This post will show you that how to clean a projector filter. It is actually an easy process and will only take you a couple of minutes. I demonstrate the process with a specific projector, but the process can be pretty much replicated with any projector that you have because they all work in a very similar manner. With that being said, you should be regularly cleaning the projector filter because a dirty filter can cause some problems and it can even make the entire projector stop working.
