Our verdict:

Coway has proven itself time and again to be at the forefront of air purifier development. The Airmega AP-1512HH Mmighty is a little old now, but it still stands tall when compared to some of the more current units out there.

It has all the smart features you come to expect from air purifiers like auto and eco fan modes, a timer, an air quality monitor with an indicator, and it houses a high-powered motor that makes sure the fan works hard in your room, but this does mean it uses a lot of power.

It does look like it’s come straight out of Darth Vader’s bedroom, but that’s up to you whether that’s a pro or a con, but I like it. 

I’ll be honest; this isn’t the best unit we’ve reviewed, nor is it the worst. It’s hard-working and does its job well; if you’re looking at the AP-1512HH Mighty, be aware that its reported CADR is based on it using an ionizer combined with a HEPA filter.

Coway has been at this game since 1989, developing products closely with their team of engineers and designers, which have won them many awards over 30 years. Coway has always been at the forefront of innovation, mixing the core needs of an air purifier with luxury features built-in.

“Combining efficiency and modern design, we’re helping the world breathe clean air, drink pure water, and elevate their hygiene.” 

Along with Levoit and Honeywell, Coway is one of the biggest brands on the market, and with new models like the Airmega IconS alongside favorites like the Airmega 300, you know you’re getting a high-performing, durable unit.

If you’ve read any of our air purifier reviews before, you’ll know that we don’t pull any punches. We buy each unit with our money and have no ties to any brands. This means we give you our unbiased views and opinions with no bull.

TL;DR The Low Down on the Unit

We know that your time is precious so here’s our Too Long; Didn’t Read pros and cons about the AP-1512HH Mighty air purifier.

What We Really Like:

👍 Good cost per CADR – 62 cents per CFM
👍 Has a color-coded air quality monitor
👍 It has a carry handle for easy transportation
👍 Looks good and modern compared to many beige units

What We Think Could Be Better:

👎 Not totally sold on the idea of an ionizer but you can switch it off
👎 You can get better performance for less money with Taotronics AP-003
👎 I’d like to see a numerical display instead of just color ratings

The Specifications

At $229.99 the AP-1512HH Mighty is at the lower end of the budget spectrum which is pretty standard for a unit with a CADR of 240 CFM, unless you look at the Levoit 600S which has a 400 CFM for an extra $70. It is designed to tackle contaminants in rooms around 361 sq. ft which aren’t huge but with that CFM it should clear rooms pretty fast (keep reading to see our performance test results).

Alexa, Play the Imperial March

In my humble opinion, this unit looks really cool from the front. Coway have never been scared to think outside the box when it comes to design and this is no different. Maybe it’s because I like black units, or maybe it’s because I’m a fan of the dark side of the force, but the gloss finish and round styling make this air purifier look appealing to me.

There’s no visible grill on the front like you see with other air purifiers, instead, there’s a glossy sphere which, when you look into it, is like looking into the bottom of a spoon. The control panel sits on top for easy access with the grill, meaning you can put this unit back against the wall, and it won’t affect the airflow.

If I ruled the world –  The round white circle surrounding the bubble gives the front of this unit a sleek look, but I’d love it if it was used as the color air quality indicator.

I sat the AP-1512HH next to our Winix 5300-2 to see how it looked compared to a unit with similar specifications. In my opinion, the Coway would fit better into a modern home with its glossy finish and rounded corners. It doesn’t look like a conventional air purifier which is one of the things I love about this unit.

Powerful 4-Stage Filtration

When looking for an air purifier for your home, we recommend you only look at units that use HEPA filters as they are scientifically proven to be the most efficient method of removing airborne contaminants from your home. The AP-1512HH houses a True HEPA filter that traps 99.97% of tiny harmful particles like dust, pollen, mold, and smoke.

The HEPA filter may be the most important of the four stages, but it wouldn’t be able to work as efficiently without the other pre-filter and activated carbon filters.

  • Pre-filter – This acts as the first line of defense against airborne contaminants. It works by trapping larger pollutants in its material, thus, prolonging the life of your HEPA. This pre-filter can also be cleaned, so you won’t need to replace it when dirty.
  • Activated carbon – Coway refer to this as their Deodorization filter which is basically what it does. This sheet of bonded carbon uses a process called adsorbtion to trap odors and other VOCs removing them from the air in your room.

