Keeping your Air Conditioning Clean is critically important for you families health.
One cause of indoor air contamination is due to bacterial and fungal contamination of air filters, heat transfer coils and duct-work within air conditioning systems that are poorly designed and maintained.
Air passes through dust filters prior to being cooled at the cooling coil and blown out from the air conditioner. Dust filters are usually intended to remove larger particles that would foul the cooling coil and aren't effective at removing small (respirable) airborne particles. As the larger particles are trapped by the filter, they form a layer that Improves the removal of repairable particles, but at the same time they reduce the air flow and (If they become wet) provide nutrients for fungi and mould to grow inside the air conditioner. Also, when air cools at the coil, It drops Its moisture to the coil surface and If this Is not allowed to drain away, fungi and bacteria can grow there too. Since the building air Is being circulated through this system, fungi and mould spores and bacteria and odorous VOCs are released through the use of the air conditioner and contaminate the air.
