HEPA technology is one of the best performing filtration techniques used by air cleaning devices. The Coway AP-1512HH home air cleaner uses the true HEPA filtration technique to purify the air that goes through it.

We’ve researched the latest air purifiers, asked the experts, and sifted through thousands of specs, features and user reviews to find the best air purifiers. Here’s everything you need to know about the Coway AP-1512HH Mighty Air Purifier.


This very reliable filtration mechanism eliminates up to 99.97% of airborne pollutants. With this air purifier at home, you can be certain that the air in any room is free from dust, pollen, mold spores, pet dander, and much more.

The AP-1512HH has an air sensing system that identifies the levels of air pollution. If the system operates for thirty minutes without discovering airborne pollutants, it immediately puts a stop to the fan to save power. This smart technology makes sure that the air in any room is clean and fresh and it is also good for your wallet.

Air purifiers that are certified through AHAM’s Certification Program have been certified and verified by an independent laboratory, ensuring buyers that the air purifier will work based on the manufacturer’s item claims for recommended room size and the minimization of 3 typical household particulates: tobacco smoke, dust, and pollen, commonly referred to as the Clean Air Delivery Rate (CADR).

Coway AP-1512HH Mighty Air Purifier Review

Coway AP-1512HH Filter

The Coway AP-1512HH Mighty Air Purifier with True HEPA and Eco Mode has 3 filters and a negative ionizer.

1. Pre-filter

The washable and/or vacuumable permanent fiberglass screen pre-filter, no longer a granted feature in today’s price-sensitive air cleaner market, does a great job in capturing larger dust particles before the other filters come into place. The first filter is a huge advantage for this air purifier.

Many brands have removed this pre-filter to reduce costs, but Coway has kept it unchanged. This filter is reliable aimed towards the largest particles like dust and pet hair. Furthermore, this filter extends the life of the other filters inside the machine by stopping them from being clogged by larger particles. Last but not least, this filter is also washable.

2. Odor Filter

Next, in line comes the carbon filter, which fails to perform as expected. These odor air filtration systems, while it is kind of thick, contain not that much carbon and they’re semi-translucent when held up to light. Even though this the Coway is good at removing dust and pollen, it won’t impress anyone with its odor-control capabilities.

Filters that target odor are also generally known as activated carbon filters. These filters can be effective at reducing odors because of the physical and chemical structure of the carbon.

Activated carbon is an extremely porous material that has the distinctive capability to target pollutants at an atomic level, making it possible to absorb specific chemicals as they come into contact with the filter.

3. True HEPA Filter

Upcoming in the Coway filter lineup is a True HEPA filter. With so many brands walking away from their older merchandise, filter access and supply is, in our opinion, more important than the filter price. The AP-1512HH needs replacements of the True HEPA filter once a year and 6 months for the carbon filter. Surprisingly, this short replacement interval offers lots of advantages for retailers to look after their inventories.

High-efficiency particulate air filters are the markets gold standard. HEPA filters consist of an ultra-fine fiber material that targets pollutants at a microscopic level. They’re so effective that they’re recommended by the Center for Disease Control to target pathogens and other hazardous contaminants in the atmosphere.

HEPA filters target a big range of pollutants and are particularly useful for people who suffer from asthma or allergies, both of which are triggered by the particulate matter that this filter is designed to eliminate.

A filtration change timer lights an indicator light when certain hours of use hit a particular point. The Coway company’s 1 Year Replacement Pack, part number 3304899, includes 1 HEPA filter and 2 carbon filters. The filter pack sells for an affordable $49.99 and is available Amazon.com (check for the latest price here).

Negative Ionizer

Next, comes the Ionizer, that is a straight forward negative ion emitter, but goes by the name “Coway Vital Ion Technology.” A separate switch turns the ionizer “on” and “off”. In the next paragraphs, we will highlight every stage of the filter process in the Coway AP-1512HH Mighty Air Purifier.

Air quality and filter change indicators

Understanding what is going on with the Coway air purifier is important in order to understand the air quality at home. The air quality indicator on the Coway makes use of particle sensor innovation and changes color depending on the air quality, so you always know with what kind of air quality you are dealing with. The other indication is for the filtration system.

It is important to change the carbon filter every 6 months and the HEPA filter annually, so the Coway will give you a sign to let you know when it is time for a change. You do not have to monitor the time yourself or worry that your filters are not doing their job well before they are past their expiration date.

Ease of Use and Maintenance

Most of the time, we basically have no control over the quality of the air we breathe. Nevertheless, the Coway AP-1512HH can significantly change that in any indoor area. This air purifier uses particle sensor technology working as an air quality indicator.

