44% de réductionI have done a lot of research on the Coway AP-1512HH. My wish finally comes true. I always wanted to test it personally and see with my own eyes all the good claims written on the internet about this device. The price that Coway offers for AP-1512HH can hardly be found elsewhere. After all, Coway is a global brand.
Coway Mighty is designed for rooms up to 361 sq. ft. It uses 4-stage filtration, which includes an ionizer that can be turned off or on as needed. I tested Coway for a while in a variety of rooms and conditions. I can say that this is one of the few devices that I use almost every day.

Design and Size
Coway AP-1512HH is defined by top-quality craftsmanship. The plastic is of excellent quality. Every part lies in its place, and everything is sealed correctly.
Coway Mighty can be bought in white or black color. But it is also possible to combine the frame’s color located on the front panel. AP-1512HH is built in a squared form with rounded edges. It looks elegant.
There is a carrying handle on the back right at the top of the device. I noticed something similar in Winix 5500-2 and Winix C535 air purifiers. Because of the handle, Coway AP-1512HH is easy to carry, and there is no possibility of it just slipping out of your hand.
Due to the choice of colors and its luxurious look, the Coway AP-1512HH will fit into almost any ambiance. At the top of the device is a control panel, with buttons and indicators, which I will write more about in the next section.
Not only will this air purifier uplift decor in the room, but it will also filter the air at a rapid speed. Check the Coway Mighty tests and see how good it is.
Control Panel
All buttons are located on the control panel (power button, speed control button, ionizer control button, timer button, and filter reset button). There are indicators above each button. If you place the Coway AP-1512HH in front of you, on the control panel, all the way to the right, right next to the filter reset button is the Air Quality Indicator. The buttons do not light. Only the indicators above the buttons are lightened. A beep is heard at every push on a button.
What I really liked about the Coway AP-1512HH model are the combinations you can do with buttons. For example, you adjust the air quality sensor’s intensity by pressing the speed and ionizer buttons for 2 seconds.
Or, if you want to turn off the Air Quality Indicator, you need to hold your finger on the ionizer button for 3 seconds. I will explain the air quality sensor’s intensity in more detail in the next chapter of the Coway AP-1512HH review.
Airflow
The Coway AP-1512HH draws air directly from the front and through vents on the left, right, and bottom. After that, the air is filtered through 3 basic filters and through the Ionizer if it is turned on. Filtered and clean air comes out on the upper side of the device, vertically upwards.
When positioning the device, get assured that nothing is placed within 22 inches above the machine.
Size and Dimensions
The AP-1512 air purifier weighs 12.34 lb. When I compare it with other devices, it is a bit heavier. However, transferring from location to location will not be a big problem, as the transfer handle is convenient. The exact dimensions of the device are 16.81 x 9.56 x 18.30 inches.
What’s in the box?
When you buy Coway Airmega, you will get 1x Coway AP-1512HH, 1x True HEPA filter, 1x Carbon Filter, 1x User Manual, and 1x Warranty Guide.
Personally, I think that the significant disadvantage is that only one carbon filter comes with the device because this filter needs to be changed on average every 6 months. Since the True HEPA filter needs to be changed every 12 months, I think it would be great if more than one carbon filter comes with the device.
Coway AP-1512HH Air Purifier Video Review
Finally, I got a chance to test Coway Mighty AP-1512HH. This magnificent air purifier did not disappoint me. I hope you will enjoy all the features this air purifier offers.
Coway AP-1512 Features
Air Quality Sensor
This kind of option is expected from a quality device like the Coway.
However, I didn’t expect the air quality sensor to be this advanced and that you could adjust sensor sensitivity. The Coway AP-1512HH offers the ability to fix the sensor’s sensitivity at three different levels. The options you can choose are sensitive, standard, and insensitive. The names themselves say how sensitive it is. The sensor will measure the air quality in the room where the device is located.
The current air quality will be displayed on the Air Quality Indicator located next to the filter reset button. The Air Quality Indicator can show three different colors. When the indicator is blue, the air is of good quality. When the indicator is purple, the air is ordinarily polluted. When the indicator is red, the air is highly polluted.
How to Adjust Air Quality Sensor?
By the default, Coway air purifier is set to standard sensitivity. If pollution levels are high after two hours of working or if the pollution level is low, but the air quality does not seem good to you, you can adjust the air quality sensor.
You can adjust the air quality sensor by following these steps:
- Press speed button and Ionizer for two seconds
- After that, you will hear a beep with 1-second intervals. The speed indicator will blink and show you the sensor sensitivity.
- Now you can set the desired sensitivity level by pressing a speed button. Go for low sensitivity if the room’s pollution stays at the highest level for longer than one hour.
- In the end, you need to hold for two seconds the ionizer and speed button to resume regular operation.
You can play with this option and adjust the sensor’s sensitivity to suit you best.
How to Maintain The Air Quality Sensor?
The air quality sensor should be cleaned every two months.
The cleaning process is straightforward. Open the sensor cover located on the side. Using an ear cleaning brush, clean all parts of the sensor, and remove unwanted dirt.
Auto Mode
While running in auto mode, the Coway AP-1512HH will automatically adjust the speed of the device. Auto mode works by collecting data from the air quality sensor and then adjusting the engine speed accordingly.
I used Coway on both auto mode and ECO mode. While I used it in the living room, I liked auto mode more, and Coway did a great job operating in auto mode. However, when I used the Coway air purifier in the study room or in the bedroom, I always used it in ECO mode.
ECO Mode
ECO mode is a fantastic option, and personally, my favorite on the Coway AP-1512HH. If I wanted to simplify the way ECO mode works, then I could say that ECO mode is the same as the auto mode. However, ECO mode has additional functionality that makes it very different from auto mode. Namely, when Coway is switched to ECO mode, the device will monitor air quality all the time via the air quality sensor. If the air quality during the last 30 minutes is excellent, the device will automatically turn off. In that way, it will save electricity, reduce noise, and, of course, save filters.
And that’s not all. The device will stay in stand-y mode, but the air quality sensor will still work, and if the air becomes lousy again, the Coway will turn on automatically and continue the air purification process.
Vital Ion System
I got this info from Coway support: This Coway model features an ionizer. The Ionizer has a switch for on and off. When the LED is illuminated by the button, the Ionizer is on. When the button is not illuminated, it is off. As part of the four-stage filtration process, the bipolar Ionizer produces an electrochemical response that reduces air particles.
I like that the Ionizer is not turned on by default, so anyone can use it as needed. I will explain more information about Ionizer technology in the filtration section.
Timer
A timer is an option that will leave the device running for a certain amount of time and then turn it off automatically. The timer can be set to 1h, 4h, or 8h. This is an excellent option for users who want to run the air purifier for a specific time.
Filter Reset Indicator
This is an option that is standard with almost every air purifier. The filter reset indicator will notify you when it is time to replace the filter. That way, you don’t need to think about a replacement, because Coway does everything for you. My advice is to periodically check the filter for dirt even if the filter reset indicator is not on. This way, you will keep Coway AP-1512HH at maximum performance.
Always pay close attention to which indicator is on to avoid confusion.
Room Coverage and CADR
Coway AP-1512HH is designed for rooms up to 361 sq. ft. It is ideal for rooms where people stay daily, such as the living room, kitchen, or office.
| Dust | 246 |
| Pollen | 240 |
| Smoke | 233 |
Thanks to ECO and auto mode, you can use the Coway AP-1512HH in smaller rooms, and you don’t have to be afraid of wasting electricity. In the table below, I will show you the CADR ratings for the Coway Mighty air purifier.
Coway AP-1512HH Filtration
The Coway AP-1512HH uses 4-stage filtration. The first stage of filtration is the pre-filter, the second stage is the carbon filter, and the third stage of filtration is the true HEPA filter. The fourth stage of filtration is optional, and that is the Ionizer.
Coway AP-1512HH Replacement Filter
Always buy genuine filters for the best performance. As soon as the filter reset indicator is on, you are ready to change filters. Do it as quickly as possible.
Pre-filter
The pre-filter is the first stage of filtration. The primary purpose of the pre-filter is to capture animal fur, large dust particles, and hair.
The pre-filter is washable and should be cleaned on average between 14 and 28 days. This will protect other filters, extend their lives, and make the device more comfortable at work. My recommendation is that if you have pets, clean up the pre-filter regularly and check it as often as possible.
