality.

    Onto filter replacement. The True HEPA filter should be replaced once per year, while the Carbon filter should be replaced every 6 months. The unit is fitted with filter replacement indicator lights so you know exactly when each filter should be replaced.

    Guarantee: 3-year limited warranty.


    The award winning Coway AP-1512HH Mighty Air Purifier outdoes many larger, more costly air purifiers due to its above-average air purification and high energy efficiency. Thanks to its small size and remarkable quietness this is a very flexible unit that you can use anywhere in the home.

    It’s only notable shortcoming is that it lacks the capability to effectively eliminate odors due to the limitations of its pre-filter. So if odor problems are a primary concern we’d recommend you look elsewhere.

    Overall, a great air purifier that manages to live up to its hype.
