This will be a an interesting comparison, as I will compare two top-notch air purifiers, the Levoit LV-H134 and Coway AP-1512HH. The Levoit is a huge air purifier, uses a three-stage filtration technology, has plenty of options, and performed very well in all tests. The Coway is, on the other hand, a medium-sized air purifier, uses a three-stage filtration technology, and has plenty of options as well.
The Levoit LV-H134 covers rooms up to 492 sq. ft., which is significantly larger than 361 sq. ft., which is room coverage of the Coway AP-1512HH. The build quality of these two air purifiers is pretty okay, just as it has to be for this type of device. Coway comes in white or black, while the Levoit comes only in white. In my opinion, even though it’s too big, the Levoit looks somehow prettier and much more modern.
What else is important for both air purifiers is that they performed amazingly on performance tests. They also showed excellent performance in smoke box tests and passed without any trouble all other tests I performed.
The question is! Can the size judge, and will it be enough for the Levoit to beat Coway? You will find out the answer to this question in the article. I will compare their performance, noise levels, operating costs, and specifications, and in the end, I will declare a winner.

Coway AP-1512HH Vs Levoit LV-H134 Video Comparison
Which One Does It Better?
To summarize, this was not such an easy battle, and even though the Levoit LV-H134 is a much larger air purifier, which also has a huger airflow, I chose the Coway AP-1512HH as a winner and a better buying option.
The Coway has outstanding performance; it is quieter, has a possibility of setting the air quality sensor’s sensitivity, is slightly cheaper for maintenance annually, and has longer-lasting filters. Besides, it is one of the best air purifiers I have tested so far! Don’t get me wrong, the Levoit LV-H134 is also an incredibly good air purifier, and I would suggest it to anyone looking for an air purifier for rooms of 500 sq. ft. or larger.

Hi, I want to buy an air purifier to help with wildfire smoke. We do not have any allergies or lung issues but I want us to breathe clean air in summer. I prefer to buy one unit for the whole house which is just below 3000 sq.ft. I have read a lot of your awesome reviews but I am still very confused. Is Coway Ap-1512 a good option? It seems that it is a fantastic purifier but I am not sure it can handle our house. Have you reviewed Levoit LV-H133? how does it compare to Levoit LV-H134 and Coway? At least the filter is cheaper than Core 600s and LV-H134 so I can change it more freq. Any advice for me, please?
Hi,
I haven’t reviewed the LV-H133, but I can say that Levoit air purifiers, in general, use high-quality filters. With more than fifteen Levoit air purifiers tested, I can only say that whichever you choose, you can’t go wrong!
As for the Coway AP-1512HH, it’s not powerful enough for that square footage.
Hello team. I am find information about Mighty and I access to your website. I have a question to you: You said that “Coway Mighty (AP-1512HH) Ionizer will produce 1 million or 10^6 pcs/cm3 32ft”. It is truth? Because as I know, Coway do not publish the ion density produced by this machine. You you have checked, pls share me the result through my email
Thank you!
Hi, please keep in mind that the Coway emits ozone only when the Ionizer option is active.
I got the information about the ozone emission directly from the Coway USA support. You can contact them through their support email. You can also check the Energy Star certificate to confirm this information.
Thanks!
