This Master Deluxe spa filter model M40508 is made from quality Reemay brand filter fabric. 

This type of filter for Arctic Spas is used on many 2009+ Arctic hot tub models.

Note the female threaded socket size is listed as a nominal pipe thread size of 1-1/2″, but that is not the actual measurement of the inside diameter.  This  1-1/2″ coarse threaded socket actually measures about 1-7/8″ inside diameter (I.D.) for your reference.
