My Vent Axia Sentinel Kinetic came with the filters looking like this (see photo!). The whole system seems pretty clogged up (see next photo - you can see dust clogging up the pipes) , so I think I need to clean out the system. This is my first home renovation project, so I'm excited to get going but not sure what to do. Does anyone have any tips on cleaning the system out? Not sure if this makes a difference, but I'm renting, and the landlord probably won't do anything about it, so I'll have to. Does anyone know if this is something they have a duty to take care of?
