Is the WaterChef C6500 worth it?

For renters or small kitchens that can't install an under-sink system, it offers certified lead and cyst removal without plumbing. If you need fast flow or reverse osmosis, look elsewhere.

How often do I replace the filter?

The CR65 cartridge is rated for up to 600 gallons or about a year, whichever comes first. Heavy use will shorten that.

Does it remove fluoride or nitrates?

No. It is a carbon block filter, so it targets lead, mercury, cysts, microplastics and similar contaminants but does not remove dissolved fluoride or nitrates the way reverse osmosis does.

How fast does it filter?

About 0.75 gallons per minute at 60 psi, so a quart takes roughly 20 seconds.

The countertop unit with a pre-installed filter cartridge. No faucet adapter or extra cartridge is included.

Its best new price was $119.95 at Walmart as of November 6, 2026. Watch for seasonal sales and bundle deals on replacement cartridges.
