Air care decisions shape how a space feels to the people using it, plus how predictable it is to service and maintain.
They are influenced by placement, product format, intensity control and how long performance holds up between visits.
Air care means the planned use of fragrance delivery, bad smell reduction and placement to improve how a space is perceived and maintained. This hub shares research-led insight and practical guidance on air freshener systems, fragrance delivery and bad smells in commercial environments.

Ennovamark Air Care Insights is a hub for research and practical guidance on air freshener systems and fragrance delivery in real spaces. It covers passive and active formats, placement, intensity control, longevity, servicing and user sensitivity. The page links to our Scent and Behaviour Study and our Scent in Healthcare Environments study, with clear takeaways and practical notes you can apply when planning or improving air care in commercial settings.
You can also explore Innovation support and Marketing support.
· Choose format and placement together - the same product can perform very differently across spaces.
· Keep intensity controlled - over-dosing is a common trigger for complaints.
· Longevity depends on exposure, temperature and servicing habits, not just refill size.
· In care settings, lower intensity and clearer rules usually reduce risk.
· Air freshener formats - passive and active systems.
· Fragrance delivery - reach, intensity and consistency over time.
· Placement - washrooms, entrances, corridors, lifts and guest areas.
· User response - comfort, sensitivity and complaints handling.
· Operational reality - service intervals, change-outs and cost-in-use.
· Indoor air quality context - staying clear on claims and expectations.

A practical look at how scent can influence perception and responses in real environments, plus what that means for air care choices and messaging. Read the Scent and Behaviour Study.

In healthcare and care settings, air care choices tend to have less margin for error.
Patient sensitivity, staff exposure, cleaning routines and expectations around hygiene all influence what is acceptable.
This section will share practical notes on using fragrance in a controlled way, plus what tends to cause complaints and how to avoid avoidable issues.
A full research study will be published shortly.

Care settings usually need tighter control and a simpler approach than hospitality or retail. The aim is consistency without over-dosing, plus fewer conflicts with cleaning products or clinical expectations.
What matters most in practice?
A system that relies on natural air movement for output with no powered element.
A system that uses a powered element to increase output and improve consistency over time.
How output is limited or adjusted so the space is not over-dosed.
How often a unit is checked, cleaned or changed as part of routine facilities work.
How different people respond to scent, including discomfort, headaches and complaints.
Common questions about commercial air care, fragrance delivery and bad smells - with plain answers.
Air care is the planned use of fragrance delivery, bad smell reduction and placement to improve how a space is perceived and maintained. It works best when format, placement and servicing are considered together rather than as separate decisions.
Passive systems rely on natural air movement. Active systems use a powered element to increase output and consistency. The best choice depends on space size, servicing model and tolerance for visible hardware or noise.
Complaints are often caused by over-dosing, poor placement, mixed smells, sensitivity issues and products that change character as they run down. A simple fix is to reduce intensity, adjust placement and set a clear feedback process. Read the Scent and Behaviour Study.
Start with cleaning routines and sources of bad smells, then use air care to support perception rather than mask issues. Choose a format that stays controlled over time and place it where air movement supports even distribution, not hotspots.
