Our Recommended Coway Air Purifiers in 2022

It goes without saying that inhaling airborne pollutants all day long is not going to do your health. Whether you realize it or not, our indoor air can be just as polluted as the air outside. To solve this problem, you don’t need to cover your home, apartment, or office building in cling film. An air purifier is all you need to snatch lung irritants out of the air.¨

Today, we’re looking at air purifiers by Coway, a South Korean manufacturer of household appliances. At the end of this guide, you should have a good idea of what Coway air purifiers have to offer.

Coway AP-1216L Tower Mighty Air Purifier

Now introducing the one and only tower air purifier on this list. Tower air purifiers aren’t exactly new, and some clients may prefer larger machines for filtering and moving greater quantities of air each hour.

But don’t be fooled by the “tower” design; the Coway AP-1216L is actually lightweight (13.9 lbs) and takes up very little space (10.7 x 10.5 x 32.7 inches).

Coway AP-1216L
Coway AP-1216L

The AP-1216L tower air purifier by Coway features the 4-stage pre-filter, carbon filter, HEPA filter, and ionizer we know and love. The pre-filter is washable and reusable and, combined with the carbon filter, keeps the 99.7% HEPA filter cleaner for extended periods of time so replacements are infrequent.

For those of you who don’t identify and hardcore, environmentally-aware consumers, you may benefit from the lack of an eco mode. The eco mode in the other air purifier models serves to keep the machine running using minimal power.

However, the auto mode in this Energy Star-certified air purifying device only uses as much fan speed and energy necessary for optimal, time-efficient cleaning.

The AP-1216L also features air quality indicators and a 1/4/8/12-hour timer. The control panel on the front-facing top panel of the tower is easy to understand and use. If you need your air filtered for 12 hours, just push the button and you’re all set.

The problems customers have found with the LED lights. Coway really seems to love its LED lights and oftentimes the customer suffers. If you’re afraid of the dark, this air purifier also serves as an effective nightlight. Performance-wise, it performs just as well as, if not better than, direct competitors.

Coway AP-1512HH Mighty Air Purifier

The Coway AP-1512HH HEPA Air Purifier uses a 4-stage filtering process for sieving the air. It also features a timer, air quality indicator, and an eco mode to save energy. Don’t be fooled by the relatively compact size and beautiful design; this air filtration device packs enough punch to effectively purify the air in rooms of up to 528 square feet (claims by Coway).

In addition to the traditional 2-stage purifying process that most air filterers have, Coway has knocked it up a notch (or two) by throwing in a micro-mesh layer and an ionizer for good measure. The metallic mesh layer serves to trap large particles such as dust and pet hair, and it’s easy to clean which in turn prolongs the life of the carbon and HEPA filters; just detach the mesh and tap it against a garbage can.

This device has 5-speed settings, but auto and eco modes are all you really need. Auto mode conveniently alters the fan speed depending on how polluted your air is. When the machine detects good quality air for 30 minutes, it’ll switch to eco mode and then turn off until it’s needed again. This is especially handy for people who don’t have the time to babysit their air purifier.

Companies tend to exaggerate the performance of their machines, and Coway is no exception. Though the company boasts of 528 square feet purifying coverage, this compact unit performs well only in much smaller areas. Despite being a compact air purifier that runs with a noise level of between 24.4 and 53.8 dBa, some customers have complained about loud, disturbing fan noises, especially during the nighttime.

In place of standard carbon and HEPA filters, the Airmega 250 uses the Max2 Filter, which combines the deodorizing power of carbon with the high-efficiency of Green True HEPA to snatch 0.01-micron particles out of the air with 99.99% efficiency.

What’s more is that its pollution sensor has an LED indicator, which informs users of how polluted the indoor air is. The sensor will also trigger the device’s motor to turn on and off when needed.

Coway Air Purifier Buying Guide

In this section, we’ll go briefly cover the history of Coway, explain what features make their air purifiers so unique.

