Mountain Pure MT6K-HF/RFC FAQ

How often should the MT6K-HF/RFC cartridge be replaced?

Replace the cartridge once every 12 months or after filtering 6,000 gallons of water, whichever comes first. If your local water has high particulate sediment, replace sooner if flow noticeably decreases.

What contaminants does this filter reduce?

It reduces harmful contaminants down to 0.5 microns—including PFAS, lead, pathogenic cysts, VOCs, pesticides, chlorine taste and odor, asbestos fibers, rust, and heavy sediment—while keeping beneficial minerals intact.

Is this cartridge compatible with Everpure® filter heads?

Yes, it fits Everpure® single heads equipped with a collar (models QL2, QL3, and QL7I). It is not compatible with QL1, QL3B, or QC7I multi-cartridge manifold heads.

No. The MT6K-HF series is designed for full-flow operation, allowing it to connect directly to your existing main faucet without needing a separate secondary dispenser.
