Coway AP-1512HH  Features

Air Quality Sensor

With the remarkable Coway, you get more than just a quality device – its air quality sensor is truly extraordinary. This top-notch feature allows for adjustable sensitivity settings to provide an unbeatable clean environment.

Enjoy the customizable air quality control with Coway AP-1512HH. With three sensitivity levels – sensitive, standard and insensitive – you can always be sure that your environment has optimal cleanliness conditions! The device detects changes in the atmosphere through its sensor, allowing for tailored cleaning right at home or office.

The Air Quality Indicator next to the filter reset button will provide you with an accurate readout of your current air quality. The Air Quality Indicator can display a few distinct colors; blue indicates the air is good, purple meaning ordinary pollution levels and red signifies high amounts of pollutants in the atmosphere.

Auto Mode

Forget about manually adjusting settings to maintain the healthy air quality in your home—with Coway AP-1512HH, you can rest easy knowing that the device automatically works its magic. It’s intelligent auto mode collects data from a built-in sensor and quickly adjusts fan speed accordingly for maximum comfort!

I experimented with Coway’s Auto and Eco modes in both my living room, study room, and bedroom. I vastly preferred the auto mode when it came to purify the air in my living area as Coway did a stellar job running on this setting – however, for bedrooms or studies I always opted for ECO mode!

ECO Mode

ECO mode is an outstanding alternative to the Coway AP-1512HH and my personal favorite. If I had to explain how it works in a straightforward manner, ECO mode can be thought of as being akin to auto mode.

With Coway’s ECO mode, you can rest easy knowing the device will be conserving energy and protecting your air quality. Its cutting-edge sensor monitors the environment 24/7 to ensure cleanliness is maintained while saving money on electricity bills – all automatically!

Vital Ion System

This Coway model is outfitted with an Ionizer that can be easily toggled on or off. When you press the button, you’ll witness a reassuring LED light up – letting you know it’s been activated and is ready for use!

When the button is inactive, it means the device is turned off. By utilizing a four-stage filtration process, this bipolar Ionizer delivers an electrochemical reaction that reduces airborne particles.

The great thing about the Ionizer is that it comes with a switch, meaning you can turn it on when needed and won’t need to keep it running all day. In the following section, I will discuss in-depth information concerning Ionizer technology and its amazing filtration capabilities.


For those who want to use their air purifier for a designated period of time, the timer is an ideal feature. It can be set up to 1h, 4h, or 8h and will automatically switch off once the allotted duration has elapsed. This way users don’t have to worry about remembering to turn it off themselves!

Filter Reset Indicator

Coway air purifiers come with a standard filter reset indicator, meaning you won’t have to worry about when it’s time for the filter replacement – Coway will notify you! Although I’d still recommend that you double-check your filters every so often just in case. With this helpful feature from Coway, maintaining an optimum environment is easy and effortless.

Coway AP-1512HH Design and size

Experience top-tier craftsmanship with Coway AP-1512HH – a signature air purifier made from premium quality plastic. Its sturdy frame can be customized in two dazzling finishes, adding sophisticated elegance to any living space.

The Coway AP-1512HH is the perfect balance of sophistication and functionality, with its chic color palette and luxurious look. Situated on top of this device lies a control panel that showcases buttons and indicators to make it easy for any user to operate – I will go into more detail about them during the next section.

Control Panel

Coway AP-1512HH

Control Panel has a power button, Quality speed control button, ionizer control button, timer button, and a filter reset button. Notice the indicators above each button. If your Coway AP-1512HH is positioned in front of you with its control panel facing towards you, then directly to the right beside the filter reset button lies the Air Quality Indicator. When a button is pressed, an indicator lights up above it and a beep sound can be heard. It’s as easy as that!

Size and Dimensions

At 12.34 lb, the AP-1512 air purifier is a bit heavier than other devices of its kind. Nevertheless, it’s still highly portable due to its convenient transfer handle—plus with dimensions of 16.81 x 9.56 x 18.30 inches, you won’t have any problem carrying this device wherever you need to go!

Coway AP-1512HH  Room Coverage and CADR

Make your home a breath of fresh air with the Coway AP-1512HH. This powerful air purifier is specially designed for rooms up to 361 sq ft, perfect for day-to-day living spaces like living rooms, kitchens, and offices.

With its ECO Mode feature and Auto mode, you’ll be able to make sure that no electricity goes wasted! Plus it has impressive CADR ratings too – so don’t waste another second on breathed-in allergens or dust – get rid of those baddies from your space before they settle down!

