This is my second purifier TP09, as I returned and replaced the original due to the intermittent high pitch squealing sound that it produces and now the 2nd model is doing the same thing. I've researched the community as well as a few other online communities and it concerns me that many people have this same issue and it has not really been addressed as to why and what is the cause. I do not want to visit a repair center as I've stated that is my 2nd machine and therefore it's not an isolated issue.
It seems to me that there is a flaw in the design that is not being addressed. It doesn't make sense why it works perfectly fine until it doesn't. If I change the setting from Auto to a number less than 7 I can hear the high pitch sound loudly, 7 - 10 and it can not be heard that much due to the wind speed overpowering however that is not an appropriate sound level to hear all day and after running at that speed for long enough the high pitch starts up again.
Many people are attempting to purifier their homes, all day, using the auto setting however it seems that is not being tested prior to releasing the product to the public as if it was, it would be heard.
The sound is very annoying and causes panic attacks for those of us that are sensitive.
Please advise as to what can be done to rectify this. All the hours of troubleshooting and messing with the machine are starting to outweigh the benefits as I end up turning it off most of the time.
I’ve been sending emails and am no longer receiving a response. It has nothing to do with CM settings and I feel slighted at the amount of money spent and again the lack of response.
What do I do at this point?
