One of the biggest problems with the comon stock filters found on 1/5 scales is that the have a large amount of area where the filter meets flat plastic. This is a problem because anytime you have a filtering surface against a flat spot there is a good chance dirt and debris will sneak into this area. This is why for years motorcross guys (and experienced R/C guys) have ran grease between these areas. A exlcusive feature found on the DT1 filters is a special neopreme material in this area called Super Seal. When the Super Seal is oiled it becomes super sticky and forms a seal between the foam and flat plastic areas. A feature only found on DT-1 filters.
