Coway AP-1512HH Air Purifier – Review 2022 (+ Smoke Test)

Specifications Of The Coway AP-1512HH Air Purifier:

Size And Design:

Coway AP-1512HH air purifier is defined by the best-quality craftsmanship. The plastic is of superb quality. Each part lies in its position, and everything is sealed properly. Coway Mighty can be purchased in black or white color. But it’s also possible to combine the color of the frame placed on the front panel. The AP-1512HH model is created in a squared form with round edges. It looks stylish. There’s a carrying handle on the rear right at the top of this unit.

I saw something similar in the Winix C535 and Winix 5500-2 air purifiers. Because of this handle, the Coway AP-1512HH air purifier is simple to carry, and there’s no chance of it just slipping out of hand. Because of the color choice and the elegant look, the Coway AP-1512HH air purifier will really fit into almost any atmosphere.

At the top of the unit is the control panel, with indicators and buttons, which I’ll write more about in the next part. Not just will this machine uplift décor in space, but it’ll also filter the air at a fast speed.

Airflow:

The Coway AP-1512HH air purifier draws air directly from the front and from vents on the bottom, right, and left. Then, the air is filtered through the three basic filters and from the Ionizer if it’s switched on. Clean and filtered air comes out on the upper side of this machine, vertically upwards. When placing the air purifier, make certain that nothing is positioned within twenty-two inches above the device.

Control Panel:

All buttons can be found on the control panel (speed control button, filter reset button, power button, timer button, and ionizer control button). There are indicators above every button. If you put the Coway AP-1512HH air purifier in front of you, all the way to the right on the control panel, right beside the filter reset button, you can see the Air Quality Indicator.

The buttons don’t light. Just the indicators above these buttons are lightened. You will hear a beep sound at each push of a button. What I really loved about the Coway AP-1512HH model are the combos you can actually do with buttons. For instance, you adjust the intensity of the air quality sensor by simply pressing the ionizer and speed buttons for two secs.

Or, if you desire to switch off the Air Quality Indicator, you have to hold the finger on the ionizer button for about three seconds. I’ll explain the intensity of the air quality sensor in more detail in the next section of the Coway AP-1512HH air purifier review.

Dimensions And Size:

The Coway AP-1512 air purifier weighs around 12.34 lb. When compared to the other machines, it’s a little heavier. However, transferring from one location to the other will not be a huge deal, as the transfer handle is handy. The exact dimensions of the unit are 16.81 x 9.56 x 18.30 inches.

What Is In The Box?

When you purchase Coway Airmega, you’ll get 1x True HEPA filter, 1x Warranty Guide, 1x Coway AP-1512HH, 1x User Manual, and 1x Carbon Filter. Personally, I think that the major problem is that just one carbon filter comes with the unit because this filter has to be changed every six months on average. Since the True HEPA filter has to be changed every twelve months, I think it’d be awesome if more than one carbon filter came with this machine.

Features Of The Coway AP-1512 Air Purifier:

Air Quality Sensor:

This type of option is expected from the quality unit, just like the Coway. However, I did not expect its air quality sensor to be this superior and that you can easily adjust the sensor sensitivity. The Coway AP-1512HH air purifier provides the capability of fixing the sensitivity of the sensor at three diverse levels.

The choices you can pick are insensitive, standard, and sensitive. The names themselves say how sensitive it actually is. The sensor will calculate the air quality in the space where the machine is placed. The current air quality will be shown on the Air Quality Indicator located beside the filter reset button.

The Air Quality Indicator can show three diverse colors. When you see that the indicator is blue, it means that the air is of good quality. When you see purple light on the indicator, it means that the air is ordinarily contaminated. When the indicator is red, it means that the air is highly contaminated.

How Can You Adjust The Air Quality Sensor?

By default, the Coway air purifier is actually set to the standard sensitivity. If contamination levels are high after 2 hours of working or if the contamination level is low, but the air quality doesn’t seem really good to you, you can simply adjust the air quality sensor. Follow the below steps for adjusting the air quality sensor:

• First of all, hit the speed button and Ionizer for about 2 secs.
• Then, you’ll hear a beep sound at one-second intervals. The speed indicators will then blink and show you the sensor sensitivity.
• After that, you can set the preferred sensitivity level by simply hitting the speed button. Choose the low sensitivity if the pollution level of the room stays at the highest level for longer than an hour.
• In the end, you have to hold for 2 secs the speed and the ionizer button to resume the regular operation. You can play with it and adjust the sensor’s sensitivity to suit you the best.

How Can You Maintain The Air Quality Sensor?

The air quality sensor ought to be cleaned every two months. The cleaning procedure is simple. Open the sensor cover that can be found on the side. Utilizing the ear cleaning brush, clean all sensor components, and get rid of undesired dirt.

Auto Mode:

The Coway AP-1512HH air purifier, while running in the auto mode, will adjust the unit’s speed automatically. The auto mode functions by collecting information from the air quality sensor and then simply adjusting its fan speed accordingly.

I utilized Coway in both ECO mode and auto mode. While I utilized it in the living space, I loved the auto mode more, and Coway did an awesome job operating in the auto mode. However, when I utilized the Coway air purifier in the bedroom or in the study room, I always utilized it in the ECO mode.

ECO Mode:

ECO mode is an incredible option, and personally, it is a favorite on the Coway AP-1512HH air purifier. If I desired to simplify the manner ECO mode works, then I can say that ECO mode is just the same as the auto mode. However, ECO mode has added functionality that makes it extremely diverse from the auto mode. Namely, when the Coway air purifier is switched to ECO mode, the machine will check the air quality all the time through the air quality sensor.

If the air quality throughout the last thirty minutes is exceptional, the unit will automatically switch off. In this manner, it’ll decrease noise, save electricity, and, certainly, save filters. And that is not all.

The machine will stay in the stand-y mode, but the air quality sensor will still function, and if the air becomes terrible again, the Coway air purifier will switch on automatically and continue the air purification procedure.

Timer:

A timer is a choice that’ll leave the machine running for a certain time and then switch it off automatically. The timer can be set to 1 hour, 4 hours, or 8 hours. It’s an outstanding option for those who desire to run their air purifier for a particular time.

Vital Ion System:

I got this information from the Coway support department: This Coway model comes with an ionizer. The Ionizer has a switch for turning it on/off. When the LED is lit up using the button, the Ionizer is on. When the button isn’t illuminated, it’s off.

As part of the 4-stage filtration procedure, the bipolar Ionizer creates an electrochemical response that decreases the air particles. I love that the Ionizer isn’t switched on by default, so anybody can make use of it as required. I’ll explain more details about Ionizer technology in the filtration part.

Filter Reset Indicator:

It’s an option that’s standard with almost each air purifier. The filter reset indicator will tell you when it’s time to replace its filter. That way, you do not have to think about the replacement because Coway does it all for you. My advice is to check its filter for dirt periodically, even if the filter reset indicator isn’t on. Like this, you’ll keep the Coway AP-1512HH air purifier at max performance. Always pay attention to which indicator is on to avoid confusion.

CADR And Room Coverage:

Coway AP-1512HH air purifier is created for spaces up to 361 square feet. It’s perfect for spaces where users stay daily, like the kitchen, living room, or office.

• Dust: 246
• Smoke: 233
• Pollen: 240

Thanks to the auto and ECO mode, you can make use of the Coway AP-1512HH air purifier in the smaller spaces, and you do not need to be afraid of wasting electricity.

Coway AP-1512HH Filtration:

The Coway AP-1512HH air purifier makes use of a four-stage filtration process. The 1st stage of filtration is the pre-filter, the 2nd one is the carbon filter, and the 3rd filtration stage is the true HEPA filter. The 4th filtration stage is optional, and that’s the Ionizer.

Pre-Filter:

The pre-filter is the 1st filtration stage. The main purpose of this pre-filter is to actually trap hair, large dust particles, and animal fur. The pre-filter is washable and ought to be cleaned on average between fourteen and twenty-eight days.

It’ll protect other filters, extend their lifespan, and make your machine more comfortable at work. My suggestion is that if you have pets, clean up its pre-filter frequently and check it as frequently as possible.

