have you guys even seen a trf filter? how can u even judge a filter you've never seen..... im my opinion the trf came out cleaner than the regular filter i used to use.... everytime i use the old filter it gets dirty really fast... i will post pics of the filter that i used in the 7m for at least 3 years

So what do you think happened to all that dirt if it didnt stop at the filter?
