If I leave Water Out For 24 Hours, WIll It Be Safer To Give To My Plants?

I own a Bromeliad, A Peace Lily And A... Mixed Fern Thing (not sure waht it is but that's the only name that come to mind for some reason). I use to own a Venus Flytrap and I had to give it bottled water because it needed pure water. So I heard I can just leave tap water out and it would be just as safe. Is this true? I don't own the Venus anymore, but I still wanna know if it would be safe to give that kind of water to it in case I buy another. Will my Lily, Bromeliad and Fern be ok with tap water if I leave it out?
