Provided is a manually operated nasal aspirator having an elongated cylinder body and a piston. The cylinder body has a sidewall, a nozzle at a forward end, and an elongated slot extending longitudinally in the sidewall to a rearward end. The piston is configured to slide within the cylinder body between first and second positions and has an actuator laterally extending therefrom through the elongated slot. The piston is manually movable between the first and second positions by a user and is not biased by any other means so that it will rest at all positions between the first and second positions when not being manually manipulated. The cylinder has a length sufficient to fully contain the piston therein in both the first and second positions.
