The cloudiness you’re seeing is simply trapped air being released in tiny bubbles. Iron filters use air to oxygenate your water and remove iron particles. In the process, some air is left in the water and can come out of the faucet, temporarily making water appear cloudy. It’s more common for newer filtration systems, which use more air while the system “breaks in.” This is an expected, harmless effect of the filtration process and doesn’t require any special service or corrective action.
