How long do angelfish live without a filter?

It depends. Lots of fish can live without a filter but, the wont live as long. Do you plan on buying it one again? If you don't then it wont live as long. It might live 1-1 half months. How long has it lived without a filter? If a long time then i'd go buy on eright now, if you care about it. If it hasn't had a filter that long then you should still go right now and buy it one. But, if you are broke then, you can wait. I hope I could help.

Answer

Get another filter as soon as possible to keep your fish healthy. If you can't afford it, possibly you need to find them a new home.
