I can only add about Filters is this:

When I was younger I had no filter. I said what I wanted and how I wanted to say it. Opinions...oh ya I had many and I let them spew out like 10w 30 on a 100 degree day.

I lost many a fiend, a tooth or two and a few nice lady friends.

Later on a started to Filter my thoughts and tried to be more of a gentleman. I had much more quality relationships with the filter..

..so by all means filter it..even if you can take out a little dirt...you will get more pleasurable miles.
