WATER FILTER TIPS

This is a recommended filter replacement schedule:

Six months for whole house cartridges, under-sink carbon filters, and reverse osmosis pre-filters.

Twelve months for secondary cartridges and reverse osmosis post-filters.

Three years for reverse osmosis membranes. This depends on water quality and usage. When rejection rate drops below 80% membrane should be replaced. Bring filtered and unfiltered water samples in for free TDS test and rejection calculation or purchase your own TDS meter to measure membrane performance.
