Why is the water from your bathroom faucet cloudy and rest of running water in the house is clear?

Aerators are helpful to keep water from splashing, they also infuse air into running water. If you see that the water is cloudy, try this... Take a clear glass and run cold water from the tap, for a second, then place the glass under the faucet, fill the glass and set in on the counter. If the water is being effected by the aerator the cloudiness will dissipate in a few seconds. The cloudiness is tiny bubbles suspended in the water.
