A water injector for an aviation cooling system includes a body having a first end, a second end, and an intermediate portion extending therebetween. A conduit extends through the body from the first end to the second end. A spray nozzle is fluidically connected to the conduit and arranged at one of the first end and the second end. A mounting plate is arranged at the other of the first end and the second end. The mounting plate is configured and disposed to secure the body to an aviation cooling component. A filter is supported at the body and is fluidically exposed to the conduit. The filter is configured and disposed to capture particulate flowing into the water injector towards the spray nozzle.
