Unless you are replacing the activated carbon filters every week or so, an air purifier won’t be capturing any meaningful amount of VOCs anyways. Manufacturers of filters seem to have decided it is OK to flat out LIE about how long activated carbon filtration is effective for before becoming saturated. Unless you have a massive filter budget, the only meaningful way to control indoor VOC levels is by venting in outdoor air (opening a window). If your automatic filter controller has a way to ignore VOC levels and only monitor particle counts, I would recommend you configure it that way.
