As long as you ISOLATE the PATTERN you are trying to catch, you don't need to change the filters. FOR EXAMPLE, if you want to catch a DOUBLE, you ISOLATE the DOUBLES like above then use the filters and DON'T change them until another DOUBLE hits.
THEREFORE, you can play the same numbers for multiple draws at one purchase.
NOTE: but keep in mind, after every draw, the numbers could jump from one PAIR and HIT/MISS pattern to another. THUS, if you are playing all the remaining numbers no problem. BUT if you are trying to catch a specific PAIR or HIT/MISS pattern then you need to grab the numbers before each draw.
