1. An ozone injector device comprising:
a) a housing formed by two halves removably coupled together, the housing having:
i) a water passageway through the housing, wherein the water passageway is a venturi having a water inlet and a water outlet configured to couple to a water filtration system for a pool or spa;

b) a corona tube disposed within the housing and configured to generate ozone;
c) a high-voltage transformer disposed within the housing and configured to electrically couple to a power source;
d) a check-valve having a first end removably coupled to the water passageway and a second end configured to receive ozone, the second end having a cavity with a movable float contained therein;
e) an ozone inlet fitting removably coupled to the second end of the check-valve, the ozone inlet fitting being in fluid communication with the corona tube via a corona discharge tube such that ozone entering the water passageway through the ozone inlet fitting must pass through the check valve; and
f) a spring-loaded clearing piston positioned to move into and out of the water passageway directly opposite the ozone inlet fitting, the clearing piston being biased upwards, towards the ozone inlet fitting, and configured to prevent flow of ozone into the water passageway.
