The "crud" is not from the hose. The reason you don't need a filter with "some" hoses is because those hoses have regulators on them which limit the pressure of the propane (and according to some...filter out contaminants???.....I think they just limit the pressure). High pressure hoses (without the regulator) move the oil in the propane (mercaptin oil I believe) which is an additive along with the odorant of the propane into your heater. Degree of contamination varies by your propane source. I understand from a few people that if you don't use the filter with the bulk tanks you will cause parts of your heater to be permanently damaged after time....
