In reply to Nancy Bearden. You can actually turn the lights off by holding the Ionizer button for 3s.

Hello and thank you for your very thorough and clearly stated review of AP-1512HH. I have read several comments about the unit lights being too bright when sleeping. Is this accurate. Thank you

In reply to Naomi.

Hi,

I use the AHAM-defined industry standard when determining a room coverage of an air purifier, which is 4.8 ACH (air changes per hour).

The Coway AP-1512HH can clean the air 4.8 times in a room of 361 sq. ft. But, it also can clean the air 2 times in a room of 874 sq. ft.

My answer is yes, you can use it in larger rooms (but less polluted), but keep in mind that it is the most efficient in rooms of up to 361 sq. ft.

How would this filter work in a room that was about 700sq ft? I see that your review says it is for a room about half that size but I am looking at the specs for various Coway filters on Amazon and it says it is good for 109m3/1173sq ft. That’s quite a difference. Could you help me understand the implications of using it in a room that is about 700sq ft? Presuming that the CADR would be halved? But it would not be ineffective? Thank you so much.

Hi Steven. Thanks for your comment.

Yes, there is a timer inside, so the device doesn’t track the filter’s dirty.

As for resetting the filter section, I made a typo there. You must press and hold the “Filter Reset” instead of the “Power” button. Thanks for pointing out the typo.

Thanks for the review, Milan. And I have 2 questions. When the HEPA filter is replaced the filter reset indicator must then be reset. Does this mean the filter reset indicator runs on a 1-year timer as opposed to some other method to indicate time to change the filter – such as automatically sensing decreased air flow thru dirty filter, etc.? Also, to reset the filter-reset indicator do you press the power button or the filter-reset button? You mention in step #5 the power button should be pressed for 2 seconds but the photo shows your finger on the filter reset button.

are you guys able to do a ozone test on the Coway AP-1512HH True HEPA Air Purifier when the ionizer is turned on and when it is turned off i have been researching if this air purifier emits ozone when ionizer is turned off and i am getting different answers

In reply to Linda. Thank you for such a great comment! You could try changing the sensitivity of the sensor if you think it's not sensitive enough. I explained the process of changing the air quality sensor sensitivity in the review.

Wow! Thank you for the detailed review. I am much more confident now that I made the right choice when I purchased this model. I hadn’t seen your page when I was researching but this model came highly recommended though not so thoroughly reviewed. We have had it for just three days now and getting used to how it works. I’ve moved it through the day to different rooms and it only turned purple for a while in the kitchen while cooking otherwise it’s hard to know if it’s doing what’s its supposed to as it’s always blue (a good thing I suppose!). I will keep your page handy for reference. Thanks again

In reply to Looking for Purifier. The Coway would work best if you had an open space. But, as you have separated rooms I would suggest a smaller air purifier such as Levoit Core 300 for every room.

If my rooms are smaller than 320 sq ft but my total home is 320 sq ft, should I buy a single coway or separate but lower sized purifiers ? What would be your recommandation ? If I put this one of the rooms does it make sense for all home even if bedrooms and living room are a bit far from each ?

In reply to Sarah Bardin. Hi! You don't have to remove a piece of foam located in the particles sensor box. Actually, the first one is the most sensitive setting, so please try switching the sensor sensitivity to the first option.

Thank you for this, as I found the manual confusing to navigate. Quick question: I just bought a Coway Mighty and set it up yesterday. When I open the particle sensor there is a small rectangular piece of foam stuck to the inside flap. Am I supposed to remove it, or it stays there? The reason I ask is that to my surprise, when I put the air purifier on “auto” it seems to stay on “blue” all the time, except when I opened the the particle sensor to look at it. I set the sensitivity to 3, which I believe is the highest, using your instructions. Any thoughts would be appreciated. You are performing such a great public service. Thank you.

In reply to Wayne. You can use the Coway AP-1512HH without a carbon filter, but that is not recommended because it would decrease the air purifying performance. The cheapest solution I can suggest is buying a replacement filter from any third-part distributer, which you can find many on Amazon.

Since you only get 1 carbon filter with the unit, where do I get another? The website has them for a ridiculous $20. Can I stretch it out, or use it without the carbon filter?
