The difference
What each option actually means
Point-of-use filtration targets selected drinking-water outlets; whole-house filtration treats water entering multiple fixtures.
The trade-offs
The right option depends on the goal, available space and ongoing maintenance.
How to decide
Define the concern before paying for a larger system than needed.
Before choosing
A plumber should assess suitability, condition, access and applicable requirements. Product or repair recommendations made without seeing the property are preliminary. Ask for the proposed scope, exclusions and relevant warranty details before approving the work.
