The 90's and extensions did wonders for the sound level. It's noticeably quieter than my oil less now. I'm using the HF filters that came with it, they are just 3/4"npt male threaded housings. I have thought of using a 'better' filter at some point in the not to distant future, but I'm not sure what that would be. Most likely just a quality name brand filter with 3/4 threads.
