What is the best method for removing odors from a house?

Ventilating the house is the most effective method for removing odors because it allows for the exchange of stale indoor air with fresh outside air. This process helps to dilute and eliminate lingering smells that have become trapped inside. Proper ventilation can significantly reduce concentrations of odors, making the environment more pleasant and healthier.

In contrast, covering odor sources may mask the smell temporarily but does not address the underlying issue. Using air fresheners can also provide a short-term solution by masking odors rather than eliminating them, which can lead to a cycle of needing to continuously use these products. Sealing windows and doors does not promote airflow and might actually worsen the problem by allowing odors to stagnate indoors. Therefore, ventilation is the most comprehensive approach to effectively removing odors from a house.
