Installation
Estimating Cartridge Life
Estimating how long a cartridge will last and the number of days between services is critical to
performing an installation that can be serviced efficiently. This includes determining the number of
AQ880s needed for a space. Please refer to AirQ’s ‘S4 (Sizing, Service & Success) Tool,’ available at
AirQTools
. The chart below can be used as a rough guideline for sizing.

These settings are suggested as a starting point. Start on the lower end of the range and adjust after
one hour. Fragrance type, room size, number of fresh air changes per hour, temperature, humidity
and user preference will determine the final setting. Best practice is to use AirQ’s ‘S4 Tool’ at
