^ Replacement filters/ estimated 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.
We seen huge discount (around 30-40%) for the White version on Amazon. Not so much on the Black version but it's there. You can purchase of Coway AP-1512HH Mighty air purifier on the official website, Walmart, Target, BestBuy, HomeDepot, Lowe's, or Costco but our pick has to be Amazon as it has low/ free shipping, best online deal, and hassle-free return if you are not completely satisfied.

Coway AP-1012GH VS the challengers

Winix 5500-2 PlasmaWave

Winix 5500-2

A worthy competitor that is around the same price bracket, same specification, same features, and same filtration setup. Winix 5500-2 has the advantage of slightly wider purifying range while Coway Mighty has the upper hand on filter replacement cost.
Winix HR1000 5-Stage-Wifi-Enabled-Air-Cleaner-0

Winix HR1000

Everything is better if you are willing to splash some extra cash and filter maintenance cost. HR1000 on paper should be a better alternative that excels in almost every part. You will also gain the Wi-Fi enabled feature that supports remote access via iOS or Android app.
Honeywell HPA300

Honeywell HPA300

If you don't mind the lack of features like Auto mode, Eco mode, and an inferior carbon pre-filter, Honeywell HPA300 True Allergen Remover is a good replacement for someone that needed the raw airflow performance power and nothing else.
Rabbit Air BioGS 2.0 SPA-550A

Rabbit Air BioGS 2.0 SPA-550A

The most expensive alternative in the list yet with a poorer airflow performance. It is the filtration set (BioGS HEPA Filter + Charcoal Activated Carbon Filter) that pushes BioGS into this consideration list. The inclusion of remote control doesn't sound too bad either.

Final thoughts on Coway AP-1012GH

Dated it is, but lack of quality it is not. Coway Mighty is a very popular air purifier between its user base with a high 84% positive 4-5 stars ratings. Most compliments received are coming from filtration quality, followed by the noise level, sturdiness, and lastly pricing. The 11% dissatisfied customer complains mostly of two things: the fan motor that abruptly "make noise" and the poor customer support. Thankfully our few test unit is working fine and I am assuming most positive feedback driven user would experience the same.
