I, like all other RS4500 users, have a lot invested in my projector but maybe unlike some, expect it to be my last ever projector. I'm willing to spend the money necessary to minimize the chance of any issues. I have an excellent air purifier I will be moving into my theater to run when I am not in it and just purchased the one Kris Deering suggested for my equipment room. Unlike you, I have LOTS of dust in the theater room but less in my equipment room since I have a dedicated mini-split for that room!
Advice DIRECTLEY from JVC was to NOT use a compressor on the filter elements.....they advised to wash them in luke warm soapy water and let dry. They said micro particles get embedded in the filter elements by using compressed air, thus the reccomendation to wash instead.
I purchased several of the Filter assembly,s i change them over, wash and let dry then place them in storage fro the next rotation.
Running 2 Air purifiers helps DRAMATICALY ! with dust control......easiest way to look for dust content in the air is to look just in front of the lens when the projector is on.....i now hardly ever see any dust particles since using the Air Purifiers..
Like you....my Z1/RS4500 is here for the Long Haul!
