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.
