Property expert Kirstie Allsopp has sparked controversy by labeling plug-in air freshener users “morons” who are “poisoning” their homes and loved ones. Allsopp’s comments on social media ignited a heated debate, with some supporting her stance and others defending the use of air fresheners. Despite her strong condemnation, experts advise using air fresheners in moderation and being mindful of potential sensitivities, especially for those with allergies or asthma.
