Quick choosing guide

1. Start with your source: municipal (chlorine/chloramine) vs well water—match filters or systems accordingly.
2. Pick the application: whole-home (showers, laundry, appliances) or point-of-use (drinking/cooking at the sink).
3. Size for flow: select system/house size to maintain pressure; match cartridge size (10", 20", “BB”) and micron rating to your goal.
4. Taste vs maximum reduction: high-flow carbon for everyday taste/odor vs RO for maximum dissolved-solid reduction at a faucet.
5. Plan maintenance: note change intervals (typically 6–12 months for cartridges; multi-year media on whole-home units).
