SFC100 – For the SF100 Filter
The SF100 replacement cartridge uses a 12-stage media stack: KDF-55, calcium sulfite, activated carbon, and ceramic beads. It targets chlorine, chloramines, heavy metals (lead, iron), and scale-causing minerals.
Replace every 6 months under normal household use (one or two people showering daily). If you notice a sulfur smell, reduced water pressure, or your skin and hair feel noticeably drier, it is time to replace earlier.
SFC220 – For the SF220 & SF500
The SF220 uses a 20-stage cartridge – the same housing dimensions as the SF500 HD. The SFC220 cartridge adds Maifan stones and tourmaline ceramic to the 12-stage stack, which supports a longer service life (6-8 months vs. 6 months for SFC100).

See Reviews on AmazonWhen to Replace Your Cartridge
AquaBliss recommends a 6-month replacement schedule based on average household use. The cartridge has no electronic indicator – you replace on a schedule, not a sensor. Set a calendar reminder when you install a new one.
- Every 6 months (standard) – 1-2 person household
- Every 4-5 months – household of 3-4 or area with very hard / high-chlorine water
- Replace early if you notice: rotten-egg odor in shower, reduced water flow, dry skin/hair returning
How to Replace the Cartridge (2 Minutes)
- Turn off the water supply or wait until after a shower so the filter body is not under pressure.
- Unscrew the filter body (bottom half) counter-clockwise by hand or with a strap wrench if tight.
- Pull out the old cartridge and discard it.
- Rinse the inside of the filter housing with water.
- Insert the new cartridge with the label facing up (check arrow direction).
- Screw the housing back on clockwise – hand-tight only, do not over-torque.
- Run water for 2-3 minutes to flush carbon dust before your first shower.

Frequently Asked Questions
How often should I replace my AquaBliss filter cartridge?
Every 6 months or 10,000-12,000 gallons, whichever comes first. In hard-water areas or large households, 4-5 months is more realistic.
Can I use SFC220 in an SF100?
No. The SFC100 and SFC220 have different dimensions and media stacks. Using the wrong cartridge can cause leaks and poor filtration.
Is the 3-pack worth buying?
Yes, if you plan to keep your SF220 or SF500 long-term. The 3-pack works out to about 15-20% less per cartridge and covers 18 months of typical use.