This offers very user-friendly operating, so you’re aware of the quality of air. As a common maintenance, and to guarantee maximum efficiency, you need to replace the filters occasionally. When these need to be changed depends on the frequency of use but on average like we described before, you’ll need to replace the HEPA filter annually and the carbon filters every 6 months.

The Coway AP-1512HH has smart particle sensor. It can select the fan speed based on the level of air quality. There are five configurations that you can select (low, medium, high, eco and auto). There’s a timer functionality that will instantly turn off the purifier after 2, 4, or 8 hours.

Both eco and auto-mode are similar, automatically handling the airflow speed depending on the air quality detected. The difference is on eco-mode, the fan stops automatically as soon as the air quality is good. This reduces power use and cuts down on energy bills.

CADR and Coverage Area

The Coway AP-1512HH has some impressive Clean Air Delivery Rating rates to its name. It has a CADR of 246 for dust, 240 for pollen and 233 for the smoke. These numbers are better than other competing brands like the Winix 5300-2.

Yet another thing is that this air purifier can easily cover a medium size living area of around 360 square feet. Thus, it’s “mighty” enough to filter the polluted air within a smaller living area.

Energy consumption and Silent operation

The fan on the Coway AP-1512HH model is different from the conventional air purifier fans that make noise when you turn them on. The Coway has a quiet operation and operates smoothly in any corner of your condo.

With the high-efficiency operation of this air purifier, you might be wondering about different side effects of the device. You can be assured knowing that you’d not face any problems while using this air purifier and anyone at home can manage to control it with convenience.

Together with the operational ease you also get many eco-friendly features alongside this air purifier. As pointed out above this smart sensing model automatically switches the fan “on” or “off” based on to the pollutants around you in the air.

This innovation not only saves on your energy bill but also comes as a boost for the people looking for eco-friendly practices that can support the environment.

The particle sensor system is, in fact, an effective technique to keep any kind of micro-bacterial development away from your home. The system keeps you in good health and eliminates any kind of nasty smell.

Who would not like to have a low energy consuming air purifier that supports the environment? The Coway AP 1512HH steps in as not just an option but a perfect answer to the problems many people face. It has been described by a number of users as the lowest energy consumption air purifier on the market.

At just 15.6 watt usage on the lowest fan setting, you can be sure this air purifier will go a long way to help you minimize your energy bill. To put the power consumption in perspective, the 15.6-watt consumption converts to 2.1 extra watts on what light bulbs usually consume.

Safety and Certification

With the 4-stage air filtration system, the Coway AP-1512HH is able to successfully clean the air in your room. Nevertheless, in the last filtration step, “Vital Ion” ionizes the air molecules. The charge subsequently is transferred to pollution particles so that these charged particles can be easier eliminated in the next air purification cycle.

A tiny percent of ionized air has a changeable effect to form ozone which may cause issues to the highly sensitive and painful lung.

Thankfully, Coway has shown and got the California Air Resource Board (CARB) certification to show that the air purifier creates lower than 0.05 ppm energized molecules. So the Coway AP-1512HH will probably not going to cause any breathing problem. Additionally, if you’re very concerned about this issue, you can switch off the “Vital Ion” ionizer.

A good element of this Coway air purifier is the energy consumption. Most of the large air purifier models use more than 60W at the lowest setting, but the Coway uses only 5W. In fact, it’s certified by “Energy Star” for the low power usage. This air purifier does not notably affect your electrical bill even when it’s operated 24 hours a day.

Upsides and Downsides


The Coway AP 1512HH is highly efficient, with a CADR rating of 210 for dust and particle cleaning, what better device would you get for its price range? Besides, the air purifier has a 4-stage air filtration system, which gets rid of all forms of dust and odor in your home.

From an air quality signal to a system that turns off when the air purification is done, the Coway is surely made to make air purifying a breeze. It’s no wonder that numerous Coway AP 1512HH users credit the brand for having world class functions for air purifiers. This air purifier has an “Energy Saving” star as well, and most of its features are geared to making sure that you pay the lowest energy bills possible.


There are varying ratings when it comes to how noisy the Coway AP-1512HH Mighty Air Purifier is. When it’s on high fan speed, it can be quite noisy but when it’s on low, it’s very quiet and you can barely hear it at all. There are a lot of elements that are great about this device, but one of the negative aspects is that it does not quite get rid of odors or chemical substances from the air.

Besides that, the air quality indicator is frequently not reliable. The air purifier is likely to increase the room’s temperatures, which kind of puts a dent on how practical it’s conserving energy in your house is. The Coway AP-1512HH manages to lose efficiency in larger areas. The Vital Ion component is not recommended for people with sensitive breathing issues.
