If you’re looking for a high-quality and highly effective Air Purifier, Coway is likely at the top of your list. So it’s worth a closer look.

Key Features

  1. HEPA Filtration: Coway air purifiers are equipped with True HEPA filters, capable of capturing 99.97% of airborne particles as small as 0.3 microns. This includes dust, pollen, smoke, and other allergens, making it highly effective for allergy sufferers.
  2. Pre-Filter and Carbon Filter: In addition to the HEPA filter, Coway models typically include a pre-filter and an activated carbon filter. The pre-filter catches larger particles, extending the life of the HEPA filter, while the carbon filter helps remove odors and volatile organic compounds (VOCs).
  3. Smart Technology: Many Coway air purifiers come with smart features such as air quality indicators, auto mode, and timers. These features help optimize the purifier’s performance and energy efficiency.
  4. Quiet Operation: Designed with noise reduction in mind, Coway air purifiers operate quietly, making them suitable for use in bedrooms, offices, and other quiet spaces.
  5. Sleek Design: Coway models often feature modern, sleek designs that blend well with various home decors.


Coway air purifiers consistently receive high marks for their performance. The combination of HEPA and carbon filters ensures comprehensive air cleaning, effectively reducing allergens, odors, and harmful particles in the air. Users frequently report noticeable improvements in air quality, with many noting relief from allergy symptoms and a reduction in indoor pollutants.

The smart features, such as real-time air quality monitoring and auto mode, enhance user experience by adjusting the purifier’s settings based on the current air quality. This not only ensures optimal performance but also helps conserve energy.

Energy Efficiency

Coway air purifiers are designed with energy efficiency in mind. Many models are Energy Star certified, indicating they meet strict energy efficiency guidelines set by the U.S. Environmental Protection Agency. The auto mode feature, which adjusts the fan speed based on air quality, further contributes to energy savings.


Maintenance is straightforward, with filters that are easy to access and replace. The pre-filter is washable, which helps reduce the frequency of replacing the HEPA and carbon filters. Coway typically provides filter replacement indicators, so users know exactly when it’s time for a change, ensuring the purifier operates at peak efficiency.

Customer Reviews

Customer feedback for Coway air purifiers is overwhelmingly positive. Users praise the effectiveness in improving air quality, ease of use, and the smart features that make operation hassle-free. The quiet operation and stylish design are additional aspects that customers appreciate.


Coway air purifiers are competitively priced, offering good value for the features and performance they deliver. While the initial cost may be higher than some budget models, the long-term benefits, energy efficiency, and effective air cleaning make them a worthwhile investment.

As such, Air Purifiers have become modern appliances over the years, but Coway is one of the brands that have managed to stand out above all others by delivering high-quality devices capable of doing a great job at reasonable prices.

How Do I Choose the Right Coway Air Purifier Model?

Space. If you’re trying to clean a small bedroom, you’ll want to buy a smaller Air Purifier. On the other hand, bigger rooms require more power from the air purifier. For small rooms, choose Coway Airmega AP1512; for large rooms – Coway Airmega 400S

Noise level. The larger the Coway air purifier is, the noisier it will be. It can be an issue if you’re running it while you sleep or have young children sensitive to loud noises.

Air quality. Determine which allergens are causing problems for your family, and then find a Coway air purifier that targets those allergens specifically. 

Sensors. Intelligent sensors automatically detect when you’re home and when you’re not and adjust the fan speed accordingly.

Cost. The more features you choose, the greater the price tag will be. For example, the cost of running an air purifier is dependent on how much power it uses and how often it runs.

Remotes & Schedules. If you like to control your settings from afar or at night, look for an Air Purifier that comes together with a remote control or scheduling capabilities.

5 Tips On What To Look For When Buying Coway Air Purifier

Here are some tips that will benefit you to make a better decision:

  1. First, ensure that it is energy efficient. 

It is essential because if the Coway Air Purifier uses too much electricity, it can cost you more than you bargained for. Look for an estimated annual operating cost posted on the manufacturer’s website.

  1. Check whether it has an automatic shut-off feature.

An Air Purifier with an automatic shut-off will stop running when the air quality reaches its peak. After a few hours or so, the air quality will go down again, and then the cleaner will power itself up again to cleanse the environment once more.

  1. Check whether it produces ozone gas during operation.

Although ozone gas is not harmful to health, some individuals suffer from breathing difficulties and asthma attacks when they breathe in the fresh air having ozone gas in it. 

  1. Purification process

Air Purifiers use different technologies to filter air. The most common purification processes are HEPA, activated carbon, ionizers, and ozone generators.

  1. Filter indicator

An Air Purifier with a filter indicator will help you change the filters timely for better performance and efficiency of the unit. In addition, this feature enables you to save money on replacement parts that you may not need if the filters are changed.

People Also Ask

Is Coway true HEPA?

Yes, it is. HEPA stands for High-Efficiency Particulate Air. An air filter can remove 99.97% of particles (0.3 microns and larger) from the air passing through it. To be called a true HEPA filter, the filter must meet the minimum efficiency rating point (MERV) of 17. 

The Coway is a MERV 16 filter which is very close to being a true HEPA filter, and in most cases, it will perform like one.

Three parts of Coway Filters

1) An activated carbon pre-filter helps trap large dust particles, pet hair, and dander.

2) A True HEPA filter traps small dust particles, pollen, mold spores, bacteria, and viruses.

3) An ionizer that emits negative ions into the air around you helps break down airborne particles so they can be trapped easier by the other two filters.

Which brand of air purifier is the best?

The Air Purifier you choose will depend on what you’re trying to ensure it stays out of the air and how much space you need to cover.

Each brand offers a variety of options, including:
