Why do moulds grow in our aircon and why is airconditioning the best way to spread moulds, bacteria, and viruses?

Moisture build-up in airconditioning systems is inevitable with a humid environment and condensation issues. And these provide the perfect breeding ground for moulds and bacteria to grow. If these mould and bacteria grow in the exterior part of the system, it can be cleaned away. But how about the areas we can't reach?

Airconditioning systems are the perfect breeding ground for molds and bacteria. A study done by Osaka City Institute of Public Health and Environmental Services showed that the average mold contamination of airconditioning filters was about 5-fold greater than that of a carpet!

If airconditioning systems are left untreated, we end up with:

  • The spread of invisible bacteria, and viruses
  • The growth of mould throughout the system
  • Musty smell/odour then using synthetic and strong smelling air fresheners to mask the musty smell.
  • Furniture, walls, ceiling, etc. that are mouldy.
  • Increased instances of sick building syndrome.
What is Sick Building Syndrome?

Definition from Wikipedia:
"Sick building syndrome (SBS) is a combination of ailments associated with an individual's place of work or residence. A 1984 World Health Organization report into the syndrome suggested up to 30% of new and remodeled buildings worldwide may be linked to symptoms of SBS. Most of the sick building syndrome is related to poor indoor air quality. Sick building causes are frequently pinned down to flaws in the heating, ventilation and air-conditioning (HVAC) systems.

Symptoms: Sensory irritation of the eyes, nose, throat; Neurotoxic or general health problems; Skin irritation & Nonspecific hypersensitivity reactions; and odor and taste sensations."

The symptoms referenced in the Wikipedia definition above are symptoms associated with mold and bacteria exposure.

A study in Australia showed that 2 out of 5 people suffer from sick building syndrome.

Mould and Bacteria Control All Year Round

      "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 breath 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