Carbon Filter:

This filter isn’t actually made up of carbon pellets. The carbon filter in the Coway AP-1512HH air purifier is a fibrous filter coated with carbon. The primary purpose of the Carbon filter is to decrease food odors, cigarette fumes, VOCs, pet odors, harmful gas, and odors.

Coway for smell filtration instead of carbon makes use of the word deodorization filter. I frequently say carbon because I think readers better comprehend what I denote by that. The name deodorization filter might confuse a few people. So let’s call it the carbon filter; after all, that is what it really is.

True HEPA Filter:

The HEPA filter is actually the 3rd stage of filtration. The True HEPA filter traps 99.97 percent of the airborne allergens, including mold spores, pollen, pet dander, dust, smoke, and microbes. It traps all the particles as little as 0.3 microns in size. The true HEPA filter isn’t washable, and under no conditions should it be cleaned in water. Ionizer:

Coway didn’t write many details about this technology in the online product presentation or in the user manual. I contacted the brand to get as much data as possible about this technology. Here’s what they say about ionizers: Coway air purifiers have integrated, autonomous ionizers that capture airborne particles and purify the air more efficiently in the house.

When the Ionizer is switched on, voltage is applied to a series of integrated needles, producing electrons that are released into the air. When such electrons attach to the air molecules, ions are created. Such negative ions are dispersed into the space where they attach to pollen, dust, pet dander, and cigarette smoke to form more massive particles, which can more simply be trapped by the Coway air purifier. However, such particles can also fall to the floor to be vacuumed afterward.

How Can You Replace Coway AP-1512HH Filter?

Coway AP-1512HH filters ought to be replaced when their filter reset indicators illuminate. Coway has two indicators for resetting the filter. One notifies that it’s now time to replace its HEPA filter, which has to be changed every twelve months.

The 2nd one notifies us that it’s now time to replace its carbon filter, which ought to be changed every six months. Besides, my recommendation is to check the filter condition from time to time and whether its pre-filter is filthy. It’s essential to clean the pre-filter every two to four weeks. You can clean it using the vacuum cleaner, using a cloth, or simply wash it.

Total time: 10 minutes.

• First of all, switch off the machine and after that make certain the power cable isn’t connected. Then, open its front cover by simply pulling out the top section of it.
• Now, pull its pre-filter out, and right after that, remove all filters from the Coway air purifier.
• After that, make use of the vacuum cleaner and clean the air purifier’s inside to get rid of dust and other particles inside the unit.
• Next, prepare the new filters; simply unpack and put them inside the air purifier.
• Close up its front panel.
• Then, reset the filter reset indicator by simply hitting the power button for about two seconds.

Does Coway AP-1512HH Air Purifier Produce Ozone?

There are not many details online about ozone production, so I asked Coway again. Here’s the answer: When using the Ionizer feature of some Coway purifiers, they generate a little amount of ozone.

The 8 hours. TWA ozone for Coway devices is 0.0011 ppmv when tested in the 30M/3 chamber. Coway AP-1512HH Mighty Ionizer will generate one million or 10^6 pcs/cm3 32 feet. This device complies with the max permissible concentration of ozone of 0.050 parts for each million by volume (ppmv) in twenty-four hours. The Health Canada Guideline 2010 suggests that the max exposure limit, based on the averaging time of eight hours, is 0.020 ppmv or less when tested in a controlled, sealed space of approximately 30m³.

The device’s sticker specifies this device is 0.0011 ppmv, as you found. So this machine passed the regulation, and the ozone amount is much lower than the regulation demands. All of the electronic and electrical products produce a small amount of ozone.

Noise Test:

The Coway AP-1512HH air purifier is very quiet at the first speed, so you almost would not notice it functioning. At 2nd speed, it is a little louder. While the 3rd speed is very loud, it’s hard to stay in space while the machine is functioning on the 3rd speed. Luckily, it turned out to me that the requirement for the 3rd speed isn’t very common.

The motor of the device is of good quality. No buzzing or similar frustrating sounds are heard. At 1st speed, the Coway AP-1512HH air purifier makes 41.4 dBA of noise. At the 2nd speed, it makes a noise of 44.6 dBA. At the 3rd speed, it creates a noise of 63.5 dBA.

