Review of the Coway AP 1512HH Mighty Air Purifier True HEPA Filter

I chose to review the Coway AP 1512HH Mighty Air Purifier because of its ability to clean the air with its impressive 4 stage filtering system and its iPod like styling. The Coway company has a great reputation for building quality products, including its air purifiers.

I have just finished my Spring cleaningand I’m looking for a solution to keep the dust and allergens out of my home. The Coway AP 1512HH Mighty Air Purifier is the best HEPA filter air purifier in its size and price category.

The Coway AP 1512HH Mighty Air Purifier appears to have everything I would want in an air purifier. There’s a pre-filter that is washable, a carbon filter, a True HEPA filter and an ionizer.

I like that it is equipped with sensors that will monitor the air quality with an indicator light that tells you when you need to clean the HEPA filter; I also like that it has an economy mode and also a timer that lets you set it for 1, 4 or 8 hours.

Let’s look at what makes the Coway AP 1512HH Mighty Air Purifier a good buy.


Hmm … the best thing that comes to mind to describe this air purifier is that the Coway air purifier kind of looks like a giant IPOD – without the music of course. LOL

In my opinion, this air purifier actually has quite a cool modern design. I like this look and think it looks quite impressive. I’m drawn to the white as it should blend in nicely with just about any decor, in any of the rooms, in your home.

It comes in two colors – white or black and it has a sleek looking outer casing with rounded edges. The dimensions are 16.8’’ x 18.3’’ x 9.6’’ and the Coway air purifier only weighs about 13 pounds making it easy to move from room to room if you so desire.

The compact size of the Coway air purifier allows for you to place it just about anywhere in your home even behind your furniture.

I like that the control buttons are located in a panel on the top of the unit. In the control panel, there is a light that tells you how dirty the air is. The console has 3 lights;

  • blue – the air is clean
  • purple – the air is moderately dirty
  • red – the air is really dirty.

The Coway Mighty Air Purifier also has a timer. The timer can be set for 1, 4, or 8 hours. This works well if you only want to run your air purifier while you are at work or asleep.

(This is also a great feature if you want to clean just one area of your house. For example if you have a fishy smell in your kitchen from dinner, you just plug in the Coway and let it work for about an hour and your kitchen is now clean and fresh).

Another feature that The Coway Air Purifier has is its ability to take air in from the front and the bottom of the unit. Then the clean air is released out the top of the unit.

I like this feature because it allows you to place it anywhere in your room as long as you don’t put anything directly in from of it.

A bonus with the air going out the top of the unit is that it won’t be blowing directly on anyone or anything in your room!

What’s on the inside?


The Coway AP 1512HH Mighty Air Purifier comes with a 4-stage filtration system that claims to remove air contaminants and odors.

Stage 1 – Pre-Filter – is a permanent filter that was designed to capture large particles. Things like hair, fur, and larger dust particles. It is meant to collect the bulk of the material being pulled into the purifier. It will extend the lifespan of the other filters if you keep it clean. Cleaning should be done every 2 to 4 weeks depending on how often or how long it is used.

Stage 2 – Activated Carbon Filter – smaller particles, gases and odors can be blocked at this stage. This filter should be changed about every 6 months. Cost to replace the filter is about $5 a filter (March 2019) – About the price of a Starbucks Latte.

Stage 3 – True HEPA Filter – The Conway air a purifier comes with a certified True HEPA filter that claims to clean up to 99.7% of contaminants in your air up to 0.3 microns in size. This filter needs to be changed yearly and will set you back about $40 (This was the price as of March 2019)

Stage 4 – Vital ionizer – This is the final stage of the filter system. The Vital ionizer “generates an electrochemical reaction reduces particles in the air”.

Note: There is some controversy over ionizing your air. If you are concerned or have reservations with this feature there is an option to turn it off.



The Coway AP 1512HH Mighty Air Purifier has a control panel that is located on the top of the unit. It controls the various sensors that make the air purifier user-friendly.

Air Quality Sensor – With the quality installed air sensor you don’t have to guess at whether the purifier is working. The sensors will automatically decrease or increase the fan speed to keep the air in your home clean.

Eco mode – This is basically an energy saving mode. Once the air quality is normal for more than 30 minutes the Eco mode kicks in. This turns your fan off.

Timer – Set it and forget it! The timer can be set for 1, 4, or 8 hours.

Filter replacement indicator – The filter indicator is for your True HEPA filter. It does not control the carbon filter or your opinion, this – wash filter.


Most people are often concerned about the noise level when they are looking to purchase an air purifier. Often this can even be a deal breaker.

The manufacturer of the Conway Mighty Air Purifier claims that the noise level of this model doesn’t exceed 58 decibels. This means that even at the highest fan speed it will not be any louder than a normal conversation.

Most reviewers say that the first and second fan settings are the quietest. They do say that the third fan setting is a bit louder.

Referred to as the ‘mighty air purifier but is reported to be very quiet in the low setting


  • A few people found it loud on the high setting which is pretty typical of most air purifiers.
  • Several people wished it was bigger; one reviewer purchased a second one so that it would filter her whole apartment


I definitely would buy the ‘Mighty’ Coway air purifier. I love the modern iPod styling and think it would look great in just about any decor. The four stage filter system has a HEPA filter which I think is one of the best filters to look for if you want an air purifier.

It also has sensors that will make the operation easy. I love it’s compact size making it easy to move from room to room.

The Coway Mighty Air Purifier is an excellent option for an air purifier in its size and price group. I like that the company has a good reputation and that the Conway get great reviews on Amazon and the Conway’s website.

I like that the Coway AP 1512HH Mighty Air Purifier has a low up-front cost; that the maintenance is minimal; and the electricity costs make it among the cheapest to own in its category.

It gives you great value for your money and it the perfect solution for cleaning the air in your home with the best HEPA available on the market in this price range.
