Explanation:
If you cannot achieve effective ventilation, it means that there is a lack of fresh air flowing into the indoor space, leading to an accumulation of pollutants. To troubleshoot this issue, there are several steps you can take:
- Check if the windows and doors are properly sealed. If there are any gaps or cracks, they should be sealed to prevent air leakage.
- Ensure that the exhaust fans in the bathroom and kitchen are functioning properly and remove any blockages that might be restricting air flow.
- If mechanical ventilation devices are installed, make sure they are clean and in good working condition.
- Consider using air purifiers or filters to remove pollutants from the air.
- Maintain a clean indoor environment by regularly dusting, vacuuming, and keeping the space well-ventilated.
