Top 5 reasons odours persist in care homes (and how to solve them)

Unpleasant odours are one of the most frequent complaints in care environments, and often among the most difficult to manage effectively. Even highly maintained homes may struggle with lingering smells in corridors, bedrooms and shared spaces. Understanding the root causes is essential for sustainable control.

1. Odours from continence issues and personal care
Incontinence and reduced mobility, particularly in dementia care, are common sources of odours. A care home's first impression is often shaped by whether uncomfortable smells are present.

Practical solutions:
• Maintain strong hygiene routines and prompt waste removal.
• Replace carpets with easy clean flooring to prevent odour absorption.
• In rooms with poor airflow, support cleaning with validated air treatment technology that breaks down odours rather than attempting to mask them.

2. Odours trapped in soft furnishings and porous surfaces
Fabrics and upholstery often retain smells even after cleaning, especially in areas with limited ventilation.

Practical solutions:
• Choose furniture and curtains made from odour-resistant materials.
• Use washable covers on chairs and beds in high-risk areas.
• Combine this with air treatment to reduce the build-up of airborne contaminants in soft furnishings.

3. Cross-contamination from communal areas
Frequent movement between communal and private spaces spreads odours from kitchens, washrooms or waste areas throughout the building. This issue worsens when doors are left open or airflow is minimal.

Practical solutions:
• Increase checks and cleaning in high-use zones.
• Identify and isolate odour hotspots.
• Use localised air treatment to manage odours before they spread into other areas.

4. Inadequate ventilation or unsuitable extraction
Many care homes are older properties not designed with airflow in mind. Stagnant air causes smells to linger, and opening windows is not always practical, cold draughts or allergens can create discomfort.

Practical solutions:
• Use extractor fans or trickle vents to support consistent airflow.
• Balance fresh air with resident comfort and safety.
• Where natural ventilation is limited, consider continuous air treatment that does not rely on open windows or chemical sprays.

5. Reliance on masking sprays or perfumes
Fragranced products may offer a brief sense of freshness, but they often combine with existing odours to create a heavier or artificial atmosphere. This can be unpleasant or even trigger sensory issues for residents and visitors.

Practical solutions:
• Limit use of strong scents and avoid relying on air fresheners.
• Focus on source removal through cleaning, waste disposal and air movement.
• Where odours persist, use discreet air treatment systems with proven results to improve air quality without overwhelming fragrances.

Fresh air means more than just comfort

Care homes that effectively manage odours benefit from improved morale, greater visitor confidence, and better CQC inspection outcomes. Addressing air hygiene alongside surface cleaning supports the wellbeing and dignity of residents, while improving the overall standard of care.
