Stupid question guys but I can't seem to get the filter off. I tried unscrewing the clamp from the filter and I thought it would slide off but was unsuccessful. Can anyone tell me if there's something else that needs to come off?
Thanks,

Here's a picture that I found online. I placed an arrow where I removed the clamp but it's still not coming off.

 

if it has been on it for long time/ you might need some elbow grease to pull them out.
try pressing it down give it a jerk of a torque, but make sure you unscrew them enough

 

Man I tried to take it off and it was ridiculously tight. So I guess there is no other bolts or screws to unscrew?

 

No, just the clamp, after loosening enough so the clamp can freely revolve around, grab it by the end cap and move it up/down left/right a little, work it around and it should help unstick it. Once off a leaf blower works good to blow the dust and particles off, stick it in the insde and blow out. Can be washed in water as well, I used a mild mix of car wash soap and then rinsed thoroughly.
