9. Scent and Air Quality

Designers are highly attuned to the scent and air quality the moment they step inside a home. Whether the air is fresh, filled with inviting floral notes, or tinged with mustiness, scent strongly influences first impressions and the perceived cleanliness of a space.
Unpleasant odors can make even a well-decorated home feel unwelcoming, while fresh air or subtle fragrances create a positive ambiance. Good ventilation is crucial for maintaining healthy air quality and removing lingering smells. For tips on improving your home’s scent, see Good Housekeeping.
