Poor Air Quality in Container Houses

The poor air quality in container houses is mainly affected by factors such as ventilation, materials, and structural airtightness, and can be improved through measures such as opening windows for ventilation, adding ventilation equipment, optimizing material selection, and placing adsorbent items.

1. Ventilation Issues
   Container houses usually have limited space. If the doors and windows are not reasonably designed or insufficient in number, it can lead to poor air circulation, making it difficult for odors and pollutants to be expelled. The solution is to increase the number of ventilation openings, such as adding exhaust fans or fresh air systems, and keep the doors and windows open to create convection.

2. Material Issues
   To reduce costs, some container houses use flammable materials such as polystyrene and polyurethane foam for the sandwich layer, which may release harmful gases, or use inferior adhesives and wall panels, resulting in a decline in indoor air quality. The solution is to choose environmentally friendly materials, such as high-density thermal insulation rock wool and double-glazed aluminum windows, and prioritize purchasing products from large manufacturers, whose processes and material quality are more reliable.

3. Structural Airtightness Issues
   If the joints of the panels, the edges of doors and windows, and other positions in container houses are not tightly sealed, rainwater or humid air may seep in, leading to mold growth and unpleasant odors. The solution is to strengthen the sealing treatment, such as using waterproof membranes and sealants to fully seal the joints, and designing reasonable drainage slopes to avoid water accumulation.

4. Daily Maintenance and Auxiliary Measures

• Open Windows for Ventilation: Regularly open the doors and windows to promote air circulation and reduce the accumulation of odors and pollutants.
• Place Adsorbent Items: Place potted plants such as pothos, mint, and cactus indoors, or use charcoal bags and buckets of saltwater to adsorb odors and harmful substances in the air.
• Use Deodorizing Cleaners: Wipe the walls and floors with a cloth dipped in a deodorizing cleaner. Continuous use for several days can remove odors.
• Control Humidity: Keep the indoor environment dry to prevent mold growth in humid conditions. Use a dehumidifier if necessary.