Carbon filter
The carbon filter is not made up of carbon pellets. The carbon filter in the Coway AP-1512HH is a fibrous filter coated with carbon. Carbon filters’ primary purpose is to reduce VOCs, cigarette fumes, harmful gas, pet odors, food odors, and odors.
Coway for odor filtration instead of carbon uses the word deodorization filter. I usually say carbon because I think readers better understand what I mean by that. The name “deodorization filter” may confuse some readers. So let’s call it a carbon filter; after all, that’s what it is.
True HEPA filter
The HEPA filter is the third stage of filtration. True HEPA filter captures 99.97% of airborne allergens, including pollen, mold spores, dust, pet dander, microbes, and smoke. It captures all the particles as small as 0.3 microns in size. A true HEPA filter is not washable, and under no circumstances should it be washed in water.
Ionizer
Coway did not write much information about this technology in the manual or on the online product presentation. I contacted Coway to get as much information as possible about this technology.
Here is what Coway say about Ionizer:
Coway air purifiers have built-in, autonomous ionizers that trap airborne particles and clean the air more efficiently in your home.
When the Ionizer is turned on, voltage is applied to a series of built-in needles, generating electrons that are discharged into the air. When these electrons attach to air molecules, ions are formed.
These negative ions are dispersed into the room where they attach to dust, pollen, cigarette smoke, and pet dander to form more massive particles, which can more easily be trapped by the Coway air purifier. However, these particles can also descend to the floor to be vacuumed later.
How to Replace Coway AP-1512HH Filter?
Coway AP-1512HH filters should be replaced when the filter reset indicators light up. Coway has two indicators to reset the filter. One informs that it is time to replace the HEPA filter, which needs to be changed every 12 months.
The second indicator informs that it is time to replace the carbon filter, which should be changed every 6 months.
Besides, my suggestion is to check every now and then the filter condition and whether the pre-filter is dirty. It is necessary to clean the pre-filter every 2-4 weeks. You can clean it with a vacuum cleaner, with a cloth, or simply wash it.
Total time: 10 minutes.
Turn off the device and after that make sure the power cord is not connected. Then, open the front cover by pulling out the top part of it.
First, pull the pre-filter out, and immediately after that, take all filters out from the Coway air purifier.
Use a vacuum cleaner and clean the inside of the air purifier to remove dust and other particles inside the device.
Prepare new filters, unpack and place them inside the air purifier.
Close up the front panel.
Reset the filter reset indicator by pressing the power button for 2s.
Does Coway AP-1512HH Produce Ozone?
There is not much info online about ozone production, so I asked them again. Here is the answer:
When utilizing the Ionizer feature of select Coway purifiers, they produce a tiny amount of ozone. The 8hr. TWA ozone for Coway products is 0.0011 ppmv when tested in a 30M/3 chamber.
Coway Mighty (AP-1512HH) Ionizer will produce 1 million or 10^6 pcs/cm3 32ft. This product complies with the maximum allowable concentration of ozone of 0.050 parts per million by volume (ppmv) in 24 hours. The Health Canada Guideline 2010 recommends that the maximum exposure limit, based on an averaging time of 8 hours, is 0.020 ppmv or less when tested in a sealed, controlled room approximately 30 m³.
The sticker of the product indicates this product is 0.0011 ppmv, as you found. So this product passed the regulation, and the amount of ozone is much lower than the regulation demands. All of the electrical and electronic products generate a tiny amount of ozone.
Noise Test
The Coway AP-1512HH is extremely quiet at the first speed, so you almost won’t notice it working.
At second speed, it’s a bit louder. While the third speed is too loud, it is difficult to stay in the room while the device is working on the third speed. Fortunately, it turned out to me that the need for a third speed is not very common.
The engine is of good quality. No buzzing or similar irritating sounds are heard. At first speed, the Coway AP-1512HH produces 41.4 dBA of noise. At the second speed, it creates a noise of 44.6 dBA. At the third speed, it makes a noise of 63.5 dBA.
| Speed | Value (dBA) |
|---|---|
| Speed 1 | 41.4 dBA |
| Speed 2 | 44.6 dBA |
| Speed 3 | 63.5 dBA |
I am delighted with the noise levels of the Coway air purifier. Mainly since I tested it in the bedroom for a while. And I didn’t have any problems with the noise at the first speed. If you plan to use Coway in the bedroom, I recommend that you always use it at first speed or possibly in ECO mode. Never leave it running in auto mode while you sleep, as this risks Coway shifting to a higher speed that is much louder and may wake you up.
