The invention relates to a nasal aspirator which is used to dislodge and remove secretions, mucus and debris from a nasal passageway of the user. The device is provided with a housing, one end of which is adapted for mounting on a faucet of a liquid fluid source. The second end of the housing serves as an outlet of the device. A vacuum container is in fluid communication with the housing in such a way that opening of a fluid source through the housing causes creation of at least partial vacuum within the container. A nasal valve is in fluid communication with the housing and the vacuum container. The nasal valve includes a nasal seal, one end of which is positioned in the nasal passageway and which is carried by a tube, the second end of which unseats the valve element of the nasal valve to open the fluid communication between the nasal passageway and the housing. The rapid manual opening of the nasal valve causes creation of an impulse, or explosive shock which dislodges secretions from the nasal passageway and moves them towards the outlet of the housing. Continuous water flow through the housing insures continuous application of a suction force until such time as the nasal passageway is secretion-free.