A Brief Look at Coway’s History

Coway started off selling water filters from door to door. Just five years after the company was established in South Korea, it began researching and manufacturing its first air purifier model. Today, it’s a conglomerate that has expanded into several unrelated fields, including beauty and rental. While Coway is still true to its water-purifying roots, it’s often regarded as being one of the top air purifier manufacturers in all of Asia.

Coway Air Purifier’s Unique Features

Triple- and Quatro-Power Suction

Many of Coway’s air purifiers feature three or four air intake ports. Inside of the air purifiers are two oversized fans that suction in the air from multiple directions, meaning you don’t have to think about the device’s placement for optimal cleaning performance.

Wide Air Circulation

The reach of Coway’s air purifiers varies from model to model. The larger Coway air purifiers are able to clean extra-spacious rooms of over 1,000 square feet. One or two of these air purifiers can purify the air in an entire home, let alone an apartment or a dorm room.

Built-in Humidifiers

If you live in a part of the world that gets unbearably dry in the winter, then you should consider getting an air purifier with a built-in humidifier. Coway’s 2-in-1 air purifier saturates the air at a rate of up to 600 mL per hour, raising the relative humidity level of a room to between 40 and 60%. What’s more is that the air purifier has a self-sanitizing feature to ensure that the water tank is as clean as possible at all times.

Self-Learning

One of Coway’s air purifiers is a self-learning device. The air purifier recognizes the homeowner’s habits regarding how frequently they turn on the air purifier, for how long, and fan speed is activated. This is definitely a nice-to-have feature that makes owning an air purifier even more convenient. Even though self-learning devices are relatively new in the market, Coway’s super-smart air purifier definitely shows some promise.

Smart Mode

The best convenience-adding feature you can get in an air purifier is a Smart Mode feature. A built-in air-quality sensor constantly checks the concentration levels of airborne particles. After reaching a certain threshold, the air purifier will automatically start up on one of its cleaning modes. Basically, all you need to do is set it and forget it. You can check up on the device every month or so to see whether the filter indicator light is on or not.

MAX2 Filter

Coway manufacturers a unique, all-in-one filter knows as the MAX2 Filter. It combines both a HEPA filter with an activated carbon filter. Both filters work in tandem to remove 99.97% of particles as small as 0.3 microns in size, as well as to get rid of odors from cigarette smoke and toxic fumes. While it can be harder to shop for MAX2 Filter replacements at brick-and-mortar retailers, they’re always available online. Every MAX2 Filter lasts up to 12 months.

FAQs

1. Does Coway Air Purifier work?

Yes, they do. Coway air purifiers are known for their top-notch performance in cleaning spacious rooms. Many of Coway’s devices have CADR ratings of over 230 in at least one category (smoke, dust, or pollen), so there’s no reason to worry whether your Coway air purifier will work as expected. Also, because these devices come with both multiple air intake ports and a HEPA filter, even the smaller Coway models can ensure noticeably cleaner air in shorter amounts of time.

2. Where are Coway air purifiers made?

All of Coway’s air purifiers are designed and manufactured in the company’s home country of South Korea.

3. Are HEPA air purifiers worth it?

Yes, they are. HEPA filters are considerably more expensive compared to standard, reusable filters, but their ability to retain microscopic particles (0.3 microns) at 99.97% efficiency is what makes them the perfect tool for sufferers of pet and/or seasonal allergies.

4. Does air purifier reduce dust?

All air purifiers are designed to suction and trap dust particles from the air. Depending on the device’s filters, they can even trap pollen and VOCs to make the air in a room fresher and healthier. It’s generally a good idea to look at the type and quantity of filters in an air purifier to determine how effective it can remove dust and other airborne contaminants.

5. Where should an air purifier be placed in a room?

Most air purifiers work best when placed in the corner of a room with their back sitting flush against a wall. However, it ultimately depends on the design of the air purifier—specifically, the location of the air intake port(s). Some air purifiers even hang on walls to save floor space while also beautifying bare walls.