You may have noticed it says “4-stage filtration” in the title, and I’ve only mentioned three. This is because the fourth is an Ionizer. For those unfamiliar with this technology, it basically means the air purifier creates an electrochemical reaction in the air which attracts additional airborne pollutants. The reason I didn’t initially include the ionizer is because I’m not convinced how effective the technology is, but it’s there if you want it.

As with most air purifiers, when the filters become full of pollutants, they start to become less effective, that’s why you need to change them after a period of time. The HEPA and activated carbon filters need changing around every six months but don’t worry about adding it to your calendar, the Airmega will indicate when they need replacing. 

Replacing the filters is essential and easy to do. 

  • Step 1: Remove the front panel by pulling it away from the body
  • Step 2: Unclip the pre-filter from the top and put to one side
  • Step 3: Take out the activated carbon filter
  • Step 4: Pull on the tabs to remove the HEPA filter
  • Step 5: Replace the filters and reassemble your unit 

Do me one favor, make sure you’ve removed all the plastic packaging from the replacement filters before installing them into your air purifier. If you don’t then the filters won’t work, and you’ll probably smell a plastic burning smell after a while. Not what you want, I assure you. 

5 Buttons for Easy Control

There’s nothing worse than getting a new product and having no clue how to work it. Luckily, Coway have always had the customers in mind when it comes to operating their air purifiers and the AP-1512HH is no different.

Its simple five-button operation is nicely spaced apart, so you’re not pressing the wrong one accidentally. They are physical buttons (not touch sensitive which is subjective to what you personally like), they don’t stick, and they have symbols on, so there’s no confusion. 

On/Off – Pretty self-explanatory 
Fan Speed – This will allow you to change through the three fan speeds and also select eco and auto modes. Eco Mode turns the fan speed to its lowest to save energy. If your environment is clean after 30 mins, it will turn the fan off.
Auto mode works using the unit’s in-built air quality monitor and adjusts the fan speed according to its readings. If the air is bad, it will turn the fan up without you needing to press any buttons.
Ionizer – This button engages the ionizer function if you wish to use it. To turn it off, simply press the button again.
Timer – Select from 1hr, 4hr, and 8hr countdowns. After the time selected has depleted the air purifier will automatically turn off.
Filter Reset – (The least exciting button on the unit). When your filters need replacing, an indicator light will show up on the control panel. Once you’ve replaced the filter(s) hit this button, so the unit knows it has fresh ones installed.

At the end of the control panel is the air quality indicator. This shows you how clean the air in your room is in real-time. It will show you one of three colors; red indicates that your air is heavily polluted, purple shows the room is medium polluted, and blue indicates your air is currently clean. Very intuitive. 

Cleared Our Room in 23 Minutes 

Okay, here’s the science and probably the reason you’re looking into this air purifier in the first place, its performance. Unlike some other air purifier review sites, we don’t rely on the manufacturer’s performance testing results because they most likely conducted those tests in a lab environment. You probably don’t have a lab, and neither do we, so we do our own tests in our 705 cubic ft office.

Here comes the fun part… We first fill our room full of pollution to simulate the worst-case scenario using a concentration of incense smoke. Once the room is fully contaminated, we switched the Coway onto its highest fan speed and measured how long it took for the unit to clear the room of the pollutants.

We measured our results using an indoor sensor from Purpleair, which provides us with constant updates on PM1.0ug/m3, PM2.5ug/m3, and PM10.0ug/m3 (pollution).

Here is what we found.

As you can see from the results graph, the AP-1512HH cleared our room of contaminants in 23 minutes. This shows that its high-performance fan makes light work of heavy pollution. This just goes to show that the years Coway has been making units has provided them with the technology and know-how to manufacture air purifiers that are highly efficient.

If we compare this to other units we’ve tested, you’ll see just how well the AP-1512HH performed.

Air PurifierHow long it took to clean the airCADRPrice
Coway Airmega AP-1512HH23 minutes240 CFM$229.99
Winix 5300-227 minutes246 CFM$213.99

Conway Airmega 30026 minutes300 CFM$549
Levoit Core 400S33 minutes260 CFM$219.99

Another pro of this air purifier is the sound it makes. It can go from 24 dB (lowest fan speed) to 53 dB (high fan speed) which, for air purifiers, is right down the middle average. Have a listen for yourself.

