Multiple application of LinearFilter

Hi All,
 
I have been using LinearFilter on my data with great success & achieve
better results the more times I pass my data through the LinearFilter. (
I have had to adjust data length to maintain correct indexing with
PadLeft - but this is not my question here.)
 
Below is how I am applying the multiple LinearFilter.
 
EG
 
originaldata
 
Data1=LinearFilter[originaldata, {1/2,1/2}];
Data2=LinearFilter[Data1, {1/2,1/2}];
Data3=LinearFilter[Data2, {1/2,1/2}];
 
 
My question is - Is there a shorter way of writing multiple passes of
the above.
 
If there is a way, please show the code.
 
It would be great if I could simply adjust the number of passes from say
three above to any number of passes to find optimum setting for data.
 
Many thanks for your attention.
 
Best Regards - Lea Rebanks...
