In reply to Nichole. The air quality light is always on. Are you having trouble resetting the filter reset indicator light, or is there other issue?

In reply to Susan. If the standard procedure doesn't work, press and hold the light and filter reset buttons at the same time. Then, the PRE light indicator will start blinking. After this, press and hold the filter reset button (located below the PRE and MAX2 indicators) for 2 seconds and the PRE indicator should be resseted.

In reply to Tim. Hmm, the only possibility that comes to my mind is a clogged air quality sensor, but you've mentioned that you have cleaned it. My suggestion is to adjust the sensitivity settings of the air quality sensor; this adjustment might resolve the issue. I explained this process in my review of the Coway AP-1512HH.

I have the model pictured in this article and am confused by the cycle it seems to go through. Every morning it runs on “red” on the auto setting for literally 3-4 hours straight. This is in the middle of the night and beginning of the day when I haven’t cooked anything yet, everyone has been asleep, etc. As I’m typing this it’s been on red for 5 hours. This cannot be right. I recently changed the filter, used a swab on the sensor and cleaned the unit. Nothing seems to work. In the past it will eventually switch back to blue but clearly my house does not have “very unhealthy” air quality for 5 hours. Any suggestions?

In reply to Sunil Gupta. The "Pre" refers to the pre-filter, which you need to clean periodically, usually at least once per month. After cleaning it, you have to reset the "pre" filter indicator. However, I can't provide more details on the resetting procedure without knowing the specific model you are talking about.

I have two LED indicator “Pre” and “HEPA/Carbon”.
My purifier is new just 10 days old but now “PRE” led is continuous glowing.

What is reason and how it may get down.

In reply to Victoras. It doesn't make sense to me; usually, there's an immediate improvement in air quality right after turning on the air purifier. If I were you, I would use the device for some time, then turn it off for 24 hours. After that, you should have a better sense of whether the Coway is effective in purifying the air or not. Regarding the air quality indicator, consider adjusting its sensitivity. I have explained the procedure in the Coway AP-1512HH review.

Hi,
I have a very small bedroom, and just received my Coway AP-1512 HH, I call the Amazon, and they told me to wait 2 days, it’s running for more then 48 hours, and still the air quality light it’s plane blue! I purchased this for purified the air and helped me with breathing clean air… Should I return it! It’s something wrong with the unit, I can feel on my breathing that the air is not clean.
Thank you in advance

In reply to Hattie Vogel. If your monitor doesn't display number values but only color readings, it's difficult to determine the current VOC concentration level. However, if your monitor reads red/purple, that means the air quality in your place is really bad, and you should leave your air purifier on maximum speed as much as possible.

hello,
Question about VOC’s and your monitors with carbon filters. The apartment next to mine had floors refinished 2 weeks ago with a toxic Swedish finish and my monitor (in my separate apartment) reads red/purple several times a day. What are VOC’s these monitors measure for? What concentration levels of VOC’s cause lights to change. I appreciate any info, thank you.
