The hidden cost of odour complaints in hotels: protect your reviews, protect your revenue


In the hospitality industry, guest experience is everything. One of the most common (and damaging) complaints across review platforms relates to unpleasant odours. Whether from smoking, food, damp, or poor washroom hygiene, these smells undermine perceptions of cleanliness and professionalism.

Why odour complaints matter
Bad smells create a lasting impression. Even if the room is spotless, a lingering odour can suggest that it is unclean or poorly maintained. Guests may not mention it at reception, but it often appears in public reviews, reducing your rating and deterring future bookings.

According to recent industry surveys (for example, the Ecolab Hotel Cleanliness Consumer Survey), cleanliness and odours are key drivers of guest reviews: odours rank among the top negatives.
• Cleanliness is one of the top three drivers of hotel reviews
• Even one negative review can significantly lower average ratings
• Many guests interpret odours as signs of poor hygiene

What causes persistent smells?
Common causes of persistent odours in hotels:
• Smoke from tobacco or vaping
• Food from in-room dining or guest leftovers
• Pets and pet bedding in pet-friendly rooms
• Mould and damp in older or poorly ventilated spaces
• Poorly ventilated washrooms and waste areas
Sprays and fragrances might mask these temporarily but do not remove the cause.

AIRsteril units eliminate odours and volatile organic compounds whilst neutralising bacteria. In guest rooms, washrooms, corridors or back of house areas, AIRsteril helps:
