Whole House Water Filter Systems
A complete whole house water filter system treats water at the point it enters your home — so every tap, shower, and appliance receives filtered water, not just one faucet. This collection covers complete systems and multi-stage setups, not individual housings or cartridges. If you're looking for a standalone replacement housing, visit our Water Filter Housings collection instead.
Systems available here fall into three categories:
- Multi-stage Pentek systems — pre-assembled 2 and 3-housing setups ($243–$337) ready to accept your choice of cartridges, ideal for layered sediment and carbon filtration without building from scratch.
- Whole house GAC and catalytic carbon systems — Tier1 units ($289–$497) designed for chlorine and chloramine reduction at high flow rates, treating 300,000–450,000 gallons over the system's life.
- Water softeners — Tier1 Everyday Series ion-exchange softeners in 32,000, 48,000, and 64,000 grain capacities ($509–$749), addressing hard water throughout the entire home.
