Filter Types

The Coway air purifier comes with four filters, and each one is a powerful and effective component that removes harmful elements from the air.

  • Pre-filter – A washable filter that captures the largest particles, such as dust, dirt, hair, and pet fur.
  • Odor Filter – A special filter made out of activated carbon that traps odor particles and harmful gases. It also captures larger particles not trapped by the pre-filter.
  • True HEPA Filter – A high-performance filter that traps 99.97% of the finest contaminants down to 0.3 microns. It excels at removing airborne allergens, pet dander, bacteria, mold spores, factory and automobile exhaust smoke, and other common indoor contaminants.
  • Vital Ionizer – This feature boosts the cleaning power by charging airborne particles. This makes it easier for the other filters to trap particles and helps to freshen the air. It can be turned on and off.

Room Size Coverage

The Coway air purifier was designed with the average person’s needs in mind.

It doesn’t cover a massive amount of space nor is it restricted to being used in a tiny room.

Instead, the Coway AP-1512HH air purifier handles average size rooms up to 361 square feet (sq. ft.). This makes it an economical choice for a majority of people who need a high-quality air purifier.

In particular, this machine is ideal to be used in the following spaces:

  • Bedrooms
  • Living rooms
  • Dens
  • Dining rooms
  • Kitchens
  • Home offices
  • Smaller finished basement areas
  • Craft rooms and workshops

Coway Air Purifier CADR Rating

Clearly, an air purifier’s job is to remove impurities from the air.

And to prove that a device is effective at doing that, many manufacturers have their air purifiers independently tested by the Association of Home Appliance Manufacturers (AHAM) to get a Clean Air Delivery Rate Rating (CADR).

The purpose of this CADR test is to see how effective the machine is at removing dust, smoke, and pollen from the air.

If the numbers from the test are close to the room size coverage, then the machine is considered to be effective at removing that particular pollutant. The goal is to have a number in each category at least 2/3 the number of total square footage coverage.

This Coway air purifier scored the following CADR numbers:

  • Dust: 246
  • Smoke: 233
  • Pollen: 240

As you can see, the Coway Mighty Air purifier meets or exceeds the CADR ratings established by the AHAM. If you buy this air purifier, you’ll have a device that’s incredibly effective at removing the majority of contaminants found in the air.

Coway Air Purifier ACH Rating

Another important part of this Coway air purifier review is the ACH rating which tells you how often the device filters the air in the room every hour.

This Coway air purifier has a 4X ACH rating.

In rooms up to 361 sq. ft., this device can filter the full volume of air four times in one hour.

When you’re buying an air purifier, you want to look for at least a 4X ACH rating since it keeps the air in your home the freshest and cleanest from pollutants.

    • Blue = Clean
    • Purple = Medium Polluted
    • Red = Highly Polluted
  • Variable Air Flow Control – This device is equipped with three fan speeds which allow you to manually adjust the air output to fit your air purification needs.

  • Eco Mode – This is a standout feature that isn’t found on any other air purifier. Eco Mode ensures that your device is always running the most efficiently and saving you money in the process. When Eco Mode is turned on and the air purifier detects clean air quality in the room, the machine will go into a standby mode. Then, when air quality worsens, the air purifier will turn back on to quickly remove any contaminants. Eco Mode makes this Coway Mighty Air purifier one of the most energy-efficient and energy-saving products ever made.
  • Timer – If you need it, this machine can be set to run for 1, 4, or 8 hours before it turns completely off. This is a good option to have if you’re ever gone for long periods of time and don’t want the air purifier running when you’re not home.
