An aquarium filter is definitely not "optional".
It is a must for all fish species in captivity. Without a filter, toxic ammonia will build up since it is released by the fish on a constant basis. No amount of water change is substitute for a running filter system.
3 gallon is also too small. Ideally we need minimal 5 gallons of water to keep it in stable conditions. Most betta fish die young because people are misinformed about their basic needs.
