After viewing a review of the product on YouTube, I came to the conclusion that the filter that has flasks that are see-through is the superior option. There, the filter flasks are secured with a cap plastic sleeve, just like an aquaphor would be in a primary filter; however, this method is significantly more practical. Rubber gaskets will last longer. And any brand of filter can be used there because they are interchangeable.
