 Clean or Replace the filters regularly
  • There are lots of dangerous micro objects threatening our daily lives. Recently, people are increasingly concerned about the Indoor Air Quality (IAQ). Do you doubtful whether are you breathing clean air ?
  • The fact is, air does act as the vehicle of bacteria / virus transmission. There are lots of particles, dust mite, mold, pollen, etc. in the air. Bacteria / virus can stick to tiny particles and travel in the air for several hours. Infection may occur after inhalation of sufficient amount of these bacteria / virus carrying agents.
  • These carrying agents circulate around and anchor inside the air-conditioning system, especially air filters.
  • To prevent your air-conditioning system becoming the source of bacteria / virus dispersion, we should maintain the cleanliness of the system, particularly coils and air filters which should be cleaned regularly.

Web-Note Important : Prevent Aedes Mosquito Breeding
The virus that causes dengue fever and Zika are carried by the Aedes mosquito. As the bite of an infective Aedes mosquito spreads diseases, it is crucial to prevent its breeding. The Aedes mosquito is easily identifiable by the distinctive black and white stripes on its body. It prefers to breed in clean, stagnant water easily found in our homes. You can get rid of the Aedes mosquito by frequently checking and removing stagnant water in your premises.
