My VOC levels are around 1 which is pretty bad. Bedroom with no ventilation apart from window that remains closed during winter. Opening the windows for 10 min changes from 1 to 3 stars but obviously I can’t let it open when temperatures are around 0C outside. Based on client testimonials and your own tests, would an air purifier improve (3 starts or above) a room of about 11 square meters? Thanks
