Quiet 5 gallon filter?

So I need to know of a QUIET (preferably silent, but very quiet I can work with too) 5 gallon filter. I have a 2.5 tank with a tetra whisper filter and I honestly hate the thing because of how little it filter and it's stupidly loud for how small it is (the filter is supposedly only for tanks 1-3 gallons big).