Performance Tests
Coway AP-1512HH is an air purifier designed for rooms up to 361 sq. ft. I have tested all air purifiers so far in the same way. I measure their performance in a room of specific dimensions for 60 minutes. Apart from these tests, I use the devices every day for a particular period. Based on all this data, I come to the final conclusion.
I mostly advise users to start the air purifier first at the highest speed, hold it for 10-20 minutes, and then switch it to a slower speed. This is not the case with Coway as it offers a host of advanced features that make no need for calculations.
In the tests, I did not use the ECO mode, and I did not use Ionizer. I didn’t use the Ionizer because I don’t practice it very often, and ECO mode because it’s hard to measure performance in that mode and display results.
If the room air quality is continuously low, increase the sensitivity of the air quality sensor, or leave the device running at speed 3 for a while.
320 sq. ft. Room Test
I tested the Coway AP-1512HH in a room of 320 sq. ft. The device was running at third speed all the time for 60min. During that time, Coway lowered the AQI from 148 to 6 and drastically improved the air by 96%. I can say that this is one of the better results I have gotten so far by testing air purifiers. Below you can see a table with a detailed view of all values.
| # | Starting Baseline | After 60min |
|---|---|---|
| PM 2.5 | 113.8 | 4.7 |
| PM 10 | 159.3 | 6.6 |
| Particles | 165036 | 6864 |
| AQI | 148 | 6 |
320 sq. ft. Room Test – Auto Mode
I tested the Coway Mighty again in a 320 sq. ft. room. This time I switched the device to auto mode. Besides, I changed the sensitivity of the air quality sensor to “Standard.” The Coway AP-1512HH improved air quality by about 90% in 60 minutes. The device lowered the AQI from 134 to 13. I am delighted with this result, as well. If I had increased the air quality sensor sensitivity to “Sensitive,” I believe Coway would have made even better results.
| # | Starting Baseline | After 60min |
|---|---|---|
| PM 2.5 | 102.9 | 9.3 |
| PM 10 | 144.1 | 13.1 |
| Particles | 149297 | 13613 |
| AQI | 134 | 13 |
Operating Costs
The Coway AP-1512HH is powered by a 77W motor. The engine power is slightly higher than I expected; however, ECO mode and other accessories contribute to the fact that Coway is not a very big energy consumer.
Suppose you leave Coway Mighty running at third fan speed, 24 hours a day for a period of 30 days. In that case, your electricity bill will be increased by about $ 6. Don’t be fooled by this consumption. In combination with ECO mode and other lower fan speeds, this figure is smaller.
I have already explained that the ECO mode will turn off the device if the air is clean. The device consumes about 1.3W of electricity when in stand-by mode.
Note that the Ionizer will consume an additional 1.2W if turned on. See the table below for detailed power consumption by speed. Another thing to keep in mind is the cost of replacing the filter. The good thing is that the filters are changed every 12 months.
| Speed | Power Usage (W) |
|---|---|
| Speed 1 | 3.6W |
| Speed 2 | 8.1W |
| Speed 3 | 69.1W |
| Stand-by | 0.2W |
Let’s take into account the price of replacement filters, power consumption, and ECO mode. Coway won’t cost you much on an annual basis. Especially when you take into account what you get in return.
The Coway AP-1512HH is a big consumer on paper, but it is several times smaller in practice.

FAQ
Does Coway AP-1512HH produce ozone?
What does Coway Ionizer do?
The Ionizer additionally cleans the air. It uses advanced technology to make small particles bigger and easier to catch.
When should I change Coway AP-1512HH filters?
Is it ok to leave the air purifier over the night?
Yes, there will be no problems if you leave it all night. However, my advice is to use ECO mode, and I think this is a far better option than just letting the device run at some speed.
Is it safe to be in a room with an ionizer feature turned on?
It is. The tiny amount of ozone that this device produces when the Ionizer is on is way under the law limits.
