10 field-tested tips
- 1Never mount above a return-air grille; the treatment vents outside without doing work.
- 2Never mount above a supply diffuser; the burst of cold air stops the fan-driven diffusion.
- 3Mount 6–8 ft above the floor for passive gels; 7–9 ft for metered aerosols in commercial ceilings.
- 4In restrooms, place opposite the entry so the treatment reaches the door swing.
- 5For open lobbies, use ceiling-height HVAC-integrated dispensing, not wall units.
- 6One dispenser per 400–1,500 sq ft depending on airflow, ceiling, and product intensity.
- 7Never point a fan-driven unit directly at people; guests feel targeted.
- 8In corridors, alternate sides to keep coverage even.
- 9For elevator interiors, use low-VOC discs, never aerosol.
- 10Document every location on a floor plan; turnover shouldn't reset the map.
Why it matters
Coverage problems often come from air paths, partitions, and operating schedules rather than an empty cartridge. A dispenser can leave an adjacent seating area untreated while concentrating product in a nearby alcove. Strong fragrance beside the housing is not evidence that the occupied space is covered. Check odor at the complaint location, not just at the device.
Practical steps
Walk the area with HVAC and exhaust operating under normal occupied conditions. Note closed doors, vestibules, tall furniture, and partitions that interrupt circulation. Check whether complaints change when entrance doors open or exhaust starts. Inspect the housing for blocked outlets, depleted product, leakage, battery faults, and incorrect settings. Keep units accessible for servicing without placing them where carts can strike them. Confirm product and dispenser compatibility against manufacturer instructions. After an adjustment, assess both the complaint area and neighboring occupied spaces before increasing output.
When to call a professional
Call a professional when coverage remains uneven despite working equipment, or when treatment migrates into tenant spaces. HVAC-connected equipment needs coordination with the building engineer or HVAC contractor. Persistent sewer odor requires source investigation, not stronger dispensing. Stop dispensing if occupants report irritation and investigate before restarting.
How Luften handles it
Luften offers a free on-site walkthrough to identify odor sources and provide a written treatment recommendation. Managed service programs and documented service visits support ongoing maintenance. Luften uses encapsulation chemistry rather than masking fragrance and provides service through in-house technicians.
