The simple answer is to allow the water to off gas before it’s pressurized and run into your plumbing. This would be done with a large atmospheric storage tank or (break tank). You should use an automatic chlorinator to disinfect the water after the storage tank. This will also oxidize any of the iron making it easy to filter out.
Remember you are dealing with your drinking water and should have a basic understanding of water chemistry. This may not be the solution for your water without seeing any test results or the configuration of your system.
