Quality supercardioid microphone will reject echo well enough for most rooms and a meter or two distance. That is usually enough distance to not typically require a pop filter, this giving improved clarity. Hypercardioid "shotgun" works too as long as its back is placed far enough off a wall, however these tend to have sound coloration. It just so happens that most microphones are the less directional cardioid. Or worse, omnidirectional.
