Define small?
If your unfiltered tank is less than 3.5 US Gallons I would recommend a 100% water change every 3 days.
Anything higher than that and you really do need a filter. Bettas can live in small spaces but that doesn't mean they're thriving. They're still fish and need space and quality water. It also means you can just do gravel vacs and partial water changes.
I personally wouldn't keep a betta in less than 4 gallons, and preferably 5.

Bettas have a lifespan of 3 to 4 years. They are usually around a year when they land in the pet store, as they don't come into their color until they are a year old. Therefore, you can expect your betta to live 2-3 years. I would suggest upgrading the tank to something larger, filtered, and heated. Contrary to popular belief, bettas are tropical fish and much prefer a heated tank.
