AO Smith Whole House Water Sediment Filter - NSF Certified

This system will not reduce total dissolved solids (TDS). However, the AO-WH-PREV system is certified to reduce sediment, dirt, and rust in your water, appliances, and plumbing fixtures, designed to provide sediment-free water from every tap in your home.

Properly tighten all fittings to ensure a leak-free assembly. Tools recommended include NSF approved PVC primer and glue, channel locks, thread seal tape, and a PVC pipe cutter. Do not install the unit on its side.

The built-in shut-off bypass valve allows you to change filters without turning off your water supply, and the pressure release button facilitates quick and easy filter replacements. This Whole House Filter System uses universal 2.5-inch replacement cartridges (sold separately) and can be used by itself or with additional A.O. Smith filtration systems, enabling you to customize your filtration setup to meet your home's unique needs.

Simple DIY installation is possible, as the package includes the filter housing, the first sediment filter, and a housing wrench. No plumber is required. The system is NSF certified to standard 42 for the removal of particulate matter.
