AerisGuard™ Coil Cleaner

The AerisGuard™ Coil Cleaner is applied to cooling and heating coils to remove any existing bacteria or fungi, ensuring the coils are clean.

Why Do We Need To Clean Air Conditioners and Dehumidifiers

Solely cleaning the filter is not enough to prevent allergy attack and infection of diseases. Allergens, bacteria and mould would not only grow on the air-con surface, but also in air grille or fan coil as dust and dirt accumulate. We recommend you to clean the A/C unit every once in a year to improve you and your family member’s health. Stay away from allergies, and maintaining the efficient of the A/C.
