Coway AP-1512HH Mighty review

The starters

Available in black and white, Coway AP-1512HH is perhaps the most underrated air purifier in the market that many people overlooked. Given it’s a dated model, the design might not be the most practical with air quality indicator hidden from the front sight. The plastic cover front panel with big circle budge does not feel premium, but the all-around design is sturdy that will prevent any off-gassing. At 16.8 x 18.3 x 9.6 in and 12.3 lb weight, the air inlet is nicely tugged on both sides with air outlet located at the back.

Moving to the controls, at the top you will find 5 round buttons and an air quality indicator. Starting from the left is the Power button that requires no explanation. Next to it is the speed button will top indicator that will cycle between Auto, 1, 2, 3, and Eco mode. The center Ionizer button will either enable or disable the Ionizer function. The fourth button belongs to Timer that will cycle between 1, 4, 8 hours, and off. The fifth Filter Reset button will reset either the Odor or HEPA filter count timer by pressing and holding the button for 2 seconds. A hidden function that is not shown on the screen is the Air Quality Sensor adjustment. To make any adjustment, press both airflow speed and ionizer button for 2 seconds. A beep sound can be heard and the speed indicator will blink to show the current sensor sensitivity. Press the speed button to cycle between speed 1 (Sensitive), speed 2 (Standard), and speed 3 (Insensitive). Repeat pressing both airflow speed and ionizer button for 2 seconds to save the setting. Last but not least, there is an air quality indicator that will display in Blue when air is clean, Dark purple when air polluted, and Red when air is highly polluted.

To wrap-up on the spec sheet, Coway Mighty comes with 4-stage filtration with 3 speed, 2 filter replacement indicator, Auto mode, Eco mode, 3 preset sensor setting, Energy Star rated and 3 years warranty.

Airflow, speed, and CADR

Coway AP-1512HH Mighty 3 speed and 326 sq. ft. coverage is best used in medium size room but you could place it in the living hall as well. Bedroom is also doable as that is the place you would spend the most time in. We always encourage users to leave it to Auto mode as an air purifier should not be a hindrance on your busy schedule. Speaking of Auto mode, it is highly reliant on the sensors to provide feedback and the good thing is the sensors can be adjusted to 3 different sensitivity. We have no problem with the speed consistency and sensor accuracy other than a few occasional hiccups. Let's get on with the clean air delivery rate test. You have the Dust CADR at 246 cfm, Pollen CADR at 240 cfm, and Smoke CADR is at 233 cfm. Decent output as it passes our 200 cfm benchmark but not over the top, In any case, the air purifier would have no problem handling household allergens and gas particles within its purifying zone.

What’s inside count

Coway Mighty utilizes the familiar 4-stage filtration that consists of pre-filter, True HEPA filter, Deodorization filter, and Vital Ionizer. Starting with the pre-filter that focus on large particles like dust and hair, follow by HEPA filter that captures fine particles as small as 0.3 microns with 99.97% efficiency rate. The deodorization filter will target smoke and gas particles that are not targeted by HEPA filter. Finally, Vital ionizer will cause particles to fall so it can be captured by existing filter. Overall, filter size is good apart from the deodorization filter that has a shorter lifespan.

Keep it down

Most users are happy with Coway AP-1512HH produced noise level particularly at speed 1. While the official figure is between 24.4 - 53.8 dBA which is market average, you will be able to run it over the night by leaving the setting in Auto mode. As an Energy Star Rated unit, the power consumption is very low especially with the Eco mode feature that stops the fan from operating when there are no pollutants nearby. At the most energy-saving mode, power usage is a mere 4.9 watts per hour. Way lower than its competitor's peer.

At what cost

Coway AP-1512HH Mighty is at a Sweet spot between affordable to reasonable price group that most buyers would go for. Most air purifier in this category would offer more or less the same package barring a few features. The thing that makes Coway Mighty so attractive is the low annual filter replacement cost that is less than half of some competitors model. With such a low filter price and plenty of available stocks, there is no need to risk it for third-party alternatives.
