# How do I maintain my CrewProtect and StationProtect air filtration units?
## This guide covers the basic cleaning, cartridge replacement, and filter maintenance steps for TFT’s CrewProtect and StationProtect air decontamination units. Routine upkeep ensures maximum performance and longevity, without any complex service steps.
Proper maintenance of your air decontamination units is key to keeping your fire apparatus and station air clean. This guide outlines basic steps to replace filters, wipe down components, and ensure the system stays operational over time.
### Maintenance Overview by Model

2. Discard old cartridge (can be thrown away).