Get rid of pesky allergens and irritants with the Coway Mighty Air Purifier – designed to clean rooms up to 361 sq. ft., it packs an impressive punch! With a Clean Air Delivery Rate (CADR) rating of 240 for pollen, 246 for dust, and 233 cubic feet per minute (cfm) for smoke, this purifier will help keep your air smelling fresh & clean.

Coway AP-1512HH Filters

The Coway AP-1512HH is outfitted with an advanced 4-stage filtration system.

First, the pre-filter captures large particles such as dust or pet hair.

Then a carbon filter eliminates unpleasant odors and volatile organic compounds (VOCs).

The true HEPA filter then efficiently grabs the remaining microscopic pollutants like mold spores, bacteria, and allergens.

As an added bonus, you can opt for the fourth-stage Ionizer to help cleanse your home of even more impurities!


The pre-filter is the foundation of filtration, designed to intercept animal hair, dust particles, and other large debris.

Cleaning your pre-filter about every two weeks is key for optimum device performance. This will keep other filters in the system functioning properly and make sure you get a comfortable working experience. I would especially recommend regularly cleaning the pre-filter if there are pets at home, just to be extra safe!

Carbon filter

The Coway AP-1512HH contains a carbon filter that is uniquely designed for maximum effectiveness. Not made of simple carbon pellets, the fibrous material used in this air purifier has been coated with activated carbon to trap unwanted chemicals and airborne odors – from cigarette smoke to pet smells and beyond.

Rather than utilizing carbon, Coway opts for an odor filtration method called a ‘deodorization filter.’ While this may seem to confound to some readers, the name is merely a technical term – in reality, it’s nothing more than a good old-fashioned carbon filter.

True HEPA filter

As the third stage of filtration, the HEPA filter boasts true efficacy as it captures 99.97% of airborne allergens including pollen, mold spores, dust mites, pet dander, and even particles as small as 0.3 microns in size! However, due to its delicate nature, this air purifier must not be washed with water – no matter what the situation is.

Coway may not have gone into depth when presenting this innovative technology, but I was determined to get the scoop. So, I contacted them directly and uncovered all there is to know about it!

Coway air purifiers are equipped with powerful, self-regulating ionizers that capture airborne particles and wash the air in your house effectively.

When you switch on the Ionizer, voltage is applied to a series of in-built needles. This process generates electrons which are released into the air and cling onto molecules present there, forming ions as a result.

Coway AP-1512HH air purifier Performance

After testing all air purifiers currently on the market, I have determined that Coway AP-1512HH is best suited for spaces up to 361 sq. ft. My process consists of meticulously measuring each device’s performance in a room of specified dimensions over an hour-long period as well as personally utilizing them daily; after careful consideration, I can confidently come to a final verdict.

I generally suggest that users begin with the air purifier set to its highest speed, maintain this for roughly 10-20 minutes, and then switch it lower. Coway offers a plethora of advanced features which make these calculations unnecessary – no guesswork required!

During the tests, I avoided ECO mode since it is hard to measure its performance and display results.

We were amazed to discover that the Coway AP-1512HH was one of the most efficient air purifiers we tested, as it quickly and effectively removed large particles in merely 30 minutes. It proved itself capable at its highest level of performance!

Replacement Filters: Get your replacement filter set of 2 carbon filters and 1 True HEPA Mode for only $55!

Save money with Coway AP-1512HH’s yearly operating costs of just $100 – this includes filter replacements and electricity.

Electricity Costs:

The Coway AP-1512HH is powered by an outrageously powerful 77W motor. I was surprised at the level of power this appliance had, yet with its ECO mode and other features factored in, it’s no surprise that Coway makes for a relatively low-energy consumer.

Don’t be afraid of the $6 increase in your electricity bill after running Coway Mighty on third fan speed for 30 days–it’s totally worth it! Plus, with ECO mode and other lower fan speeds, you’ll consume even less energy.

For only $4 a month, you can enjoy the maximum speed of our Coway mighty air purifier running for twelve hours daily. To get an accurate prediction of your electricity usage and cost based on local rates.


At the lowest speed, the purifier is virtually silent – a peaceful whisper. When up to the second level, it emits a gentle hum that’s just loud enough for you to notice its presence.

At its highest setting, the purifier produces a noticeable hum. To quantify this more clearly, at its lowest speed it is 41.4 dBA; medium is 44.6 dBA, and high reaches 63.5 dBa.

With Coway, no calculations are required to ensure your air purifier is operating efficiently. Instead, the advanced features built-in make it easy; simply start on high speed for 10-20 minutes and then switch to a lower setting.

If you wish to maintain restful sleep, it is recommended that the purifier in your bedroom be kept at low or eco-mode speeds. The sound emitted from high-speed settings can interfere with peaceful slumber.
