As Jakarta endures a wave of extreme heat and heavy rains, with temperatures soaring and humidity fluctuating, many people are retreating indoors, seeking comfort by cranking up the air conditioning. While this brings cool relief, it can create a false sense of security - air conditioning alone doesn’t guarantee cleaner air. In fact, the indoor air we rely on for refuge is often 2x to 5x more polluted than outdoor air, containing contaminants like dust, mold, and volatile organic compounds (VOCs) from household products, aerosol sprays, and furnishings. For anyone with allergies, asthma, or respiratory sensitivities, limiting these indoor pollutants is essential. Here are practical steps to keep your indoor air truly fresh and healthy, especially through Jakarta’s challenging heat wave and rainy season.