I’m pleased with the noise levels of the Coway air purifier, mostly since I tested it in the bedroom for a time. And I did not have any issues with the noise at the 1st speed. If you want to make use of your Coway air purifier in the bedroom, I suggest that you always make use of it at 1st speed or possibly in the ECO mode. Never leave it working in the auto mode while you sleep, as it risks Coway shifting to a higher speed that’s much louder and might wake you up.

The Performance Tests:

Coway AP-1512HH air purifier is a device created for spaces up to 361 square feet. I’ve tested all the air purifiers so far in the same manner. I calculate their performance in the space of particular dimensions for sixty minutes. Apart from such tests, I make use of the machines daily for a particular time.

Based on all this information, I came to the final verdict. I frequently advise users to start the air purifier at the highest speed, hold it for ten to twenty minutes, and then switch it to the slower speed. It’s not the situation with the Coway air purifier, as it provides a host of advanced features that make no need for computations. In the tests, I didn’t make use of the ECO mode, and I didn’t make use of Ionizer.

I did not make use of the Ionizer because I do not practice it very frequently and the ECO mode because it is difficult to calculate performance in that mode and show results. If the air quality of the room is continuously low, boost the air quality sensor’s sensitivity, or leave the machine running at speed three for a while.

320 Square Feet Room Test:

I tested the Coway AP-1512HH air purifier in the space of 320 square feet. The unit was working at 3rd speed all the time for sixty minutes. Throughout that time, Coway lowered its AQI from 148 to six and drastically improved the air by ninety-six percent. I can say that it’s one of the better outcomes I’ve received so far from testing air purifiers. You can see a table with the full view of all the values down here.

320 Square Feet Room Test (Auto Mode):

I tested the Coway Mighty air purifier again in a 320 square feet space. This time I turned the unit to auto mode. Besides, I changed the air quality sensor’s sensitivity to Standard. The Coway AP-1512HH air purifier improved the air quality by about ninety percent in sixty minutes.

The machine lowered the AQI from 134 to 13. I’m pleased with this outcome, as well. If I had increased the sensitivity of the air quality sensor to Sensitive, I believe the Coway air purifier would’ve made even better outcomes.

Operating Charges:

The Coway AP-1512HH air purifier is powered by a 77W motor. The motor power is a little higher than I actually expected; however, the ECO mode and other accessories add to the fact that the Coway air purifier isn’t an extremely large energy consumer. Suppose you leave your Coway Mighty air purifier running at 3rd fan speed, twenty-four hours a day for a period of thirty days.

In that situation, the electricity bill will be increased by about six dollars. Do not be fooled by this use. Together with the ECO mode and other lower fan speeds, this number is smaller. I’ve already clarified that the ECO mode will switch off your device if the air is clean.

When in the standby mode, the machines use about 1.3W of electricity; note that the Ionizer will use an added 1.2W of energy if switched on. See the below table for thorough power consumption by speed. Another thing to remember is the price of replacing the filter. The great thing is that the filters are changed every twelve months.

Let’s consider the cost of power consumption, replacement filters, and the ECO mode. Coway would not charge you much on an annual basis, particularly when you consider what you get in return. The Coway AP-1512HH air purifier is a big consumer on paper, but it’s actually numerous times smaller in practice.

Coway Customer Service And Warranty:

Coway provides a three-year limited warranty for this particular model. To register, you have to visit the Coway Mega website and enter the purchase details. I contacted the Coway support service via Facebook and Email. I waited a bit longer for the answer through Facebook. However, I received an efficient, quick, and pervasive response through Email. Email support is extremely helpful, and they are prepared to explain any ambiguity in-depth and resolve any issue together.

Conclusion:

As I mentioned at the start of this review, the Coway Airmega AP-1512HH air purifier is one of the machines I’ve always desired to test. My experience with Coway has lived up to all my expectations. It’s even a bit above expectation in a few parts. The Coway AP-1512HH air purifier did awesome on all tests, particularly when it comes to the performance.

I think this unit is perfect for the office, bedroom, living room, or even basement. The warranty for the Coway AP-1512HH air purifier is three years. Support is helpful and fast. Because of all the above, the Coway AP-1512HH air purifier is my ultimate recommendation to purchase.
