what is the reason for only installing on the hot water line? Would like to use for entire house, cold water also.

Hi, Thanks for your interest in our AP431 filter product. Please note that this is only designed for cold water line; it is designed to protect water heater placed after it, thank you.

Are other parts or items needed? Or can you really filter your entire house water with just this? Where do you install it?

Hi, Thanks for your interest in our product. Please note that this is a scale inhibitor. When using this scale inhibition system, we recommend installing a pre-filter as well.You need to install it behind the water meter. https://www.amazon.com/dp/B08XXJSN29/ If you have any other questions, please feel free to contact us.
