I found the following:
"Easy To Access and Clean Filter. The Rheem Classic® 90 Plus® is equipped with a permanent, washable filter thats easy to access and clean. You wont ever have to deal with the hassle and expense of replacement filters."
That said, the factory installed filters may not be the best at filtering out dust and allergens so you may want to replace it with a HEPA pleated paper filter.
You should be able to call this company http://www.repairclinic.com/Rheem-Furnace-Filter-Parts to find the right size.
