When Should You Replace a Filter?

Simple considerations to help maintain a water system.

Sediment pre-filters and carbon media beds gradually load over time depending on household water volume and local municipal or well supply conditions.

PURWTR simplifies upkeep with a 6-month reorder reminder so you can order replacement filters in one click and optionally dispatch a licensed local plumber to perform the swap.

• 6-month filter reorder cycle: automated reminder email every 6 months with one-click filter reorder.
• Optional licensed plumber dispatch available when reordering replacement cartridges.
• Filter subscription pricing: TBD (placeholder until recurring cartridge rates are finalized).
• Post-install labor warranty window (60–90 days, exact terms TBD) for reporting any installation issues.

Note: Filter subscription pricing and warranty window terms — TBD.
