Depends on what you need to filter for.
If you're on city water, you can typically look up the city's water quality reports to know what you're filtering for, over and above what they deliver. In my area, I'm just filtering for taste. So, reading their specs, the Circle system is rated at 3,500 gal. Aesthetic Chlorine (for taste). But if you're filtering for VoCs, it's rated much lower, at 243 gal.
