20x30x1 MERV 11 Pleated Air Filter

We have been using the 20x30x1 MERV 11 Pleated Air Filtes for about a. The filter does a very good job of trapping fust particles. Another positive is I do not have to remember to purchase a new filter. Filterbuy automatically sends me a replacement filter every 3 months. I recommend Filterbuy.

Only one question: why are the filters yellow on one side and light beige on the other. I have never seen a filter anything but white.
