… Sounds good, but is Coway Mighty air purifier really worth the hype?
In this Coway Mighty air purifier review, we will look at this AP-1512HH model and see how it measures up against the competition.
How Good is Coway Mighty’s Air Filtration System?
The Coway Mighty air purifier is a powerful appliance that can clean a room up to 361 square feet in size. It features a 4-stage filtration system that comprises a Pre-filter, Deodorization Filter, True HEPA Filter, and Vital Ion. And removes 99.97% of airborne particles as small as 0.3 microns in size.
Below are the distinct functions of each filtration state:

Pre-filter: This Pre-filter of the Coway Mighty AP-1512HH is durable and washable. It’s designed to capture large particle pollutants such as pet and human hair, etc.
Deodorization Filter: This activated carbon filter is the next stage in the filtration system, and it traps all forms of gas that are dangerous to health. That way, your home or office is constantly odor-free and safe to breathe.
True HEPA Filter: This third stage of filtration ensures that contaminants like pollen, fungi, allergens, virus, etc., as small as 0.3 microns, are captured and trapped within the purifier. In fact, it captures up to 99.97% of these microns, keeping the air even cleaner.
Vital Ion: This feature can be turned on and off in the air purifier, depending on the user’s needs. However, when turned on, it can improve the air in the room and boost the air purifiers cleaning power.
Air Quality Sensor of Coway Mighty Air Purifier

The Coway Mighty AP-1512HH comes with unique features that set it apart from the competition.
First, it has a built-in air quality sensor that can detect particles as small as 0.3 microns and automatically adjusts the fan speed to match the level of pollution in the room. That way, you are always getting the maximum amount of filtration possible.
As a user, you can adjust its 3-level fan speed manually or choose the auto mode feature, which optimizes the speed settings to suit the condition of the room.
If there’s no pollution or contaminants in the room, the Coway Mighty AP-1512HH conserves energy by switching to eco mode after 30 minutes. It does this automatically and halts the fan speed till it detects new contaminants.
Timer and Filter lifetime Indicator: What You Need to Know.

The Coway Mighty air purifier is designed to have a timer that can run for up to 8 hours before it goes off automatically.
And when you need to know how clean or contaminated your room is, the colored LED on your unit has all the answers. The LED turns blue, purple, and red to indicate good, moderate, and unhealthy air conditions respectively.
The filter life indicator is another useful feature. It notifies you of when the filters need to be replaced, so you don’t have to guess when they need to be changed.
It does this by inspecting your unit’s Pre-filter and HEPA filter, respectively, so that you’ll always know when it needs to be washed or replaced.
This, in turn, helps you get the full lifespan out of the filters.
So far, so good; right? But does the Coway Mighty AP-1512HH live up to its price tag? Let’s take a further look at its other features, pros, and cons before concluding.
Design and Dimension of Coway Mighty Air Purifier
The Coway Mighty AP-1512HH is a tower-style air purifier that measures 9.6 inches in length, 16.8 inches in width, and 18.3 inches in height.
It weighs 12.5 pounds and is available in two dominant color variants; Black and White. Also, it doesn’t require much space and is easy to move around, which is an added advantage.
CADR Rating and Noise Levels: Should You Be Bothered?
Its Clean Air Delivery Rating (CADR) of 233 for smoke, 240 pollen, and 246 dust, in cubic feet per minute(cfm), is higher than most other models. This makes it very effective in cleaning a room of 360 square feet. Also, it is one of the most powerful yet affordable models on the market.
Its low and high noise levels range between 24.4 to 53.8 decibels, respectively, which is just enough to get you to sleep easily. More importantly, since the Coway Mighty air purifier is designed for the bedroom, its lowest noise level doesn’t exceed that of a whisper, while its highest noise level is similar to the whispers of great white noise.
If you’re conversant with most air purifiers, a great white noise is beneficial because it helps people sleep better. Even if you’re a light sleeper, you’ll still find this unit useful.
Price and Value: Is It Too Pricey to Buy a Coway Mighty Air Purifier?

The Coway Mighty air purifier is one of the fairly affordable air purifiers on the market. It retails for around $200 on Amazon as I’m writing.
Pros:
- High CADR rating (the higher the clean air delivery rate, the better its ability to clean indoor air)