The AP-1512HH Could Cost Up To $226.05 a Year To Run 

1. Electricity costs

When you buy an air purifier, as with any electrical product, the cost doesn’t end with the initial purchase, you need to power it and that costs money. With the ever-growing energy prices, this is something that you can’t take lightly. Luckily, many air purifier manufacturers are doing their best to make their units as energy efficient as possible.

We clocked the AP-1512HH taking 77.6 watts of electricity on full power which is on the higher side for a unit of this side but not crazy high. When we compare that to similar air purifiers; we measured the Winix 5300-2 at 63.4 watts, the Conway Airmega 300 at 52.5 watts, and the Honeywell’s HPA300 at 87 watts.

To work out how much the AP-1512HH could cost you per year we used our Air Purifier Usage Calculator. This uses the average cost of energy in each state, and calculates how much it will cost you to run your unit based on the wattage it pulls.

If you ran this unit at full speed (77.6 watts), it would cost you a total of $168.58 a year in California. But, as you’ve seen from the performance test, you shouldn’t need to run the Airmega on full for that long so this calculation is at the top end.

See what it could cost in your state using our Air Purifier Usage Calculator.

2. Filter costs

As I mentioned earlier, filters don’t last forever. As they fill up with all the contaminants they’ve trapped from the air in your room, they become less and less effective. Different filters have different life spans, for the AP-1512HH, that life span is 6 months.

This is an important cost to factor in, if you don’t replace filters when they need to be replaced, you might as well not turn your air purifier on in the first place. At least you know that it’s very simple to do when the time comes. 

Coway offer a pack where you can buy both HEPA and two activated carbon filters together saving you time and money in making several purchases. This pack retails at $57.49 from their site, but there are always deals on Amazon.

Bottom Line

Although Coway’s Airmega line has advanced quite a bit since the release of the AP-1512HH (check out the Airmega IconS) but this unit still holds up when it comes to the most important job for an air purifier…how efficiently it cleans the air. 

It’s a cool design that comes in both black and white. It doesn’t look like an air purifier, but looks like something from outta space! Not only does it look great, but it’s easy to use. The control panel is well-labeled, and the buttons are far enough apart to not get confusing.

The issue with this unit is that technology dates so fast. As this is now a few years old it doesn’t contain all the smart features the new units offer like smartphone app control or numerical air quality indicator. I’m also not a big fan of the bonded activated carbon sheets, I believe the loose fill filters do a much better job and last a whole lot longer.

Compared to similar units the AP-1512HH is a great performer. It cleared our testing room rapidly and hasn’t stopped giving us great results since we bought it. If you’re looking for a workhorse of a unit that looks different from the rest, then this would make a great addition to your home. 


The Rules We Followed When Reviewing the Coway Airmega AP-1512HH

With every review we do here at HouseFresh, we want to give you a clear understanding of which air purifiers are worth investing in and which aren’t worth your hard-earned dollars.

That’s why:

1. We bought the AP-1512HH with our own money and performed our own performance testing in our own home.

2. We read the manufacturers’ feature lists and specification figures, but we don’t rely on them. By testing the performance of this unit in real-world conditions with our testing tools, we can give you reliable, unbiased information.

3. We used the data from our performance test to compare the AP-1512HH with other similar air purifiers in the market to get a like-for-like comparison to help you pick the suitable unit for your needs.

4. We don’t just stop there. To ensure the AP-1512HH lasts long term we evaluated the benefits and downsides of using the AP-1512HH by putting the unit to the test for over 8 months.

Our Testing Process 

At the end of the day, we are consumers, too, so we always research CADR rankings and other performance metrics published by the manufacturers before we get our hands on a unit. 

We wouldn’t recommend a unit without being 100% confident we make the right call. This is why we always test air purifiers ourselves. 

That’s why we test all our units in the same room (sized 705 cubic ft) performing the same job (removing incense smoke), which allows us to make side-by-side comparisons.

We use the PurpleAir PA-I Indoor PM 2.5 Sensor that combines the ability to track PM1.0ug/m3, PM2.5ug/m3, and PM10.0ug/m3 every few minutes. We then use Flourish to visualize this data to help us determine how long it took this specific unit to remove all contaminants from the air.

SOURCES

We calculated the monthly energy consumption costs with the help of our air purifier electricity usage calculator. We calculated daily and yearly costs associated with running an air purifier for 24hs a day in California. You can customize the result by air purifier wattage and by state.
