Recent reports indicate that many cities in Indonesia are facing heightened pollution levels. For urban dwellers, this directly impacts their health and well-being. It is no wonder that cases of respiratory infection are on the rise. Solutions like planting dust and pollution filtering plants indoor has been deemed ineffective. Moreover, home designs that emphasize cross-ventilation may actually worsen the indoor air quality when the outdoor air is polluted, as pollutants could easily permeate into the house.

To enjoy clean air in the middle of a polluted city, one of the most practical solutions is to implement air conditioning at home. Air conditioning can regulate airflow, temperature, and air quality, and can be conveniently carried out with appliances such as AC and air purifier. To ensure these appliances perform effectively, it is essential to make sure that the airtightness within the house is optimal. In this regard, the role of doors, windows and other openings is crucial to ensure proper air circulation and conditioning.

One solution to achieving better airtightness in a home is the use of aluminum doors and windows.  Generally, high quality aluminum doors and windows are manufactured with precision and installed by technicians to guarantee proper sealing when the doors and windows are closed. These aluminum doors and windows usually even comes with air-tightness specification to meet the requirement for the preferred air circulation needs in a house. For instance, numerous doors and windows product from TOSTEM feature superior air-tightness specification that can prevent PM2.5 particles from entering the home's interior. With the support of an air purifier, residents can enjoy clean air throughout the day.

Aluminum doors and windows are also ideal because of their adaptability to surrounding air quality. When outdoor pollution is low and the air is safe to breath, the large openings of aluminum doors and windows can maximize airflow from the outside to inside. Of course, this can be achieved with proper planning of doors and windows placement to ensure favorable cross-ventilation.

One of TOSTEM's product lines, ATIS, could be equipped with an optional feature for aluminum doors and windows when being opened. The feature, insect screen, aside from being able to prevent mosquitos, flies, and other insects to enter the house, could still allow air to flow inside. The thin yet tight insect screen from ATIS also make sure the view to the outside remains unobstructed while maintaining optimal airflow.
