ESTIMATE CARTRIDGE COST
Annual filtered volume V (U.S. gallons):
Cartridge rated capacity C (U.S. gallons):
Cartridge price P (dollars):
Volume-based count = V / C, rounded UP to whole cartridges.
Check the manufacturer's time limit too; it can require more changes.
Annual cartridge expense = actual required count x P.
Exclude or separately add pitcher, water, tax, shipping and other costs.
Compare only compatible options meeting the intended reduction requirement.

FICTIONAL EXAMPLE (not current product prices)
V=240 U.S. gallons/year.
A: C=40 gallons, P=$7. Volume count=6; expense=$42/year.
B: C=120 gallons, P=$20. Volume count=2; expense=$40/year.
Cost/rated gallon: A=$0.175; B=about $0.167.
Time-based replacement can increase cost at low usage.
