Water Filtration

Water Filtration for the whole home and at-the-sink. Shop complete systems, filter housings and cartridges, RO drinking water, and maintenance parts to improve taste, reduce chlorine/chloramine, and protect fixtures and appliances.

Featured brands: 3M, American Granby, Campbell, Elkay, EWS (Environmental Water Systems), The Source (twistIIClean), and Zurn Wilkins. Browse each brand below or filter to the exact type you need.

Shop by need

  • Whole-home systems: carbon filtration for city water; options with salt-free conditioning to help with scale (model dependent)
  • Under-sink drinking water: high-flow faucet filters, compact multi-stage kits, and RO (reverse osmosis) systems
  • Filter housings & cartridges: standard and high-flow sizes, sediment, carbon block/GAC, specialty media
  • Accessories & parts: install kits, valves, gauges, O-rings, wrenches, and replacement cartridges

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).

Pro tips: Install whole-home systems after the meter/PRV and before branches; bypass hose bibbs if you want untreated outdoor taps. Always flush new cartridges, keep spare O-rings on hand, and set a reminder for filter changes. Not sure where to start? Tell us city/well, pipe size, and what you want to improve—taste, odor, chlorine/chloramine, or scale—and we’ll dial it in.
