    A water filter cartridge is the most critical part of an adequate water filtration system. The cartridge in water filters removes all impurities from your drinking water. It eliminates everything from large particles like dirt, rust and silt to smaller particles like organic matter and minute bacteria. PSI has a vast range of replacement water filter cartridges for various systems. Browse our site today!

    Our Recommendations for Water Filter Cartridges

    We've put together a few recommendations for water filter cartridges that we think are great options.

    For Chlorinated Water Supply

    • Any sediment filter can be used typically in a 5-micron option.
    • Opt for refillable carbon water filter cartridges in a Chloramine option or coconut-based cartridge.
    • Use Matrikx CTO as a basic extruded carbon block in 5 micron.
    • Use Aragon as a broad range of filtration — it’s second to none.
    • Try Matrikx PB1 for a lead and heavy metals rating.

    For Tank, Creek or Dam Water Supply

    • Try a silver-impregnated carbon water filter cartridge in a refillable style.
    • Use Nanosilver for a throwaway style with extruded carbon block or Siam cast.

    FAQs

    How do water filter cartridges work?

    Water filter cartridges are typically made up of a carbon block, which works to remove contaminants from your water. The block is housed in a casing that allows you to easily replace the cartridge when it reaches the end of its useful life.

    How do you change a water filter cartridge?

    Most manufacturers have made the replacement of water filter cartridges super easy. You just need to:

    1. Turn off the faucet.
    2. Pull out or twist off the old cartridge by hand.
    3. Insert the new filter in the same way as the old one, ensuring it's fully inserted into its housing.
    4. Turn on the faucet and check for leaks.

    How often should drinking water filter cartridges be replaced?

    We recommend replacing your drinking water filter cartridges every 12 months.

    Why should I buy water filter cartridges from PSI Filters?
