Tea Tree Oil - Nature's Best
Mould control using nature's finest Australian Tea Tree Oil by Gelair.

Tea tree oil is a very powerful anti-fungal, anti-viral, and anti-bacterial. Tea tree oil was so valued in the 1940s that cutters and producers were exempted from military service during the Second World War.
Free from toxic chemicals. Only the best nature has to offer.

No expensive equipment required.

Made in Australia.

Written Testimonials
"Before I used Gelair Health-e SPLIT, my ceiling and walls have a lot of molds - we have to clean our walls and ceiling every month during the humid months! After using Gelair Health-e SPLIT, the molds didn't come back. My son can breathe better. Friends that come over asked if we did anything as our apartment feels fresh and comfortable, but no one can smell the tea tree oil. I'm very happy with the results, and my friends also purchased Gelair Health-e SPLIT." - Victor C., Tuen Mun

"My place has a musty smell, and we tried everything to get rid of it and no matter what we do, we never got rid of the smell. I even got one of those expensive air purifiers. A friend recommended Gelair Health-e SPLIT as he thinks it might be from our aircons. After we put Gelair Health-e SPLIT in all our airconditioners, the smell of tea tree oil was quite strong, but after a few days, we don't smell it anymore, and also the musty smell is gone! The Health-e Split worked for about two months before I had to replace it. The best part - my family felt better! No more sneezes in the mornings!" - Grace M., Mid-Levels

"At first, I didn't like the Health-e Split as I don't like the smell of tea tree oil. But the smell is only for a few days. After that I hardly smell the tea tree oil anymore but I can feel that the air is better." - Tony, Wan Chai

"My office is in an old building, and I receive a lot of clients in my office. They are very surprised that the atmosphere in the office is so different than the outside hallway. A lot of people asked what I'm doing - they thought I have one of those expensive air purifiers. I told them I have Gelair Health-e SPLIT." - Tina., Sheung Wan
