Whether natural or synthetic, high doses of chemicals can cause health problems. Gelair Air-conditioning Blocks release only small quantities of tea tree oil over a long period of time, making it a safe and environmentally friendly solution. Most people consider tea tree oil’s low odour to be “fresh” and “clean”. If you use Gelair as directed, it will not damage your health. We recommend storing Gelair safely away from children as it is toxic if ingested.
