Today, we’re taking a look at three air purifiers, each one is from Coway. We’ll be taking a look at the Coway AP-0512NH, the Coway AP-1216L, and the Coway AP-1512HH.

All three of these air purifiers are quite good, and they each have their own excellent features and attributes that make the air purification process simple and efficient.

In this article, you’re going to learn all about these three air purifiers. You’ll learn about their features, their attributes, the advantages those features and attributes give you, and, finally, which air purifier is the right air purifier for you.

Now, let’s begin with the Coway AP-0512NH!

Coway AP-0512NH

With the Coway AP-0512NH, you can cover a space that is up to 155 square feet. For an air purifier, this really isn’t that much, unfortunately. However, it has been designed to thoroughly purify those kinds of spaces. But, considering the price that you are paying, it does seem a bit too small.

There are four individual filters that are used. The first is a basic Pre-Filter, which is designed to remove all of the larger particles and matter so that it doesn’t affect the other filtration stages. Then, there is an Odor Filter, which takes in the particles that are emitting nasty odors, and destroys them. After that, you have a standard True-HEPA filter. With the True-HEPA filter, you can remove allergens and other contaminants that are as small as 0.3 microns – that’s 300-times the size of a single strand of hair. Finally, the last filtration stage is a Bipolar Ionizer, which uses ions to eradicate any remaining pollutants, as well as any airborne odors.

The other aspect of the Coway AP-0512NH is the fact that it doubles as a “white noise machine”, and has been developed with the help of doctors and therapists. So, while your air is being purified, you can relax, due to the white noise that is created by the purifier, which serves as a kind of sound therapy.

Other than that, though, this is a pretty basic air purifier/sound therapy machine, and due to the cost, it may not be the best purchase, simply because it doesn’t offer much, and it’s really expensive.

Coway AP-1216L

Let’s start off with one of the most notable differences that the Coway AP-1216L presents. Unlike the Coway AP-0512NH, the Coway AP-1216L can cover a total of 330 square feet. It has been designed to cover more mid-range spaces, rather than smaller and tighter spaces.

The Coway AP-1216L also doesn’t have a white noise feature.

At any time, you can take a look at the small indicator, near the top of the device, and it will tell you the quality of your air. If you want, you can turn on “Auto Mode” which uses that information to adjust the settings to best accommodate the quality of your air, at that time. Naturally, this makes the air purification process much easier, since you don’t actually have to do anything, with regards to the setup. Instead, the device will choose which one of the three fan speeds is ideal.

Another fantastic feature that makes the air purification process easy and relatively hands-off is the “Timer” feature. Using the Timer, you can tell the air purifier to run for 1-hour, 4-hours, 8-hours, or 12-hours, depending on your needs.

When it comes to the filtration process, it’s pretty much exactly the same as the filtration process found in the Coway AP-0512NH. You have the Pre-Filter, for removing the larger particles, and then the Odor Filter, for eliminating bad smells, and then after that you have the True-HEPA filter, which removes the small allergens, germs, and pollutants. Finally, there is the Bipolar Ionizer, which kills off the remaining particles.

This filtration process is very thorough and effective, so it didn’t need to be changed or altered.

Coway AP-1512HH

Finally, we have the Coway AP-1512HH. This is the most advanced, and most expensive, air purifier on this list.

To start off, using the Coway AP-1512HH, you can purify a space that is up to 361 square feet. Now, again, this isn’t really that much space, but it is a decent amount, and for a living room, it should work just fine. Anything bigger than that and it may have some issues.

When using the air purifier, there are three distinct fan speeds that you can choose from.

– Low
– Medium
– High

But, if you use “Auto Mode” the air purifier will choose the right setting for you, by using its sensors to detect the quality of your air. Having a mode like this is very useful, and it makes the entire experience of using this air purifier much more “hands-off” since you can let the air purifier do what it needs to do.

This same philosophy has been applied to the “Timer” feature, which works in the same way. Choose how long you want the air purifier to run for, and then once that time is up, the air purifier will turn off, so that it doesn’t use more electricity than it needs to.

Just like the previous two air purifiers, this one uses the same basic filtration system. You have the Pre-Filter, the Odor Filter, the True-HEPA filter, and the Bipolar Ionizer.

Overall, there really isn’t that many differences between this air purifier and the ones that have come before it. Each one is quite good and effective. But, the main flaw is that they don’t cover that much space. And since they are so expensive, this can be a bit annoying.

Coway AP-1512HH Air Purifier


At the end of the day, these are well-made air purifiers that are very good at purifying your air and getting rid of all of the nasty particles that are in your air. But, with that being said, these air purifiers are also quite expensive, and considering the relatively low MAC – Maximum Area Coverage – they may not be the ideal purchase for you, unless you want to purify a smaller space and you don’t mind spending some extra cash.
