Frequently Asked Questions

How is ChloraShield different from the standard green coconut carbon filter?

ChloraShield is rated to 1 micron and is specifically engineered to remove 100% of chloramine, which standard carbon filters cannot fully eliminate. This makes it the better choice for growers on municipal water systems that use chloramine disinfection.

How often should I replace it?

Follow the replacement interval for your BIGboy system, or sooner if you detect chlorine or chloramine taste or notice a flow reduction. Keeping to this schedule protects your RO membrane from chloramine exposure.

Is this made in the USA?

Yes -- ChloraShield filters are manufactured in the USA. Manufacturing domestically supports consistent quality control on each cartridge.

Can I use this if my source is well water?

Yes -- the 1-micron rating still provides strong particulate removal even without chloramine present in the source water. Well-water users benefit from the fine filtration even though the chloramine-removal feature goes unused.
