FAQs

Will a whole house filter reduce water pressure?

Quality systems like the Aquasana Rhino maintain normal pressure. Cheaper filters or clogged filters can cause pressure drops. Look for systems rated at 15+ GPM.

Do I still need under-sink filtration with a whole house filter?

For most people, no. But if you want absolute purity for drinking water, adding an RO system at the kitchen sink provides an extra layer of protection.
