Maintain Optimal Humidity Levels

A humidifier or dehumidifier should maintain indoor humidity between 30% and 50%. This range helps prevent dry air discomfort and inhibits mold and bacteria growth.

Regularly Clean and Replace Filters

Clean or replace aircon filters according to manufacturer guidelines to ensure optimal air quality and prevent the buildup of airborne particles.

Use Programmable Thermostats

Set your aircon to a moderate temperature and use programmable thermostats to avoid drastic temperature fluctuations, which can strain the body’s respiratory system.

Ventilate Indoor Spaces

Open windows and doors allow fresh air to circulate indoors when outdoor conditions permit. This helps refresh indoor air and reduce stale air buildup.
