One of my blower filters broke off and fell into the tank I just noticed this it's been 2 weeks since the last time I clean them couldn't have done any damage should the blower in this time and am I OK to run it temporarily until I get new ones
 
I figured it would be OK anyone know where I can get these filters I'm going to replace both of them and my old bane machine that my dad ran for years add a little 3M blower and never had a filter
